Thanks for the quick reply,I was not looking to modify op-amps i just didn't see one and was curious .
Also in the tech brochure there was no mention.
I might sound naive and or irrelevant but i am not .
Being used to toroids so long for all my amps (DIY or ready made) the little power sps on board seems not enough to drive such a load.
I am not speaking engineer wise just a mention.
Last month i tried an ice power base amplifer (smaller )and was not very happy their sound sounded very artificial.
Currently i use a a pair of DIY self made tripath 2020 base monoblocks (90 watts per channel) and I am very happy with their sound ,they play
better then my Mark Levinson monblocks .
So after reading all the hype about hypex was curious if such a module base amp will be better then my tripaths ?
Why the fixation on opamps? They aren't something you have to have in an amplifier?
I'll bet the power supply is perfectly adequate and correct.
Not surprised you prefer the Tripaths. They are surprisingly hard to beat. I too wonder about the Hypex, and even more so, the Purifi. I expect it is better, but yet to hear it myself.
