Thiel Owners

I have a pair of 1.5s and 3.6s, I used to run these with 

2xYamaha M80s bridged. I am not a loud listener but

It was apparent that 1 x M80 didn't cut it. I wanted to

get 2 x AHB2 amps but it was beyond my reach so

I chose 2 x Purifi 1ET7040SA Buckeye Amps instead

And I'm very happy with it so far. 

A lot of amps do not have published specs in the 2 Ohm region but that does not mean that it can operate there. My Benchmark AHB2 x 2 on the Thiel worked well but it did not make the low end shine.

My new speakers are easier to drive and I will like to get an AHB2 again because I miss that sound. I do like my current amp, the CODA #16 which would be great on the Thiel's.

I have a Magnepan LRS+ in my office ($999). It is a killer speaker but very had to drive like my old Thiel CS3.7. No way I would even try the AHB2 on it. It took me a while to find an amp to drive them. I now use the Sanders MagTech amp which is 500 and 900 at 8 and 4. It does not have published specs at 2 but given the explosive way it drives the LRS+. I am sure it is good at 2 Ohms. I was thinking this amp would be great with the Thiel CS3.7. 

I bought a used MagTech from the Sanders web site for $4k. Thiel users should consider it.

yyz - my only caution regards ''I am sure it is good at 2 Ohms'.

Consider that it already doesn't double its power from 8 to 4 ohms, so it is current limited by definition. I suggest contacting Sanders to find out how it behaves into 2 ohms.

Instead of speculating how hard they can be to

Drive. Here it is, some impedance measurements.

While not benign, I don't think it should be hard for 

A competent amplifier with large energy reserves.

Thanks For the detailed information about Adcom amps. My negative opinion came from using one as a loaner many years ago while my amp was being serviced. I see now that mine must have been one of the bad ones.
