Dear Sony, I love this player, thank you for making it. I use it with your Kimber cable and XBA-N3AP and cannot be happier save for 4 things. 1. Please can the next firmware have an option for Right/Left channel swap? Rationale: Increasingly in classical orchestral recordings the bass/cello section is in the middle, but there are still those recordings which persist in placing the cello/bass on the right. Therefore, my right ear gets lovely low-end and my right ear misses out. You may say: "swap the earphones, or swap the cables" - however, with a premium product like XBA-N3AP etc its not ergonomic or possible and always changing the MMCX connections can cause damage in the long term. Therefore, please provide an option to swap audio channels in software. 2. Option to set a default delay between the end of one track and the start of another. When I'm listening to classical suites/sonatas/quartets/symphonies etc its nice to have a few seconds between the movements. Perhaps this might affect battery life or the capacitors, but if not, it would be nice to set a default gap between tracks ranging from 0-15 seconds. Please could you implement this? 3. In some cases, the end of one track is to lead directly onto the next track (eg. from Beethoven's 5th symphony between the 3rd and 4th movements, or Beethoven's 5th piano concerto between movements 2 and 3). In these cases, it should be possible for the user to specify a custom delay (or none) between tracks which is different from the default. 4. Improved battery longevity - I wish the battery didn't die out after a published 500 charge cycles. I understand its not easy to replace and must be sent away to a service centre. I'd like to keep this device for a lifetime, but the battery element is problematic. Please can you research an alternative battery which has greater longevity? I love this player all things said and the above would make it perfect.

i have changed laptops and i cant seem to connect the walkman to my new laptop to download my music.

[This review was collected as part of a promotion.] I bought this for the sound quality and it delivers perfectly. If you match it with appropriate headphones - it really is first class. I dropped a star because the charging cable is uniquely Sony and if you travel its an additional cable to carry. Also, the software is "okay" but feels a bit clunky
