Preamps built Into DACs

There do seem to be certain components that manufactrurers love to combine and DAC Preamps is one of them. I am no EE and don't understand the allure but you do see a lot of them. Amp builders I have spoken to seem to get a charge (no pun intended) out of building preamps. The reason remains somewhat unclear but to the ones I spoke with it was the challenge of the circuit. I somehow doubt that is why, I think it more an economical one and we need a frank discussion of that.

Audio-Gd has several, this is his starting price point ($549 no remote, $599 with) they go up to about $1900

Preamps, great active preamps, are a must for me. Without it music is
simply not as musical to me. So preamp builders please build on! To my
ears a proper stereo system needs a great active tubed preamp.

To me, I would be wasting money on my system not having my active tube
preamp. So yes, stop putting a volume knob on all those DAC's so when I
buy one I'm not wasting money on that volume knob.

To each his/her own and this is just my experience and preference. Listen
on!

Many have ditched very expensive preamps for a well implemented volume control in the DAC(including me). Considering the amount of loss incurred in an analog cable and running signal through additional circuits I am not surprised.

To me there are no sacred cows in where to put the volume control (which is what we are really talking about here). I used tube pre, solid state pre and now the volume control in the DAC. Then there is the whole debate about analog VC and digital VC in the DAC.

I think the ideal VC implementation would be a DAC with a switch for 0db, -10db, -20db, -30db, -40db attenuation in the analog domain to match DAC output level with speaker sensitivity and desired volume level for the listening session, and then a digital remote control to attenuate up to an additional -20db. Wonder why no one has build this.

If you have just digital sources there is probably no good technical reason to have a pre-amp. I'm sure there are very good dac with volume controls out there. Maybe to introduce tubes in the pre-amp if a tube sound only fan.
