Best speakers for amp


Hey folks,

I'm looking at upgrading speakers from my B&W DM601S2s. I currently run a NAD C370 with NAD C541 CD Player.

I'd like to keep my amp...how much do you think I should spend maximum on my speakers before I'd need a better amp? Are there any models you would recommend?

In upgrading, I'd like to improve the presence, imaging, and soundstaging, as well as enhancing the bass response.

Any examples of speakers used with this amp? I've thought about the higher end B&W models, such as the DM602S3 or CDM1NT. I've even considered the Nautilus 805s, but would I be wasting money?

Thank you for any help you can provide.

I forgot to mention one thing...I would like to bi-amp as well (probably using the C270). In this case, would a more expensive speaker like the CDM1NTs be worth it?

Thank you again for all your help.
Better speakers can only hurt if they reveal shortcomings in your other gear. The CDM-1NT would be fine with your setup. Have you heard the new B&W 600 series 3?

In the past I have purchased Vandenhul new, directly from the US importer in New York state (see VDH website). There are some Agon dealers in the classifieds that sell them. Places like AudioAdvisor.com online have a good selection of cables. See there demo/clearance section too. Then there is The Cable Company (www.fatwyre.com) and their companion site (www.usedcable.com)

For wire, I'd try Acoustic Zen.
For speakers, look at http://tyleracoustics.home.mindspring.com/

I would also recommend trying new amps first though. Not knocking NAD, but there is better out there.
If you were to venture into HT, I'd look into MIRAGE loud-
speakers. They are easy to drive, sound great with any SS
int. amp./receiver and have a wonderful soundstage.(www.tsto.com. The Stereo Trading Outlet is selling Mirage
790 loundspeaker for $495) The VDH D102 interconnect is an
excellent cable. I ordered mine through hificables.co.uk. If I were to consider B&W CDM 1 NT/805's, I would most certainly look into a higher level of amplification. IMHO,
B&W's need a high quality tube amp/or warm SS amp to sound
musical.
I just upgraded to QED Silver Anniversary Bi-wire and VDH D102 III HB interconnects.

The difference is quite subtle, but is definitely there. I did a slow transition to both, and the D102 III HB definitely improved the high-frequency clarity and a little of the bass response. The Silver Anniversary opened up the sound a little afterward, separating the instruments a little better, exposing the mid-range more, and improving the bass response a little.

The end result generally is a more smooth, detailed, and open sound.

I am thinking of putting off any upgrades for at least half a year, because this hobby is getting expensive!
