It started with the power supply being removed and replaced on a fitted bed of Dynomat Extream,and mounted on bushings.
Then the refitting the PSU with 2 huge JJ caps the rest are Audio Note Kasi .Elna Silnic 2 where not in the path.
Wire wound resistors Ayden Q cap and big Shockty diode and a better ON power regulator transistor.
All the resisters in the amplifier section are nude Z foil and Caddocks, all capacitors in the path have been way upgraded.
Also Audio Note tube sockets and RCA Jack's and the Digital SPIDF is a Canary 75 ohm BNC.
Internal wire is DHLabs silver wire.
P.S. Audio power cord, and vibration dampening feet.
Everything you can do to this DAC has been done and initial impressions are stellar.
More to come I am at 45 hours burn in.
The first thing I noticed is how quoit it is now, no noise floor,solid state like black back ground .
So far is is way more dynamic, bigger sounding over all and very smooth no grain what so ever.
I will start tube rolling after 200 hours ,the tubes in it now are new tungsol gold pins. The bottom plate had to be raised on pillers to accommodate the big JJ PSU caps. This was a huge undertaking in parts sourcing. It involved a lot of research and weeks spent waiting on special ordered parts.
The biggest credit goes to Paul Warenycia who was able to de solder / solder it all with out lifting a trace and fit it all back together looking neat and clean!

Like I said it was a big team effort that took months to implement correctly this one of a kind ,my take on what the SE version of this DAC would be.
