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.

@nsm1979... thank you for your reply. This is kind of what I've been thinking. While I have seen the Small Tube preamps under $100 on Amazon, I figured they were all real trash. You make me figure I should go ahead and try one though. What I would really love, is to be able to build and all tube gain buffer 4 less than $300.
I may have messed up. The input impedance of the asp1000 amps is just under 8K
I really could be wrong, but I truly believe this is what I need most. But it is very expensive for what it is. There is a view with the top off if you scroll down the page. Does anyone know if I could pay someone from The Forum to help me design something like this gain stage with tubes?http://https//www.decware.com/newsite/zstage.html
Decware is really nice. If you get on the list right now. If your lucky they will be pulling parts in 4-6 months. No that doesn’t mean it will be finished.

They are really SLOW, now. The first time I ordered from them 10 plus years ago. 3-4 weeks. Now 6 months.. If I wasn’t into this for 4 months and didn’t need a direct head out tape preamp. I’d be on someone else’s list. That guy needs to hire some help.. You’d think it was a Dodd special or something..

He is loosing a ton of sales, behind it.. I know a buddy just dropped 25k on new MB. Decware would have gotten the business. He got his MB in 3 weeks. I haven’t has a chance to even see them. I think it was Triangle Art. He has 2 or three of their TT, I'm looking at one of their TT myself.  That same guy has 3 Dodd units.. One of my top 5 picks of all time.

All of Schiit Audio's headphone amps can be used as a preamp. I own a Modi Multibit (DAC)/Vali(tube headphone amp/preamp) combo that I am using in my bedroom. It sounds fantastic. 

In my main system I am using a Schiit Jotunheim with a phono card. It gives me one phono input, one RCA input and one XLR input. It has XLR and RCA outputs. You could substitute a DAC card. I went external with a Gungnir Multibit. If you want a DAC that is the same size that would stack with the Jotunheim you would be looking at the Modius or Bifrost DACs

My living room system...the system I have had the longest...has a Saga and Modi3. I really like all of them. I also admit to being a Schiit fanboy that prefers tube amps. 

On the low end you could have a Modi 3/Magni combo for $200, a Modi 3/ Vali for $250 or a Magnius/Modius for $400. The Jotunheim is the only headphone amp/preamp that has three inputs. The $100 DAC card is a USB only Modi. The $200 Multibit DAC card is a USB only Modi Multibit.
