I think I finally may have curbed my desire to upgrade or try other headphones or amps and such. Lately I've been obsessed with expanding my music collection and I've been buying CD's like crazy. I'm finally happy with what I have and have now made it my goal to just keep expanding my music collection. I've also been going back and ripping my collection in ALAC instead of high bit rate AAC or MP3 because with the setup I have now I feel that I finally may be able to tell the difference. I am also no longer buying my music from iTunes, I want to have the physical copy so I can rip it in ALAC.
I am very happy with my modded Q701 and my whole audio chain.
I haven't had any real interest in trying new headphones since I got the HD-650. With the HD-650, DJ100 and Q701 I'm set for a very long time. I think this is the longest i've gone without buying any $100+ headphones.
Once I modded the Q701 I decided to spend money on a new amp for it (bedroom use) about a week later. Since that didn't work out I bought a new DAC instead. I think so far i've been through 4 different DACs just for the Q701. Probably even more amps!
Went with the Headroom Micro DAC. It'll be nice having optical, coax and USB input AND not having to rely on USB power.
If this DAC is good i'm retired from any gear changes for as long as possible. Modi is not going anywhere.
Still curious about the K712 but there is almost no chance i'll buy it. I'll STEAL IT! Just kidding. I only paid $235 for my Q701 so $350 for some (possible) minor improvements isn't such a good deal to me.
Had this Q701 since Oct 2011 already. Not even sure when it came out. I haven't owned a K702 since 2010.
Would like to try some K712 pads on this but it seems I can't do that unless I want to accidentally get Annie pads again (Which I hated). Same part # I believe.
