i bought a few AudioQuest cables from
@F208Frank recently. Diamond aes/ebu, Fire xlr and Dragon hdmi. haven't tried the aes or xlr, but did get round to inserting the Dragon hdmi between the wavelight server and dac.
The Dragon hdmi is very impressive.
I almost never use i2s nowadays, always preferring the aes/ebu connection. I only use i2s when dabbling with hqplayer, but ultimately always go back to redbook and aes for a more dynamic, musical, and fuller sound.
Dragon hdmi between wavelight server and dac is really nice. without upsampling, I already get a fuller stronger low end with a bit of bloom, audibly more low end extension/subbass, and slightly pronounced midrange. with the wavelight server upsampling pcm to the dac, I get all of the above plus seemingly better central imaging, a bit more spaciousness up top. with some music, elements that are slightly off center seem easier to pick out and hear, less gelled to the centre.
It's pretty easy to compare the connections as both cables can be hooked up simultaneously and the change can be done easily via the rockna app.
The hdmi + upsampling is giving the aes connection a run for it's money. I like the Dragon a lot and have already sold my Tubulus Concentus V2. downside is the AQ cable is quite stiff and rather hard to route, and of course the cost. never thought I'd go back to i2s, and am now considering paying for hqplayer5 to test out some of the newer filters.
