To focus a bit in regard to the OP, has anyone compared Metrum Onyx with an Antelope Zodiac Gold Dac w/ Voltikus PSU?
I realise there's a major difference in cost when buying either of these new but i'm looking in the used market predominantly and there are so many options of various dacs in the 1k - 3k ($ or GBP) range which appear to be bargains when considering their new cost.
Is the Onyx a giant killer in that context? Are there others I should consider? Lastly where might a Jolida Glass FX Tube DAC, latest version, maybe with mods, come into the frame here and how would it compare (at much lower cost used) with the Onyx and/or Antelope Zodiac.
Any insights, experience, observations would be most welcome.
