I guess I'm not done with my rant.
What do we want a prr-pro to be ?
For me it needs to be the heart of my systom, able to accept whatever I throw at it and give me what I chose in return.
It needs a good analog section, though turntables could be supported by an outboard phono section.It needs great DACs,though again, Direct stream Digital and the like might be handled externally. In the current era, it also needs great video prodessing.
It should probably have both un-balanced and balanced ins and outs.
It should probably do a very good job with room correction/equalization, distance correction and bass management.
Wi-fi connectivity ? mabey.
So what else should a pre-pro do?
