Why do I need a preamp?


I’m running a Vega DAC direct into a Pass amp with balanced interconnects. DAC level is set to maximum. and I'm controlling volume through JRiver/JRemote. There are no other sources. I’m happy with this sound quality.

Some people say this is wrong and I need a preamp. I don’t understand how adding another device into the signal chain can improve SQ, even if the the preamp is completely neutral and doesn’t inject its own sound.

If anything, I had thought about a passive pre like a Tortuga which is generally accepted as being pretty much dead neutral, but not sure why I even need this.

Thoughts?

Maybe it is that you don't need a preamp. If you don't plan to have any other sources, you might be just fine.

One concern might be that the DAC, although balanced, might not support the balanced standard. That is a common problem in high end audio. The point of the standard is to eliminate cable interactions with the system, so you will know that there is a problem if you can hear differences between interconnect cables.

This **could** be solved to some advantage by a preamp that does support the standard, but IME high end audio preamps that support the standard are few and far between!

Another concern is how the volume control functions- as in: does it cause audible loss of resolution at low volumes? This is an area where an analog control can work a lot better, but FWIW, IME the JRiver system works pretty good.
