Tube Preamp --> Solid State Amp


I had an interesting conversation with my audio dealer today.  I was demoing the Focal Supra 3s and he shared his opinion/preference that he likes to choose a quality TUBE preamp (ex: McInstosh D1100) paired with a SOLID STATE amp (ex: Michi X5 integrated, McIntosh MC312 power amp etc).   Not sure if there are any schools of thought promoting or perhaps indifferent to this approach but wanted to get some thoughts?

Specifically for me, I just bought a Michi X5 (integrated amp) and am picking up some Focal Sopra 3s.  I have toyed with the idea of dropping in a tube preamp to soften/warm up the sound prior to the X5 giving it that 600w of punch @ 4Ohms but don't want to throw money away.  

I will say this, when I demoed the Focal Supra 3s, I did so on McIntosh tube preamp and McIntosh  SS Amp, and then switched immediately via a button on the McIntosh premap but using the McIntosh 275 TUBE amp.  The 275 added so much softness and warmth that the Focals almost felt muted.  It was about the best A/B comparison I've ever done. 

I know this has a lot to do with speaker pairing but was just curious anyone's thoughts on tube vs SS for separates?

I have a McIntosh c2300 mated with an MC500, my digital is via a d150 thru the c2300. I couldn’t be more happier. It’s the best of both worlds, smooth midrange from the tubes and the slam of bass when needed from the ss amp. I have very efficient Tannoy Churchill’s so that’s part of the equation.  I highly recommend going this route. Good luck. Oh use good tubes. I use medical grade Amprex. 

Most integrated amps will let you use the preamp feature as a separate, but not the amplifier feature. For instance, my Hegel integrated always has the preamp in the circuit, even with the HT bypass on.

All the best.

First, I must correct that my amp is an F8, not F7. Rated 15 dB gain. My Focals are the 906 Arias, rated 89.5 dB sensitivity.
 
No problem with volume. My ears are 8 feet from the speakers. They never sound as though they have not received the power they needed for a passage.
