Parallel Zens

[ding]

What is the effect of running 2 ZEN amplifiers in parallel into an 8 Ohm load? If they are 2 10W amps do you get 20W or is this only the case when running them into a 4 Ohm load?

When your speakers are 8Ohm you still get 10W.
The signal is coded as voltage. Higher voltage
swing requires more current (use Ohm's law).
If your amp can deliver the current it is fine,
if not the signal get distorted.
If you use 4Ohm speakers you should get more power
with 2 zens in parallel (4Ohm speakers require twice
as much current for the same voltage). One zen
could get problems with it but with two you should be
ok.
If you use 2 zens with 8ohm speakers you
still get something in return, namely,
lower distortion.

Super-symmetry??

I do not know if the Zen runs on a a + and - voltage rail. If it does: in stead of running them in parallel you could opt for suppying one part with the 'opposite' input. Attach the speaker to both "+" terminals and you acquire part of the 'super-symmetry' which is a feature of the X- series...
That increases the voltage-swing over the speaker.
