Tube rolling signal tubes on Audio Research I/50

I just got an Audio Research I/50 integrated.

Sounds great with Sonus Faber Olympica I's

With Focal Kanta's sounds a bit bright.  Not surprising as the Kanta's are a bit bright and the amp is pretty neutral, but I  have preferred the Kanta's with other amps. (Raven Audio Osprey and Blackhawk)

Has anybody tried tube rolling the signal tubes on the I/50?

Did it make any difference?

It comes with 6922 JJ's.  I have tried JJ's in other amps and while they were ok vintage tubes were MUCH better.

 

Thanks

I don’t roll tubes on my ARC stuff, because the sound is crafted to be, well, that sound with those tubes (carefully tested to meet specs). Having said that, I look forward to hearing what you find, 

I did try NOS 6550 on my ARC preamp... the difference was very subtle... ever slightly more musical. But that is a power supply tube.

More to discover
