Hello All
I have now finished my pair of Pass ACA Amps and am extremely happy with the result. My intention was to use them as Monoblocks. ( Not sure really why !)
I am playing around with the Mono Bridged and Mono Parallel Modes. I believe I have this right :
Bridged Mono - I get an increase in output voltage (x2) and potentially a x 4 increase in power ( knowing there are some losses) - Basically louder !
Parallel Mono - No increase in Voltage / Power (??) and each amplifier is driving each speaker.
I am using the Korg Nutube B1 Pre-amp with an old iPod as input and a pair of JBL ok speakers - Al sound pretty good !! , However Bridged Mono louder.
Is there any sonic improvement of one Mode over the other. Is there a longevity on the amps of one mode over the other ??
This has been a very rewarding project !
Cheers and thanks for your input

The sonic improvement is for you to determine for yourself by listening.
We can not tell you which will be best with your speakers.
Deciding which way is best is the fun part of DIY. You get to listen to lots of music.

I havent tested ACA bridged, but stereo and parallel mono.
And in my system - going from 1 stereo ACA to twin parallel mono amps the difference is: The same sonic signature as in one stereo, but the parallel mono amps gives the feeling of an even more juicy, firm and powerful bass, with the same awesome overall clarity and resolve, at a even higher volume.
