I'm looking for a preamp with the following characteristics: 1. must be stereo i.e two channels - no more, no less 2. must have digital out 3. must not cost more than approx $1280 / 700 pounds / €1000 4. must not cost less than approx $400 / 210 pounds / €300 5. must not be made by Behringer I've narrowed it down to the following: a. Focusrite TwinTrak Pro b. ART Digital MPA c. DBX 386 Silver Series d. MINDPRINT Envoice MK II e. PRESONUS DigiTube (I would buy two) f. SPL Goldmike MK II g. TL Audio 5060 Ivory II Which one has the clearest sound quality? Can you think of any that aren't in the list that fit the bill and that you would recommend? I have to narrow this down to one before the weekend. I'm grateful for any advice. Thanks.
