I just purchased a Sony CDP-710 CD player. I warmed the unit up and plugged in my headphone amp. I heard sound on only one channel. Same thing when I plugged my headphones directly into the player's headphone jack. I opened the unit up just to see if there was something obvious, like a loose...

I just obtained a QED MB-45 to drive my AKG k501 phones. I've read various opinions about it, but I was happily surprised at how synergistic it is with my k501 phones. It really has the voltage swing to make these phones sing and has a whopping bass I'd never heard before. Anyone else tried...

I just found and purchased a Sony D2. I own a D555 but I couldn't help but pick this one up. Anyone played with this one extensively? Is it one of the classic pre-anti-skip/maximum battery life PCDPs? There's a long thread in reviews the promises and update including this player but it's never...
