I decided to keep them. I had a few listening last night and the sound is certainly a welcome addition. From memory I prefer the HD800 but I never had the chance to A/B the both and most importantly that HD800 was connected to a 5K dac/amp which certainly helped things. I might be able to get the entire setup organised by end of next year but it is something to look forward too. I think it will stop me getting distracted and just focus on the rest of next year.
