So many here seem to be fixated on cost rather than value when it comes to DACs. Value can be difficult to determine when it comes to DACs since the technology is not as mature as vinyl, tape, speakers or amplification. I don’t see vintage 30 year old DACs going for big money. Changes in digital technology appear to be leveling off, but who knows until we look back 10 years from now. Still, many DACs have more value than others. It is not just about cost. Performance, reliability, adaptability and pedigree (well known manufacturers) affect market value both as a new and as a used unit.
Someone may purchase an $1100 DAC and be pleased as punch with the sound. After comparing some $600 DACs and $2500 DACs this purchase seems to be the best all around choice without breaking the bank. In 5-10 years this DAC might resale for $50-$100. Another person found his ideal DAC and paid $11,000. This DAC, from a well known brand- and that certainly adds a little to the cost has a beautiful sound with a large airy soundstage befitting the rest of his high end stereo system. In 5-10 years this DAC will likely fetch $5000 on the used market, baring any new significant technological breakthroughs. Remember, high end turntables were selling for very reasonable prices on the used market from the late 1990s to about 2010. Wish I had jumped on my dream turntable back then. Point is that both DACs have a cost of ownership and that is the thing to consider. So now, the person who snatches up the $11,000 DAC used will likely enjoy his purchase immensely with potentially a lower cost of ownership than the person who bought the $1100 DAC new. And if that is the case is there really any debate needed about the sound quality expensive DACs vs inexpensive DACs? (Other than someone must pony up the price for new gear.)
