Connecting a DAC directly to an amp?


Do I need to insert a stereo preamp between a volume controlled dac (chord tt2) and an amp? Impact to sq?

George, I thought Chord used FPGAs.

His is the NOS R2R Metrum Adagio
And if the vc is "not in the signal path", then it’s either in the digital domain, or horror if it’s changing the output stages feed back, to control the volume up or down, as then the vc sonics will have different characteristic as to where it’s set with the amount of feedback applied.

.
The minus 10dB is optioned by a switch on the back and I do not have that engaged.
Maybe you should and try direct again.



Or we go back to my first explanation of
10k is a very low input impedance, there’s no need for it these days, as things have problems diving it.
47k or higher is the industry standard, some tube amps like Rogue M120 mono were up to 1000k!!! (1mohm)
But if your source output stage is weak and maybe cap coupled (which could be too small with 10k) it’s the problem, not because your going direct.


Cheers George
This is getting confusing (and my previous post didn’t help); the OP, “emerging soul” is using a Chord tt2. “mitch2” is using an Adagio.
This is getting sooo damn complex for my tiny mind.  Very very and maybe toooo techie

To put it simply, your Chord Dac using the remote variable volume output from it’s line outputs, gives over 5volts!!!! at full volume. This is more than enough for any amps on the market.

Use it direct into your amp and forget about buying a preamp, save the money and get sound that more transparent/dynamic/uncoloured in the process.

Looking at a modwright ls300 tube preamp.  Hard to plug dac directly into amp when I have an avr.  Only use for streaming.

tube preamp allows ease of functionality between avr and preamp.
