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.

Second the Schiit SYS...currently use in injunction with Gustard A18 DAC and output SYS to amp...yes, one loses convenience of remote, but alternative was to offset DAC by ca. -30dB, with possible bit loss on lower vol. playback.  
What I have gathered is it is better to have a separate DAC and preamp. In that case, a volume control or gain stage woodwork the same. So would a buffer preamp such as the pass DIY for $150. I just don't see spending over $1,000 on a preamp , just to have volume control. Considering I only need one input, any simple desktop volume control solution works. That also opens up almost Endless Options.
+2 RME. Great on its own but upgrading the power supply steps it up considerably.
+3 RME DAC. It goes directly into a Pass Labs power amp with balanced interconnects. Sounds great. Upgrading the power supply is intriguing but probably way above my pay grade. The RME has a remote so no need to leave your chair that's in the sweet spot.
I get it. The RME DAC is amazing. I've been helping my daughter with a serious legal issue, and money is very tight. This would be at the extreme reaches of my current budget. If I bought this, I would have zero money left for a preamplifier if needed. I was looking more along the lines of the smsl products under 500. And adding that to something like a pass DIY buffer amp for 150, or a simple stepped attenuator volume control. About half the budget of the RME. I never planned on spending a thousand for a DAC unless it doubled as a preamp, without hurting the sound..
