Preamps built Into DACs

.
After reading all of the above, the high end tube preamp is the way to go for me. In five years as digital technology continues to evolve, I'll revisit the feasibility of using the preamp section of a DAC.
.

"The besst overall solution is to use a good volume system to reduce the volume to listening levels and then adjust finely for each track using -0 to -9dB of digital volume. Works like a champ."

I agree this is probably the best strategy in most cases today.

I try to keep the volume control on my Squeezebox Touch controls at max normally, then set my preamp volume to desired volume level for most tracks. Then I use the TOuch VC if needed to lower the volume a touch if needed from there, especially for louder recorded tracks. A bonus with a device like SB Touch is that remotes, computers, tablets, handhelds or any wireless device with a web browser can be used to tweak the volume down on the Touch from anywhere in the house as needed.

Mapman - Look, I have used a few digital volume controls, including the one in the DEQX, iTunes and Amarra. By far, Amarra is the best sounding volume software so far, and it starts to affect the SQ at more than -9dB. I can hear this because I have on of the most resolving systems on the planet. I clearly hear lyrics in tracks that noone else can make-out.

In most peoples systems they will probably not hear this effect until maybe -20 dB or more. This is due to the fact that there is so much other noise, distortion and compression in the typical system that these effects are masked. This masking can be caused by jitter from the source, active preamps and even poor amplifiers.

"the reviewer preferred Bel Canto, which has Digital VC"

I read this review. I think the digital volume they are talking about is a digitally controlled analog volume chip. I dont believe it is DSP. They also used a certain low-jitter USB to SPDIF converter to drive the DAC BTW.

Steve,

I have no doubt your system is ultra resolving.

Can you tell me what it is, out of curiosity?

Thanks.
