Last year I sold my HD800s to fund the purchase of a Lavry DA11 DAC and now have seller's remorse lol. It all began when I bought a pair of Linn Kan speakers at the start of last year and because they're bass-lite, neighbour friendly and fun to listen to, I pretty much stopped listening to music via my headphones because I could play the Kans semi-loud just about anytime I wanted to, even at night, and so thinking I no longer needed the HD800s, sold them and bought the Lavry DAC. Wait, there's more... A couple of weeks ago, I sold my NJC Audio Monitor II headphone amp because even though I still had a pair of HD650, I wasn't using them and thought I might as well sell the headphone amp and if I really want to listen to music via headphones, I could just plug the HD650s into the headphone socket on my Lavry DAC. I did this last week and OMG, what an experience. I wouldn't say I now want to listen to music via headphones all the time, but I now wish I'd kept the HD800s because it turns out, the Lavry is an excellent headphone amp as well as an excellent DAC. The HD650s sound pretty good via the DAC, but do seem a little overblown near the bottom end and I reckon if I still had the HD800s, I'd have the perfect amp for them as the DAC seems to give a bit more bass than the NJC did, which I reckon, would be perfect for HD800s. So, I now want to buy another pair of HD800s, which is good becuse they're great headphones and I think the DAC will be a perfect match, but bad because it means paying top dollar for another pair, doh!
