Trying to power vintage Polk SDA 2's. Also have a pair of small Maggies that I'll use too. Both these speakers require a lot of power to perform properly I'm told. On a budget so can't get crazy. In my area there's 4 receivers for sale that may do the trick. They are: Harmon Kardon HK670 Sansui 4000 Nad 7175PE Lafayette 9090 Which receiver would be the best choice?
Thanks for all your input. I've looked at some new stuff and the Yamaha R-S500 and the Harmon Kardon HK 3490 look good. Which do you think is better of the 2 and would it be a better choice over the vintage stuff?
