Thinking about selling my Vincent 737

Hello! I'm still sort of a noob when it comes to the audiophile stuff, so be gentle!

So, ive had my Vincent sv737 for a couple years now, and make no mistake, i love the thing-- albeit without a lot of a/b reference points. But i think i might be ready to try something new. I love the soundstage and 3d depth of tube sound, but also like tight bass and detail. My question is: if i sold this guy, what would be my best bet? I have a gustard x26pro dac, a zen ifi streamer, and some klipsch rf8000 f speakers.

Was thinking a tube pre amp and a separate solid state power amp or mono blocks?

*Having the dac and streamer is a part of why im considering the sell. Im not using the built-in ones in the 737. Maybe i can get more bang for my buck?

Thanks!
