man, when i was selling 12v stuff back in the early 2000's, the kenwood menus were so counterintuitive and just backwards feeling whereas the pioneers were the exact opposite. The kdc-x959 vs the pioneers or even the alpines of the day of the same level quality were a nightmare to set up. I cant remember the model numbers of the pioneer(maybe deh-p3600), but the alpine of that day on the same level was the (AWESOME) CDA-7998. That thing was a beast and easy to navigate the menus on
i had a deh-p350 back in the day and loved it!! It was part of the Premier line, still have no idea what the differences was between those and the normal ones, but i thought i remembered mentions of the DAC being better in the Premier ones
