I absolutely love the "warnings" listed on the PSU (see Post 17, first photo).
Nice warning, that the PSU will not cause harmful interference, I guess.
The second warning, I can't even begin to decipher......!
The unit will not interfere with other electronic components, but other compononents can interfere with it. In other words, it can pickup interference.
I think this is just a case of word choice by someone with English as a second language.

......It's the best Headphone Amp / Preamp, can drive anything, is completely silent, and is just a truly amazing project. On top of that it's utterly fantastic value for the money.
Wholeheartedly recommended to anybody who needs any of the following -
Attenuation
Gain
The ability to drive anything
Headphone amp
Impedance matching
A new, fun, useful project.
+1
I got the new Subbu DAC, the 02 as pre and a BA-3 all together today - and the combo is really top shelf. The ACAs are next to hear with the 02 and I'm sure that will provide the same performance level bump.
I ordered the kit to power my tweeters. The build guide was excellent. Thank you! Very Very simple build, dive in the water is great. I recommend this for everyone. Even if you have zero knowledge. I found the 2.1K resistors finally in the bag with the LCD holders. I now believe the heat sinks I am using for other Pass amps are over sized. This thing gets pretty warm. I am a fan of, if you can't cuddle with it it is too hot.
I just finished mine, adjusted the bias and now am listening to them through my fairly inefficient speakers. I was surprised how much I had to crank up my preamp compared to my Aragon 4004 Mk II since I don't listen to them loudly. The tonal balance is a little different but they sound ok.
