Interesting comments at http://lfd4u.com/?s=40.1 Can't do much about that bass 'hump' though on the early versions of the 40.1 I heard. Have the fixed that yet? Best I heard to date was the LFD PA2M (SE).
Prefered Amplifiers to run with Harbeth M40.1
As the owner of the Harbeth M40.1, I'm seeking advice from owners of this fine speaker as to which amplifiers they have found to be the most synergistic in terms of overall grip on the bass. I find the bass hard to tame and wonder whether going from tube to SS might be a better match. I'd like to hear from those who have compared tube to SS with my particular model. Associated amp is a Audiomat Opera Reference integrated.
