I have an HD 800 S and absolutely love it! Upgraded from HD 650 and man what a huge difference.
Right now I am running a Burson Conductor SL 9018 and although it seems like quite a nice DAC + AMP, I can't help but feel the 800 S can do a lot more. Especially since when A-Bing between my motherboard sound card (which has a amp+dac built in) and the Burson I only found the Burson to be slightly better.
My budget is up to about 5,000 $ total but less would be great.
For Amps I'm thinking of the Simaudio Moon neo 430 HA, Ragnarok, Master 9, Auralis MK 2, headamp gsx Mk 2
For DACs I'm thinking On board DAC of the 430 HA, Yggy [Im leaning heavily towards Yggy], Master 7.
Any thoughts on these or votes for any other options?
