After looking around for a complimentary pair to my HD800S that might also be an upgrade from the HD650, these have caught my attention. I can listen to the 800S all day long on my setup, and I don't want to replace it, but sometimes I want a bit more quantity in the lower-end without losing too much resolution like I do on the 650. I'm torn between this and the LCD-3, but also looking at LCD-4, and considering the stratosphere with the 1266 Phi TC (which would very likely require a new amp, and total cost would be multiple times the Z1R). The Z1Rs definitely look to be the most comfortable out of the lot which is a big plus. The 800S and Z1R seem like a good duo to have on the desk to switch back and forth with for differing traits. Is the Z1R what I'm looking for? Chain is fairly warm and smooth, Directstream Jr. dac (Qobuz or CDs) > HDV 820 amp.
