S7Horton,
I bought mine without having heard them first, something I thought I'd never do. "Bluebull" on this website convinced me to research the TSM's, and so I read nearly everything online I could find about them. At audioreview.com, you can follow the personal owner reviews as the speaker has evolved into its present TSM-MX and TSM-MM versions. I regarded reviews for those two as nearly equivalent for my purposes. The evidence convinced me to give them a try.
When I first got them, they were not what I expected. What set me to speaker shopping was lack of bass extension and dynamics in my CDM1NT's. I suppose I was looking for thumpety-thump. If that's what you want, go Paradigm. I quickly learned that's not what the Merlin TSM-MX is, although as they broke in, their bass got more extended. Instead, they reproduce accurately 97% of the music (everything but the lowest bass) of 99% of my eclectic collection. We listen to a lot of female vocals around here, but I like everything from Led Zeppelin to Johnny Cash, classical and church hymns. These speakers shine on everything, and just let me relax and enjoy my music. On the other hand, they tell you quickly what your bad recordings are. After some post-purchase comparison, I've learned I can trust them as a reference. Now, I have a thirst to buy more good music and to listen again and again to what I already have.
You need to talk with Bobby Palkovic at the merlinmusic.com website. He can tell you where you may be able to audition his speakers in your area, and where there may be a dealer.
