No, can’t see what you’re getting at here, but you do seem to have a few loose screws...:lol:Quote:

Whoa..
using the Oppo 203 as a Roon endpoint (digital output to my Dac) and after fitting the linear power supply i’m like.....
Yeah, ok..enough.
Night and day better playing Flac into my dac, this is tremendous.
as always...nothings blown up yet!Quote:

Read up on the guy in DIYAudio and elsewhere, the seller knows his onions and his products are well thought of.
I've ordered the Furutech/Mundorf wiring IEC upgrade too, from here:

What about the 'after' picture then Gaz ;)
Some hours now on the power supply and things are improving as components start to bed in.
Nice.
Hey Tim, hows life treatin' you? :)Quote:

Comparison between stock switcher and linear:
http://www.jasonmyres.com/external_f...DP-203_PSU.jpg
Oppomod does two linear psu's, I went for the SE version, which has better spec'd components.
Blurb from his website:
"The highest audio grade low ESR Nichicon KW series electrolytic capacitors are used.
Multiple all discrete Schottky barrier diodes are now used throughout. The lower voltage drop of the diodes provides higher switching speed and better system efficiency, while producing less heat, EMI and switching noise.
Wima film and tantalum capacitors are included for regulator IC buffering and impendence matching. Audio grade AMR 2A gold fuse is included."
I'll be swapping out the fuse for something better, I'm funny that way...
ye just cant leave things alone!!!
That Dunkirk spitfire will no doubt sound rather splendid -and not look too shabby either!
Pretty good Gaz, fully retired now which I have to say I'm really enjoying - plenty of time to really indulge my passion. I'd like to read more, but can't stop playing music! How did I ever find the time to go to work?Quote:

Like what you've done to the Oppo too.
Yes, the power supply is the same one I saw on ebay. What mains cable are you using Gaz?Quote:

The cable Ive used throughout is 4mm solid core french spur cable, thick as yer wrist and just as difficult to bend round corners.
Marco recommended it as he uses it and picked it up for me at the time.
The Oppo responds well to mains supply improvements, the silver wired Furutech IEC socket and the new Synergystic Research Blue fuse that are on their way should give similar improvements to fitting the Oppo with a linear supply.
Never seen picture quality like this in my puff, and it’ll get even better.
I’ve decided to stop here and not bother with upgrading the clock, maybe look at damping the chassis with deadsheet and get better isolation feet for it, and call the movie watching kit done.
Maybe that’ll improve disc playback, has done with any CD player Ive did it to.
Excellent stuff mate, being but a mere slip of a boy I’m way too young to retire....ish. :)Quote:

More goodies to come with the Oppo, enjoying the journey.
At just 59 I still think I'm a mere slip of a boy . . . in my head anyway!Quote:

AMR Gold fuse prefitted to power supply and the new SR Blue. Some blurb that came in the box. Have the SR Blacks in my system and they were a bit all over the place until they settled down.
https://i.imgur.com/Kjfrkux.jpg
Fuse fitted and ready to screw the lid back.
https://i.imgur.com/96T74IT.jpg
Straight from switching back on the picture was noticably brighter, sharper and colours popped with greater contrast.
I need to adjust the tv picture settings again.
Crikey. :eek:
Watched the latest episode of Star Trek Discovery in 4K HDR on Netflix, blown away by the picture improvement.
Looked ‘real’, different uniform textures...light catching strands of hair...pores in skin, all that stuff just drew your eyes in.
Most surprising change was the sound?
Last few days Ive been playing music through the TV as one of my 300B valves went pop and Im waiting replacement.
Sound quality pretty good through Sony TV panel, could live with it easily for a while.
After fitting the new fuse the bass was much deeper, punchier and tighter...from the tv.
Music sounded noticably better.
Guess Im making more of the linear psu now, of course caps n stuff will need to burn in as will(disbelievers look away now) the SR fuse. :)
Still the Furutech/ Mundorf silver wire IEC to fit when that comes, should be another step in eliminating any mains bottlenecks in the Oppo and letting it really do its thing.
Superb bit of kit this, look forward to hear how it plays as a CD transport and Roon endpoint after all the mods are done and bedded in.
Sounds pretty great as is just through the telly, look forward to it strutting its stuff when my system is back up and running with the New 300Bs.
*EDIT*
Musics on in the background, soundstage is much wider than before, more detail, more natural and less shut in sounding, I like this!
looks like your in for a treat when its all up and running
Thinking of damping the chassis, Grant you remember that link for the deshete stuff you posted before?
Will have a look when at pc. Lying down at moment mate [emoji3]
Take it easy mate, I'll have a look. :)
Thanks Grant.
Ordered some of the Silent Coat to further deaden the casework, last thing is better isolation feet then I'll call it done.
Any suggestions chaps?
*EDIT*
I'll start a separate thread for this.
Feet sorted, set of Sound Damped Steel plates.
http://soundeck.bigcartel.com/produc...ss-steel-black
Work well on glass table under my turntable, improved the Oppo too when I tried them.
https://images.bigcartel.com/product...&h=1000&w=1000
Last things to do are line case with dynamat sheet and fit the Furutech/Mundorf silver wire IEC inlet.
Job done. :thumbsup:
That will perform with amazing results with those upgrades.
I'm using a Furutech Alpha 3 cable with the Furutech plug and carbon fibre iec into my Onkyo SR605, fitted with an SR mains fuse. The effects were as you described, deeper tighter bass and a much bigger soundstage. I made the mistake of taking this cable off the hifi
as a mere experiment and the improvement was so great I had to go out and buy another cable.
I'm also using a neotech cable on the ps3 fitted with a better fuse. The result was a brighter clearer picture with better colour and detail.
The humax box showed similar upgrades with a cheaper Furutech cable and upgraded fuse.
All my A/V system is fed via a Belkin pf40 which was the first upgrade to sound and picture on the AV system.
Gaz
Fascinating. Which Oppo unit did you start with? I have one Oppo DVD/SACD player, but it's old by modern standards.
Hi Dave
Its the new 4K one, the 203.
Feed the Blurays audio into my Dac, so the better analogue board on the 205 would have been wasted on me.
Strictly for video, that said these mods Im doing is really making improvements to audio, really surprised actually.
Looking ahead maybe something major in the works for it?
The guy who delveloped the linear power supply has designed an output board for the 203 which outputs i2s over HDMI.
Interesting to me because my Dac has an i2s input as its best sounding connection.
As the Oppo can be used as a Roon endpoint I could also send music from Roon through i2s, which should be interesting!
Even if musics bettered from another source, movie watching through i2s to the Dac will be great.
Suspect the output board will be as good as his power supply, a no brainer for me really, but one for the future though as the boards not ready yet.

To quote Wiki .....
Cables need to be really, really short.Quote:
Limitations
The I2S connection was not intended to be used via cables, and most integrated circuits will not have the correct impedance for coaxial cables.
I hear ya Chris,
Still have the Young but its not in the main system anymore.
new Dacs got some different inputs...
https://i.imgur.com/fxGtmV1.jpg
It looks like cable interfacing and impedance is sorted, Gaz.
Just keep the cable as short as possible, and the shorter the better.
Yup,Quote:

Decided to put some vibration deadening material on the chassis? Started with the Transport itself?
https://i.imgur.com/nb6zCcn.jpg
Given I'd put a linear PSU in there, better check for height clearance...
Looks a bit high...
https://i.imgur.com/LiblFDX.jpg
Thinking about putting damping material (which is 4m thick) on the Transport AND the underside of the lid, best to check for clearance...
Yup, cant put damping material on both the transport and the underside of the case lid, need to cut out where it doubles up...
While I was working that out, the bits of the internal PCB that I couldn't access I damped from the other side...the bottom of the chassis, making sure the ventilation holes weren't coverered.
https://i.imgur.com/e25FFGn.jpg
All that exposed aluminium foil I wasnt happy with...ok for the underside but not internally (RFI/EMF...dunno?) so decided to cover the damping material in electrical tape, isolating any potential...whatever?
