Audio gd never use 3 stage step down regulators. Too big.but sound get little better

Studer 900 board more details but little colored vs sigma11. Lt1963 more neutral. For best sound I using both.not so warm, detailed, airy, forward, deep....perfect for me!

How good is your ac line??? If lps1.2 better, your ac line bad.you must be using power regenerator.

option C) -source upgrade -singxer f1+ultra low noise power -lush2 isolation designed short usb,dc cables -power regenerator

Matrix regulators just crap.Better when powering f1 crystek separately,with some 3 stage step down parallel connected ultra low noise regulators like 4xlt3045,hplun or others.

months ago I posted my experience about digital stage power. Voila!!!

0-5.4v 45Farad ,can feed my dac modules,or F1,or some low amperage gadgets.I have 8v version ,can feed my sclk ex clock example.

I don't know digikey, but in china the nesscap very common stuff.from Taobao example.

Now, F1 feed Lps1.2-sps500-500w own isolation transformer.not so cheap option,i know.im just lazy to build one more nesscap psu with relay,(5v 500ma)can beat lps1.2-sps500 combo. ultra low noise linear psu also can be the other option,but because the Ac quality,always degrade the SQ...

Dullest sounding option this!

sold my nos7,new owner step up Ref7 - nos7.very happy with it.

R2R Digital stages, Xilinx,clocks.... feed digital power like ultracapacitor(Lps1.2),or smps(Sps500)Sound not warm!!!! Audio gd power supply great for analog but not for digital! especially the R core transformer,really warm sound vs torroid

Regenerated AC,isolated analog-digital,isolated L-R,high quality clocks,high quality source,dedicated power for all stages,extra short usb cables.......Really Matters!!!

sclk ex clocked singxer, powered sps500(+lt3045), or uptone Lps1.2 the most significant upgrade in my system.
