That's all stellar equipment. But if I was looking for a different setup, I would be looking at going in the opposite direction in terms of builds. If not, it's just a lateral move. Meaning, I'd look at direct drive decks (like Technics SL-1500C) with a moving coil cartridge (like AT33Sa). Then check out options for integrated tube amps (so many great ones out there). Klipsch would be fun to check out. I would just try something that has bigger bass drivers than the 5" on BP8s...like Wharfedale Lintons or KLH Model 5. 
 
Fun, fun! I'm jealous. Enjoy the ride.

I currently use the Vincent PHO-701 in one of my systems, and it's excellent. Can't say enough about it. The tube output warms up things beautifully. Excellent detail. Separate power supply to cut distortion. Plus, I've moved to moving coil cartridges,  and all the load/impedance option switches really let you dial in the sound. I've removed the 701 on a few occasions just to use the internal phono stages in amps, but I always end up putting it back.

Wifi doesn't compress music (different than Bluetooth tech).  So whatever analog signal you feed that Sonos speaker, it will faithfully reproduce it digitally up to CD quality. Keep the signal as clean and strong as you can, your ears will thank you.

Yeah, in that budget range you're probably making the right decision. I'd keep in mind the Klipsch powered speakers as well. I own a pair of the R-41PM and sound brilliant. Rega is an excellent preamp.

My two cents...first two pieces are great, I'm just not sure about the speakers. Great company, but curious why you're going with powered speakers. Lack of space? Budget? I've gone that route before because of space issues, but in the end I gave it up. The sound wasn't as full as I wanted. It was good but not great. To build speakers like that, they have to stuff a ton of components inside that tiny cabinet. In my opinion, you lose some fidelity in the process. The other thing is, if you want to upgrade and find a separate amplifier you like down the road, you will have to get rid of those speakers. But I don't know what your set up is...if this is like a second system for an office in a small room, your choices will work perfectly. If this is your main system in a living room, it will sound good. I just think over time you'll find it lacks some depth and you lose future upgrade options.
