Do you
REALLY want to get the maximum possible sound quality out of a pair of bookshelf speakers for about $1000 or less?
For an easy and extremely effective solution that will exceed your expectations, purchase an item from both (1) and (2) from the following list:
1) Ascend Acoustics CBM-170 or Ascend Acoustics Sierra 1
2) Behringer DCX2496 Loudspeaker Management DSP or Behringer DEQ2496 DSP
The CBM-170
[1] appears to have a somewhat superior driver set and crossover as compared to the
[2] Sierra, despite the substantially higher price of the Sierra, as demonstrated by credible NRC measurements. But the Sierra has a lower resonance of the cabinet system. The lower resonance cabinet can actually result in a better perceived sound quality, despite the slight inferiority of the driver/crossover. But both have very good crossover/driver combination that offers a very good on and off axis response linearity and low harmonic distortion. You need to use a precision DSP EQ between the pre-amp and amplifier, and there by allowing custom modification of the tonal response(
which is the main difference among many good quality speaker systems of similar off axis performance characteristics, as well as cabinet resonance, which you can not modify without physical modifications to the speaker system). The E.Q. I am recommending has little similarity of what you may associate as an 'E.Q.'. This device allows for precision, subtle modifications. As well, if you purchase the DCX2496 unit, this device also allows ideal integration of subwoofers(preferably stereo) that you purchase in the future; the DCX device will also make possible custom adjustments to the subwoofer sound 'signature', due to the various precision modification functions possible with this device. An E.Q. is not nearly as effective on common non-flat, non-neutral speaker systems, and can only act as a mask; this is the typical experience people seem to associate with E.Q.. But on a speaker that is somewhat near neutral to begin with, a precision E.Q. system will allow for highly effective modification of the sound signature if used properly. I will assist you in how to use this device if you choose to go this route.
