As a "Woozie" I'd like to suggest that for me it was simply a matter of the way my Woo was voiced, tube complemented and the system I ran. Many variables - I loved what this particular glass brought to my table. BUT, this can be said for nearly all gears and accessories introduced to one's system. What plays well inside your listening room, may or may not get my attention. It usually does though.
And who doesn't like females? I kid I kid. I'll rock any version if it's worthy to be in my system. Currently, my gear is suffering from claustrophobia.
