The problem with people recommending preamps on this site in particular, is that most people have experienced a very limited number of preamps under very limited circumstances.
Especially when you get into a certain level of quality, when the biggest difference between them will be taste and circumstance.
The mid-level preamps will all work fine 98% of the time. Even the cheapest ones will get the job done under most circumstances.
The order in which the equipment affects the sound is this:
1. Instrument and room
2. Mic and the placement
3. Preamp
4. Converter
Now, the instrument and the room will be 80% of the sound. The mic and placement will be 17%. The preamp will probably be 2.5% and the converter 0.5%.
So, if you don't get the instrument and mic right, the preamp and converter can't save you.
With the GREATEST respect Jay, I would put Performer at the top of that list!
