Man you got all the good Jessicas'
Are you still running the e17 as a DAC for your main setup? I'm currently on the e17/e09k setup. It's solid (no pun intended), but I'm considering the upgrade to the Lyr, but hoping that i might not have to drop the large dough for the bifrost. I figure changing the e09k to the Lyr would be more cost effective than changing from e17 to the Bifrost?
You can do what I do is get a fiio L7 (its pretty cheap) which will give you a line-out (lo-bypass switch on the side needs to be set) and use it as a DAC with the lyr until you can afford a bifrost.
I would have offer another opinion here. I owned the he500 and now own the hd650. They have a different presentation so it depends on what you are after. The he500 have some of the best mids in it's price range, but actually I prefer the mids of the 650. The he500 is technically better but I found myself reaching for the 650 time and time again until I sold the he500.
Please understand that the he500 is a great hp. I really do love the planar sound. But if I were going for an open planar, I'd pick the he400 as it adds better bass response and is very close to the he500. The other issue with the he500 is the weight. It's heavy...at least for me. The 650 is about a third of the weight and infinitely more comfortable.
Couldn't agree more!
