I understand hearing something that sounds more ‘right’ or ‘correct’ for my music and ears than other things… So let’s maybe start with what it is you're looking for; Something close to the tone of Shindo…
If Leben is close to that, then yes, great sounding unit. I heard the CS600 with Devore Gibbon X and it was wonderful. I dropped in a Vinnie Rossi LIO with DHT and it was just as good and maybe a bit better inca few areas. I now have a Vinnie Rossi L2 preamp (also DHT) and it’s of course ($$) quite a bit better than the LIO… So, DHT’s maybe?
