Dreaming of a DIY 8W Class A amp designed by Nelson Pass?

@grannyring that is true, but we all know what an over designed power supply can do for the sq of an amp ( any product, actually ). @erik_squires , as an individual who has not found Pass to be your cup of tea, I believe this ACA kit will change your mind, at least understand, what Nelson is all about. I say go for it. I am also, apologizing to you, for my recent negativity I have shown you. Your threads are always interesting, and the " meter " one, is hilarious. Always, Enjoy ! MrD.

<< sigh >> I can't tell you guys how sad I am that I actually don't have the time and energy to try this kit.

I built a pair of the current 2.0 version for a bedroom system, substituting Audio Note electrolytic and ClarityCap film coupling caps, Welwyn resistors, and silver wiring throughout.  It's an easy build and a sweet-sounding and resolving amp.  Apart from its power limitation, it acquits itself honorably relative to the XA-160.8 monoblocks in my main system.

I built a stock stereo unit, (except for the wiring) from the very first pre-order batch.  What a fun build and this thing really sounds GREAT...within it's power limitations.

I tried quite a few different speakers with it and you do indeed need to match carefully, but WOW, the ACA is pretty killer with the right speakers.

HIGHLY recommended for the fun of building it and a +1 for the sound!

@erik_squires time should not be an issue, as you can build it at your own pace. But energy.....yes, I understand that very well. At 65, my soldering skills ( eyesight, steady hands, and patience ), are not what they once were. Very different than applying Dynamat around horns and equipment chassis’s, as I still often do, for myself, and clients. I do agree with the above posters, as it is worthwhile to do, " if you can ".....
