... For the most part I think if you aren't spending over a grand, including interfaces you will still need a separate pre of some sort to get pro quality. ...
"Pro Quality" these days has a lot to do with UI and incrementally better electronics. The difference classically was much greater on paper than it is today. Out side of the top ranks most recorders are probably using the same converters. The clocking will be more stable and the analog section will be quite a bit better in the mid and up range. That can make a big difference but nothing like the difference between a cheap consumer cassette deck and Nagra was a few years back.
Because of this "pro quality" output is more connected to the sound person than it was. Use a decent preamp and you can go into almost any of the cheap recorders and get a file that people won't know was done on a cheap POS recorder. But the difference between having someone who knows what they are doing recording VS some inexperienced operator is still huge.
The point is getting XYZ recorder is not going to get you "pro quality" tracks. Going out with whatever recorder you have and getting experience will help, working with a pro for a few years will help a huge amount.
It's what marketing types keep trying to hide but the reality is you can't buy experience you have to earn it.
