DAC as pre amp


This post is just a brief for posterity sake in regards to the the significance of a good pre.  As I have stated in other threads over the last few years , when the subject arise,  I occasionally remove my pre from the chain and run my Wadia 321 as the pre.  I always find my way back to my dedicated pre.  I got some Quad Z-4s awhile back and after a recent post regarding the DAC direct question I decided to try again.  This round the improvement was even more dramatic with the dedicated pre and the Quads. My modest system is good enough for my level of listening sophistication.  but If I ever decided to upgrade a component in the future , the pre would be the unit I would explore.   Another member stated that a good pre will ad a "richness" to the sound.  I think that is exactly what I hear.

So you enjoy the coloration provided by the Pre.

It’s more likely that they enjoy the improved performance due to better impedance matching, a better output stage, and better ability to drive an amplifier. I’ll think you’ll be standing alone in this line.

So an integrated amp is a bad idea to? This may not a good way to think about preamps but it seems to me if you stay with the same brand the synergy should be there…there’s a lot of convenience using a preamp…turntable, cd player and two dacs hooked to mine…

‘I definitely would like to hear more on this subject…

@soix  My DAC has at least twice the signal boost of the preamp and I have tried using the DAC to biamp directly to the speakers with acceptable results. However like others I find using a preamp gives a richer sound but there is not a lot in it and if anything omitting the tube pre gives a quieter darker background.

Uh.  What?  You use your DAC to bi-amp speakers directly?  What DAC/amp exactly are you using?

There are exceptions to the rule for example the Excellent T+A 200 dac- preamp 

is a true dedicated pure class A preamp with a discreet output stage and galvanic isolated ,and that’s built into this fabulous dac ,I have heard this running a nice 

Custom SET Tube amp, as well as a Pass labs amp and sounded excellent 

vs several $5-7k preamps that is saying a lot.
