It is so hard to go wrong with Harbeth with any quality amp choice; I prefer SS with mine. an ARC amp would be a great choice. Eweedhome and I seem to be cut from the same cloth. I too found the M30 a little to much after a while and I much prefered the C7 es3 (plus, they are less espensive). Later, I got a sub to go with them, and I am really enjoying what I am hearing; I listen to a lot of classical and the full range I get now with the sub is a tone of fun. Smiles and goosebumps everytime :)
