Which receivers would you recommend within the $500-$700nrange?
The feature that your Sony receiver may be weak or deficient about would be its automated room tuning facility. The best around is called Audyssey Multieq XT32, and I don't think your Sony has it. Last I looked Sony has their own which is mystery meat to me.
You don't say it explicitly but it appears that you don't have a subwoofer. Among other things a good subwoofer offloads your AVR.
The impedance curve of your Mozarts is as follows:
This should not be something that a good AVR would stumble on but you don't say exactly which AVR you have, so it is hard to say more in your situation.
However these speakers are low efficiency according to this reliable review source.
Stereophile finds this response curve for your speakers:
which does not indicate robust bass performance.
The response curve also shows a big dip in the midrange which the reviewer attributed to a serious error in construction that can be alleviated. I suggest contacting the manufacturer for advice and correction. At this price (> $2k per pair) this is a serious lapse of QC is IMO inexcusable. Nobody with good ears is listening to the finished products, it is as simple as that! This kind of failing would be inexcusable in $100 speakers! My goodness!!!
This limited bass dynamic range problem is confirmed by my highly optimistic model of the bass dynamic range of your L & R speakers:
Freq,Hz Max SPL, DB
These speakers run out of gas as high end speakers at 80 Hz, and as mid-fi speakers around 45 Hz.
The acquisition of a good subwoofer is indicated. I usually recommend that your subwoofer budget should be based on what you paid for your L & R speakers.
Then there is the matter of room acoustics treatment, etc.
In short there are many reasons why you are not getting what you expect out of your existing system. I would start with getting them corrected and then a subwoofer, but everything mentioned above is important.
