Thanks, that really good info! Lasty night I realized that my Q701's are on a different level from the PLYR1. I mean, obviously, right? But yeah, it's just so obvious after playing with the PLYR1 for a few hours and then switching to the Q's. The soundstage is MASSVIE in comparison, the details are more defined, etc.
I'm still waiting for my X1's to arrive (damn you, international shipping!) but in the meantime, I'm falling in love with my Q's. I would love more bass, of course. Evshrug suggested that a tube amp could help bring out more bass without sacrificing what makes the Q's special. I was looking at maybe cheaping out and getting a hybrid Schiit Vali. You used the E12 with yours?
I still think the PLYR1 is great for an all-in-one combo that's just easy and simple. They're no longer on sale for $130 so they're harder to recommend for $180, but I don't dislike them.
