Very Nice set up. As tube gear goes..yours is primo and superb sounding. But, this kind of tube gear quality is anything but "tubey" so to speak... and is really far more neutral and with much better detail,resolution, depth,space and balanced at the Freq. extremes than your typical tube gear sound. I wouldn't recommend tube rolling with this equip..CJ has done very well with the chioce of tubes for these applications. I do agree with Potsey, perhaps changing IC's would be an avenue to explore.
I have listened to the Nu Vista 3D and found it very involving and musical..better than my Wadia 23, which is not as warm over all.
Best of luck with your system!
