Best Vacuum tube for Bellari VP129

I've currently got a Ruby 12AX7A tube in, but wondered if there was one that would improve performance noticeably?

There are a myriad of NOS tubes, but they are kind of pricey. Try a Mullard CV4004 from Upscale Audio. http://www.upscaleaudio.com/Mullard-CV4004_p_5.html
