Cary CAD-211AE tube rolling


I have done a search but have been unable to find a similar thread. I am after opinions from people who have tried tube rolling their CAD-211's.

I have replaced the standard Chinese output tubes with a quad matched set of Shuguang Psvane 845's from Grant Electronics. They took a long time to burn in, but once they did they are a definite improvement over the stock tubes. Wider soundstage, more detail, and better dynamics.

I have also replaced the no-name 6SC7 input tube that came with my amp to an Electro-Harmonix 6SC7, and then a vintage RCA 6SC7. The EHX was a downgrade from the standard Chinese tube, sounding muddy despite burn-in. The RCA is a definite improvement, with much better micro-dynamics, resolution, and a more lush presentation.

I am now after a new 300B. I would like to try the KR, but these are now very expensive. Emission Labs make a few (including a drop in replacement for the Western Electric 300B) - these are available in plate and mesh forms.

Cary 211 owners - what 300B's have you tried in your amp? Or for that matter, what tubes have you tried?

I realize this is slightly off topic, but I was wondering if you could characterize the differences between the Cary 805 and the 211M.

Thanks much!
Thank you for the excellent reply. Your comparison between the two amps was very helpful!
