Very pleased with mine and I've taken it to a different level with Burson OpAmps installed into it -
AudioUpgrades. You don't need to go the whole hogg with their upgrade path, I had a semi-level 1b costing £155. AudioUpgrades reckon the Burson's take it to a £1k plus DAC level!
The beresford DAC may prove a better option as it's cheaper to start with, not sure if the Burson's fit in it though, speak to Brent at AudioUpgrades, he's very helpful.
Interesting, I would love to know if they do fit the beresford. Looking at this link: http://www.audioupgrades.co.uk/burson.shtml those ops are massive, so even if they were compatable, I dont think they will fit it the casework without some modification.
I will email Brent on the matter and see what his opinion is.
