Diehard Sony Fan, always wanted to get both of the Z1Rs, finally pulled the trigger last week(along with the FIIO K7). The FIIO K3 will be paired with the IER-Z1R. The FIIO K7 will be paired with the MDR-Z1R. Wanted to get the TA-ZH1ES, but currently out of budget.
My 1AM2 and N3AP can finally retire.
As a new owner of a Walkman (Japanese ZX707), I was wondering why you were retiring your high-end Walkman and buying DAC/amps when your Walkman could have driven both of those headphones/IEMs just fine. Then I realized that in classic Sony fashion, there are two products in their catalogue that both end in "1AM2": there's the Walkman NW-WM1AM2 and the headphones MDR-1AM2. I presume you are retiring the headphones?
Naming collisions aside, congrats on the purchase! I may be joining the MDR-Z1R club soon!
