A little off topic, but I'd like to make a few comments on the mixed impressions of the HE-5's here. I've had a pair of these almost a week now, and so far I'm very, very impressed.
As Wayne mentioned, his pair had essentially no break-in time. These don't appear to need a lot of time, but they began to improve after about three hours and were much better after about ten.
I have an amp that is very similar to Collin's (triode wired 7788, spud configuration, Electra-Print output transformers). Based on this thread, I chose this amp for the first few hours of listening. Very nice, but at 1.25w maximum, a bit underpowered for the job. The HE-5 is not a power hog like the K1000, but it definately needs more than the usual headphone. After the 7788 spud, I switched to my big GM70 DHT amp (Vicki- it still exists and you will see it again). Major improvements all across the board. I've been around audio most of my life, and in general I'm a sceptic and a cynic about the latest FOTM. Properly amped, these are wonderful headphones. Next meet you guys have, I hope someone runs them off a Moth, or some similar small DHT based speaker amp. I think you'll like what you hear.
