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

Amps based on the PuriFi modules have received glowing reviews. One example is the NAD M33. There also are some small shops assembling amps from PuriFi and other components. Nord and Apollon are two. I'm pretty sure that 6Moons really liked the PuriFi demonstrator amp. I find it difficult to follow their reviews, between gobbledygook, constant reference to products I don't know, and tiny paragraphs of text sandwiched between huge ads. |
There is only one so far that has taken Class-D and it’s operation to the technology edge, that "could" even better the best Class-A or A/B’s. And that is the Technics SE-R1 that uses linear power supplies, the latest GaN devices, and has taken their "switching frequency" nearly 3 x higher than any other Class-D’s have so far, which means 3 x far less switching frequency residual noise and all important phase shift at the speaker terminal outputs. This 55kg monster has taken Class-D technology to the limit "for now." https://www.stereophile.com/images/styles/600_wide/public/010517-Technics%20SE-R1-600.jpg https://cdn.shopify.com/s/files/1/0258/1705/5311/products/parts_image_540x.jpg?v=1586671330 https://www.technics.com/us/products/r1/se-r1.html Cheers George |
