Impressions-
HE-500: Good bass and clarity. Much more enclosed soundstage than the K702’s. They do everything well, but there’s no wow factor. I want to be excited about my headphones. There were no goose bump moments with these cans.
T1: Much like the HE-500’s they did a lot of things well, but were not terribly exciting. Better soundstage than the HE-500’s, but not as good as the K702’s. More mid emphasis than the HE-500, and less bass extension.
HD 800 (Anax mod): Listening to the K702’s for the last year has turned me into a soundstage junkie, and these were the only cans that really fed my addiction. They were very spacious and incredibly detailed (revealing). They had more bass than the K702’s, but not by a lot. However, even with the Anax mod, there were parts of some songs where the treble made me wince. This was especially noticeable with Tori Amos and the banjo from Punch Brothers. On the right system, the HD 800’s sound spectacular and do not have this problem. They sounded particularly good on the TTVJ Pinnacle, FrankCooter/Ironbut’s tape system, and the Balancing Act.
LCD-3 (TP mod): “Musical” would be the best word to describe these. Larger soundstage than the HE-500’s and similar to T1 (maybe a smidge smaller). The soundstage didn’t sound enclosed, it sounded intimate. Every song was completely engaging. The bass was outstanding, but the overall tone was a little on the warm side. Of course, these sounded better (much much better) on Frank’s system.
LCD-2: Same magic as the LCD-3’s, but slightly less. Everything the LCD-3’s did well, these did well, but to a marginally lesser extent. Enjoyed listening to all my tracks. Not as revealing as some of the others, this is good thing to a certain extent, given my system. It is hard to justify paying $1000 more for the LCD-3’s when these do nearly as good a job.
Magnum (V4): Surprisingly nice. Airy and detailed with great mids. Enjoyed the Smashing Pumpkins track with these. If you can get around the Grado comfort issues, these are a great lower cost option. I can’t get around the Grado comfort issues.
HE-6: I know that the Lyr is supposed to be able to handle the HE-6’s, but I had to crank it up all the way for the Rachmaninov track. Maybe there’s not enough juice coming out of my DAC.
Of course, these are just one person’s opinions about how these headphones sound on his system with his music. YMMV. Thanks again to everyone!
