Brimar vs Mullard cv4003/12AU7

Has anyone heard these two NOS tubes pitted directly against each other.  The virtues of the Mullard are well documented; certain sellers (cough, Upscale) praise the merits of the Brimar to the heavens, and they *are* considerably less expensive.  Thoughts?

A Mullard in the right circuit can sound holographic.
Hello, Mullard Man here.  No comparison, (in the right circuit).  The Mullards are hard to beat.

I've not tried the Brimar's but immediately chose the Siemens E82cc/12au7 over two different Mullard's, including the CV4003.  I also preferred the Siemens over the Radiotechnique 12au7.

Call Andy at Vintage Tube Services and ask his opinion on the Brimars.
