I haven't heard the other speakers but I own the 30.1. It is very far from being a "rock n roll" speaker, if you're into that kind of music, the bigger models are probably much better choises. However, if you mainly listens to acoustic music with lots of vocals, the 30.1's are probably tough to beat by any other speaker model or brand.
Harbeth Owners which model?
I am looking to buy either a M30.1, SHL5, or M40.1. I owned a SHL5 in the past for about 3 years and totally enjoyed it and have regretted ever selling them. Since I sold the SHL5's a few years ago Harbeth has come out with the M30.1 and I wanted any feedback from anyone who has compared the 5's vs. 30.1? Anyone sell their 5's for the 30.1 and why? Lastly I am also interested in the 40.1's my room is 18 x 14 is that big enough to handle the 40.1?
