@akgwhiz, I own a Rogue Medusa and rolling tubes makes a moderate but noticeable difference in tone, and extension at the extremes, I have a pair of Mazda 12AU7s in mine.
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

Thanks for adding your experiences with D amps, specifically hybrids which hold my interest. I have a Sphinx integrated now and have 2 sets of tubes on the way to roll (including the Mazdas...). One thing I failed to mention, concerning auditions, is that I live in Anchorage AK. There is ONE store in town that has ONE Primaluna amp on the floor. Seattle is over 2000 mi away. Unless Best Buy counts! Sure, some shipping back and forth possible but likely a few hundred $ per pop in the returned case as many vendors treat us as NOT continental USA. Trying real hard to wittle down to a few lines/implementations. So far as I can tell, every line mentioned using tubes is using them as input buffers. Only Rogue is doing (apparently) it different in their TubeD models by putting them "within" the Hypex module. No EE here, but was wondering if thats potentially a sonic step change from their previous buffer input style models like the Sphynx/Paroah. OK, back to the thread. |
Rogue isn’t putting tubes in the Hypex module. Go to their site and look at the inside of the Sphinx, those 2 small boards on the top are the hypex amps the huge board at the bottom with the tubes is theirs. Compare the hypex photos of the inside of the Sphinx to the stock photo at hypex they’re the same ucd 180’s http://www.rogueaudio.com/Images/Sphinx3insidemed.jpg https://www.hypex.nl/product/ucd180-oem/53 Here's the stock hypex module they use in the TubeD thing on a Dragon. http://www.rogueaudio.com/Images/Draginsidemed.jpg https://www.hypex.nl/product/nc500-oem/50 |
