I own 2 of the 275s. I like them, but I'm a huge fan of Bob's gear. I'm still breaking them in, rolling all kinds of tubes but haven't decided on a combination at this point what with more tubes arriving and all. I can tell you they rock! In September right after I finished the build I was able to run them side-by-side with my EAR Yoshino V20 and they acquitted themselves quite well. I'll try and write a review as time permits.
