Speakers for onkyo A-9555 integrated, advice pls?

I have this amp and I would like to hear from owners what it has been their experience with this amp and speaker synergy, cables etc.
I am so looking forward for the right match, it will be for a second system and my budget used or new is less than 1k.
Thank you always.
My choice for under 1k speakers are the JBL L890s. You can get these for $800 all day long. The Onkyo is on the "warm" side, the highs are a bit rolled off, and the JBLs can be considered a bit bright. So, imo, it would be a good match.
There is a nice set of Thiels on A-gon right now for 1200 that would sing with that amplification.
