so.... Same spot, same speakers, same turntable, same record... only thing different is using a Mcintosh preamp vs. the preamp in my Pioneer.... Even my wife noticed a huge improvement. We usually use Wilco -Sky Blue Sky and the Beatles -Abbey Rd. also a very nice improvement with CD and Echo Link.
I can make the claim even without an SPL meter as I have lives in this house for 11 years and know where I like to have the volume. When I bought the Klipsch I actually ran them vs. Wharfdales, KEF, Polk my old Event studio monitors and Pioneer CM77a (which sound dreadful compared to the rest). I used a JAMO multi speaker input changer. IN MY KITCHEN, the Klipsch sound the best. This was not scientific except I did put the speakers in the same spot. I had to adlust volumes as the speakers were all over the place.... anyway.... Maybe after I change my amp and maybe get another Turtable cartridge (and stores are open with inventory) I will try some new speakers.
