can you recommend any two channel units ? What do you think of the Tascam's built in A/D ? The needle drops I have made lately sound really good. Is mytek's a/d better than the DA-3000's built in a/d ?
Yes, the Myteks are better than the internal A/D converter but it's not a night/day difference.
At this time, there are only two 2 channel converters I can recommend. That is the MSB Platinum Studio and the Ayre QA-9. The 8-channel converters I can recommend are the aformentioned Grimm and Horus.
