I have a pair of MA700's that i have had for many years..to me they sound great. I wuld buy again. its a british speaker company and when you call them you actually get a human being answering the phone. They have a 5 year warrantee on drivers and I have played mine daily for over 7 years and have never had any reason to call them on it.
I too heard the S6's, along with the LCR, S1 and S2. The S1 alone sounded fabulous to me. The S6 blew me away.
I've alaways said: the sound of speakers may be interpreted differently by different people. But, these made such an iimpact on me, that I am selling my PSB setup to buy the Monitor Audio's.
