Calling Harbeths 40.1 owners

I had a pair of SHL5 for a year before moving to M40. M40 is a much better speaker, but much harder to drive. I'm not sure whether this is applicable to M40.1. My room is 14 x 15 feet, have some room treatments when I got the M40.

Thanks Ashton, nice to know people are using them in spaces simular to mine and being happy. The M40.1 should be easier to drive and place than the M40. I have ARC VT100iii so there should be enough power. Do you need to place the speaker away from the room much?

I dont really think the 40.1 is a "better" speaker than the SHL5 when combined with a good (I used REL) subwoofer. Just different. Depending on your tastes, I put them equal when a subwoofer is integrated well into the SHL5 system.
I think anyone who really loves there SHL5s should make sure and hear the 40.1s before making the change.

Interesting Tom hankins, I do think HL5s have some good magic in the midrange. Can you detail what is thier differences?

I alway thought the M40.1 and HL5s have the same house sound but the latter being bigger and better in dynamics and details!
