It does come down to individual choice, and if you love your Bose, then stay with them and be happy. You asked for better than Bose, partially out of curiosity and because you have a choice to make, whether to leave the speakers behind and get something different or replace them with more Bose. Like you mentioned, there is also the Rolex factor, in that the Bose marketing has made them the Cadillac of speakers.
Some things to consider - most if not all of the speakers suggested, in tandem with the subs included will cover the whole human listening range of ~20Hz to 20KHz. If there are dropouts or fluctuations, then you are either missing sounds, dialog, etc. from movies, music, games that you're playing.
The Bose system has gaps at:
20 Hz to 46Hz , 200 to 280Hz, 13.5kHz and above.
That means that you are unable to hear those sounds, since the speakers can't reproduce them. You may hear the harmonics to them, which are much weaker copies of them at other frequencies, but they are not the main signal.
The human listening range covers these frequencies that we're all interested in for music and voice (song and dialogue) - I've highlighted the sounds that the Bose speakers will not cover
For Instrumental Music:
Instrument Frequency range HzPiano (concert) 27.50 - 4,186.00 Low end, covered by a good sub, other range just missing.Bass Tuba 43.65 - 349.23 upper half,Double Bass 41.20 - 246.94 top endCello 65.41 - 987.77 in the lower areaViola 130.81 -1,174.00 in the lower areaViolin 196.00 - 3,136.00 low tonesClarinet 164.81 - 1,567.00 low area
Flute 261.63 - 3,349.30French horn 110.00 - 880.00 low endTrombone 82.41 - 493.88 middle half
Trumpet 164.81 - 987.77 mid to low
Guitar 82.41 - 880.00 lower area of notes
For human voices:
Type of voice Frequency range Hz
Bass 87.31 - 349.23 heavily affected
Baritone 98.00 - 392.00 as is this
Tenor 130 - 493.88 mid to lower half
Contralto 130.81 - 698.46 lower area
Soprano 246.94 - 1,174.70 mostly unaffected
Any sounds over 13KHz you won't hear either. Human hearing goes up to 20KHz, most people vary, but for example I was tested and can hear to 17.5KHz (getting older).Here's some more information on frequency vs. what you want to hear
Another problem with Bose speakers that has been identified is that the range of their activity is measured (independently) at +/- 10.5 db for their response across these frequencies. That means that the ability to reproduce the above sounds for Bose speakers is withing a large sound range as opposed to most speakers which are measured at being able to reproduce them with +/- 3db or so reliability. So no only are there gaps in the sounds being produced, but also the variability of the sound is 3 X what is expected from other speakers.
In the end, though you have to be happy with your speakers. If you decide to go with Bose because that's what you like, then more power to you, but these are the deficiencies in Bose speakers, and the suggestions you've been given correct those to a large degree.
