Post by PixiesThe variables that enter the analysis are the brand of the speakers,
the size of the speakers, the brand of the amplifier, the type of
amplifier, the type of music, and the location of the speakers in the
room---and probably more. I tested KEF iQ5, iQ7, B&W 603 S3, JBL E80...
KEF speakers had a deep lack of bass, since they seem to be more
focused to jazz... On the other hand, B&W are more focused towards
classical... The type of music I use to listen to (rock and pop) could
be better fitted by JBL, according to the seller... however, he also
told me that, if that was the type of music I use to listen to, perhaps
other brands such as Monitor Audio would be more appropriate.
I don't know who is telling you all this--a salesman?--but I wouldn't
put too much stock in it. I know someone who is very happy listening to
rock and pop on B&W 603s, for example. To each his own. Also, a good
speaker isn't "focused to" a particular genre. A good speaker
reproduces sound accurately, whatever the sound is. (Granted, no
speaker is perfect, and some sound better--to some ears--with certain
types of music. But the best speakers won't specialize.)
If you like a particular type of music, you should bring some samples
of that music with you when you audition speakers. Then YOU can decide
whether each speaker sounds good playing YOUR preferred music. That's
all that matters.
You're right that there are many variables involved, but some variables
are far more important than others. Speakers matter a lot, and
speaker-room interaction matters a lot. Testing the latter requires you
to get the speakers into your room, which is tricky unless you can
wangle loaners or return privileges. (Good luck with that.)
Amps and speaker-amp interaction matter much less. Most speakers on the
market don't present killer loads (because speaker manufacturers have a
strong incentive to produce speakers that can be driven by lots of
different amps), so you don't have to sweat this one too much,
especially if you're sticking to solid state. I suggest picking out
your speakers first, and then going with an amp from the same store.
The key thing to remember is that there's lots of good gear out there
these days, so you don't need to obsess about finding just the right
thing. (You can if you want to, and some people do, but it's not
required.) Listen to the speakers you have available to you, playing
the music you like, and pick what sounds best. It's not so hard.
