SS Preamp with Tube Amp?


I have always been a SS audiophile: Plinius, McCormack, Pass amps and integrated's. I still have a few of them in several setups.

But recently I bought a Music Reference RM10 MKII, an EL84 35 wpc tube amp. I love it. Have it driving Spendor A6's. All cables Furutech.

My question is, can a SS preamp do the tube amp justice to maintain the tube amp's liquidity, sweetness, wonderful midrange, etc.

I was thinking about a Jeff Rowland Capri SS pre.

Wondered what others' experience has been with this question.

Thanks

As noted by others, there have been a lot of threads on this subject and you should research them.

Truly good sounding solid-state preamps, which is to say, the ones that do not sound "solid-state", tend to be very expensive, and I agree with the above poster that it is a lot easier to get a good sounding tube preamp at a given price point than solid-state. Most importantly, tube preamps layer space better than most solid-state preamps.

That said, the very best solid-state preamps layer space just as well as tube preamps. They are also quieter, and this to me is crucial - tube pre's obscure detail compared to the better solid-state preamps because of the greater noise levels generated by small-signal tubes. A preamp sends a signal that is amplified many times by the amplifier - if the signal received from the preamp at an amp's inputs is noisy to begin with, noise levels become quickly audible. In a high-resolution system, a solid-state preamp allows a listener to hear deeper, and with the best SS pre's, a lot deeper, into recordings.

Except for those that are output transformer coupled (most are not), tube preamps have high-ish output impedances and often have bass rolloff problems with amps having low input impedances, compromising compatibility. They also tend to have trouble driving long (>2 M.) interconnects, again limiting compatibility. The only inconvenience I have encountered with SS pre's concerns powering them down for electrical storms - tube preamps come back to life within a few hours, while a solid-state pre's need a lot longer.

Turning to your specific question, the issue with running a solid-state preamp with a tube preamp again comes back to cost. Just as it takes a very good (and thus very $$$) solid-state preamp to get past solid-state preamp problems, it likewise takes a lot of money to get into a tube amp that does not have typical tube amp problems, specifically, an inability to control woofers and non-linear frequency response due to impedance issues with dynamic (cone) loudspeakers - the amp has to have massive power supplies and most importantly, really good output transformers, which are really expensive. In the alternative, you can get a hell of a lot of performance from a relatively moderate-cost combo like an Audible Illusions 3A tube preamp with a Bryston or McCormack SS amp.

At the top end of the market, however, a solid-state pre is the way to go in my opinion. I run a very quiet solid-state preamp (battery powered, fully differential balanced Rowland Coherence II) with either solid-state (darTZeel) or triode tube (VAC Renaissance 70/70) amplifiers. The Rowland's output impedance is a really low 50 Ohms, which can even drive the darTZeel through its 50 Ohm input. My backup preamp is a solid-state ARC LS-3. I've owned some pretty decent tube preamps (Jadis, Hovland, CAT), I've heard many others, and love what they do well, but believe that, generally speaking, very high-end solid-state is best at the preamplification stage with either tube or solid-state amplification.
Put Klyne on the list for consideration;Stan's pre amps are highly regarded and build quality is first class;only I think you need to get off the couch,no remote as I recall
unless he has one in the works;been a while.
"Truly good sounding solid-state preamps....bla bla "

I thought the whole idea was "strait wire with gain" ?
Shouldn't a "really good" preamp shoot for nutrality and thus have no "sound"?
I share the same opinion as 6550c in that a preamp should be as neutral as possible. This is why I prefer using passive preamps. While I have had some nice active preamps in my system, and have sat and listened to many others, I always seem to gravitate back towards a passive design.
Raquel raises an interesting point about the problems associated with both types of pre-amps and power amps when frequent electrical storms, i.e., outages as well as possible strikes by lightning, occur in your location. Is that reason enough to choose tubes vs SS? Is it true that tubes come up to an optimal operating status quicker than SS devices after power is turned off and then back on? With more power problems, especially in summer peak demand periods, as happens with increasing frequency in the D.C. suburbs here in the Mid-Atlantic region, should this consideration be given more weight in choosing tubes vs SS? I do not have hours to wait before I can listen to an optimal sound after a long day at work.
