Attention Thiel CS3.7 owners


I am searching for the right amp for these speakers and was hoping to hear from as many 3.7 owners as possible regarding what amp you are using, why you like it and which ones you have not liked. Thanks in advance for your help with my quest..

I just bought Thiel CS 3.7s last week. I auditioned them at my local dealer with a 100 watt Macintosh tube amp and a Mac pre, which reproduced wonderful sound and were at least somewhat comparable to the performance of my VAC gear at home.

I also auditioned the CS2.7s, which sounded great in so many ways... but when we hooked up the 3.7s and played the same reference track... well, after the first three seconds of listening, I knew I was done for. I had to spend the money, as I've never heard anything like what these speakers pulled out of my records. I believe this speaker is a true breakthrough in high end loudspeaker design and will come to be known as the best value because to get this quality of sound, you could spend three or four times the $15k these cost. Which of course, means that matching amps is critical. 100 watts of high current tube power is the starting point.

I thought i had an idea what they would sound like at home, but i wasnt prepared...what I'm hearing with the 3.7s being driven by my VAC gear (Signature 2a pre and Phi 200 amp) is breathtaking. it's actually hard to describe the magic coming out of them. The sound is just gorgeous! And that's right out of the box. They will continue to improve for the next 400 hours of use.

Paired with my amps, these are the most natural sounding speakers I've ever heard. Powerful, articulate, revealing micro details without brightness or edge, a midrange to die for, excellent feel in your bones bass, incredible soundstage and holographic imaging... I know, you've heard all that before, but when you hear what they can do with strong tube amps like VAC, well, like I said, impossible to describe the experience fully...like mailing a haircut.

As for reports of being bright or lean -- well, everyone's ears and systems are different. In my home, right now, listening... I'm blown away by how alive and real my rig sounds. The bass is musical, effortless and taut, with absolutely no bloat. 

Been doing this crazy hobby (read "obsession") for forty years and I've never been more excited about my sound system.

I think that aside from some tweaks here and there, my system has reached a level that is completely satisfying. I know, audiophile heresy, right? I am now going to rediscover hundreds of my albums. So my recommendation, the VAC Phi 200 or any other VAC component you can get your hands on... They will make your Thiels sing.
Alonski,

Interesting, I have the 2.4s now. I have been going back and forth between the Revel Studio 2 and Thiel 3.7s. I have heard the Salon 2 and 3.7 a good number of times.

Anyway, back on topic I don't think you need 375 watts unless you listen very loud. You just need an amp with stable current output. I have heard the 3.7 on tubes (150ish watts worth) but it was a little boring for my tastes. I listen to hard rock mostly (some audiophile stuff ) and value bass impact and tend to like amps with a high damping factor.

Honesty, I have really enjoyed class D amps because they handle the bass so well. However I don't know that I would recommend them to some one that listens to jazz and classical (I don't) because you give up some of the cleanness in the highs.
Alonski,

Isn't it great when a purchase pays off? Thanks for sharing about the VAC
gear. Just curious as to what types of music you generally listen to and how
big your room is. Congrats on joining the 3.7 fan club!

James63,

My preference for watts is not meant to be a statement of orthodoxy. Every
system and room is different. I simply know what I need in my room and in
my system. With the 3.7's, I don't covet more watts in order to raise the
volume; I have found that the "ease", "finesse" and
"agility" of the 3.7's cannot be fully realized with the lower watt
amplifiers I've auditioned. That is not to say that the 3.7's can't sound great
with lower watt amplifiers.

After five years of living with these incredible
speakers, I'm now shooting for something that will help them do their very
best with all types of music. My musical tastes are quite diverse and
eclectic, so it's a tall order. As you say, If I just listened to jazz, I'd get a
great 150-watt tube amp and call it a day.
James,
My musical tastes are very eclectic, so I need a speaker that can load my 23X23 room for listening to all my musical genres. In my reference collection that I use to audition sources, components, cables and speakers, you'll find some amazing tracks from superb classical recordings, old jazz, as well as brilliant cuts like ZZ Top's La Grange, Ted Nugent's Stranglehold, Jeff Beck's Goodbye PorkPie Hat and other well recorded uncompressed rock. When I demonstrate my system, I use every genre, and invariably, my guests are stunned, especially by the sheer power of the hard rock tunes. The room just lights up with music that sounds live and sweeps you out of the room and to the recording venue. I usually have to clean up the drool on the carpet after the demo.

The Thiels replaced Von Schweikert Audio Unifield 3 and a pair of REL subs. The U3s are amazing in near-field listening, and with the subs they really rocked, but they don't compare with the ridiculously good performance of the 3.7s in my open plan living space. I still have the subs and will audition them with the 3.7s after the break in period. I believe that most, if not all systems benefit greatly from correctly set-up subs. I'll keep you posted on that.

Vhiner,
My next upgrade is adding another VAC Phi 200 so I get all 200Watts for each channel... I just don't have a place for another amp right now due to WAF considerations. VAC amps are known by fans as being able to control and drive excellent bass from power-hungry speakers. The 100W per channel they put out doesn't sound like much until you realize the massive amount of current they generate. There are no wimpy amps in the VAC line-up. Current is king for bass impact. I fantasize about the VAC flagship amp that puts out 450 per channel, but the monoblocks are about $80,000.
Alonski,

I read the specs and a few reviews of the Phi 200 and it's clear the monoblocs have what it takes to handle the 3.7's 2 ohm dip. Not many tube amps can do that. How many hours do you get out of a tube set?
