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 just read the exceptional (balanced, informative, non-hyped) review in july Positive Feedback. Where is best source to buy mullard and sophia tubes, and for a tube rolling neophyte is there a particular version/flavor/spec of those i should gravitate to or from? Thx in advance.

I bought the NOS Sylvania Chrome Dome Bad Boys. Didn't even make it into my Sony player yet because they took a detour to my VAC 300.1a amp. Holy Toledo! They sound awesome. Added some heft, low end energy, space that wasn't there before. Now I need to find two more for the Sony!

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 agree with Erndog's assessment. I put two Sophia 6sn7s in the Modwright 5400es. I noticed more depth/3d and a "smoother" quality to the sound which allowed more details to emerge. They beat a pair of chrome domes I was using.
