Charles Hansen of Ayre with their QB-9 asynchronous USB DAC, Stereophile's 2009 Product of the Year
Ayre Acoustics makes a complete line of electronics including amplifiers, preamplifiers, integrated amplifiers, disc players, DACs, ADCs and more. Our focus today will be on their digital side and specifically look at issues that affect file-based playback. The idea for this Q&A came about from a series of email exchanges I had with Charlie Hansen, Ayre's Founder and Designer, related to my recent post which contained a list of NOS DACs. You'll see that we touch on this topic and it was my hope that we could come to a better understanding of some of the underlying issues involved in the D/A process in general which might lead to a better understanding of why a list of NOS DACs is about as useful a grouping as four-legged animals when looking for the ideal DAC or pet. I'd like to thank Charlie Hansen for his time and very informative and detailed answers.
