I felt I was between a rock and a hard place with my proposed review of the
Ayre KX-5 Twenty preamp. If I had written anything negative about the Ayre
preamp, people would have said I was getting my own back at Charley. If the
review was positive, I would be accused of pulling my punches in order to
placate Charley. The KX-5 Twenty was eventually reviewed for Stereophile by
Art Dudley and Jim Austin.

Not quite "multiple" solutions, as Ayre's complementary filter for their
DACs is not available and the unique Ayre QA-9 A/D converter has been
discontinued. MQA, _if_ it operates as describes and as I investigated in
my article, is the only commercially available end-to end solution. (Unless
you consider very high-bitrate DSD implemented with complementary
first-order low-pass filters.)
