Hello, I was wondering, I just finished up my ACA mini and was going to hook it up when I realized that the regular ACA I build already also has a 24V power supply. Are they just as good as one another? They are obliviously different, but for convienince of swapping out amps here and there is one of the power supplies better than the other, becasue if so I may choose to leave one in there for both amps, if not, well the two will be available. I am tight on plugs and wire space already. Thoughts? Thanks.
I tried switching them after reading that someone earlier in this thread said it sounded better with the power supply for the original ACA amp. I believe the power supply for the original ACA amp has more amperage than that supplied with the Mini kit and the original is obviously larger and heavier, but I'm only a novice. During the switch, I did not notice a huge improvement but admittedly did no critical listening. I'll have to try it again when I have more time.

I’m a little late to the party, but in picture 4434, I don’t see any solder on the ground pins of the input jack. I’m guessing that the other channel is supplying the ground reference.
Thanks for taking a look, JD. The empty holes on picture 4434 are for the plastic guide pins of the input jack. The positive and negative pins are soldered in.
After listening to it all weekend, it sounds amazing. At one point, my wife was inspired to play our piano to the song below. Our piano is located near the stereo and our floorplan is open. I can't say that my stereo setup sounded exactly like our grand piano but it sounds really dang good. We don't hear all the hammers striking with our piano

.Hey @ClaudeG. I am currently running an Intel NUC Roon --> Schiit Bifrost 2/64 --> Whammy --> ACA Mini --> Zu Audio DW Omens. The Whammy currently has two AD797ANZ opamps but normally has a dual Classic Burson V6.
I have a potentiometer coming to allow me to remove the Whammy and put the ACA Mini on top of a little box. I'll post some pictures once it is updated.

Ohh boy. So, here we go. For the record, my first build went great ACA. This one was going great until I was connecting speaker terminals and forgot that it was PLUGGED IN. Something happened, as it was perfectly biased last night awaiting installation to my system today. Did I mention that the switch was ON. I thought I heard a little op, and did smell something electronic as well.
I should have waited for the parts to arrive to build my case.... But I wanted to hear it.
I am getting a small buzz out of my right tweeter, like a pulsing sound. Nothing from the left. Bias ports are in range when its on.. It seems that the power supply is cycling as well as if in protection. Anyone have any thoughts, I know I do hahaha.

Hi Nelson, sorry for the hassle. I just wasn't thinking when I decided I wanted to hear it. So, would I be getting output from the good channel, Because I was not. My right channel was pulsing, and my left is silent. Can you explain to me which resistors and how to swap them? I am preparing my case right now to prevent another issue. Dumb Move.
