Hi, what further kind of tests do you want? Based on my subsequent tests, this power supply does not add artifacts on FFT compared to others SMPS that I've tested (as good as LRS-350 series).Hello Lester

Tazio,Hello guys.
I'm a beginner trying to learn and maybe the question is silly...but ...am I wrong or there's no volume control?
Anyone minds posting the wiring diagram?
Thank you for your interesting explanation. Really appreciated.Tazio,
Good question.
You normally connect an amp like this to a preamp or DAC and feed your audio source (like a streamer, tuner, phono, phone, etc.) into to the preamp.
I use Topping E 70 as a preamp for my amp setup.
Topping E70 Stereo DAC Review
This is a review and detailed measurements of the Topping E70 stereo USB DAC with Bluetooth. It was sent to me by the company and costs US $349. I really like the new white multi-segment display with its large volume level indicator. Response is excellent as you rotate the encoder. A select...www.audiosciencereview.com
Some amplifiers use the same amplifier chip (the TPA3255 from Texas Instruments) and provide a volume knob. An example would be an Aiyima A07.
This amp has a couple of integrated circuits called op amps built in that act as preamps,
Aiyima A07 Pro Amplifier Review
This is a review and detailed measurements of the AIYIMA A07 Pro stereo amplifier. It was kindly drop shipped to me by a member and costs about $90. As you see the distinguishing factor from some of the other Aiyima amplifiers is inclusion of tone controls. Alas, that is also where the problem...www.audiosciencereview.com
Thank you for your interesting explanation. Really appreciated.
Though, if I want to couple the Sylph D200 to a turntable featuring a built-in pre amp, would it be possible to simply put an attenuator on the line in?
Looks like others have different opinion ...I’m fairly certain it won’t work without some type of preamp in front of it.
Here‘s my friendly advice: buy an Aiyima A07 or Fosi V3 (both for under $100 from Amazon) and start your TPA 3255 amp journey There. Both are great sounding, affordable amps will save you money and frustration.
In my opinion, trying to build a DYI amp from a Sylph module is not the place to start and will likely prove to be the more frustrating and far more expensive way to go. Make the Sylph a second or third project if you still care to.
My bad: it does appear to have the op amps on board.Looks like others have different opinion ...
Buying a finished amp is not DIY. I want to challenge myself and try to realize something on my own ...thought that assembling a couple of boards and bunch of components isn't transcendental.
