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.

There is a concept in economics that says "price rations the supply."  This is usually  brought up in a discussion about crude oil or soybeans.  However, the principle will travel.  If you manufacture 100 DACs a month and can only sell 35 of them your probably priced to high.  But if 99 of them find a new home each month, your right where you should be.

When the S.Q. of my system was very bad, i listened to my favorite best music: Bach.... It was possible to concentrate then on music not troubled by the bad sound...

When the S.Q. goes from bad to acceptable, i go on with all style and different kind of music.... The recording was not my primary concern because sound quality begins to be acceptable....

The listening habits has 2 parts linked together: concentration on musical composition, or concentration on sound quality....

The concentration on sound quality must relax with time and with a good embed audio system...Concentration on music is the goal....

Listening musical composition shift the attention and the awareness to music not sound ....Sound being no more a restraint or an impediment, music only must grab you but by way of the sound quality it is easier...

For the last years my attention focus was dedicated more than half the time to sound...

I was in the obligation to create my own audio system, it begins with directing the awareness and attention to sound...

The best way to develop sound awareness is to set the stage for listening experiments: what if i change something on the wall?
What if i put a piece of quartz on the electrical panel? What if i change the speakers and put something under it to attenuate vibrations?

Small step by small step you will develop a greater attention capacity for details perception and this new listening awareness will guide you toward the implementation of better conditions for your audio system.... You will discover that it is not mainly the electronic design of amplifier. or of dac, or even of the speakers that create the S.Q. but on par with it and perhaps even more than the electronic design only, it was what i called the mechanical embeddings(controls of vibrations /resonance), the electrical embedding of your house(the general noise floor of the house where is embedded the noise floor of your audio system) and the acoustical settings of your room...

Then you will quit the blind urge to improve your system by buying costly new promising parts... You will trust more your ears in an incremental process of listening experiences linked to some simple experiments about vibrations, noise controls and acoustic....You will read reviewers for what they are : sellers not mainly technical adviser about how to create audiophile experience....

More you will develop a trust in your ears more confidence you will have and you will learn to know the truth about audio by listening not reading about consumers products...

I have ZERO hand craft hability, and i am not a master of D.I.Y. at all but at some time if you want badly something without the necessary money you must be creative.... My way was listening and experimenting very simple thing indeed...

After 2 intense years i begin to be conscious of the 3 dimensions of the audio system way of embeddings.... Nowhere any article advise seriously people about that.... They speaks most of the times about costly products supposed to be a cure for ONE only of the embeddings....But no single product by itself can resolve the acoustical embeddings and the electrical embeddings.... Perhaps one product like the springs can help for vibrations, but even in this embeddings only one product or device cannot optimally do the job for all pieces of gear....

It is here that learned listenings experiments helped me toward my own original solution, especially with the acoustic embedding...

It is more fun to learn to listen between experiments than buying illusions ....

It takes only time.....




In a word:

Try to create the material varying conditions that will gives to you the necessary feed backs variation controls that will transform your passive hearing capacity into an active listening organ....

The room is the ear and the ears are the room, you then must learn to work with the 2 at the same time....





last word:
Some people argue that the sound memory is very short lived then illusory....It is not totally true...I dont record sound memory by itself in my body, what is recorded is the pleasure/displeasure associated with certain sounds impression, the emotion is enduring not the sound memory by itself....I remember then not the sound directly, but my body remember his reaction to the sound and recreate the emotion like a response/habit, this is these emotional responses that are encoded in my body and that will serve me like some steps in a feed back loop of learnings experiments....

Then learning to listen is learning also to retrieve in you some past emotion and recreate it....You then became active participant in your own  hearing transformative process, not only a passive ear that recorded external facts....

There is no more pure external  facts only (sounds);  there is music, where any sound is a unique emotional conscious experience....

 

@ovinewar I appreciate your comment, concerning the division between the search for "truth" and time protected for enjoyment. More and more I see the limits of endless searching, which seems to be pronounced in a commercial culture, where our desires our endlessly pricked, to the point of inflammation.

Perhaps our thread has burned itself out... 

Much appreciation to all contributors. If you have final thoughts, please send them along...
