Well, this beauty also works with 38v DC linear PSU with the same polarity as original, and no more than 38v DC, the sounds is even warmer and also slightly more detail and less grain, I love it!!! Same linear PSU which mysteriously didn't worked with Topping B100's (exactly same voltaje, same...

Promitheus TVC preamp more info in other forums like this https://www.audiocircle.com/index.php?topic=31621.0

subjetively in my case yes, but yeah is not lab proof statement but for my ears, class D/B with external smps PSU sounds WAY warmer and not listening fatigue than purifi/hypex with internal hypex smps psu

Well the best thing I can say for Topping ABOUT AMPLIFIERS is that Topping DAC is my favorite DAC everyday DAC since years ago. Full doc :) Topping for high end DAC, yes in DAC they are sota ... And no fault with my old E50 or new d50iii yet...hand on wood 3e-Audio for high end power amps or...

I will try to see if it works for me to make this absolutely great otherwise power amplifier with high end external PSU works also at "really late night volume" thank you so much!!

I got your 3e 5A power amplifier at home days ago it sounds great with my Dynaudio speakers!!! Very detailed and with drive control over woofer, no fatigue, so good!And it has all the things I love most in amplifier: -->Really low distortion and noise course. -->Bypassable volume control (if...

Thank Amirm for has the passion enough to measure great THD afordable DAC , power amps (or integrated with bypassable volume control) and loudspeakers minimum impedance/sensitivity. Thanks to your great job at audiosciencereview doc com we now can have a really high resolution audio at home...

Great review and measurements as always, i like the , beside needed usb audio input, the hdmi audio input too, wish my topping dacs got it hehhehe

Thank you so much for review great latest developents in afordable low distortion power amps, dacs and speakers. Whis some day somebody measures also the noise level actual of entry level video proyectors. Regarding this power amp with volume control, love the fact is has a bypassable volume...

Not and yes. Never connect, as others replied you here, a passive loudspeaker to a line livel active output device as dac, active preamp solid state , or any device with straight transistor op amps at line level output. Unless (you are as crazy as me) you make 100% SURE is a transformed coupled...

Oh! So an all discreet output Hypex/Purifi/Benchmark amp is not more robust and reliable regarding low impedances or even power surges than a chip-amp like Tripath or Texas Instrumments based projects? :) fascinating Said that, contradictorily, im super happy with my, reviewed here, 3e Audio...

Great i saw in AliExpress https://es.aliexpress.com/item/1005007964184254.html looking forward measurements here im super Happy with my 3e-Audio tpa3255 PFFB stereo DIY module (150€) reviewed here 102 SINAD i asebled to a linear psu and box... If this measures even better and is same flexible...

Actually the idea is a "error feedback" (in this case not the output thd but customer experience feedback hehehe) so manufacturer in next version of this, again i think is a great product, can enhance the lowest output impedance of power amp so the amplifier would be ...durable and reliable as a...

HEHEHEH thank you for posting actually is very interesting would be great to have more HD pics internals and better a teAR down but perhaps manufacturer doesnt allow.... any way this picture, im not engineer or technician but yeah heheheh it doesnt look very "100% discreet amp" right ? happy new...

Thank you so much for reasonable normal response, obviously ASR reputation cant be better is the only one true INDEPENDENT measuring lab on world. Reputation is the manufacturer that obviously her reability could be way improvable heheheh

Mine are Triangle Borea 07 with the followed manufacturer specs, and the one Amirm measured here Borea 03 or 02 cant remember exactly but what i remember exactly is the measured miniumum impedance by amirm was same figure exactly as stated in manufacturer specs of that model so this...

Well hehehe is a Teradak is a popular Asian linear power supply for DACs, that is r-core transformer... 5v, pair great with Topping E50. Is better that directly the fanless PC USB volts also silver the other side of furniture? Perhaps not but I like linear PSU. I known nothing says it measures...

Well the manufacturer says minimum impedance of Borea 07 is 5 ohm and @amirm measured other Triangle Borea and happened that manufacturer didn't lie in other model with minimum impedance so that's why I ordered it on France on home cinema solution and everything was great, I wanted a tower with...

I had had , yeah what a casualty, nc252mp stereo built from audiophonics, it's more reliable because is hypex, real discreet, more powerful but not as detailed and high resolution as b100 but much more reliable. I sold mine because I'm addicted to detail and it was not enough for me, is like...

B100 fully discreet with firmware and USB-c port? C'mon! You got it also, and you know real discreet hypex UCD won't blew up as this did...in web or even audiophonics site never manufacturer states B100 is discreet and being class B it could but I guess perhaps all that 3 layers feedback is...
