Tube preamp options

My system from the preamp on consists of a rouge rp-7, rogue m180 monoblocks, and vandersteen quatro wood speakers. My main source is a brinkmann Bardo through a Rogers PA-2 phono pre. It all sounds great. But there's that itch, you know? I get tremendous soundstage but not that much depth. Clarity is great, mids are nice, bass is excellent. But it doesn't quite have that in the room sound that I'm looking for. The RP7 sounded too solid state and analytical for me out of the box with the stock JJ tubes so I've done extensive rolling. Been through all sorts of NOS tubes and landed on amperex as they seem to have the best balance of warmth and clarity. My thought is, maybe I can find a pre that has those attributes out of the gate without all the rolling. Don't get me wrong, I like the idea of being able to tailor the sound with trying different tubes but I feel like maybe there's a brand out there who's house sound I like better. I haven't listened to anything more yet but brands that are on the list to check out are Backert labs, maybe a used ARC Ref 6, VTL, VAC. There are a million little boutique brands tho and I'm asking what people have heard in the 10k price range, new or used, that might be a good fit for me and why. 



I heard the octave audio HP 300 SE at RMAF.  Really nice equipment.  Had it paired with the own amp and some Dynaudio towers.  Sweat sound. 

The simplest way I can describe is it brought life to the music.  Maybe more detail, space and deeper soundstage.  It made everything a little bit nicer at least to me.  

Yes I bought the ultimate upgrade with Kimber cable.  I also worked with Brent Jesse and upgraded to NOS tubes.  One on the reasons I went with the Cary is I am a big supporter of tube regulated power supplies.  I am currently using a metal base GZ34.  I had a few of these from my Modwright days.  The GZ 34 had the most significant improvement to SQ I've experienced with most equipment changes.  

OP - Johnny R is a great dude and has setup many Quattro in many rooms. If you go down the path of pulling them out, which is a worthy experiment, make sure you rerun Vandertones AND especially revisit the Q setting to get back some or all of the slam if you feel it’s lacking.  Get in touch IF i can help in any way. i do a lot of FREE Vandy setup work because it keeps me sharp… well, maybe sharper…

BTW my brother runs a Cadenza Black into Vandy thru an ARC / Threshold chain with superb image depth. Good on ya to expect better… you will get there…
