Aric Audio Systems Unlimited Preamp

I misspoke about delivery of the tubes. I should have them by 12/10.  I'm really looking forward to this experiment. 

Thanks Aric. Let's see how this works out in rocray's system, depending on his upstream/downstream components but in my current system which includes mostly tube electronics both upstream and downstream of the preamp, a more "laid back" presentation may not be as desirable. An all solid state system may benefit more from this change, albeit it'll probably be a very subtle change.

Well my Sylvania 5U4GB and GE OC3 showed up and are installed and running. The first thing I noticed was I had to turn the gain down. I'm letting things settle in a  bit. There seems to be a little more holography happening. I really didn't think that was possible. 
  
   tubepower,thanks for the recommendation,and Aric,thanks for the guidance in making this happen!  I'll post some more impressions as I get more time with this combination.

@rocray hey, thanks for the follow up post, that's awesome! Offhand, I can understand the soundstage possibly "fleshing out" more using the 5U4GB, for whatever reason it seems to have a more organic presentation than the 5AR4. The gain shouldn't have really changed at all however in theory, so that is a little bit baffling to me, but perhaps there's some other synergy that is occuring here between the preamp and amp due to this change? At any rate this is all good news and I'm glad to hear that you're digging it! Best wishes, Aric
