I just joined headfi for a thread like this. I ordered a Woo WA6 which should arrive tomorrow. I don't know how I'm going to sleep! I already ordered an early 50s Mullard GZ34 rectifier tube and NOS 6GL7s drive tubes. I will be driving Sennheisers (HD598s and HD800s). I'm glad to be in good company!
Welcome - I caught the head-fi bug while living in Chicago. Lots of cold nights for critical listening sessions. You've got some nice equipment coming your way!
