New or used amp?

If you get lucky you may see an Audio Research D400MKIII or a Plinius SA100MKIII for sale on audiogon for under $2K. I haven't heard all the other amps memtioned above but I now for a fact those 2 will beat a Bryston hands down and better any Krell for under $8K. Levinson starts to get really good amps about $3K used. For my money it would be the ARC though.

Hey Thought I Would let everyone know I have a VTL 2 Preamp,
Epos ES-11's, VPI HW19 Jr.& McCormack Phono Drive. I'm changing
speakers later this year.

Risking some negative comments, give a listen to the Creek 5350SE integrated, 85wpc, available from time to time at about $1150 used. If you like it, you can sell the preamp and buy more vinyl! See the Stereophile review, but I'll tell you my Creek/Alon Petite bedroom system sounds darn near as good as my $20k retail living room system.

The best you can get (in my opinion) for that price range if you are considering tubes is the VTL ST-85. You can get a used one for about $900. This Amp is excellent in every way. Great bass, highs and superb vocals and very liquid. I have this matched with Muse Model 2 DAC ( about $450 used with Bessell filter), Theta Data Basic ll ( about $500 used),Plinius 12 pre-amp, Reference 3A La Suprema speakers and Siltech cables. The combination is just amazing. Another one I'm considering is the Manley 50W Monoblocks. Good luck on your search.

If you want waranty and phenomenal sound, you can get a new Musical Fidelity A3cr for around $1500. They are truly wonderful sounding and Stereophile "Class A" (if you care). To me they sound much better than the 4B-st unless you need the extra power (the 4B-ST is the champion in the WATTS/Buck category).
