Sony SCD XA5400ES tube rolling?

If you read the posts carefully you will see that the Mullards and Sophias were recommended by Dan Wright. This is not a case of second guessing the modder. It is a case of taking his recommendation on cost no object tubes. I am thoroughly impressed by his work and because of that, would willingly accept his advice on tubes, cables, power treatment, feet, or anything else that he wants to comment on.

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.

Hey thanks for the helpful feedback guys(and to those who will post). @Rhyno & Erndog, yes I opted for the umbilical upgrade..no deliberation there. I also noticed Dan's comments regarding the Sophias. IMHO, he probably decided what's the best stock tube at a certain price ($20)each. Using the "Sophias A's" as stock, would have raised the price of the upgrade by $200.

For once, it's cool to see different results using different tubes. For solid state one is 'locked' into a certain sound and then having to live with it (playing with cables then I guess...). Judging from the reviews on the Sophias, most are using them in their preamps (and getting great results).

Brimar 6NS7s (cryo'd for me) are the best 6ns7s I have tried after some experimenting. I got mine from Brendan at Tubeworld, who recommended them to me. Nice and warm and resolved and evenhanded.

The NOS Sylvanias Chrome Domes are mucher better in my system than the Sophias, better seperation, sharper image, deeper/wider soundstage and more ambiance at a much lower price.
