I've got around 150 hours on my Red Wine Audio Signature 70s. I put on Rossini's "Italien in Algiers" the other night. That opera has never really tripped my trigger all that much, but the other night it blew me away. I never really noticed how great it [that opera] is until hearing it with my new amps. This can't be attributed to detecting new music details not previously noticed. It has to be more like a qualitative leap. A difference in kind and not a difference in scale, though there is that as well.
Rather than carry on trying to find new words to report my findings, I scoured the archives here and these are some of the comments that brought me to the purchase.
I think you have just created a Solid State SET
You mean to tell me that this is going to get better?? Wow, that seems so hard to believe since there is so little to complain about now.
They sounded great right out of the box but what I am listening to now is sound in a different realm.
I can't help but be drawn into the listening room by some musical phrase that just sounds stunning and demands my attention. these are truly the real deal!
"These really are the shit, aren't they?" It wasn't really a question.
It's pure magic, "involving" and "musical" in a way that lets the music draw me into a sort of trancelike state where everything else just kind of drifts away.
The Sig 70s have some serious drive. I am hearing better bass than I have ever heard in my room with a variety of amps, pre-amps, speakers.
I cannot imagine at this point, a better sound in my home than this amplifier lighting up the B202 on OB. [This one was a Sig 30]
I cannot take the Signature 30 out of the system...it is addicting...seductive...
beguiling...fantastic...
the Signature 30 gets out of the way...there is no amp
there...only...MUSIC...THROBBING...PULS ATING...in a thoroughly NATURAL
presentation...
there is no disconnect in refinement shifting gears between the Signature 30 and the other amps, Music Reference 45 in Richard's case, and Korneff 45 in mine. That this thing can hang with those amplifiers right out of the box should tell you something, and the 45 tube is well known as audio crack, it is that addictive
Folks, this amp is green and is therefore at its worst right now. At its absolute worst, as new, it is beginning to astound me completely. [Sig 30]
suffice it to say that this thing really is special. My only amplifier is a SET PX-25, and so my ears are tuned in to the big triode sound, and I can only say that my ears suffered no real tube withdrawal with this digital amp. I don't even want to say it mimics a tube amp because to me at least, it has its very own sound, an open and bottomless sound, like this abyss, created by (I suppose) the otherworldly low noise levels, do something that affects the psychoacoustic interpretation of the music.[Sig 30]
This amp has no trouble at all driving my VMPS RM40s. Overall, if I had to put down some of my own adjectives, they would be - huge, deep, powerful, fast, clear, nimble.
So, I answer my own question, "Are the Signature - 70 Monoblocks any good?" in the resounding affirmative.
