anyone familiar with the sound of this amplifier RH-307a?
The RH Amplifiers is a snippety subject. For what they meant to be they are reasonable design avoiding large cap in feedback and in particularly of you have no good OPT where grounding of secondary raises your parallel losses. The main question I would ask: why? If you use some kind 1000W plate dissipation tube then use of pentode is understood: you need gain and power. But if you at 106bB sensitivity then why would you need to worry about all those feedbacks and how to apply them if a regular triode would give all of it without all of this superfluous acrobatics? The answer might be that it has some sonic merit. It might be or not might be. I had a vey brief contact with the guy behind the RH Amplifiers at one of the forums and I got impression that he absolutely uninformed about larger picture. He sounded like a solid circuitry collaborator but absolutely clueless about Sound and what this “hobby” all about. There are plenty of them at all imaginable DIY audio websites, my attitude is that they are good because they solder instead of drinking or shooting cocaine but that is about all why I value them. Anyhow, it is hard to estimate how the RH Amplifiers might sound. They are fine technically, so any other amp in “Best Buy”. Am amp is a sonic expression and the only expression that I heard from that Alex Kitic was that he knew the Ohm Law and that he called me Ukrainian. Anybody who call me Ukrainian is an idiot in my book.
