On pre90 you can select rca output, xlr output, or both at the same time.
Thank you very much. This is in my opinion a very important feature and I appreciate it being there, even though I personally do not need a pre at the moment. On the basis of how your NCFA circuit works, I now know I can recommend it to anyone that is shopping for a preamp.
The 768khz issue seems not fixable. D90 can play 768khz without issue here. But some users have the issue. And frankly who really needs 768khz...
I know, it is just because I am a bit OCD and I do not like that there are bugs, but of course this is not an important one. 768khz is in my opinion useless. Pass this on to the team that developed the D90 (not sure if you were involved or not): that little thing sounds just great. And the combo D90+L30 (I know you are the mastermind of the latter) is simply lovely with my AKG K812. Congratulations.
