Speaker upgrade - please advise.


Hi, I'm looking to upgrade pretty soon - most likely speakers, and I'm looking for any ideas you guys may have on the right choice. I'm looking to spend up to $6,000 used. My current system is listed on in the 'virtual systems' on Audiogon, but here goes:
Bryston 4bst power amp
Sonic Frontiers Line 3 Preamp (with tube upgrades)
B&W Nautilus 805 speakers
MSB Link DAC III & Monolithic Power supply & Upsampling
Muse Model 5 Transport
Kimber KCAG, Cardas Golden Cross analog interconnects.
Nordost Silver Shadow digital interconnect.
Stealth Triple Ribbon & PC Premier speaker cable
PS Audio 300 Powerplant
3 Shunyata Sidewinder Power Cords.

I'm thinking of moving to tube amplification at some later date (BAT or Sonic Frontiers), so will need speakers to match that set up. The speakers I'm really considering are Dynaudio Confidence 5. I'll also consider B&W Nautilus 802, but suspect there's better out there at the price. Anyway, any advice is much appreciated (also, if you see other potential upgrades in other components, let me know). Thanks!

You've got a lot of choices for $6k used. If you can stretch your budget just a bit more -- say $7500 -- you can probably get a used pair of Vandersteen Model 5's, which are a terrific speaker. If you need to stay under $6k, you should consider the Coincident Technology Total Eclipse or Super Eclipse; the Magneplanar 3.6's; the Martin-Logan Prodigy (used) or Ascent (new); Meadowlark Heron Hotrod; Vienna Acoustics (can't think of the model, but it's one step below the top-of-the-line Mahler); and Dunlavy SC-IV's. I'm sure you'll get other good recommendations to go with these.
I'd opt for the N802s: they are considered in the top-tier, with Revel Studios, at $8000, new. At $6,000 you should get a great deal.

I've have an array of them, and they do sing.

Forget Dynaudio or Martin logan if your considering tubes.
Both of these speakers are hard to drive and have nominal
impedance of 4ohms or less. Watch who you take advice from
there are some know it all clowns out there.
Plan your system before you purcase, audition everything.

Not only do you have the coolest name I've seen (Tubegroover's bumped from the top!) You have common sense and gave great advice!!

Now for my .02...... How anyone could listen to B&W speakers and an amp as bright as Bryston (yes, I'm sure many will attack me for this, but it's what I hear in this setup!) Get a smoother amp and less harsh speakers!
