I finally got around to setting up my RP010B and I am mightily impressed. I just sat down to do some evaluation with a stack
of CDs and I could not stop listening. It may sound like faint praise, but after years of amp/phone combos with "issues",
there are really none here. And I was just listening to some old Time/Life early 80s CDs that are so-so recordings.
Pace and timing, smooth rounded vocals, very nice extended but pristine, shimmering, natural highs.
The nice thing is that the amp is revealing but not abusive. It is revealing in that you can hear the quality AND imperfections of the recording (like some grain in 80's vocals from, say, Foreigner or Hall+Oates), but the amp somehow transforms it into something
sweet. I just felt a kind of sheer joy with this amp. My previous solid state amp was a 2004-updated 1999 Headroom Max.
I also have an RSA B52 that I also love (and I do think, overall is better with lots of tube-goodness and I thought only tubes were
the way to go), but the Rudistor is very close, and could fool me with a tube-like presentation.
(Tubes have a way of curing the ills of bad recordings without masking the truth, but now I see that solid state can do that
also with the RP010B).
The Rudistor is one of those components that makes just has a soul; it's a real work of art, a classic.
I just kind of lean into the sound. Vocals are real and not mechanical, percussion in fast with perfect decay,
strings are not strident with just the right amount of bite, piano is resonant and not clipped but warm an rich,
horns and woodwinds are airy and full, bass is integrated and controlled and has just the right amount of depth
and is not boomy at all. Like I said, it really sounds tube-like. (The B52, when warmed up, has extra tube goodness,
a kind of rush that is addictive that I love, and it still has the edge here.)
So I thank Rudi (and Ray) for their fine, fine work. I without hesitation think the RP010B is the king of solid-state
and is just plain awesome.
