Impressions:
Better imaging and a lot more control over the various instruments/vocals. What I noticed first and foremost was that this is very transparent, natural-sounding, and musical.... moreso than even my prior preamp (in direct A/B comparison). On top of that, the fact that when I turn up my system - the imaging remains coherent and solidly focused is a BIG improvement!! With my old preamp 98, once I turned up the volume knob to about 80-90db, I'd begin to lose coherence and the image of the singer would begin to ENLARGE! Not realistic and I thought it was the fault of the panels (again, I mistakenly blamed the Summits)... but this 05 preamp has some control over the signal (and in single ended, mind you!) where it maintains coherence even when the going gets tough and a lot of instruments occupy the stage. One thing I noticed with the 98 was a "muddling" whenever things got very hairy in the recording, and was one reason why I preferred solo instruments over complex pieces.
I'm glad the 05 improved on the overall coherence of my system... it's beginning to sound real good now. I can turn it up and the image remains relatively normal-sized.. while allowing a more realistic reproduction of the ambiance of the recording studio/hall! It's impressive how wide my soundstage is.... you guys have to come over and hear it for yourself.
I know I've heard better, but this is getting to be really scary good. I'll write a full report once I have time. For now, it's time to enjoy the music.
Improvement for the future...
1. I think I can hear a bit of high-frequency artifacts at times.... I think this is because I lack room treatments. Once I finish my home-made DIY treatments, I'm going to take pics once I get them up.
2. I need balanced xlr interconnects to truly run my system in balanced mode from the PS Audio III DAC -> Cary 05 preamp -> Plinius 102 amp! I'm going to ask it for Christmas. I'm looking forward to another increment of improvement in sound.
3. I think I could use a better source, but I'm going to slow down for a few months until I find one that can replace my fully-balanced PS Audio III. Perhaps another Cary unit?
4. I have a lot of 6sn7 tubes in my possession so it would only make sense to tube-roll my preamp. I'll do this after I get back to my apartment this weekend.... Sunday night. Something to look forward to!
5. I need some headphones now.... I think I'm going to ask for a Sennheiser HD-650 from Melissa for Christmas. I had those same headphone before, but I sold them to buy the Vantages. Gotta get them back in here.
