My new Q701 and Lyr 2 will be here tomorrowreally excited! I really loved listening to the K701 and original Lyr at a meet a few years back and glad to own it's brother. It's funny, there are so many headphones out nowadays but I remember starting my journey 8 or so years ago and admiring what seemed to be two of the best headphones in the world at the time, the K701 and HD650. I used to wonder to myself, "Those two most be a glorious euphonic experience to listen to...I wonder if I'll ever get to experience that." And now even though its the Q701, in my eyes I've fulfilled that dream. Maybe the Q701 isn't my ideal sound signature but as a collector, it has great sentimental value.
Anyway, really can't wait to get home from Uni and try all my new gear out (including an HE-500).
I think you'll really like the combo... I've got the Q701's that used to be made in Austria so not sure if there is much difference to current models. I also have the Lyr1 but also assume a similar profile as well. The best investment I made was going to the tube rolling threads and tracking down the holy grail tubes. There is a user that sells them on this forum and they were night & day difference in the sound.
