need tube advice from tube preamp owners.

You are really putting the cart ahead of the horse. Let your new pre-amp break in first then listen to it carefully for a few months and decide what about its sound you would like to improve, then post a question like "My pre-amp has rolled off highs (or bright highs), what tubes could I change to get a better balance" and what brands would you recommend". Then you will get a meaningful response. Otherwise recommendations are a WAG.

for very detailed comparisions of the sound qualities of various NOS tubes, check out Joe's Tube Lore at the tube forum on Audio Asylum.

newbee, im not looking to correct a problem that isnt there all im lookin for is advice on some good preamp tubes maybee even from a c2200 owner who has tried a few.

whats wrong with hearing differences in a preamp right from the start & making choices as to what sound i like the best.

from the little tube experience ive had with my mc2102 & c20 preamp i know a good tube makes the unit take on a entirly different feel & thats what i want to explore right from the start.

Take Newbee's advise, you need a base line for reference to start out, otherwise you don't know what you are comparing against.

thanks swampwalker, thats just what i needed.

i dont get it? really i mean i dont get it, if i swap out the gold dragons that are in my dac for some telefunkins i hear a difference right off the bat & i mean instantly.

while i admit i know almost zero about tubes i still have no idea why i need to listen to one certian tube for months before checkin out another,what base line do i need to hear.

to me swapin out a set of tubes is very little different from adjusting treble or bass or even changing a setting on a equalizer.

can somebody explain the benifit of listening for months.
