bi amping question

Based on the many posts involving "musicality" there's no doubt it is a nebulous term and connotes many different definitions/descriptions.

To me musicality is simply enjoyment of the component's sonics. If you accept this, then musicality is subjective and varies from listener to listener.

I wouldn't know how to define it any other way.

OOPS- I never replied to your query about the 6SN7's. It sounds like our tastes are similar. If you want the Holy Grails of transparency and sound stage: There's nothing out there like a NOS, matched pair of 40's TungSol JAN CTL/6SN7GT bottom getter, round plate(not the mouse ear though) or the Sylvania JAN CHS/6SN7W tall bottle(the short ones are a no no). I'm using one of each in my Cary monoblocks(driver and phase splitter), and the results are excellent. The cost of those tubes has gone through the roof lately though. Very close in sound are the Sylvania and Ken-Rad bottom getter VT-231's. Most of what they give up is in the sound stage department(not much though), and they are a tad less liquid in the midrange(both are much less expensive). I'm bi-amping with SS on the bottom, so I can't give you an honest review of the bass through these tubes, but- the 6SN7W is known for it's "slam" and both of the "Grails" for their microdynamics(which I CAN attest to). I've always done well purchasing tubes on eBay, but be certain the seller knows his tubes, gives comprehensive readings, and the triodes are matched(of course- a high feedback score is a must).

Ok it apears that my amps use two 6ns7 and six 5881. What do I do for the 5881's?

Sorry for slow responce..have been working a little too much.

The 6L6WGB and 5881 tubes are identical(just FYI). I'd suggest contacting Kevin at Upscale Audio and asking his response to the sound of the TungSol re-issue 5881: (http://www.upscaleaudio.com/product.asp?itemid=574&catid=87) I've never tried them personally, but have heard some good things. There are also a variety of NOS 5881's available. If I were looking, I'd try to find the TungSol, or Philips JAN 6L6WGB(probably the best option): (http://thetubestore.com/jan6l.html)
