For work setup I've used a Dragonfly Red paired with the Polaris, at home the RME ADI-2 DAC, and testeda Khadas tone board. All sound more fine w with it... the only DAC I wasn't particularly fond of the sound with was the Schiit Bifrost. I would just go with a $100 level DAC like the Khadas or equivalent and call it good unless you can and want to spend the money on an RME ADI-2 DAC.
Thanks. RME definitely out of my price range currently, but maybe one day it won't be..
I reached out to Jeremy at Garage1217 today about the Polaris. He said worth trying the Polaris from PC soundcard to the amp via line out to see how I get on with the sound.
Garage1217 do not officially recommend dac's but Jeremy did say that they find the ifi Zen Dac pairs very well with their kit. I may give that a go.
I'm returning the Fiio K5 Pro tomorrow (leaving me without a dac/amp temporarily) as I've never been truly happy with the sound signature it has. It's too neutral for me, I prefer more warmth.
With my Denon's arriving tomorrow, I now need to quickly decide whether I plump for the ifi Zen Dac from Amazon, or, try something else. I am not impressed with it being £50 for a 5v mains adapter for the ifi Zen though :-o
It will be a few weeks before I have the money to buy a brand new Polaris so need something that will be a dac and have enough grunt to power the AH-D2000s until my Polaris arrived.
Whatever I get to replace the K5 Pro, I shall need to keep for a while. I'm hoping the Polaris will be good enough for a year at least...
Depending on how I get on with the Denon's, I may sell my X2HR, in part to fund the Polaris.
Aargh the head-fi merry-go-round continues lol!
