Low gain dac!

@gryphongryph somehow the address on my last post did not take.

@luisma31,
I sincerely appreciate your very kind comments. I’m in complete agreement with you that the importance and influence of the DAC analogue output stage is overlooked. Same applies to a DAC ’s I/V conversion and power supply. Yes the chips play a definite role but too often overemphasized.

@gryphongrtph, I believe that the Sonnet Audio DAC you linked and the Audio Mirror Tubadour (Recommended by mesch) are very viable options. Their 2 volt output would be much preferable to the 4.3 v of your current DAC.

Obviously you’d need to hear them to know for sure but in terms of system gain management, a move in the right direction.
The Tubadour consistently receives high praise. The Sonnet is unfamiliar to me. It sure looks interesting on paper however.

Isn't 4.3V out on RCA from the dac against the normal specs/standards?

I thought they were supposed to be 2V on single ended outputs and 4V on balanced. I think some DACs have higher output when they also contain a volume control, the idea is that they can work without a pre-amp in the system. If your amp has a volume control you can just lower that and try how it sounds.

Yes it is true that the gain on my Primare Dac is higher than the industry standard of 2v.

The dac does not have a volume knob or any way to adjust the output.

 I don’t know why Primare decided to do this, maybe most of their customers normally use the balanced out on systems with more than one Primare component?

My thinking is just to get the gain a bit down with a source that has the standard 2v output.

Yes the Redbook standard was 2v back in the 80's but since 2000 it's crept up now and the norm is 3v or more, which is good, as the higher the source voltage, the less end noise/hum/distortion there is because of less amplification needed down the line.

Nelson Pass,
"We’ve got lots of gain in our electronics. More gain than some of us need or want. At least 10 db more.
Think of it this way: If you are running your volume control down around 9 o’clock, you are actually throwing away signal level so that a subsequent gain stage can make it back up.
Routinely DIYers opt to make themselves a “passive preamp” - just an input selector and a volume control.
What could be better? Hardly any noise or distortion added by these simple passive parts. No feedback, no worrying about what type of capacitors – just musical perfection.
And yet there are guys out there who don’t care for the result. “It sucks the life out of the music”, is a commonly heard refrain (really - I’m being serious here!). Maybe they are reacting psychologically to the need to turn the volume control up compared to an active preamp."
