I've installed the previous mods Soundcheck put on his Blocg and can say they make a good improvement.

The second version of his mods look even better...
worth a punt for sure.

Can you elaborate some more on what kinds of improvements have you noticed (as well as what kinds of improvements have you attempted)?

I've only tried forcing the SB server to convert FLAC to PCM before sending to the Touch, and it made audible improvement for sure.

Curious to know whether abandoning WLAN for Ethernet is worth the hassle...

No worries Alex...I THOUGHT you'd be one of the guys to notice the post... ;)

Like yourself I found getting the server to decode Flac (rather than the Touch doing the number crunching) made an improvement.

This is where the Soundcheck mods are coming from, stripping the Touch's workload back to the bare minimum.
His Linux scripts from the first version of the mods basically switched off unnecessary startup services making the most of the small CPU and memory resources of the Touch.

The new ones (available Sunday 9th apparently - he's sanity checking them before he puts them out there...) prove to go a step further, by switching OFF the Touch's display, which according to himself and john Swenson (He who is to be trusted in all matters Squeezebox...) makes the biggest improvement.

Like Soundcheck says on his blog, the mods he proposes reduces the functionality of the Touch to that of a Duet, but I use Ipeng on my Ipod Touch to control my music anyway, so if the improvement with the screen off is a big step up it wont be TOO much of a problem.
That said, I glance at the Touch to look at whats playing, how long to go etc, so maybe it will be a step too far.
But if its an improvement in sound worth keeping...great!

I found the mods gave the Touch more detail and the soundstage was better defined and more 3D.
There was less "hash" in the sound with the treble sounding smoother but more incisive.
Overall not night and day...but very worthwhile to eek the most out of the Touch.

Well worth trying and easily reversible with a Factory Reset.

Just out of interest Alex, another good "free" improvement IMHO to the Touch's sound is to upsample 44Khz redbook Flacs to 96Khz using the SOX within Squeezecentre.
More solid sounding with more air around instruments, particularly noticable with orchestral/live recordings.

Its just a matter of adding a text file in the Squeezebox directory on the server and changing a setting in SqueezeCentre itself, restarting the server and your done.

Hope this helps,
Gaz

I'll be trying all this too, fairly soon I hope. just waiting for a copy of XP to arrive, and I'll be flattening my old laptop, put the new XP on,and using it to run squeezeserver. Been used to the sound of the Touch as a standalone player, so it will be interesting to hear the differences.

Wha-hey!

OK, first off, please send me more details on how to add a text file in the Squeezebox directory and how to change the setting in Squeezecentre. Would love to try that tweak!

I've been messing with converting some red book CD tracks to 24 bit, but I'm not able to detect any difference. Perhaps this tweak with increasing the sample rate will be more pronounced?

Like yourself, I'm not sure if I'm willing to sacrifice the utility of the Touch screen -- I am used to glancing at it for a quick info, rather than lifting my remote control.

What I'm mostly interested in is disabling the analog outs, and checking whether it makes any improvements. Have you tried that?

Another thing you haven't touched upon (no pun intended) is the WLAN vs. Ethernet. Is the difference that noticeable? I'm asking because going to the Ethernet might be a huge hassle for my listening room configuration.

Have you replaced the PSU on the Touch?

************************************************** ****************
about the Upsample with SOX tweak...


You need to create a new text file with the following text in it
(just copy and paste everythng between the dashed lines)

---------------------------------------------------------------
flc flc * *
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dc --totally-silent $START$ $END$ -- $FILE$ | [sox] -v0.95 -D -q -t wav - -t flac -C0 -b24 - rate -v -s -M -a 96000
---------------------------------------------------------------
(dont include any spaces after the "96000" as it wont work if you do)

when you have that pasted into a text file save is as "custom-convert".conf NOT "custom-convert".txt
(In the "Save As" dialogue (when saving your text file) You need to change Save as Type:Text Documents (*.txt) to "All Files" and change File Name to custom-convert.conf - MANUALLY type in.conf...)
ok?

in Windows 7/Vista it gets saved into "C:\Program Files (x86)\Squeezebox\server"
I'm not sure about the file location for Windows XP?
************************************************** ****************

I've been messing with converting some red book CD tracks to 24 bit, but I'm not able to detect any difference. Perhaps this tweak with increasing the sample rate will be more pronounced?

The reason your conversion to 24 bit on some Flacs doesnt make much difference is that the SB Touch AUTOMATICALLY converts all 16/44 Flacs to 24 bit!
Upsampling the Sampling Rate (as opposed to the Bit Depth will actually DO something ;))

Like yourself, I'm not sure if I'm willing to sacrifice the utility of the Touch screen -- I am used to glancing at it for a quick info, rather than lifting my remote control.

What I'm mostly interested in is disabling the analog outs, and checking whether it makes any improvements. Have you tried that?

Yes I have.
I tried that as part of the overall changes to the Touch that Soundcheck recommended, so cant comment honestly on that individual tweak, all I can suggest is to say JUST DO IT...and dont try to think too hard about it beforehand.
Let your ears be the judge :)

Another thing you haven't touched upon (no pun intended) is the WLAN vs. Ethernet. Is the difference that noticeable? I'm asking because going to the Ethernet might be a huge hassle for my listening room configuration.

See the above...:)
I had wireless issues in my house since Day 1 as I have 10 inch stone walls throughout my house and WiFi just isn't geared to work with that!

Have you replaced the PSU on the Touch?

Haven't done that yet Alex..if I will at all.
Conflicting opinions on this one, a bit contentious to be honest.
I know linear PSU's CAN make a difference..I noticed this with my Caiman when I fitted a linear PSU with that....but the Sb Touch is different in that it has switching Regs inside it already..kinda making a linear EXTERNAL PSU redundant.

That said, I've fitted Mutara Regulators to my Caiman to great effect..they are Switchers and STILL....the Linear PSU is an improvement with the Caiman.

So I'm, still open minded on that one personally..but I'm not shelling out £000's on a Teddy Pardo (etc) supply on a "What if??".

Thanks a million, Gaz. I'm with you -- Teddy Pardo PSU more expensive than Touch itself, what's the point? If it makes that much of a difference, I'd rather spring for the Transporter.

Speaking of Transporter, I seem to recall that someone somewhere had made some serious comparisons between Transporter and the Touch into Caiman. Couldn't find the winning/losing side, declared the listening match a stalemate. I'd be curious to hear if the same comparative test could be now done between the Transporter and the Touch into gatorized Caiman? Judging from my initial impressions (as of last night/this morning), Touch into gatorized Caiman via digital coax is now seriously pushing the sound quality into the esoteric, multi-thousand dollars audiophile paradise. Curious to hear whether Transporter could keep it up with this new kid on the block?

About the Caiman/Touch Vs. Traspoorter?

Its was a fellow AOS'er who used his Transporter into a STOCK Caiman as he found the overall sound quality better than the Transporter itself...

now,
couple THAT with the generally recognised opinion over on the Squeezebox forums (and I'm NOT paraphrasing - check it!) that starting from scratch most folk would spring for a Touch with a quality Dac rather than shell out for a Transporter, and you start to form a picture...

...and that was with a stock Caiman.

with your Gator Caiman and a Touch using Soundcheck Mods....your getting maximum bang for your buck.
Dont worry about how much bang for buck as compared to whatever.... ;)....just enjoy it.

The Caiman/Touch combo is one of those things you could spend $$$ trying to better...(as oppsed to make "sound different") best be happy with what you have till the next evolution comes along.

How much will 1 TB solid state memory be now?

Consider this: I am keeping my music library (some 350 GB and growing rapidly) on 4 external 1 TB drives, just in case Mr. Murphy decides to pay me an unwanted visit. I'm now thinking about getting the 5th hard drive because one can never be too redundant with that shitty piece of technology (basically, the weakest link in your computing chain). The storage cost adds up in a hurry.

Maybe the day will come when it will make more sense to switch to solid state? You know, no moving parts, no cooling fans...

no an internal one.
They are of the 2.5" format, which means they will slot in a laptop no probs.

In my case, I fitted a 60GB one as my windows drive which made ALL computing stuff be INSTANT.
Open a program..it opens before you let go of the key on the keyboard.
Windows boots up in less than 10 seconds.

With a laptop its different I reckon, but with a desktop you fit a SSD to install windows on and use a traditional HDD to store all your stuff...

A laptop has one hard drive..I'd be temped to fit a SDD if I had one, but a 100MB SSD is still really expensive....

Wow, interesting. I must be behind with the program (read: retarded); I still thought that Transporter is considered bee's knees.

Great to learn that us poor working stiffs armed with nothing but a $300 Touch and a $400 gatorized Caiman can now kick ass on pretty much all these boutique multi-thousand dollars esoteric DS machinery.

Hi Gaz,

You need to change Save as Type:Text Documents (*.txt) to "All Files" and change File Name to custom-convert.conf - MANUALLY type in.conf...)

Hey Jerry :)

when saving text files theres two things you can change:
"File Name:"
and
"save as type

you've already changed "File name" to "custom-convert.conf", which you need to do...but you also need to "Change as Type" from Text Documents(*.txt( to "All Files"...THEN save your file...

I just meant that BY DEFAULT anything you type into a text doument is saved as "text document" (*.txt) BUT you can save what you type in there as ANY type of file...you just need to click on the grey bar to the right of "Save as Type" (when saving your file) and change it from "Text Documents (*.txt)" to "All Files".

Hi Chaps,

Very interesting stuff, still trying to get my head round what you're up to...

Correct me when I go wrong;

1. You've done some software mods on the Touch to make it a more efficient 'client'
2. You're using the touch purely as a 'client'
3. You've added a SoX plugin to SqueezeServer which is up sampling everything to 24/96 pcm (is that the right term), and streaming that.
4. You're going to hard wire the touch via the Ethernet port. Probably essential because of 3

Now how does this affect my world...(he said in a selfish manner!)

In my main system I take the digital out from a receiver into my Audiolab 8000DAX (max sample rate is 48k), I've done plenty of A/B testing and can not differentiate between the receiver (playing FLAC), and my CDM cd transport.

So upsampling to 96k is futile for me at the moment due to my DAC limitations

I'm using 2 SB receivers, and one SB3, so bandwidth might be an issue, if I were to upsample there would be an increase in traffic of about 400%. So hard cabling would be essential.

I'd be interested in your comparisons between standard CD playback and the upsampled FLAC version (sorry if I've missed this already).

It would also be interesting to compare the standard receiver vs the standard touch as a DAC source playing 16/44.1 redbook, sounds like the touch may have a few too many bells and whistles, probably bad coding by logitech.

I've been trying to find the device specs for the receiver vs the touch but logitech aren't very forthcoming, as they are mini computers it would be nice to see their processor and memory specs.

I'm having a Jonny Nash moment :scratch:

Hardware details
http://wiki.slimdevices.com/index.php/HardwareComparison

Be aware that the Wolfson WM8501 DAC in the Receiver is a 24-bit 192 KHz BUT the CPU in the receiver is not able to handle the load; hence the default rules in the SBS server is to transcode (SoX) when playing highres on a Receiver.

WAD62

Hi Jan,

Cheers for the info...

I've got 2 receivers (one into an additional DAC), and an SB3 (that uses the Burr-Brown PCM1748E which I think is 24/96 capable).

I thought I'd spotted that somewhere, re. the receiver's DAC hi res capabilities. Have you used it at a higher resolution?

I'm using 7.3.3 (SqueezeCenter) on a linux platform, and SoX is conspicous by its absence, what version of SqueezeServer are you using using 7.5? And is SoX bundled in with it, or is it an optional plugin.

Given that the DAC on my main system (Audiolab 8000DAX) is only capable of a maximum of 24/48 upsampling is rather pointless for me at the moment, but it might prove useful in the future.

Edit; One further thought, what are the implications of upsampling via SoX with respect to ReplayGain? (answered my own question below

Edit#2; I also run winamp against the same FLAC library I use for my squeezeboxes, this goes into an M-Audi 2496 soundcard.

There's a SoX input plugin for Winamp, FFSox, now downloaded and installed, with some very interesting results...

Firstly when checking my current playback form the M-Audio mixer I spotted that it was at 48K, I'd used the default settings which was using the Multi media codec and not the stereo one. So after switching to the stereo codec I was back to 44.1, with a noticeable improvement.

FFSoX for winamp page;

http://in-ffsox.sourceforge.net/

FFSoX is an input plugin, which provides not only upsampling capabilities for multiple file types, but also respects replaygain both album & track, and additionaly replaygain pre-amp. So one has to turn these off on the standard playback options, as the 'effect' is already being applied by the input plugin.

I've set the upsampling to 24 bits & 96khz (highest quality conversion), the highest my card will support, along with Album ReplayGain and +3db ReplayGain pre-amp to emulate my previous playback settings, and turning off Winamps own Replaygain processing.

There is a definite improvement in sound quality, particularly in the smoothness of the top end, everything seems more controlled (not in a bad way)...I like it :):):)

Not only is it an improvement on the original FLAC, but it is also an improvement on the original CD (which sounds identical to the FLAC). Is it the 24bits or the 96Khz or both? Time for some research ;)

N.B. there is an overall increase of around 10% cpu usage for one stream, so this technique may give rise to a performance issue on the squeezebox server when running multiple clients ;)

Gazjam
11-01-2011, 21:46
Regarding upsampling Flacs to 96khz...

Klaus (Soundcheck) reckons his mods work better with 16/44 "native" rather than with upsampling the Flacs to 96khz...
Will try that one tommorow.

Interesting...

Yes very...it's certainly noticeable through my soundcard from winamp @ 4608KBPS!!!!:)

I doubt I'll bother with SoX on my SB server as it won't have the grunt...

However I am going to try some dBpoweramp .wav upsamples (I wonder how the upsampling algorithms compare) on my SB receiver , at least I'll see if the Wolfson DAC really is 24/192. Not a strategy but worth a test ;)

Edit; Neither the receiver or the SB3 will play anything above 48k, unless I've ducked up the conversions... :doh:

Edit; That appears to be their limit due to processing limitations, despite the DAC's capabilities.

Think I'll start a separate thread on upsampling in general...rather than hijacking this one :)

I'm just joining the fray in singing the unreserved praises to this batch of mods. As of last night, I too am the one who took the plunge and applied many of the software mods to the Touch.

The only mod I wasn't able to try out was switching from the wireless to the wired ethernet (reportedly the most important mod of all). Still, with this vital piece of the mod missing, I am happy to report that the other mods made a hell of a positive difference.

I warmly recommend to all Touch owners to go ahead and apply these mods. Actually doing the mods is easy-peasy, there's absolutely nothing to it (even for me, and I'm a certified Luddite and a guy notorious for being allergic to technology).

My main objection was turning off the screen on the player; however, now that I've done it, and in hindsight, I kind of feel that the screen was a bit tacky and cheesy. Since I'm using the remote anyway, I really don't need it at all.

So now it's all about the sound quality. And my god, the improvements in that compartment are nothing short of breathtaking! On tracks where I thought I've heard it absolutely all, I'm now hearing brand new details in crystal clear clarity. I'm not going to say that now everything feels much louder, but it does indeed feel much more PRESENT.

I can't wait to get to the point where I can apply the WLAN mods, as these are supposed to really open the player up (apparently the wifi module in the player is the biggest culprit in introducing the noise and other disturbances; obviously, getting rid of as much noise as possible allows the music to bubble up to the surface in its full glory).

Anyway, see fer yerselves, you won't look back after you apply this super easy, 10 minute walk through a very straightforward menu that Klaus so generously prepared for the community.

I've installed the previous mods Soundcheck put on his Blocg and can say they make a good improvement.

The second version of his mods look even better...

Soundcheck is at it again, this time offering the biggest bang for the buck. Over the weekend he had just unveiled his touchtoolbox20BB1, which purports to fix the volume at 100%, and KEEP IT FIXED.

You can read more on his blog: http://soundcheck-audio.blogspot.com/2011/01/soundchecks-tt-beta-blog.html

To my ears, this mod, of all his other mods, makes the most dramatic improvement in the sound quality. Going back to the non-fixed volume, after experiencing this fix, reveals how soft and wobbly the signal is when not truly fixed (even when forced to be at 100% loudness).

That's not to say that some people will not prefer the soft and wobbly sound. YMMV.
