I have a Bose AM15 speaker system. I intend to buy a new receiver very soon. The dealer advised me to get a high power-output receiver to fully enjoy bose. I have narrowed down my choices to Marantz SR-7400, Denon AVR-3083 and Yamaha RXV-2400. I would be pleased if you can provide me with further advise on the which receiver you would recommend. Thank you for your help.
The receivers you mentioned are all excellent receivers. And your choice will be a matter of which features you want. But none of these will improve the sound of your Bose, no matter what your dealer claims, because a high powered receiver cannot breathe life in to a dead speaker. Just my opinion, I own Bose equipment and my kids and wife love them, because they are so small and unobtrusive. I just can't recommend them, decoration, yes...listening, no!
I have the same Bose AM15 speakers and use them with a Harman Kardon AVR 330 and the sound is warm, full and smooth, with enough detail. I really like the como. The HK is easy to use, is well built and has a good AM/FM section with good reception.
