After losing my Denon AVR 1908 receiver to an unanticipated electrical fluke (buzzing and turning off) issues, I searched the internet for a replacement. I read numerous reviews about other Denon and Home Theatre receiver customers who had experienced similar electrical issues after unreasonably short receiver lifetimes, so I decided to give up on the 7.1, 5.1 Home Theatre Hype. The sound my Denon pushed to my vintage speakers was mediocre and not very pleasing to the ears. I decided to search for a good old analog 2-Channel stereo to push my 1974 Klipsch LaScalas and 1970 Klipsch Heresys. After a couple of minutes of searching I found many reviews on the Harman Kardon 3390 and 3490. Because my speakers have such a high sensitivity db rating, I decided to go with the 3390 which cost 209.00. Four days later it arrived at my home. WOW! What an unbelievable sound that this receiver delivers; crisp highs, warm midrange and an unbelievable sub output. It is the closest sound I have ever gotten to the old school tube amps. I definitely would recommend this receiver to anyone who is searching for the perfect 2 channel receiver for your vintage speakers. The two sub outputs are just a bonus.
