What is the #1 equipment want currently on your HiFi horizon???

Maybe upgrade my Aerial Acoustics 7B to the 7C. The 7B is a great speaker with the right amp and I’m not sure the difference would be worth the cost. 
Next would be upgrade Pass X250 to a .8 series. Had a .5 series to compare in my home and yes I could hear a difference for the better with the .5 but it was ever so slight so I passed thinking to hold off for a .8

Likely next upgrade will be a streamer. No way of knowing but thinking my current streamer is the weak link, assuming I really have one.

Tonearm for now. Maybe up the Origin Live line. But then I listen to mine and I ask, why? Maybe tubes. I need some backups. Then there's the Chinese  ultrasonic record cleaner. You'd think we've had enough cheap stuff from China. before that it was a streamer. That was a disaster. Sounds good when you can get it to work. It was supposed to be more convenient. Sure it is. More modern BS. Whatever the case I need to buy something. 

Genelec W371a.

acoustic treatments and padding is the nearest item.

In terms of actually upgrading my main system - an Exposure 5010 preamp.

In terms of "just for fun," either Thiel 3.6s or KEF 105/3s.
