DAC as a preamp?

I need a new DAC. I use my computer for volume control, but do not trust it. I want separate volume control. The 90s me would have immediately thought preamp. But since I need a new DAC, my question stands ... DAC as a preamp?
I've posted more info about my system below.
I need some advice on the best way to go about getting volume control for these powerful asp1000 amplifiers. I've read about the high input impedance. I use a computer for my source playing Flac, wav or hi-res audio files. I'm using a very simple dongle Style USB DAC that sounds okay. I have choices, but do not know what my best bet is. For simplicity, it would seem I should just buy a better desktop DAC, such as and SMSL M500 and use the volume control knob on front. Or ANY other DAC with a volume control for that matter. I know I can use my volume control the USB. Provides through the keyboard on my computer. But with amplifiers this powerful, I figure I should have a volume control to prevent issues such as full volume noise blasts, which have happened before when the computer glitches. My second option would be to purchase a regular preamp. This would be the most expensive option, as I would want something at least as good as the Schitt Freya +, and that is $900! I would still need a decent DAC upgrade. This gets expensive with my health issues at hand. The last way I could go, is something like an all tube gain stage. I would still need a DAC, but a simple gain stage kit should only be a few hundred at most. The other two options I can think of, would be the pass B1 buffer clone kit preamp for 150 dollars, but I don't know if it would play nice with a high input impedance of the icepower amp. The most simple and cheapest route, would be be using the Sure digital volume control option. But I do not know how high fidelity that would be. I could really use some help. I've been out of this hobby for about 10 years now. I feel a bit lost and appreciate everyone who has helped so far.

@unsound. I'm only doubtful because the DAC outputs 4 volts. Which is what the amps need to achieve full volume. BUT I would probably be using the first half of the DACs volume, instead of the last 30% of 100%. From 70 to 100% being quiet to thunderous with 1000 watts.
I'm not opposed to the Schiit at $49. I enjoy learning, and was wondering what the actual best option for my situation really is. There are walwart powered stepped attenuators, alps set ups, buffer like the Pass clone, whatever the Schiit is, etc. I figured there was a rank from best to worst options. It was just curiosity to be honest. I love this audio stuff, and this is something I truly don't know.

It's been pointed out this is a very technical forum. I am new to this part, having never owned a setup like this before. I believe I understand the most basic parts. My amps need 4v to achieve full volume. The DAC outputs 4v . Used as a straight DAC out at 4v, it would immediately produce full volume, without a way to attenuate the 4v. But you want to use between 70 percent to 100 percent on your DAC volume control to prevent sound quality loss from lowering the bit rate. Also, keeping your signal high allows for lower noise floor. Is this correct?

ALL I want is remote control volume control that won't degrade my sound quality. That is it.

Computer to DAC to attenuator of some kind to the amps, right?

And only curiosity makes me ask ... with Nelson Pass a legend, why wouldn't the kit at $150 be among the best options possible? Or is this going to harm my sound? Wanting to learn if you're willing to educate me.

@flaxxer, what is the sensitivity of your speakers?

One of my systems is an RME-ADI2 amp to two Schitt Vidars.  Linn LP12 for analog, Audirvana for digital.   I use a MacBook as front end.

I recently deleted my preamp.   

Pros:
- You can really invest in interconnects, since there is only one set of analog interconnects in the chain.
-  Clean, clear sound.
- More dynamics
- Save money.... in theory.

Cons:

- Volume control affects the sound more than with a preamp.   If you are at -30db on the DAC... there's going to be some issues.
- A bit of a dryer, more analytical sound than we a pre.

I run my LP12 through a D-A converter at 24/96.   Maybe it loses some immediacy vs pure analog, but I enjoy the tone control of the RME for it, and it's a fuller sound than when going through a pure analog path.

Overall, there is no right answer.   You need to experiment.   If you can't afford great interconnects, then definitely try to avoid a preamp... running through an extra set of mediocre cables will hurt your sound.  

I've played with attenuators - they did more harm than good for sure. 

In an ideal world - you would pair your speakers, amp and room so the DAC is at a reasonable level at the volume you tend to listen at.
