The Sophia is by far the more forgiving of the two speakers. You're equipment is well up to the task of working with either speaker, but on less-than-well recorded material the Sophia probably will sound more listenable, especially in the treble. The WP also is a bit harder to set up optimally; it's very revealing. Bass might also be a little fuller with the Sophia, again not a bad thing with classic rock. Since you liked the sound of the Sophia, I would suggest going with it.
Wilson Sophia 2 or WP 6 ?
I know this topic as been much discussed but I would like to ask this specific comparison. The Wilson Sophia 2 and the Watt Puppy 6 are both going for around the same price on the "pre-owned" market. Around $8K. This is the limit of my price range so I ask those who have heard and or lived with both to comment on the differences. I have hear the Sophia 2 and really liked it, but I do not have the ability to audition both side by side. I listen to mostly classic rock (Floyd, Wings , Stelly Dan, etc) So not really concerned with the bottom octave or an organ but more with the authority of a kick drum recorded on old analogue gear way back when I was young ! They will be used with Audio Research CD3, LS26, VT100MKII. Transparent Ultra Bal cables and Shunyata Hydra and PC. I imagine the mid-Hi section similar so what is gained or loss between the single 10" woofer vrs the 2x8" ? Thank you
