Tube Amp + A/v receiver question

[pevsfreedom]

Hello,

I wanted to buy this:

I already have this:

I have a Yaqin tube pre-amp for my turntable. Can I run the cables from the pre-amp into the tube amp, and then into the A/V receiver [for simplicity, so I can use the speakers for other stuff too].

Would this be 'bad', or even work? Would it be pointless? What benefits (if any) would the tube amp have over using the SS a/v receiver as an amp?

Thanks in advance!
