12BZ7/12AX7 vs. 5751

I have a Cary V12 with 12BZ7 tubes in the input. I read an article last night that suggest that the 5751 is interchangeable, just with less gain, and that it sounds significantly better. Has anyone used a 5751 in place of a 12BZ7, or for that matter a 12AX7, and could you comment on any differences/improvements in sound?

Thanks!

As a retailer, I'm sure you'd think so.

Sam, thank you for the backup. Clearly one of those salesmen who wonders why he never sells anything.

I went to my favorite secret old TV store with thousands of tubes lying around looking for a pair of 5751s, but he didn't have two. However, he did have an NOS pair of GE 6BQ5s which - probably because they're fresh - are a bit of an improvement over the old Mullard EL84s. So... you never know what you're going to find.
