Harbeth SHL5 vs 40.1


I currently own the Harbeth SHL5's and I'm considering upgrading to there 40.1's but I'm wondering how significant the improvement is based on the bucks that these speakers cost. Anyone have experience with these speakers? My Amp is a Cary 120s tube through a Cary SLP05 preamp.

Markus - Is your tube amp a good fit for the M40.1's... does it have enough juice to control the bass? I've always wanted to try a tube amp (thinking McIntosh MC 275) and may eventually go that route after some research just to try something different.
I have not heard my amps with the 40.1s, but with my SHL5s the Manley amps are killer.
