I have. I bought 2 HK's the 220 & 110. The 220 works fine for now but the 110 is crap. Tandy/radio shack can't fine out whats wrong with it. The front stage is all messed up. First the center channel goes out,then when I get it back from Tandy 2 days later the right channel goes out,then after it's is so called fixed the right channel goes out today. NO MORE HK'S FOR ME!!!!! From now on Pioneer,Kenwood,Yamaha,Onkyo,Panny or Sony. I had to make some changes to my choices. Denon is out also.
