I'm now super happy with the sound quality as I get deeper into my music collection. The lesson I'm seeing is that this player sounds very, very different depending on which output you choose, filters, etc. The high output impedance presents some challenges in matching (or opportunities I guess, depending on your perspective) We all have different tastes, and different ears, but for my tastes and my ears this is a clear upgrade over the SP1000. I will still be trying it against the 2000 soon.
But at the price I believe this is a very good value and a very enjoyable listen.
