George (gtp) discovered that both of us worked in Goleta. So today he met me at my office for a quick mini-meet. He brought his DT770s and some music. Mostly he had the chance to get his first listen to tubes with my SLAMM PPX3 and to listen to my K340s. He seemed to like them though I'll let him tell what he heard. I've been considering a complement to my Headphiled K340s. From the descriptions, a pair of Darth Beyers may be what I want. So it was a treat to listen to George's DT770s. I can't imagine headphones more different from the K340s than these. The bass was extraordinary but the mids and highs just couldn't match the K340s. The sense of "being there" wasn't there. I've read here that converting them to Darth Beyers fixes a lot of these problems. However, I need to hear a pair before investing $500-600. I guess now I'll have a reason to come up to SJ for the International meet next year. Just for reference, my SLAM PPX3 has a pair of Tung Sol D-gettors as output tubes. We listened with an unknown loctal pinned 6sn7, a Sylvania 7n7 tall bottle and an RCA 6cg7 black plates as gain tubes. We both preferred the 7n7 tall bottle.
