Introduction

Component group is:
  • harman/kardon Citation XX amplifier (220V, Serial # 01252)
  • harman/kardon Citation XXP preamplifier (220V, Serial # 01331)
  • harman/kardon TU915 tuner (110/220V switchable, Serial # 00015)
  • (110/220V Transformer available for worldwide use)

A truly rare find, this amp/preamp system is one of only a handful produced (due to their absurdly high cost) and currently hoarded by a discreet group of audio connoisseurs. It is in near mint condition; the amp is in the original harman/kardon wooden crate. It may be years before another comes on the open market. These pieces were originally owned by a top executive of harman/kardon, who bequeathed them to the current U.S. owner.

The legendary harman/kardon Citation XX power amplifier is perhaps the best sounding amp ever made. It was designed by world famous Dr. Matti Otala, who discovered and resolved Transient Intermodulation Distortion in 1970. The Citation XX was an at-any-cost project, and is the crowning achievement in amplification's sound quality.

Amp & Pre-Amp are the preferred 220V input, which is why (for 110V sources) the transformer is included in this group.

From The Vintage Knob:

“Launched as an absolute amplifier project in 1978 with the famed Matti Otala at the helm, the CITATION XX landed in the catalogs circa 1980/81 and in a few (rich, very rich) homes at about the same time. You don't see these that often, in fact you never do: Just plain mythical.”

This matched set of amp/pre-amp and tuner was recently cleaned, serviced and certified by Analogique, New York City's premier audio service systems laboratory (they are guaranteed 100% to original specification). PDF copy of servicing/certification is available at no charge (see below). The amp and preamp were also cleaned and serviced by the harman/kardon factory in 1996, and a PDF copy of that report is also available to you.

While this equipment is available through a private sale directly from the original owner, dealer inquiries are welcome. Please contact Mike.
