Well, I used a fairly eclectic mix of tests: Newton Faulkner - Hand built by Robots, Eric Clapton - Journeyman, and the Vivaldi Stabat Mater - Academy of Ancient Music (Christopher Hogwood).
Considering I hadn't used the headphones for probably 20 years (I bought them new from Audio-T in London in the late '70s whilst I was at university), they sounded pretty damn good. Thinking about it, I'm sure I've not used them since we have been married, so that means since late '80s
They are punchy, have good imagery and dynamic range. They sound clear and clean, and pretty free of artefacts. I like them.
Main issue I have is that top-end punch is a bit weak - I suspect that this may be more to do with the SM2 pre-amp than the Beyers, so I want to dig out another pre-amp, although the SM2 is the only class A pre-amp I have.
I have full faith in the Perreaux 2150B - its an amp I know intimately and I've measured pretty much every characteristic I can of it - whilst its not a Doug Self "Blameless" amp, its not bad - I rebuilt both it and the SM2 from destroyed wrecks, so I am aware of the SM2's shortcomings...
The KEF XQ-Fives are a good comparison - whilst they are reasonably current and fairly expensive, I think they Beyers do pretty well up against them - some of my niggles about the ET1000s can also be heard on the KEFs and that's why I have minor reservations about my test signal path..
Cheers for now
