@ranmart I would order it if there is a return option. Again, to me the speaker is the weak link in this Rega package.
The easiest way to upgrade is to buy gear that others want - it will be easy to sell and not lose money. I think the most important part of the system is the amp. I learned it slowly and at my own expense but it’s the soul and heart of your system. The second most important thing for me was aesthetics/culture.
Your room is a nice size for smaller speakers to make it work.
I don’t like brand recommendations because it’s so subjective, I think there are 20+ brands in each category that work well. The key is how they work together, the magic word: synergy.
I swear by Rega and Fluance for turntable. I also had Project and mmf, Project is great too.
I would research what phono amps are best in integrated amps, because there is a wide range, I only know the brands I had and kept.
I spent a lot of time to test speakers in the 1000-1500 range, new so that I could try them out, but they cost 5-700 used. I tried 9 different pairs in 5 months and the more I tested, the unhappier I became.
I only fell in love with Monitor Audio, Dynaudio and Totem speakers but it’s all subjective. In your price range there are a lot of cool speaker brands, the resale value would be decent on Sonus, KEF, Klipsch, B&W, etc. If you have the time, look at usaudiomart, where I bought and sold most of my gear. I read great things about the Zu, and I am very interested in Buchardt and Harbeth/Spendor speakers, higher end of the budget.
There are audiophiles with gear worth of 10s of 1000s on this forum, the only reason I comment now is that I had the same budget as you. I eventually ended up with Rega P3 - slightly used, MF A3.2 Amp, used and Dynaudio Evoke, new speakers. I can’t say I am happier than I was 3 years ago when I started switching everything out, but that’s the bug thing, it’s about the journey. My marriage is definitely under a lot of stress because of this. :)
the good thing about your budget is that audiophiles with the bug will want to upgrade from their current system and will sell their grear for under a $1000 that they bought for way more. It just takes time.
