Have you considered trying some acoustic treatment such as wall panel absorbers or diffusers ?
Do you suffer from flutter echo in your room , an easy test is to clap you hands loudly once and listen for a fluttery echo a split second later .
If you are suffering from this effect then it might be the cause of the inconsistent mid range performance of you system but unfortunately no change of equipment or speakers will cure it , but strategically placed acoustic wall panels can really help.
Gik Acoustics are very good at sorting this sort of problem if you have one
Not cheap though are they!
There must be a cheaper DIY to make bass traps, and hanging drapes on walls to reduce echo.

I couldn't realistically get those panels past the OH without WWIII breaking out.
Anyway, I'm currently playing 'Splendor Solis' by The Tea Party and it sounds stunning. My system really seems to go from the sublime to the unfathomable.

It might be worth running a 20hz to 20khz frequency sweep on your system to see if you have any nasty midrange peaks that are setting off narrow frequency reverberations in your room , the sweeps are found on some test discs or can be downloaded .
If you have a nasty peak it will only show up on recordings that have sustained energy at that frequency hence why some recording are fine and some less so .
Definitely worth a try even if it is only to answer the question as to why the inconsistency in sound quality

How does one measure hz and khz? Is there such a thing as a khz meter?
There maybe another valid reason for this slight sonic discrepancy: Perhaps I'm expecting too much from a £600 speaker.
Currently playing Experience Hendrix 'The best of Jimi Hendrix' and the 3rd track "The wind cries Mary" sounds awesome: The snare drum has a slight echo; the bass is strong and tight but no heavy bloom, while Hendrix's voice is packed with presence and realism.
It's almost like my system has too much transparency to the presentation, if that's possible.
Anyway, a hi-fi free afternoon.
I've got that CD so I played "The wind cries Mary" and had a careful listen. It is "awesome"! I'd never thought about it before but it is a brilliant recording and I'm increasingly of the opinion that what you are hearing could just simply be the difference between good and bad recordings.
I wonder what else you have that you think sounds outstanding or not so good.
I knocked up a panel as an experiment. Works a treat and much less expensive than buying ready made panels. You also have a much greater choice in covering materials to suit decor.

Absolutely no meters of any type required
Simply run a frequency sweep track from a test disc , I use one that came as a free gift with HiFi news, or you can download one and burn it to a Cdr .
Start the sweep and listen ,if the pitch rises evenly an the volume stays roughly the same then the room is reasonably flat but if the volume seems to rise or fall sharply for short periods at certain points in the sweep then the room is adding or subtracting certain frequencies .
The sweep will find the resonant frequency of certain objects in the room and they will vibrate in sympathy causing them to rattle and vibrate so this is a good time to stick a small blob of blue tac under the offending objects and eliminate some of the strange sounds that these things can cause .
It can be a real eye opener or should that be ear ?

And also a can of worms opener, when trying to solve the peaks that were hitherto undiscovered.
Depends which way the worms wiggle.
On a sensible note though, a frequency sweep test tone is a good way to see if you have in your system (room included) any particular frequency 'humps', 'troughs' seem less easy to detect. I used one such test tone when I was trying to integrate a sub and found that I was sitting in a null point for the bass. I simply couldn't hear any noticeable bass, until that is, I stood up. It was an eye opener to how much speaker placement and listening position can affect the sound and also where the frequency peaks are in the system.
Understand - I think it's pointless, due to the crumby design of the bungalow, if there is any deficiencies I can't make any significant placement changes. It is pretty much cast in stone, unless we move...
DIY acoustic panels are a worthwile exercise, even if to discount the need for them. There are a few threads on the forum about such topics.
It does seem though, that the solution you are looking for is speaker related. Acoustic panels do seem to make the sound more 'focused' if that makes sense, but I wouldn't know if they made the sound more 'class A'. I don't know that amps make that much difference to the sound presentation anyway (assuming they are capable of providing the required current/volts under demand), particularly when compared to speakers.
Whenever I have changed amps, I've usually been underwhelmed by any differences, if any were detected. Speakers on the other hand seem to have much more variation in presentation, as I'm sure you are aware.
Fully concur that additional help with 'panels' can make a difference, but short of padding the walls I'm not sure whether any noticeable improvements could be made.
As I pointed out earlier, expectations may just be a tad high, allied to bad recordings.
After playing a number of cds this morning my system does seem to embrace the 'rockier' type of music. Any of the robust styles like Hendrix, Costello, Tea party, Roxy music it sounds pretty natural, whereas it struggles, generally, with the well crafted or considered tracks like Joss Stone etc etc.
When I played Weller's 'Wild Wood' album I found the drumming to sound a little boxy, although the title track was fine.
This might help PP:
Maybe what you are after is a bit more second order harmonic distortion?
