Selling a very rare modified Harman Kardon HK990 Integrated Amplifier. Lightly used, it's an absolute beast and certainly by far the best integrated amplifier ever made by HK. This amplifier was Sidney Harman's pet project and last attempt to bring true HiFi back to the Harman Kardon brand.
This particular unit was modified by Stereo Dave's here in Portland who specializes in HK modifications. His mods have received excellent reviews (see link below). A Stereophile's B Recommended component and 2009 EISA "AMP OF THE YEAR" in stock form, this modified unit is really something special.
I've owned two of these units - one stock and this modified unit. There is simply no comparison. The modified unit offers an enhanced musical presentation- better in every way. Extended airy highs, more tightly focused bass, and a mid-range to die for. And the stock unit is no slouch. It has power and grace in spades - you simply will not be disappointed in its performance. I've also compared modified unit directly with a Rotel RA-1570, Plinius 9200, Modwright KWI-200, and Luxman L505UX integrateds and easily kept coming back to this unit. I'm selling because I decided to go the tube roller route. I had to spend several thousands more on separates to beat it - namely a Primaluna Dialogue Preamplifier and Benchmark ABH2.
This amp built like an absolute tank at nearly 50lbs. True dual mono with 150w @ 8ohm doubling to 300w @ 4ohm. Input definable balanced inputs (that I used for my DAC). HT/ Pre-amp by-pass. HK even provided 2 separate phono stage inputs - one for MM and a separate input for MC. All functions work flawlessly including the DSP/ room correction feature. You can choose the enhanced digital route or bypass and go direct analog.
The unit is in excellent condition top to bottom - very well taken care of. Comes from non-kid/pet, non-smoking home. The remote, calibration mic, power cord, and PDF copy of the manual will be included with the original box. I will also include the original receipt from Stereo Dave's.
You will be astonished at the performance of this amplifier especially at this price point. Please reply with questions. All reasonable offers considered. Thanks!
