Damn there is a lot here to cover. No way to do it in a post - would probably need a book.Ok - there are 4 key elements to any system:
The System itself.
The Source (CD, vinyl W.H.Y.)
The room.those 3 are roughly equal in importance, and finally:
SYNERGY!
If the components above (and the components of each) work well together that, IMHO, is the most important thing. In a system that has roughly equivalent equipment where they have been carefully matched changing one item in the system may have:
1. No effect.
2. A degredation of overall quality.
3. An improvement of overall quality.A change, such as may happen might be dramatic or rather subtle.
The most tempting answer to the original question is therefore another question:
"What do you not like about the way your current system plays?"
The answer to that question may yield more insight into the possible changes that can be wrought. If you want more bass you can add a sub, change speakers and even amplifier.
It might be you would benefit from room treatments, from a new source or even an EQ.
Impossible to tell from this distance. Not all that easy to tell without hearing the way you, the owner, does.
Obviously any choice should include the benefit of a home audition.
As for the all components sound the same (e.g. amps) the answer is yes and no. Given a constant load and staying within the operating load of the amp they do all sound remarkably similar within a given topology. The thing is that speakers are rarely constant load and audiophiles rarely listen to music so compressed that there are not wild swings in what an amp is being asked to do.
With wild swings in frequency and volume amps become easy to differentiate - especially with difficult speakers.
For example - take the Quad 989. In theory you can drive this speaker with an amp of 100 watts or maybe even less. Trouble is that the impedance of this speaker drops at various frequencies to 2 ohms or less. This will kill even very good amps. I watched an Accuphase E211 shut down with these speakers (90 wpc) at VERY moderate volume levels.
At the other end of the spectrum take a Klipsch Heresy 2 speaker. 96 dB sensitivity - apparently a nice and easy speaker. Mate it to a Yamaha 595 surround sound amp and you get no bass (90 wpc apparently). Mate it to a 35 wpc tube amp and you get masses. Why? Well the Heresy is not the easy load it appears either - but its impedance does the opposite of the Quad above. At points the impedance of the Heresy hits almost 40 ohms. The Yammy cant cope with that kind of impedance and runs out of juice resulting in being unable to drive the woofer. The tube amp does seem to be affected and drvies it fine.
The point here - is that although you can set up a test environment to show amps play the same - and in fact it is rare to find an amp that will not measure almost flat in the range 20 Hz to 20 MHz into a CONSTANT LOAD - in the real world this rarely happens.
