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.

Well, I decided to hear what all this talk about Sophia Electric is all about, so I ordered a pair- should arrive on Sat.

I also want to add that I'm Very satisfied with my current tubes in my Modwright Oppo 83, which are nos Sylvania 6sn7GTB yellow label from the 1960's. It's going to take some over the top tubes to best it. We'll see how the Sophia's perform after their 300 hrs of break-in.

OK, I'm ordering some Sophias. Fortunately, I have 4 6sn7 tubes in my VAC 300.1a amp, so am able to roll same tubes in there. Since the Sophias are so closely matched, I could use them for the input 6sn7 tubes in the VAC.

I'd also like to hear from those who are pulling the trig. on the Sophias and how they sound against the best of the NOS 6SN7, VT231 and so forth brands.
How do they sound against the beloved Sylvania "Bad Boys" or the 'Holy Grail' TungSol's?
This should be interesting..

thanks again guys!

My $80 1960's Sylvania chrome dome are flat out better.

Wig- That doesn't surprise me. The Sylvanias sound amazing in my rig too and I don't see how a new production tube could sound better. I'll post the results of this shoot out.
