Rythmik Sub Mods

jtwrace · 16th November 2007, 12:05 AM

Has anyone ever upgraded the caps or any internal parts? If so, what were the sonic gains/cost and what parts did you use? I've been thinking of doing some Black Gate cap upgrades but have gotten some very mixed feedback. Any help is greatly appreciated.

Thanks-

sonic gain in subs ... you must be a joking

Seriously, I wouldnt mess with that rythmik amp, unless you are VERY skilled and know exactly what you are doing, and in that case you wouldnt need to ask

Subwoofer usually output well over 10% THD at reference levels.

You are way better upgrading to a better subwoofer driver.

Rythmik already sell improved amplifiers. I bet you could ask them and they could tell you what can be improved.

I purchased an amplifier from them in the past and they were always helpful.

I think upgrading op-amps and adding more power supply caps may be better than changing them, but I dunno...

Good luck !

The only thing I'd want to change is the transformer, standard one on mine hums quite a bit
