Integrated amp: VAC, DK ref, Ayon Sunrise or Karan

Not familiar with Ayon or Sunrise (Chinese perhaps?) but I am familiar with DK and I know of the reputation that VAC gear has. I honestly have never seen anything negative written about any VAC integrated (from the press or consumers) and that's rare in this industry. Sonically they have a stellar reputation in the audiophile world. You pay for that performance however, they are rather expensive. Since you say cost is not an object, out of those 4 choices my opinion is go with one of VAC's intergrateds. DK makes some very high value high performance hybrid intergrateds but VAC tube integrateds are in another league. You asked for an opinion, this is mine.

I think you need to be more specific about your needs before anyone gives you a recommendation. For example, what are your speakers, room dimensions, music tastes and preferred volume in listening? These are just a starter of questions I would need answered before I would even try to make a suggestion. I personally have a VAC amp and I'm very happy, but my amp might not be appropriate in your system. Do I make sense to you?

The speakers are Magico Mini, and the digital gear is EMM labs
