Please do offer your Loudspeaker options and how much more is truly needed to get a truly resolving speaker without taking out a mortgage.
The trouble is that the loudspeaker needs to be married to the proper chain to deliver as intended=source>cable>preamp>amp>speaker wire>speaker> ROOM acoustics
Any misstep along the way and dollars get wasted.
I would recommend an active "system" like the Kef LS 60, the Dynaudio Focus 50, Klipsch The Nines, etc.
In my experience you would need to spend $$$$ more money to get better SQ with separates and might still miss.
The Sevens by Klipsch are active speakers and cost $1299 so I would say that is likely the entry point for a truly resolving SYSTEM.
