Congrats @jafant

I find all the handwringing about whether a well designed solid state amp will drive the 3.7s surprising, given, as I've said, they were driven with aplomb, as loud as I could stand, by 140W of tubes (and even with a 14W integrated Eico amp).

But...we audiophiles gonna audiophile :-)

This new video From Ayre Acoustics and John Atkinson of Stereophile is just in time to explain why the CS3.7 won’t be liked by many amps, "especially bridged ones." And not only because it's closer to 2ohm rather than 4ohm

It’s got the discussed "equivalent peak dissipation resistance" (EPDR) which I mentioned a page back, which is the combination of -phase angle and resistance at a given frequency, in this CS3.7 case at 60hz where much power is needed.

@jafant Congrats. 

I was going back and reading this thread starting where I join in with my drama.  I had remembered that someone who actually owned the 3.7 and 2 x AHB2's AND was a classical musician said that the single AHB2 was preferred over 2. I always like to hear what a musician thinks of gear because they have more experience in real music than me.

Here is some comments emailed to me from John Siau on the compatibility in relation to Stereophiles comments.

3.8 Ohms at -40 deg is not a problem. You will not hit over-current shut down, even in mono mode.

The maximum SPL in mono mode will be about 6 dB higher than stereo mode.

The unique thing about the AHB2 is that it stays clean when driving low impedances and difficult phase angles.

Anyways, there is enough info now in this thread on the 3.7 + 2 x AHB2 synergy that we can put it to bed. People can make up their mid based on the great comments here. I am sure people would like to get back to regular scheduled programming.
