Tube Pre and SS Power? Or the reverse?


I posted a week or so ago about trading in my McIntosh MA352 integrated amp for separates.  

Now my question is, which goes tube and which should be SS?

I have received almost 50/50 responses, even from dealers.  

I have a big room, that has been acoustically treated, Revel Studio 2 speakers, and I'm running 2 SVS subs.

Some say I should go with a C49 SS pre and a MC275 Power amp = about $18k, less my trade-in.

Others say C2800 pre and a MC462 Power amp = $22k.

Quite a big difference.

Aren't some preamps more Tubi?? Lots of hybrid stuff going on.

It's always bothered me.  Gotta make sure you get something that's really reflective of what tubes are all about and not just a tube fit into the circuitry to make it seem like a tube device.  Examples that quickly come to mind are vac, Conrad Johnson, and audio research which I think are really Tubi.

Didn't know what people think is really Tubi and maybe I should start a thread. It's very sad my really good friend jay from Texas doesn't understand tubes. Nobody likes tubes, they're scared of tubes.

The very idea of hybrids is not a particularly good one. Tube phono stage and the rest solid state ?..Well, maybe, still questionable.

I concur with @100boardwalk. However, I don’t want to get into a debate over good, better, best and particularly not about branding.

I’m running an all tube system now after having SS systems and other Tube/Tube systems previously. Warmth with clarity was my goal and I found it in my current Tube/Tube system, ie; McIntosh C2600, dual mono-blocked MC275 through KEF Reference 205/2’s flanked by dual REL 812’s. This system gives me everything that I need to hear the music that I enjoy…

I’m an old bass player and drummer and have a decent ear for what notes are supposed to sound like and wanted a system that could produce the music as close to live as possible, which is the practically impossible task that this audiophiles is trying to achieve…Just sayin’

I'm more into the 'vintage' end of audio, so may not be entirely applicable to the OPs situation... but -

I have found the best combination (to my ear anyway) with is the tubes in the preamp and solid state for the power amps.

I run a modified Dynaco PAS-3X preamp into dual Mac MC2100s set up as monoblocks. This gives me the 'warmth' and presence of the tubes coupled with a basically unlimited power reserve (210 wpc out of each MC2100)... the other key is to have speakers capable of utilizing both the expanded bottom end subtleties as well as that high power reserve that such a combination brings to the table.

End result is as close to zero distortion / "muddiness" on those low bass / kick drum notes as is possible within the constraints of a 'vintage' system; combined with a better level of detail and nuance than either an all - tube or an all-SS setup could provide.

Going all tubes looks the 'coolest', of course - but unless your bank account is unlimited, you will face a much lower power output ceiling going with tube amplification. Some will argue that the higher power is not really needed at normal listening levels; I would offer that there is a distinct sonic advantage in having such a huge reserve to handle the millisecond power demands really impressive low notes put on an amplification system...
