Sony SCD XA5400ES tube rolling?

Just got my player back from Modwright,fully modded with the ultimate upgrade. Wow! incredible difference over the stock player even cold out of the box.

Now the question, anyone have experiences with tube rolling with this player? The stock Russian Tung Sol 6SN7s are supposedly fine, but I decided to order some KEN RAD WWII military (VT231)tubes and see if there is a big difference in sound. In the mean time, awaiting their arrival... comments are welcome.

i have been trying to find a reasonably priced pair of brimar 6sn7. i use some older brimar 12at7 and 12au7, so i would like to try brimar 67n7, circa the 50's.

i think, unfortunately, you will need to spend some money or borrow some tubes, try them out and decide for yourself. the age of a tube is important as is is its manufacturer. there are other factors as well.

no one can predict how you will the sound of a tubbe. just experiment.

if you lived near me, i could bring several pairs of 6sn7 to you to try.

i'm buying a pair of rca grey glass from the 40's.

while i would prefer the brimars, they are hard to get and very expensive.
