Tube recommendations for AES AE-3 Preamp


Does anyone have tube suggestions for this Audio Electronic Supply pre-amp? I'm new to tube components, and I realize the perfect tube is always going to be a personal preference. With that said, I know upgrading to a NOS tube will be an improvement to reduce microphonics, and help combat the thin sounding digital music.

I have a tight budget, so any suggestions for 6SN7 tubes on the AE-3 would be great!

Thanks!

Thanks for everyone's input. I found a good deal and settled on some matching NOS Sylvania GTB black plate chrome domes....

Anyone have any experience with these tubes?
Make sure they are quiet. Many of the preamp tubes for sale in cyberspace are noisy.
Hmmm...I would certainly hope they're quiet, but like I said I'm new to tube components so I may not recognize abnormal levels of noise caused by defective tubes. Any thing in particular I should look out for
I have yet to find a chrome dome Sylvania to be noisey.
The EH's on the other hand sang like a bird.

I bought a pair of Sylvania GTB chrome domes from a well-regarded seller on Audio Asylum and in a Cary Sli-80 amp they are very quiet and sound superb. Good choice.
