Tube favorites for Modwright LS100?

Howdy Friends,
Are any of you having success with a little tube rolling for the Modwright LS100 preamp...either the 6SN7's or the 5AR4? And I am sorry, but I am not interested in anything costing dern near as much as the preamp itself...$500 or more for a pair of vintage 6SN7's? Not happening in my monetary (read "happily married") world.
Thanks to one and all for your kind input and experience!

You could also try some Sylvania 6sn7 "Bad Boys" or some of the early 1950's Russian (Sovtek) 6sn7 with the metal base.

I agree that the new production Tung-Sol's are very nice.

I've had my LS100 for about 18 months now. It does require 400-500 hours to fully break-in.

I would really recommend that you swap out the rectifier and the 6SN7 tubes. I have tried MANY different tubes and found the Shuguang Black Treasure CV181 and the Mullard 5AR4 to be the best FOR ME. The Sophia Electric 6SN7 tubes are really nice also.

So, between full break-in and new tubes, I'm pretty sure the LS100 will be what you are looking for. Of course, I'm biased because I LOVE mine!!!!

There are several threads here on Audiogon and on Audio Circle that talk about tube rolling in this unit.
