question about ss or tubes


So right now the sound I'm getting is wonderfully enveloping and fills my little space up with the music.  The music has reasonable amount of depth it images beyond the edges of the speakers and sometimes sound comes from behind me or right next to me. However I know I'm missing some detail and it has me contemplating a phono stage and I'm just wondering would I lose what I have going to solid state in order to get detail or is it possible to keep this spacious floating sort of presentation with something like a Sutherland 20/20 for example. On a side note I'm getting some new power tubes for my amps so I think this should help with my detail but my question is still does solid state do this sort of presentation or is not a ss or tube question at all but a system room synergy thing that causes this.

I have a sign that says "no experts allowed" outside my front door, so that solves that issue…although they do sneak in from time to time and I have to fumigate...Room correction issues can be messed with by using one of the room correction gizmos (officially called Electronic Nannys) in the signal chain, although I personally refuse to allow somebody else's bass attenuation/compression formula into my sanctuary (let alone my listening room). I find that a small flock of sheep trained to avoid blocking my speakers from reaching me at my sweet spot does work, but cleanup is bothersome and they're often noisy. I go through a "too live" room thing every time I mix a concert where the venue is empty during the sound check…I've considered filling the room with the aforementioned sheep (same issues as before), fully dressed wax figures or manikins, or simply quiet people who don't mind sitting through the sound check and then getting the hell out of there until showtime. More to the point (what was that point anyway?), I don't care who likes or doesn't like tubes but I do know tubes are more fun. That is a fact.
Nice coming home to read the above responses. Thanks guys. Smrex13 that was just the first hand experience between those units I was looking for. Very sweet. It seems and I'm just thinking out loud, that I see more chinooks on the used market than I do the Sutherlands and I would love to know why that is. 
Minori, I'm with ya I'm not in an either or frame of mind myself, yet. As I learn about what's important to me it seems those qualities come from tubes. But that could change to. I'm really attracted to quiet black backgrounds and great stereo separation with units that are dual mono like the whests and liberty's, et al., both of which seem to be great strengths on the solid state side. 
WolfG, cool job dude. I'll trade ya. 
You have a very nice system, I would look at upgrading your grado cartridge, it's strengths do not include loads of detail.  Good Luck
Thank you for the compliment and I can't say I haven't thought about the cart myself. Out of curiosity I auditioned the Dyna 12d3 I think it was. It's the one that has the super short diamond cantilever. That went into one of Bobs devices. I had no expectations but I could not believe how badly it sounded. Like nails on a chalkboard, detailed yes, but noisy, brittle. I wasn't sure what to think. I set it up carefully. I'm a complete noob with mc. That was my first try. I was thinking that it might have been because my system is tuned around the Grado and maybe that's why.
 A 12au7 in the linestage went out recently and I'm currently running from the tape outs of the Quick and into a passive that has brought about a nice degree of refinement and detail. It is one of the reasons that has led me to really consider what a less long in the tooth more modern option might be able to wring out of the grooves without losing the essential character of what I love about the sound. If I did go for a cart change given some of the background, any ideas? The Grado is gonna need retipping or exchanging in the not too distant future. 
Grados do fine with detail- just like any other cartridge, care and feeding is important (IOW they have to be set up properly).

When was the last time you got the tubes tested in your Quicksilver? Maybe they just need replacement?
