Who is using their DAC as a preamp?

George has been saying all along, that with today's digital sources, with the lower impedances and 2 volt outputs, the gain stages of preamps are not necessary. I do concur with these findings. 25 years ago, or more, there were passive units available, or preamps with passive as an option ( I owned most of them; PSAudio, Superphon, Mod Squad, McCormack, and many more ). Passive was ok, but back then I preferred a preamp. It is interesting, that I own my 2 older Dacs, since '95 ( Adcom and AA ), and not until I bought ( for shits and giggles ) my 1st Nuforce STA200 this time in '17, did I realize passive was the way to go. As it turns out ( and I know Georgie is very critical on the impedance matching thing ), every power amp in my " still " collection, sounds better than I ever remember then sounding, without a preamp between the dacs and the amps. I have several tuners, and other sources that are just fabulous through the amps directly. And this cheap Douk Audio piece, is killer, for 40 clams. I am told by many ( people I personally know ), that George's LDR unit is the best there is, and I do not doubt it. Anyone today who prefers a preamp, imo, likes a bit of color, and whatever else the additional gain stage adds, or subtracts, or, their source is simply inadequate to drive an amp. Just my take on things. Still, no right or wrong; just go with what your ears tell you. Sorry for the rant, as my testosterone levels are high this morning / early afternoon ( which is good at almost 65 years of age ). Enjoy ! MrD.

I have a T+A DAC 8 DSD.  It has a fully discrete, analog volume control that even uses a vishay resistor ladder.  My preamp is the Perla Audio Maestro which has both active and passive inputs.  It too has a resistor ladder volume control.

Surprisingly the comparison between the two isn't even close; the Perla Audio preamp just kills the T+A preamp section. 

Better tone, bigger soundstage - especially soundstage HEIGHT.  More air and space around the instruments, more holographic.

How a passive preamp is doing this is a mystery to me, but it is just much better than my DAC and I've discovered it's the heart of my system.  I won't be going to a DAC volume control any time soon.

T+A DAC 8 DSD
 We have again further improved the unit’s outstanding pre-amplifier, and incorporated a volume control of fully analogue construction based on High-End Melf resistors. The “State of the Art” output stage is of fully symmetrical design and discrete construction. Its impedance is very low, and it is equipped with symmetrical(XLR) and asymmetrical (RCA) outputs. These features make the DAC 8 DSD more than just a High-End converter: it is also a High-End pre-amplifier of supreme quality.

T+A DAC 8 DSD Different ladder resistors they are Melf not Visay. But it is a full discrete preamp output stage with more than enough output.

It doesn't say anything about the Perla Audio Maestro being anything but a passive preamp. 
It uses power, but that's just for remote receiver and volume control movement duties, it's still a passive looking at the website.

Georgie, fyi, emcdade is stating, in the last paragraph of his post, that his Perla pre " is a passive " unit. Man, you are always defensive and ready to fight. Relax there fella.

I call it correcting wrongs, "looking for a fight" doubt that very much.
"Relax there fella" Really!!!

My preamp is the Perla Audio Maestro which has both active and passive inputs.

There are no active inputs. What emcdade was stating is simply wrong, and I corrected it.
  
And please!! don't call me Georgie, that's only reserved for my blonde Russian mini skirted music teacher, when we play "teacher and student" and I've been a bad boy!
