Larry, that was a well written and thoughtful review. Thank you for contributing to Audiogon's member reviews.
I'd like to make a suggestion. I can see you are a discriminating listener, and you have wisely chosen tubes as your source equipment. I, too, owned both your Kora preamp and VAC Ren.(the 30/30). They are good pieces, but I would venture that they are now the weak links in your system.
I auditioned an Audio Valve Eklipse from Victor of Fanfare in NYC while I still had the Kora. Though it is not a recognized brand, this German linestage surpassed the Kora by a wide margin, and the build quality is typical German overbuild. Needless to say, I replaced the Kora in a heartbeat. Replacing the stock tubes with vintage Telefunken's only increased the gap. You mentioned your appreciation for rich midrange without harshness and loss of detail. That description fits the Audio Valve to a 'Tee'. The Kora is quite lean by comparison.
I loved my VAC until I gave a serious audition to Audio Research. I never realized how colored and unbalanced the VAC was until I heard the ARC VT100 mkII. I have since graduated to the VT200. Of course, ARC has created new models, but their tradition and sonic signature continue.
Both the Audio Valve and ARC are very reasonably priced, especially in relation to the cost of your speakers. You may want to audition both brands, if you are daring enough.
