Aric Audio Systems Unlimited Preamp

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

Thanks Aric. I'm enjoying this combo so much, I just ordered another Sylvania 5U4GB,and OC3.  First thoughts on the tube changes are larger soundstage,taller and wider,also,I find music has more "texture". So far, this is the best tweek I've experienced with my current system. Highly recommended!

rocray, thanks for the feedback. I think I'll try this combo as well just to see what difference it makes in my system. My Unlimited is paired with an older version of Aric's SE KT88 amplifier and upstream I have a LamizatOr Amber tube DAC. Lots of tubes to play with...all played through a pair of Omega Super Alnico Monitors. Glad to hear you're enjoying your "tweak".
