@3eaudio Could you tell me how many opamps are swappable by the openings under the units with the A7 mono? One or two like the stereo A7 ? Also It's a little bit confusing, I on't understand this in the user guide, if I use some OPA1612 that are ±2.25V to ±18V do I have to change the J30...

So for low volume listening A5 would be a better choice I guess to avoid the stand by mode when listening

Hahaha you should measure it maybe? No Idea what the result could be. They sound better than anything I Heard before and I have a bunch of opamps here. I was more than sceptical but they are return free for 30 days so I tried and they will stay here My goal is not to create a controversy, I...

@3eaudio Are those specs opamps compatible with some of your amplifiers line? Bipolar Input Operational Amplifier Ultralow Distortion: 0.000015% at 1 kHz High Slew Rate: 27 V/μs Voltage supply +- 5V to +-18V Work Temperature - 70*C Thanks a lot

@3eaudio you wrote that the TPA3251 is superior to TPA3255 but TPA3251 is less powerful and produces more heat. So I gues that if I don't need as much power it's better to choose the A5 stereo amplifier versus two mono A7? On the board you published you rate them 5 stars for the sound quality...

What I wish is PFFB, mono mode to use is as monobloc and volume bypass switch

I can't wait for the A7 mono to replace m'y Aiyimas 07 Max, i Hope the Akliam LC5 opamps will fit inside the opening you planned on the top off the cases to access the opamps without the need to remove the case, if this opening isn't large enough i will use wired dip8 socket extenders. These...

Hello, i need a new DAC now and have absolutely no interest in other features like screen, remote, headphone amp etc... there is a lot of DACs that measure excellently on the market, so what would be the best option for pure DAC sound performance ? This Khadas tone 2 pro module with linear power...

Hard to live time for people who listen to components. I suggest you to learn music listening a few days waiting that your already obsolete device arrive
