Peter, reading your & others' posts and noting yr budget, I don't think you can get what you're looking for, the way you're looking for it:
i.e.,
* one stereo amp, driving more or less full-range speakers (you listen to music that requires mid-bass, voice and hi-freq (cymbals, etc) -- including brass, etc).
* low amplitude reproduction that is acceptable enough to envelop you in the music (or trick you to focus on the music, as it were).
* reasonably sized spkrs, compatible with a family room.
So, I believe you would be well advised to consider somewhat less conventional solutions -- such being, active speakers, for example.
In this respect, many can fit the bill, the most obvious coming to mind being Linkwitz Orions or ATC.
I think $: 7k can buy you a pair of Orions ready made (i.e. you can also purchase a kit) including the amplification required to drive them and the electronic xover.
ASAIK, the Orions' reproduction will outperform the (very good) commercial choices listed at any volume level below 110dB spl; they are not that big; they have reasonable aesthetics (go to linkwitzlab dot com); they are very versatile -- i.e. easily set up in a room.
Many would give (their) right arm (for) a pair of 4345 JBL Monitors.
Maybe; I would agree these are interesting spkrs -- but they are huge and probably aren't practicable.
Cheers
