If you love the sound of older players then hold onto your current Sony. Newer, good, models are more precise, have lower jitter, tighter timing and things that comes along as technology improves. But not everyone likes pinpoint imaging or starting and stopping on a dime. I do, but you seem to favour a full round sound. While the Gungnir is quite a bit warmer than my PWD2, compared to the Sony it's going to be razor sharp.
