Sony SCD XA5400ES tube rolling?

Ageed. The Truth umbilical is a MUST to bring out its full potential. The stock umbilical is for the birds. I have the Modwright tube Oppo and also use a nos Mullard rectifier tube.

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.

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.

Well the Sophia's arrived yesterday and I popped them in and noticed an increase in resolution, a wider soundstage and more 3D. If you are looking for tubes to add warmth coloration- look else where. These tubes are very neutral and linear. I also notice a subtle tilt toward the treble and other reviews say this will resolve itself as it breaks in (up to 300 hrs). Even with that, I like the Sophia Electric sound better than my nos Sylvania's in my Modwright Oppo 83.

I'm glad I tried these. Thanks for the recommendation!

I was wondering the same.

FYI, for those interested in giving these a try, there is a pair of Sophia Electrics sitting in Audiocircle forum for sale with only 6 hrs of use for $150.

I have no affiliation with that sale or with Sophia. My only connection is that I'm a satisfied customer :)

Knghifi- I'm definitely interested in hearing about your findings.
