I have recently bought the Bushmaster Mk11 and can now sell my 7520. It's had loads of mods done to it, all by Tirna Electronics. The most important are:
Wolfson dac chip (Caiman)
Gator board
Upgraded op-amps
Most caps replaced with Elna Silmic 11's
Lot's more information here:http://theartofsound.net/forum/showthread.php?19496-Beresford-Mods-from-the-Drawing-Room
Personally, I think the SQ is not far from the Bushmaster but has the advantage of having fixed and variable outlets (preamp function) plus USB input so it is a more flexible piece of equipment. I would say that the Bushmaster has a better headphone circuit so if this is important to you don't buy it.
I reckon, in addition to its original cost about £150 has been spend on the upgrades. I am asking £80 plus £5 for p & p in the UK.
