Beresford TC-7520 couple of questions

[scene]

What's the difference between the Beresford TC-7520 and the TC-7510? On the WHFS&V reviews, the 7510 got 5 stars, but on the Beresford site there's no mention of the 7510. There is the 7520, which apparently got 5 stars from WHFS&V, but there's no review of this I can find on the WHFS&V site (or in the mag - unless I've missed it). Is the 7520 just a re-badging of the old 7510?
If not, how does it compare to the 7510?

The 7510 has 2 optical inputs and 2 coaxial.

The 7520 has 1 optical, 1 USB and 2 coaxial.

Not too sure though if there are more differences than that although I think it has improved internals.

Thanks for that messiah. I saw the USB input had replaced one of the opticsls, and I wondered if that was the difference - a little tweak to make it more pc-friendly, but a couple of things I've seen to imply what you said, that it has improved internals. But just like to know if it is as reviewed, or different...
