Hi all, I am going to buy my first home cinema system, and I would desire that it was the unique one in years! I am looking for a system which sounds so well in stereo as in 5.1 configuration... After reading many magazines, reviews and internet forums -specially this forum...- I´ve reciently purchased a Harman/Kardon AVR8500 on sale for only 1800! (The recommended price in Spain is 3000) Now, I am wondering what combination would work best with this receiver. I've thouhgt on this: DVD - H/K DVD25-30 (There´s an important aesthethic reason here...And I have read that is a very good CD player too!) Speakers - Polk Audio LSi Series (LSi9-Front+LSiC-Center+LSiFX-Surround. No sub so far) Is it worth paying the difference for the DVD30? I´ve read in other threads on this forum something about that... Someone in the forum has tested the LSi series? I only have seen the positive valuations for these speakers. I also would like to mount bookshelf speakers for the front channels and dipole for surround, because it isn't a very large room and the rear speakers have to be mounted with less separation between them than the front ones. Also the sofa is near the rear wall. ¿Is this (in this case) the best option? Is there any problem with the AVR8500 working with 4 Ohm speakers? I´ve seen that other manufacturers as Mordaunt Short or Jamo have similar speaker configurations, with dipole surrounds. Are the Polks the best deal for my H/K? Well, that's all, I think. Thank you very much for any help.
