'Analog Dinosaur' succumbs to the joys of FBA : enter Raspberry Pi 2/IQ-Audio DAC+!!

As regarding Power supplies for the Pi.

I have built a few various linear power supplies with regulators and even pre tracking regulator types but still come back to using the Raspberry Pi designed smps.
This goes against my normal experience but much prefer the sound when using it

Regarding IQAudio Pi-Dac+ volume settings

[NRG]

Hi

Very interesting thread. Forgive me if this has been covered already (I got through 30 pages before composing), but is the emerging view that the pi2+IQ dac would give an SB Touch/Caiman mk1 setup a run for its money (noting that both have longdog linear PSUs and the caiman had a full Jimmy Drips workover)?

If I were tempted to test the water presumably I could turn the Pi into a Squeezeplug and use it just like the Touch (ie stream from the vortexbox and internet using LMS over my wired network).

Would either Longdog Linear work with the pi (I am an electronics numpty)?

Although I've not heard the IQ DAC yet as I'm waiting for stock to come in there is a strong hope that it will outperform the Touch, however, the proof as all was is in the pudding. The Touch is 5v same as the RPi so Nick's lovely PSU's will still work, same amperage rating as well I think.

Squeeze plug runs squeeze lite the audio player and has LMS installed, I've not tried disabling the inbuilt LMS and pointing squeeze lite to my NAS....something to try later.....

Edit: just tried it and yes LMS on my NAS finds the Squeezelite on the RPi....

If you only want to use Squeezelite player, do you have particular reason not to use the picoreplayer?

...none other than stupidity

After 3 or 4 days faffing around with different Squeezeplug distros, and different WiFi dongles, I still failed miserably to connect via WiFi, I could see the WiFi connection IP address, but as soon as the LAN was disconnected the WiFi connection died too...

So I tried PiCorePlayer, like anything Triode's involved with it works well...

Pi 2 + IQaudi DAC+ now installed in the kitchen, and happily running in synchronisation with my Touch & MDAC (living-room), I'll let it burn in and report back...

FYI, I didn't get the Edimax dongle to work even with PiCorePlayer, but have had success with a 'Plugable(Realtec)' one instead...

The RPi seems to be quite fussy over what WiFi dongle it likes!

The angle of the dangle was always critical to the wangle, in many 'applications'.....

I bought a Camac IEEE802.11 for it..

I know, but let's see what Paul Hynes can come up with...

Regarding IQAudio Pi-Dac+ volume settings

Good to know. However, I really can't hear much difference with the Playback Boost disabled or enabled. Can you?

Marco.

[WAD62]

After fannying about with the ALSAMIXER I've now settled on the following settings...

PCM = 100%
Playback = 0%
Boost = 100% (the mini-1 needs a bit of help...perhaps)

...Starting to sound significantly better than the SBTouch/HiFimeDIY U2 combo it replaced

[Marco]

Hi Will,

Interesting... I guess whatever sounds good, sounds good. However, I'd be more inclined to follow the instructions from the manufacturer Dunc posted earlier, which outlines that both Playback and Playback Boost should be set to 100%, and then reduce the PCM level instead.

Btw, did you get the PM I sent (forwarded from Alan S)?

Marco.
