DAC volume controls

I'd like to get other's opinions on their experience about using a dac's volume control straight into a power amp instead of going analog into an integrated/pre.   

Currently I have an Aurender A10 and a BAT 3000SE.  The A10 seems to benefit from the BAT's preamp (though I have never had it with just a power amp - the BAT has no pre-in). 

As part of a potential long-term upgrade I am thinking of stepping up to a dCS Bartok which is supposed to have a very nice volume control. 

Thanks.

Many thanks, three_easy_payments.  You are correct, the A10 does not have an analog volume control.

You will receive a ton of opinions on using a DAC’s volume control and pros/cons of having a pre in the chain. The best way is to carefully test it in your listening room. Try each way for a week or so.

I tested using a Linn DSM straight into a power amp and then added a Pass Labs XP-20 preamp and used its volume control. I liked the sound with the Pass better...

It really depends on the implementation. There are more options when you have the opportunity to implement a digital volume control before it undergoes conversion from digital to analog.

Many of the best solutions perform volume control in the digital domain, and certainly when music is being produced volume is being manipulated in the digital domain.

I use a PS Audio DAC senior and use it with it's digital volume control and I love it . As I just listen on phones nowadays the level of detail I get is incredible. Now I know why my millennium born nephew hates it , "too much detail Uncle Jim".

I have Benchmark DAC3 to Benchmark AHB2 power amp.  It sounds wonderful and has digital volume control for digital signals.  Previously I had Benchmark DAC1, that had analog volume control.  DAC3 sounds way better, but it is most likely because of different D/A converter and processing.  Analog volume control over time developed static and I had to lift back of the pot and spray fader lube inside.  I had to do it couple of times.  With digital control it will be quiet forever.
