Cary Audio CAD-280SA V12R

I have one and am extremely happy with it. It's got Ruby EL34's and Generex Gold Lions for the front end.  That's the place where tube rolling gets interesting.
I'm an older guitar player and changing input tubes was the way to find how to get an amp to talk.
On the other hand, I just want to hear everything as I imagine the recording attempted to be.
I like the amp enough, I've looked at buying a spare. 

I used to own both amps. I owned the V12i for a short while - one of my first purchases on Audiogon - and traded it in for a new V12R. What I remember most is the beautiful tone and the surprising low end grunt that both amps helped to deliver . I used them with Quad ESL 57, 63, and 988 speakers. I also had Apogee Stages and Magnepan III’s. My favorite pairing was with the ESL-63’s and Stages.

Since you are interested in using the amp with planars, you might be interested to know that for me, the V12R ran out of juice with the Magnepans when played above 80-85db. The amp worked well with the other speakers I had, though.

I ended up selling the V12R because the combination of the V12R and Cary SLP-98 preamp that i had resulted in too much gain. The protection circuit in my ESL-988’s kept kicking in. There was loud tube hiss through the speakers, perhaps because of the stock tubes that I was using, but also because there was too much gain . The combo had limited usable volume range. I sold the V12R, but in hindsight I probably should have tried different tubes and kept the amp. I should have sold the preamp instead.

Another thing, I’m not sure if the V12i and V12R really have balanced circuitry, or if the xlr inputs are just for convenience. I would double check. Oh, and the V12i and V12R get very hot, almost as hot as an OTL amp.

The above qualms aside, if you have the right speakers and preamp with the V12R, I am sure you will be very happy, just as the other posters in this thread have been.

I just got it about an hour ago.  I need the bios meter. That is a mono 1/4 jack? I guess.. I haven't hooked it up yet. Guy was a real nice, hand delivered it and gave me a two week "take it back no questions asked" deal. Brand new set of 12 matched Rubies, and one used set. A few signals to pick from..

IT IS BEAUTIFUL!!! Man oh man, on tiny little ding, I had to really look to see it. and a factory, boo boo behind the Power transformer, little squigle in the paint. Looks like a factory touch up. Good fix who ever did it..

I sold him a Russco broadcast TT, I have 6 or 8 Russco, Two QRKs. He's a Garrard guy, so he jumped on the ol Russco. Side buy side Russco, and a Garrard. Garrard looks little, compared to the Russco
Same design. Guy was looking for one for a while, I had 8. Go figure
I'm a collector of stuff, what can I say.. Garrard Killer, Russco
I love those things washing machine motors fractional HP. Oilers, adj end play on the motor and TT 3/4" spindle, 8-10 lb platter.. 24/7 for 30 years, oil it service it, every 30 days..

Now to bios this puppy, and dig out two quad sets of the Mullards, they were a good EL34 valve.. Came out of my Marantz # 9 or 7s can't remember.. 25 years ago. NOS though.. 

So you pull the tubes leave 2, 4, or 6 per side. then rebios and run on 4, 8 or 12 valves, total. Does something else have to happen, other than that?
I really want to tinker, I really do!!!

I've got a set of cables cooking as I type.

You have bias the tubes differently if you change the number in each channel , Cary was great help in directing me . Good luck .

Do you remember HOW? Cary isn't answering the phone today, go figure.

LOL shoulda' known..

You know, neo 8s Monsoons work very well with, Macs, and VTLs. I run, 3, 4, and 6. RM30, RMx and my DIY use 4. MC240 with good parts, makes them sing. That's about 55 watt per rail.  Stock 43 or 5 watts per. They seem to like AB better than single ended. The 300b was an eye opener though..

A friend brought over a 300b 17.5 wpc. I was stunned at how well they sounded, and no settle time. I listened to that combo for two weeks. Just killer. 17.5 watts, 6 planar...and one true ribbon tweeter per side. Island music, salsa, slow jazz, everything but Yoko Ono sounded great. No Yoko Ono. LOL

Now back to the V12 Jaguar Red beast.
