Suggestions-New or Used $3-4k Tube amp w/ Usher

i am running some usher cp-777 from the dancer series with the new beryllium tweeter with a marsh 400 amp and a vtl.5.5 tubed preamp and the sound is very good.
i have driven the same pair with a 50 watt tube integrated
wich did not have the same grip on the bass as the marsh but was very enjoyable sounding.
i have heard that usher speakers are best driven with transistor amplification but my experience with these shows me this could be wrong.
anyways, getting a pair of the new usher r.1.5 power amps
soon, rated at 150 watts per channel(360 watts as a mono)
in pure class A ,we will see if thats a match made in heaven.
afterwards....a pair of ASL hurricannes for big tube power to see how the usher r-1.5 fares compare to it!
will be back for more details after auditioning seriously!

You sure will love the Apl 3910 I loveit.
I found your reply interesting, considering I bought some older,in very good cond. VTL Deluxe Monos on Monday. I thought I'd experiment with used and go from there.
Thanks, Tom

I'm mailing a check to Alex tomorrow for one of his 3910's and I plan to run it into my VTL Sig. 250 monos. I was at CES in January and heard his player in a couple systems. Both were very good and I mentioned I'd be using the VTL's which he said would work very well.

Also, I work with a local dealer who handles both Usher and VTL and I've heard several of their speakers, both at CES and at a couple friends. I believe they would be a great match plus you should be able to find a pair of the 250's on Audiogon in your price range. The 250 is better than the 450; I've heard both several times.
