12ax7 vs 5751

hi all,
i need some advice. i`m very new to tube amplifiers and i`ve been doing some tube rolling.

i currently have a pair of grant fidelity matched psvane 12ax7t`s in my amp which sound fantastic.

what i`d like to know is which are the better tubes, 12ax7`s or 5751 tubes. i`ve been looking at forums and there are folk out there that say 5751 tubes are better than 12ax7 tubes.

can i have your thoughts on this please and also which are the good 5751`s to go for.

i really like the psvanes but if they can be bettered i`d go for it as my next line up of replacement tubes.

my amp is a yaqin mc100b. the tubes i have installed at the moment are.....
2 x psvane 12ax7t`s
2 x brimar 6sn7gty/cv1988`s
2 x sylvania 6sn7gtb`s
4 x electro harmonix kt88eh`s

many thanks in advance guys.

GrayF, yeah, sell me the Slyvania 5751 and GE pair, that way you replenish some of your investment. That is one of the great pleasures of tube rolling, you can usually recoup some of your money if a certain tube doesn't work out.

mikirob, the ge`s are definately not right. i put them in when i tried out the telefunkens. when i switched the amplifier on it sounded like distant thunder rumbling. i put on a cd and again i got that distant thunder sound so i took them out. they sounded really nice but that rumbling left me feeling a little uncomfortable. i had the same thing when i had the electro harmonix kt88`s in my amplifier too with the ge`s. i actually did think it was thunder in the distance!
