Pioneer introduced the A-91D Integrated Stereo Amplifier to the American market in the latter part of 1987.  (The A-90 Integrated Stereo Amplifier with different voltage requirements was introduced in England, Europe and Asian countries; see the separate listing for the A-90). 

Pioneer offered the A-91D in the Elite line because integrated amplifiers were still a significant portion of the consumer electronics market and audiophiles appreciated the A-91D's convenience, as well as sonic performance.  Buyers could choose to add the F-91 Tuner to their system if so desired.  (It would be several years before Pioneer would offer an ELITE receiver.)  The A-91D was rated at 120 watts per channel into 8 ohms.  THD was a mere 0.003%.  Complete specs are given below, but among the most impressive was this amplifier's weight: nearly 66 pounds, making it one of the heaviest integrated amps on the market. 

M.S.R.P. for the A-91D was $1500.00 in 1987, but rose to $1600.00 in 1989.  It continued to be offered through 1990.   In the February 1988 Equipment Buying Issue of Stereo Review, Pioneer rolled out an expensive 16-page ad campaign for the Elite line of components with each component covered.  The ad copy and specifications from that ad are shown below.  Click on the thumbnail image to enlarge. High Fidelity magazine reviewed the A-91D in the March 1988 issue.

In the March 1988 issue, Pioneer continued the lavish ad campaign.  For the A-91D, the tag line read: "Turbocharge Your CD Player."  The full-color ad displayed the A-91D looming large, spread across both pages.  This site will run that ad copy in the near future.  In the meantime, enjoy reading the hyperlinks below.
