Salons tend to be extremely neutral and revealing speakers, especially if the equipment upstream from them deviates from neutral. This includes the speaker cables, interconnects, and powercords (to include AC filtration). I can hear the tonal signature of every change I make in my system whether for better or worse sometimes. Wilson WP 7's are definetly a more musical speaker if that is what you are looking for. Realize then you are limited to a musical sounding system because you have elected to deviate from neutrality by your speaker choice.
I power my Salons with an Edge NL-10 and Harmonix Sophisticated Listeners Choice speaker cables (single wired only using Harmonix Max Jumper instead of the factory jumpers) and this is a perfectly sublime match for them. I have to agree the demo pair at the dealer had Levinson amps and Transparent cabling and I was not very impressed with the sound. These speakers are thorough breds that require very careful system matching and set-up to achieve the stellar sound they are truly capable of. But when done correctly will provide the truly exceptional bass that is tonally correct, tight, fast, and extended if it is in the source material. They were voiced for neutrality, not musicality, so if your not willing to system match and lean toward the musical look into the WP 7's.
