Thank You for the update. After a few listens to the MoFi- let me know how the 2 discs compare in sound quality.

Happy Listening!

@xyzsantabarbara, Yes, for a small room you can get away with less power. But, it’s at 2 Ohms where you need it. The 3.7’s don’t just visit that impedance, that’s where they live. What you don’t need is massive amounts of power at 8 Ohms; they don’t go there. Keep in mind that 2 Ohms loads are about 1/4 as sensitive as 8 Ohm loads. It’s all about what the amp can do in the actual working conditions at hand, all else is moot.

@unsound I hear you. I have very good sound now, I cannot stop listening. However, I think there is still another level I can get with more power. I sent Rory Rail at Benchmark an email asking about a second AHB2. I know 2 AHB2 and the CS3.7 has been discounted on this thread but I wanted to get confirmation from Benchmark before I close the door on that.

I forgot how fast the C3.7 sounds. Just an incredible speaker. I am incredibly happy I went with the CS3.7 over the newer speakers I had demoed and liked a lot. I love the CS3.7 sound, it just feels correct.

I did some online research and I found out that 1 AHB2 in stereo puts out 259 watts into 2 Ohms.  That is not too bad.

They do not list any specs for mono mode at 2 Ohms.

I was not specifically pointing at the Benchmark. The Benchmark's are a somewhat unique, but perhaps not enough to be a clear exception. Most amps when bridged into mono don't like working into lower impedances. Benchmark does sort of dance around a 4 Ohm nominal recommendation when used in mono configuration. The 3.7's despite claims to the contrary are really below a 4 Ohm nominal load.  When taking the reduced sensitivity of 2 Ohms into consideration, it's 259 Watts 2 Ohm rating would comparable to about 65 Watts of power into 8 Ohms. That might be enough in a small room, but if you push it, it might lead to driver damaging clipping. Those 2 Ohm power ratings can often misleadingly appear to be providing tremendous power, but when one considers the reduced sensitivity it's really not all that much to work with.
