What makes a DAC so expensive?


You can buy a Cambridge Audio AXA25 25 Watt 2-Channel Integrated Stereo Amplifier | 3.5mm Input, USB Input for $225, and most DACs seem more costly. 

I'm wondering what it is that makes a Bifrost 2 almost as expensive as an Aegir and 3x's as expensive as the Cambridge product, above. I would have thought an Aegir would out-expense a Bifrost by a factor of two or three. What are the parts that make the difference? 

I'm wondering if the isolated DAC concept is one that comes with a "luxury" tax affixed. Can anyone explain what I'm getting in a Bifrost 2, or other similar product that justifies the expense...?

Thank you.

I will add you might be able to tell the PS Audio garbage from other DACs they measure like crap.

see we woke up on the wrong side of the bed this morning

sorry that being on this lil forum makes you so unhappy




If 2 DACs are to the point of transparency then how can they be told apart? You can't get more transparent, it's like infinity there isn't infinity and more infinite. 
Of course PSAudio DACs measure so bad they aren't transparent so they can have a sound  to them.
