PMC ,Harbeth or B&W?

I'm not familiar w/the PMC's, but I have owned the Harbeth's you've mentioned. Given their cost and the need for 1st class associated equipment to drive them, I would not repurchase them. Given the size of your room and your taste in music, I would highly recommend you consider the Spendor S3/5. An excellent spk., thought not very effecient. Also, an excellent spk. is the JM Lab 705. It has a metal dome tweeter, but it's voiced slightly on the warm side. It's being replaced by a newer model, so I wouldn't delay deciding too long on these. Energy makes excellent speakers as well. The C-1 is superb especially given its very modest cost. The older XL-15 bookshelf spk. is very good as well. If you decide you'd like to give the Harbeth's a try, be sure to enquire w/your dealer about a possible in home trial audition to see if these float your boat. Good Luck!

DB1 sounds very much like Quad 12LS i used to own...very detailed,transparent, and excellent imaging...however....like the Quads...I found them to bright and fatiguing...they both have exceptional bass for monitors...what is up with the Brits these days?...they seem to love this analytical sound at the moment(both captured Product of the YEar awards)...I would venture towards Harbeth or Spendor...good luck...
