I've owned a lot of PMC's over the years. I think the DB1i is the first small speaker I liked as much as an LS3/5a. (The Harbeth P3ESR is now the 2nd speaker in that category).
The TB2i's are a bargain. I love my FB1i Signatures. PMC offers sound quality similar to a Harbeth or Spendor Monitor series only with better imaging, tighter bass response and are much more room friendly.
The TB2i, for example is a grand cheaper than the Harbeth Compact 7 yet is only 7.75" wide, images like a mini-monitor, is 90db efficient and fits into small and medium rooms VERY easily. Like I said, a bargain.
