Hi. The headphones in my Sony DS5100s will soon be approaching the end of their lifespan. Rather than just buy another set of headphones for them, I'm thinking this might be a good excuse to upgrade. I was originally looking at Philips' much-delayed set of surround headphones, until I came across talk of Kenwood's 7100 & N8100 recievers. The combination of Dolby Headphones with TI's excellent digital amplification (not to mention that cool stuff it can do through ethernet) looks to be a winner. And once I factor in the fact that I won't need to buy a switchbox for my audio cables, it isn't that much more expensive than the Philips unit. Has anyone else been using one of these as a headphone amp? I'd love to hear your impressions and experiences with it. Thanks!
