Ain't that more likely just for the WM-1 A&Z Mk2 Walkman? Sony did join Canjam for every signature series, back then with the full suite of MDR Z1R, DAP and Dac/amp, again with IER, heck they even joined RMAF for the SA-Z1, they knew where we geeks gather and we're squarely in the bullseye mark for their products.
On that note the MDR Z1R has definitely become my favorite audio gear for music listening. The Synergy it has going with the WM1A is the final icing on the cake, nothing else I own (other than the IER) make me feel as satisfied, it feels, complete.
My T1 still serve as my daily, gaming, movie watching and what not, but IMO I don't really like it as much for music listening. Besides, I'd rather spare the Z1R only for special occasions.
The only regret I have is that I couldn't try driving Ananda with it as my pair's R side died due to Micromold a short couple weeks ago.
Do you listen to jazz genre? I wonder how do you compare your Z1Rs with your Z7s for that specific genre (my preferred genre with the Z7s).
