Benchmark Dac1 vs Ack dAck

I own the aCK! and I can say after owning the Classe DAC-1,Theta GEN Va and the Dodson 217 MKII that it is the best DAC I have owned.It is very open, smooth and has the least glare and fatique of any DAC I have heard.Good luck. Mark

Get hold of an Ack! dAck! is what I say. The thing that realy stood out for me was the immense improvement in dynamics, making music come pretty close to 'live' music. Relatively low price, built like a tank. Shame about the long waiting list, but quite understandable.

I just finished auditioning both of these, and the punchline is, the Benchmark went back for a refund and the ACK! is staying!
The Benchmark is a great DAC, no doubt - I can see where it garners rave reviews. It is highly detailed, very transparent, very exciting listening. But after awhile, its relentlessly detailed presentation gives you the proverbial digital headache. I started listening less & less. It would be great for studio use though.
The ACK! on the other hand reminds me more of my trusty VPI turntable and records - everything's there, and everything just sounds right, just like music should. No glare, sweet but not sugary, nicely balanced, dead quiet. And, you can listen for hours on end - you have to drag yourself out of the listening room because it's time to go to work. Bonus - it's half the price! Worth the wait.
In my modest system - Quicksilver monos, B&W CDM NTs, McCormack passive pre - it was no contest at all. Good luck & good listening!
