Amp for Thiel CS1.5?

Hi again folks,
Well I settled on purchasing a set of Thiel CS1.5 speakers to upgrade more to 2-channel from HT. I may live with my Outlaw 1050 powering them for a short time but know I'll need a separate amp from what I've read.

Thiel's website seems to strongly suggest getting an amp that will double the wattage as the impedence halves. Getting something close to this will probably narrow the field of contenders.

My biggest constraint is what I can spend on an amp right now. I can probably swing around $500-600 for the amp.

Any recommendations would be appreciated.

Just from reading I've wondered about a 70 or 100 watt from Classe, or that a Rotel might be a stepping stone until I can swing something nicer.

Thanks,
Chris

Thanks for the input folks.

Any thoughts on Anthem's older MCA 2? It is shown as being rated at 200/350 for 8/4 ohms. This doesn't quite meet Thiel recommendation for doubling when going to 4 ohms.

I'm unsuccessful so far tracking down the specs on units from PSE (Studio Mark IV) or from Muse.

Since I'm new at this in moving from a simple HT receiver setup, I'm unfamiliar with which amps would be "bright".

Thanks again,
Chris

I wouldn't let doubling down conern me but another amp to consider would be McCormack.

Chuck, the McCormack is a good recommendation. For someone new to this using the "doubling down" criterion has a lot of merit. The 1.5's hang around 4 OHms and drop to 3 Ohms.

The point of my comment, and I apologize for not saying this earlier, is that one should be more concerned about sound quality and system synergy. Obviously the number of watts required is a function of room size and acoustics as well as the type of music and sound level required.

Another amp that did a pretty nice job with my Thiel 3.6's was a B&K st140 I believe was the model number. A friend let me borrow his until my new amp came in and this should fit well within your budget.

Main concern would be how large a room you've got. If on the smaller side (appropriate for these speakers), even a decent push-pull tube 50-watter could sound better than many affordable SS 100-watters (that's the experience I had with my 2.2's in a smaller room), depsite the fact that tube amps don't "double down". Point is it's going to be the sound quality of what watts you do have that matters most, not the specs, and these speakers will please much more at your budget if you trade off high power for higher-quality power.
