Marantz uses class D in all of their highest end amplifiers now. One for instance would me the Ruby integrated, another would be the PM10, etc...
High end Class D amps?
Just an observation and a question. Are there 'high end' Class D amps out there that are just as good as Class A, A/B amps? I realize that's a sensitive question to some and I mean no disrespect---but whenever I see others' hifi systems on social media, all of the amps are A or A/B. There's always Pass, McIntosh, Moon, Luxman, Accuphase, etc. Where are the Class Ds? For folks out there that want more power for less efficient speakers and can't afford the uber expensive Class As, A/Bs, what is there to choose from that's close to those brands? Thanks

Yes, but none yet "so far" that have taken the full major advantage of the 1.5mhz switching speed on offer when GaN Technology is used, that Technics does with the 188lb SE-R1 that also uses linear power supplies, input ones are regulated. https://ibb.co/S6CFz5y https://ibb.co/wwH0vNr Here’s a little to read on the GaN transistor and it’s higher switching speed ability, that Technics have used. https://www.psemi.com/newsroom/pres...fastest-switching-speeds-to-gan-class-d-audio Cheers George |
So....I think I'll buy a VTV Purifi. I suspect I'm heading for disappointment again, but there's a 30-day trial so why not? Maybe I'll be wrong this time and I can convert over to class D. I have an all-tube preamp currently. I assume the tube buffer option isn't worth it but what about those op-amps? If all they do is impart color than I can rely on my pre. Is the custom input board worth it? |
I think the Weiss op amps could be worth a try. From what I've read, these are the best discrete op amps available and have the ability to bias the output stage fairly high (adjustable with a small trim pot). I plan to use these on one of the input board designs I will build for my DIY amps. My experience with the Sparkos op amps is that they dulled the sound a bit to much, although did add a bit of welcome body (this was on a hypex amp). The Sonic imagery op amps were very clean sounding but sounded a bit thin and sterile in my system. |
