Once burned in, they sound exactly the same, that was the whole point when Sony designed the ZX300 in the first place.so now I bought the WM1A. I going to put the ZX300 up for sale.
surprisingly ZX300 and WM1A is very close in sound quality, and similar too.
The SE output sounds noticeably worse on the ZX300 before burn-in than it does on the WM1A in the same conditions though, once the burn-in is done however you will be hard pressed to notice any difference on either outputs between the ZX300 and the WM1A.
The balanced output before the 200hrs burn-in sounds the same as the one on the WM1A with a similar amount of burn-in.
Once the burn in is done on both units, they will sound the same provided the WM1A is on firmware 2.00 or higher (Sony has made changes that tweaked the sound signature in firmware 2.00, the changes were already made on the ZX300 1.00 firmware so there is no way to go back to the "older sound" on those units)
The advantage of the WM1A over the ZX300 are:
1. The screen real estate
2. The more premium look and feel
3. The extra 10mW power output on SE and extra 50mW powwer output on balanced.
4. The extra 64GB of internal storage
5. You can have a different sound signature if you downgrade the firmware to a version lower than 2.00 (some like it, some don't)
The ZX300 on the other hand has the following advantages:
1. Lower MSRP
2. Smaller footprint/form factor
3. Lighter
4. Has the built-in DAC feature
If you want a different sound signature, (not a better mind you, although opinions are subjective), you might want to turn to the (much more expensive and less portable) WM1Z unit instead which sounds warmer than the WM1A giving it a slightly more "analog feel", that said, the WM1A is brighter than the WM1Z, so it's mostly all about your preferences and how deep your pockets are.
