The REF-3 is also tube rectified by a 5AR4/GZ-34 I believe.
Guys-Thanks for all the kind words on my decision to purchase the VS115. I did jot some notes down on the first night of listening which were all positive, but I want to spend more time with this amp before I make any statements about how it sounds. Not only am I listening to a new amp, I’m listening to a new output tube (the KT-120) which I have never heard before either. I will tell you that I’m happy with my decision so far.
I do know that the Krell KBL preamp is not the right match for this amp and I’m hindering its ultimate performance by using it. The balanced input impedance of the VS115 is very high at 300K. The KBL is not a high gain preamp. With other amps though, I never had to turn the volume knob much past 9:00 to get the volume level I like. Not so with the ARC VS115 running in balanced mode with the KBL. I have to turn the volume up to around 12:00 to get the same level which is highly unusual in my room.
The good news is the amp is dead quiet as I expected it would be. And after the Krell KSA-250 fiasco, that is quite a relief. As soon as Krell repairs the KSA-250 (or tells me it’s just fine) and the new owner pays me, I will start looking around for a tube preamp to mate up with the VS115. I want to do better than the LS-17 that I owned before (and right now wish I had back) though my opinion of it might change drastically when mated to the VS115.
I do think the VS115 is a very cool looking amp. It looks better in life than it does in the pictures. I did buy this amp used on Audiogon, but I couldn’t be happier with the condition of the amp. It looks like new to me. I did call ARC and have them send me the non-conductive bias adjustment tool.
What's this world coming to when a tube amplifier is quieter than a ss amplifier?
micro-I pretty damn sure the REF-3 uses a GZ-34 as a rectifier. It is a rectifier! So even though at the risk of making all of their REF-3 owners mad and telling the world that the the LS27 sounds better than the REF-3, you still think the REF-3 would be the better sounding preamp?
Isn't ARC's duty to sell new product? Call me skeptical!
Glad to read that the ARC VS115 has solved your noise issues.
I've been looking for a tube preamp, other than the ARC units here's my short list:
Aesthetix Calypso/Calypso Signature
Modwright LS-36.5
Wavestream Kinetics LSx
TRL Dude
Of course it's their duty. However, ARC risked upsetting a bunch of REF-3 owners who have been through the REF-3 update mill and who have all paid really good money only to introduce a new line stage that is cheaper and say it's better in "virtually" every way than the REF-3. You dig?
No, they get ref 3 owners to go ref 5. Or whatever non ending series of upgrades they release every 3 years.
What about the mini-GAT?
