I use a Raven Labs headphone amp or my computer (either built in or with a Metric Halo interface. Great headphone amp and one of the best DIs there is). Headphones these days are Sennheiser HD600 for open and Audio-Technica ATH-M50s for closed.
On the Eden thing, I'm done with that company. My third Navigator broke down (the output went low, I know it's just a couple of JFETs, but I haven't fixed it yet), my WXT500 blew up on the first note of the first gig as did my WT1205. The former was replaced at the store where I got it. The latter was used and has spent the last 14 months at a Denver authorized repair shop. They finally emailed me a couple of weeks ago and told me they were sick of looking at it, so they UPS'ed it to Eden on their dime. Not a cheap prospect. So far, Eden (aka American Music) has ignored phone calls and emails. So, $1k down the drain. Ugh. I never liked the speakers much. I had a pair of the 210XLTs back in the day and went back to Acme pretty quick. These days, I replaced the Navigator with a Grace M103. Fantastic tone and it will never break down. With my F2B ahead of it, it's the best of all worlds.
