How to upgrade B&W Matrix Series 2

Those are good refinements to my query. I do like accuarcy in speakers and it is true the 801's let me know what is in front of them. I would not like to give up the bass which i now there. Rock is not my music but classical, jazz, and good vocal recordings are. To my ears the Threshold amplification is very good, though I may add a tube preamp at some point. It may be that improvements without five-figure list prices are hard to achieve.

Well, I'm not familiar enough with a lot of the newer speakers out there from smaller companies, but given your tastes and amplification I'd think that you might want to figure a way to audition some of the larger (3.6 and up) Thiel speakers, which need the power your Threshold can deliver, or a used pair of Dunlavy SC-IVAs or Alethas. Used these speakers would be in your price range. In addition, VMPS speakers might be an alternative if there's a way for you to find them, although I haven't heard them for years. They seem to be still made and from the reports quite good. Revel and Snell are two more brands that might interest you, although I haven't heard them. Finally, you might want to see if the B&W N804s deliver enough bass for your appetitite. It's tough for me to come up with speakers that can satisfy your criteria, as quite frankly the 801s are still excellent speakers and to get their level of resolution and bass extension today is likely to be expensive; in addition, since I'm a tube guy, I'm not sure how your amp would sound with most of today's speakers, although I would not consider it a weak link by any means. Hopefully some other members will have suggestions for you.

One other suggestion--perhaps the Vienna Acoustics Beethovens, which may be around your price range. I heard them sound surprisingly good with a large Krell home theater amp in a lousy acoustical environment, particularly with classical music. Most of the Vienna Acoustics speakers I've heard probably have a slightly sweet, maybe rolled off, high end, but they might work very well with your Threshold. Far more and better quality bass than I would have expected from a comparatively small enclosure, and very musical.

The 801 upgrades from North Creek may be an alternative. They are around $1600 and the web site, as one would expect, certainly makes them seem attractive. I wonder if anyone has any experience with them. Thanks again for the comments.

Maybe North Creek has some referrals, as many of the modifiers do? Or you can start a new thread to find out more about them. It certainly would be a cost-effective way of improving a speaker you obviously seem to enjoy. Good luck!
