Nu-Vista question

Are there any Nu-Vista owners out there who have tried, or have found out if a Nuvistor 7895 can be sub'd for the standard 6CW4's in Musical Fidelity Nu-Vista gear - and most specifically in the Preamp?

If so, are the results favorable, nuetral, unfavorable?

thanks in advance . . .
