Welcome Ivor. The Paradigm Studio 60 has a similar sound to the M60s if you are able to hear a pair of those and I believe some have said the PSB Imagine Series (NOT Image series) has a similar sound. I can attest to the similarities between the M80s and the Pdigm Studio 100s, I own M80s and auditioned the 100s which were quite close...detailed, with power to spare and wide range.

Half of communication is listening. You can't listen with your mouth.
