yes, it is so good on certain speakers that even prototypes have an almost too long life ; )
ACA has best "swing/timing" with those cheapos, better than V-Fet. It is long time since I heard an Aleph J, but I recall the trebles with the J not that lively. But could be wrong there.
best,

Nice and clean boxes Stefan. I like the stands too. Did you use any BSC with the aca?
Wow. That’s a fantastic site. Thanks for the pointer.Anyone not familiar with Rod's great site needs to be:

Hey guys,
New to this forum as I just received my ACA 2018 kit today. I was going through the components for the boards, and labeling the color coded resistors, and noted that I have two 33.2K ohm metal-film resistors that appear to be extra. The color code is orange orange red red brown. I've identified and labeled all the other color-coded resistors on the schematic and the components list, but I cannot find a 33.2 K ohm resistor on the schematic or in the list of components. Is it possible these two resistors were added accidentally?
Sorry if this question has come up previously.
Cheers, Stephen aka PC

The 2 x 33.2k resistors go in R13 locations. They replace the original 10k resistor to reduce the LED brightness.

Johnson's Quadratic Law of Design Reviews:
If you present "N" pieces of quantitative data, the audience will demand (N squared) more.
Yes, but will they ask for p-values?
...which curves are which?
lower ones are for more
lower THD for parallel and bridged (last case)
...which curves are which?
Obviously parallel gives lower distortion, and in the case of balanced
vs bridged, the balanced has the lower distortion.
Tony, I remember np asking when someone was going to make an amp worth 4 ACAs per channel. All you have to do is make another chassis with 4 and you win!
i am making one now, 48vdc, 4 smps psu, 4 ACA channels, and based on the data above i will be making it balanced bridged type using XLR's....i may even throw in a tube buffer to give it a tube flavor...
i am using the conrad engineering 35cm heatsinks....will post once set up..

What is the power output of a parallel 24V ACA into 4 ohms?
The power into 4 ohms would be twice that into 8 ohms if you run them in parallel.
Parallel connection only gives you more (double) the available current, the voltage output is still the same.
For example.
1/ 9 volts rms output into 8 ohm is 10.125 watts rms. The load current is 1.125 amp.
2/ 9 volts rms output into 4 ohms is 20.25 watts rms. The load current is 2.250 amp.
