@helomech I recently purchased a nice conrad-johnson tube amp and Vandersteen speakers. I didn't have an extra dac or streamer, so I ordered a Wiim Ultra for $279 instead of robbing from my main system to test the amp. I'm pretty amazed at the sound quality. I have it connected directly to the amp and I'm using the volume control on the Wiim. The preamps that I have in storage are old and I doubt they'd sound good.
I haven't compared the Wiim directly with anything, but on its own, it sounds really good. I told my wife that an inexpensive piece of gear like the Wiim probably doesn't often get paired with a high quality amp like my conrad-johnson.
