Best Amp for my Pipedreams and ML 32

First of all, thanks for all the very helpful responses.

Sorry I forgot to state that I also have the VAC Master Controller Preamp and can also use that with the Pipedreams. The only qualification is that I want to use ss, not tubes for my amps and that I want to biamp the system. I would consider selling the Krell if the synergy issue is a real problem.

Any thoughts regarding SS amps with the VAC preamp?

The biggest problems that i've seen with trying to run a tubed preamp with an SS power amp had to do with impedance mismatches. Due to the way that most gear is ( poorly ) designed, you have to factor in a HUGE impedance mismatch when going this route. That is, most tubed pre's want to see a very high input impedance on an amp. Trying to run a tubed pre with an SS amp that has a lower input impedance typically results in a very warm, syrupy thick bloat that sounds terrible. So long as you can keep the input impedance of the amplifier kind of high, you shouldn't run into too many problems. Otherwise, you may end up spending a fortune on cabling and tube-rolling trying to resolve a basic electrical mismatch. Sean

I use with 21 Pipedreams :
digital :EMM Labs Meitner combo SACD+ DAC6e ( cd+ sacd) the best
analogue :Forsell Air reference+ Forsell arm+ Lyra Clavis
phono pre amp ( two chassis all tube)*
preamp (two chassis all tube)*
for mid \treble amplification:
two OTL monos 550w each in 8 ohms ( pl 519 tubes)*
*( produced by me and a friend)
for bass
QSC pl6
All nordost Valhalla and Shunuata Anaconda and 2 Hydra 8
this is the best sound i got from 21 pipes: coerent,fast; detailed,musical ,non fatiguing for all levels and kind of music
Crag Oxford,boss of Nearfield Acoustics and Audio Emotion Audio had heared my system at my home in Portugal and ... ask him his opinion, he has bought from me same amps afterwards...

Before i tried Spectral gear,Audionote gear,OTL Tenor w75 with Krell,and Qsc 4050 but no coherency and musicality at all

I have pipe dreams with all new drivers and just use
audio reasearch 600 tube amps and accuphase dp-700
with all nordost valhalla cables.Amps were plugged into
their own deacated wall circuits,now I use audience
arp2t that plug into wall with no powercord,amps plug
into them,just the best
