Filterless DAC - pros and cons?
 
After reading a few articles about the necessity/non-necessity of the post-DAC reconstruction filter, I see that there are two tendencies:
- remove the filter and rely on the quality of the amplifier, and
- use a tube filter

I'm posting this thread after a long debate about this issue. Since I don't have the expensive equipment to test "empirically" the two variants, I want to ask some more experienced people about this subject. Do you think that the filter can be totally removed if the amplifier has low enough IMD?

I suppose you are talking about the analog filter after I/V conversion?
You should have something, at least 1st or 2nd order.
I changed completely the analog filter of my Audio Alchemy DDE v3.0 dac (6th order!:eek: ) by a second order filter and the result was what I expected: amazing.:D
