I also went for Harmon Kardon. Not sure it's worth the money but fabulous sound. I do like my music and this system is so good. Everyone comments on the sound quality. Not answered your question I realise but if you can afford it, go for HK
It does seem a bit pricey, but a wonderful system for clarity and with the Dolby logic providing the surround effects, I'd say HK all the way. Picked up my 220CDI Prem Plus AMG on weds 25th. Absolutely loving it. Ask away if you have any other questions, happy to help where possible.
