A B&K 507 is a real piece of technical sophistication. I didn't like them because programming them could be quite an exercise in discipline and to change one setting might force you to go through five layers of programing to change a parameter. Yamaha, Marantz, Denon , and Mcintosh the simplest. . I did like the configuration options. I really like the 3.1 mode. They had options only Lexicon could match. The surround modes were much more natural than Yamaha and Denon for instance. But you have to find some one out there that can help you step by step. Remotes are available from Universal remote that will operate the 507. I don't remember the model number. The units are very sensitive to heat and need to be cooled and best kept cool to the touch. We had to return at least a dozen units to the factory for repair as they felt dealers were in capable under warranty. Even when all issues were listed , not once were the units returned fully operational when returned and had to be returned for further repair, which didn't make customers happy. Ex changes were made in some cases. The amps and separate stereo preamps had zero issues. The 507 on the other hand was about a 50/50 split. After few years we had to give up the line. Yamaha, Marantz, and Sony ES were are popular lines. Maybe some one can help you ought. That all said they were great sounding units that outperformed the Japanese units. Combined with M&K speakers resulted in a state of the art system. Another choice I preferred over Oriental units was NAD. But here again its very important to keep NAD units cool to the touch for long term operation. Japanese take abuse better it seems. I'm a keep simple stupid guy and prefer a unit that doesn't depend on a remote control. So being a Mcintosh owner since the 60's I'm a Mcintosh owner today. Fortunately the factory is still in business and folks like Audio Classics are here to help us out. If B&K had believed in service after the sale like Mac they might still be in business.
