You might want to try a lector zoe (easy tube rolling). I used one with my magnepan 1.6 speakers and they added the correct missing tonality for many instruments. I believe you need tubes somewhere in your front end equipment. I'm sure other fine tube pre amps will also work well.
Preamp for magepan 3.7 and Sanders amp combo
Currently have an older Audio Research. L's15. Looking for a nice upgrade suggestion. Think tube pre might be the way to go. If you were going to a newer ARC model and price was an issue where would you suggest? The Refs are out of my price range. La26 or 27? Thanks for any suggestions.
