Post Subject: Shelter 90X: mystery resolved?Posted by Romy the Cat on: 5/10/2005
After all, I have learned that there is deference between the 901 and 90x. I wonder why on one “reviewer”, dealer or distributor were not able to explain the differences. Also, form this table it is very understandable why many people with metal ringing tweeters having huge resonance around 30Khz (Courtesy to Utopias, Wilsons, Karhmas, Avalons and the rest HF crap) suggest that 90x cartages is “more musical” and has “smother upper midrange regions”.
