Hello,
I just received my iFi set. And they are simply amazing. I thought I had good speakers when I had the JBL Creature II Speakers, partly due to the fact that I never had any sort of speaker system before that included a powered subwoofer. The difference between the JBL's and the iFi is amazing. I can't stop talking about them and showing them off. I am not a huge audiophile, very new to the scene, but eager to learn. Are there any good guides or FAQs out there regarding sound? It seems like a very subjective issue. Are there any "test" cd's that feature tracks that just run through the frequencies? How do I know my tweeters are working well?
