I'm using the Mullard CV4003 and I was about to buy a backup when I thought I should check for a better Mullard 12AU7 version so I can use the better version and keep the CV4003 as the backup. Any recommendations? Are the M10 or the CV491 better than the CV4003?

The 1950s long plates are my favorite Mullard 12AU7s.

Have you tried Telefunken ECC802S ? Wow!

If you can't get the 50s long plates which are rare, try for Mullards Blackburn coded with non military Mullard logos. Your best bet is to use a good vendor/dealer, although their services for that tube will be costly. Check some threads for suggestions for dealers,
If you want a Mullard like sound consider the Gold Lion Russian tube.
