Nice, neat and tidy. Can''t quite tell from the photos, but are you using four switching power supplies for the biamped setup? The second to last picture with the white cables looks like something different could have been used.

As I mentioned earlier I considered four Amp Camps with the 200 VA toroid just installed in my build. The modules are small enough to fit all four in one reasonably sized case.

We tried 4 as well as using 2 and splitting between each pair. For me I think the jury was out on the benefits of the extra PSU. The bi-amping was a clear winner though and gave a lot more headroom. With 91db speakers (both small and large) it sounded crystal clear at a healthy listening volume.

Thanks, sounds encouraging. Will get another pair from the next batch and experiment.

zany, "......Separation of instruments and singers was greater, I was made more aware of the surrounding space." That's the same characteristic I thought was so impressive with the larger toriod. Really special for such an uncomplicated design.

Bob, yes, and I am noticing something else... greater sense of timing. On some tracks I'm very familiar with, it seems the ACA has slowed them down as if the rpm dial on a turntable has been turned down... really strange - making me double check that I'm not hallucinating!

Wow, the ACA chassis look amazing! They could also mount a mono chipamp with no difficulties.

That chassis might become a very popular product.

Hahaha, that's why I drive Alfa Romeo, love it!

Beware my Swiss made F5Turbo amp and chassis....I will be posting pictures soon

Maybe I have to apologize for my post#783.

After listening to the ACA #1 being connected to my DIYed desktop - speakers ("Little Susies") for some days now and getting the ACA #1 familiar
with my "Little Susies" and my ears to the sound of the both of them: "both of them are doing a good job".

Best regards - Rudi_Ratlos

Rudi this is good to hear.

I too was not impressed with my 2 min trial connected to one set of my speakers (2 way Warfdale's) but there is so much that can go wrong,
like speaker placement - the room is so important also.

I know the SQ is there because with headphones the ACA is 5 times better than all the other amps I have.
It is so much better.
Thanks

Congo5, Do you have any photos of your setup for the ACAs with earphones? Are you using a balanced set/converter?
