Paired with a good set of loudspeakers

DanoRoo, Amazon

  • Summary: If you're reading this review, it's very likely that music is important to you. Paired with a good set of loudspeakers, this amplifier will supply it in spades! The HK 990 is rather unique in the world of 2 channel integrated amplifiers because it combines digital functionality with high quality...

Outstanding! And now a collector's item....

jplattet, Amazon
30 July 2014
  • Summary: The only downsides here is that Harman/Kardon has discontinued this outstanding product, and that the owner's manual is next to useless. The manual wasn't a huge pitfall for me because if one can set up an AV receiver (and I can) then one pretty much knows what to do.

What Manual!

  • Summary: Nice amp but the instruction manual is by far the worse I have ever seen in my life.Harmon Kardon has a good reputation but on this alone it was a big Flub.They may as well have left it out of the box.

  • Summary: The look and the sound lives up to the hype, it's exactly as Harman/Kardon describe it. This powerhouse HK990 Amplifier has all the options you could want. My love of old vinyl records has been taken to a new level... I didn't think it possible!

defective

  • Summary: As soon as I turn it on...with nothing connected to it, goes straight into protection mode. Second model did the same thing. Terrible Q&A.

Turn on the Amp and let it disappear in the music

Yoniyama, Amazon
26 December 2012
  • Summary: Bought this amp for about a year now. This amp is used to play CD (and SACD) by a Sony SACD player (scd-xa5400es), driving a pair of Gallo Ref 3.5. Typical of a dual-mono amp, which has two transformers (one for channel), the sound is very smooth.

A super unit... with the right speakers

Neil Heller, Amazon
18 December 2012
  • Summary: This unit is really SOLID at reproducing sound. Beware if your speakers only cover up to 20k Hz., however. This HK unit puts out well above 20k (that's the first harmonic of only 10k) so speakers that can only handle up to 20k have a tendency to clip resulting in distortion at higher frequencies.

A tale of two units,it's not good

ferguson, Amazon
2 January 2012
  • Summary: I have a 2.1 stereo system so when I read the reviews for this amp I thought it would add several features missing from my system. I was looking forward to the built-in dac and room correction most but the added power also interested me.

FIRST 24 HOURS - **updated**

Amazon Customer, Amazon
10 December 2011
  • Summary: If you're not picky about your audio - don't read any further. If you are seriously considering this amp you probably are a pretty serious hifi enthusiast anyway. I just received the amp yesterday and have spent several hours of listening with it.

HK 990 is a True Audiophile Amp - Amazing!

Marc M. Mamiye, Amazon
15 November 2011
  • Summary: I dont write many reviews, but im compelled to do this one since im so impressed with the HK990. I recently got into Hifi about 6 months ago. Like anything i do, i get a little obsessed. I went and bought an NAD 375bee amp for about 1300 dollars. It was ok but I It wasn't really satisfied.
