Class D, really? I suppose in the modern unsustainable consumer disposable society they may be relevant and sound ok. The question I pose is, will they be durable and serviceable in 20+ years or just another contribution to electronic waste ? I say this listening to a 30 + year old jfet cascode afe and mosfet ops Hafler 9500. This amp was restored to perfection by myself with all the best components (Audio Note, Mundorf, Dale , Exicon, Cardas, Sparko Labs front end power supply, etc..). Still believe super fast switching will never beat no switching. And tend to believe too much switching is detrimental to ones health. it could possibly be why analog audio is so meditative for me.... Ok thanks for reading my rant about class D. To be honest l, just don't understand class D schematics and topology. I do understand that most here are not builders, but please to those who are not, consider that your choice will limit the supply of anything worth keeping out of the landfill in the future..
Class D for Repatriated Merlin TSM MMI
I recently repatriated a pair of Merlin TWM MMI from Singapore. Calvin Ho of CK Audio made its return home quick and painless.
I have read the forums and understand that most seem to prefer tube amps. I know that is is against convention so far as I've read, but, due to heat, space, my back and weight, I am inquiring of any successful synergistic pairing of Class D amps. (Yes, I am trying to avoid 55 pounds of iron)
My sense are these little guys might benefit from lots of power but like everything the proof and synergy is in the pudding.
Thanks for any experience one can share.

@atmasphere , Thanks for your post, you make some excellent points! I do understand that the different harmonics of distortion are what gives amps their sound etc and I'm sure these modern machine built products sound fantastic. For me, it is about sustainability and being able to fix my own gear. I suppose you could be correct about future serviceability. It seems in the realm of possibility that a machine similar to the ones that build the smd boards, could troubleshoot and rework them. For now it seems mostly that only the factory will service smd boards and after warranty expires well... For myself, my hands are too big and my eyesight is not good enough to want to go near one of those boards... as I suspect are many techs, so sure just replace the module, but what happens to the old module? I replaced a hypex PS module once and the boys from the Netherlands didn't care to take the core. I do admit that I'm a bit of a retro grouch though. Peace |
