Monitor Audio

Any advice on an upgrade without breaking the bank? 

I have Silver 5i in my bedroom system, they have a very good sound. They hold their own in my opinion. Very clear and detailed with my modest gear.

I bought them used for a few hundred, fwiw. 

Sennheiser 1. Do you have a speaker recommendation for me. May I ask what you are using? 

I'd highly recommend the Silverline Minuets.  Heard the original version powered by relatively cheap electronics at a NY audio show and they blew me (and many others) away.  Best of luck.

If you’re willing to consider used, I’d suggest Totem Rainmakers in that relative price range. How about Definitive Technology Studio Monitor 65? I really liked their sound as compared to many other comparably priced (and sized) monitors.
