Title: Quickie As Dac Output Stage
Post by: Jazziz1 on September 20, 2014, 11:34:13 AM
Hello All:

Was wondering if Quickie pre can be wired directly to output of dac chip from cd player, bypassing the opamps? Thanks.

I don’t see why not. I did something similar a while back with a DAC stage in a CD player. It worked great.

Yes, it can.  Whether it will work well or not depends on how much gain was being delivered from the opamp in the first place.

How you do it depends on the particular DAC chip; some put out voltage and others put out current. I googled "DAC IV resistor tube" and got a lot of hits that looked relevant. (IV is short for current-to-voltage, if that makes more sense.)
