I purchase my receiver in 2014, and it still works great.

Works great with my old turntable

Nirvana! When matched with high resolution speakers that are capable of producing an accurate and detailed sound stage. I've been a fan of H.K since the 70s., i am so pleased that Hk has managed to maintain the accurate and pleasing musicality that separates HK from other manufacturers. The H.K sound is 100% listener fatigue free with the right speakers. Bravo! HK !

Simply the most musical sounding receivers ever!

I was concerned about this receiver since it was made in China. I purchased the HK 3770 in 2014 and no issues at all! I'm very happy with this receiver. It's connected to an old HK T45C turntable, Infinity 112 speakers and it sounds great.Purchased the item direct from HK. The representative answered all my questions...he was vanastic.

Great system

Don’t waste your money on this stereo amplifier. It’s bandwidth is terrible. It’s power is quirky and it weighs less that 15ibs. Don’t waste your time with this. I don’t know what harman kardon was thinking. Harman kardon is feeding off inexperienced/newer stereo people who don’t know good from bad. Stay away from this.

Older 3490 and even 3480/3485 are 10x better

Wasnt impressed at first,.  Bought some 6 ohm polk audio t50 speakers and it really came to life,.  Good match,.

Wish it had tape loop for equalizer

I have been a loyal customer of Harman Kardon since the 1970's.  HK ampifiers simply sound the best.  They do not "offend" or "fatigue" the ears like other solid state amplifiers.  I would like to see them offer a more powerful version.  Guy C.

For the Discriminating Ear.

I’ve had this since 2015 and just today I was listening to some records and it just switched off 3 times and the third time I noticed a lot of smoke coming out and burning smell of plastic. I wonder if this is a common problem. I have no idea what to do next.

Everything was nice until today..

I've had HK products for years. Bought my first one more years ago than I care to think. I have 2 HK receivers: HK3770 and HK3490. NO problems whatsoever over the years. The sound is simply fantastic. Awesome bass (no distortion) and crisp highs. Great receivers at a great price.

Just Awesome

I'm using receiver for a year for music, home media, gaming.
It is a good choice for those, who do not plan to build home-cinema and 2.0 or 2.1 is enough.
I'm using receiver with lots of sources (bluetooth, opt, online radio) with a pair of Sony SS-176E and it sounds really good!

The only thing I don't like is a remote control, it is unfriendly.

Very good stereo receiver

So many reviews on receivers lack details about sound characteristics.  I have owned my HK 3700 for about six months ; so I know it is broken in.  I play the receiver in to Tannoy 613 towers that I have owned for 20 years. These are 6 ohm power hungry soeakers. The receiver fills up a 20 x 15 ft room with cathedral ceilings quite nicely. The HK 3700 has a very warm sound with low distortion. This receiver can be played at high volume for an extended period without hurting my ears. The sound stage is good when listening to compact disc; obviously better with records. While the distortion level is low the sound could be cleaner. My only complaint is that the sounds could be cleaner. But the trade off 
with warmth is worth it especially for the price.

Sound

Back in the day I owned an HK 640. Outstanding warm audio, square wave design.
Now I have it again with the 240 watt HK3770, plus the Harman Volume feature for DVD audio in stereo. Thx.

Old school analog - digital compatability

I bought one a yr or so ago for the living room, connected to a pair of Cornwall’s. Sounds awesome. Had to have another for my workshop. Very nice sounding receiver and plenty of power!

Great amp!

I used my first HK until it was used up. This one has more power, more headroom and more features. I love it.

My second Harmon Kardon reciever

I was supposed to receive the SABRE SB 35 not the HK 3500. Returned it and am still waiting for my SABRE SB 35

Sent wrong item

Just set this up, super easy; remote is a little hard to figure at first but is solid. The sound this thing reproduces is clean, rich, good lows, solid mids. My setup is 2x JBL Studio L890 towers and JBL Studio Sub 250P. It can push some some serious power and the Harman Sound button is a nice feature.

HK 3770 is the Bomb!

I bought the HK 3700 stereo receiver not long ago but I don't know why the remote won't turn the power off to it. It won't turn it on or off could you please let me know why I'm having this problem? Thanks

Nice Receiver for the price

Bought my HK 3770 about 2,5 years ago, the first was DOA. Went back to the shop kinda angry and got a new without any problems. The second worked fine until last night, tried to turn it on, got the message "your device is switched off" then it shuts down blinking orange. Tried turn it on 3 times then a little "puff" and some smoke followed by the foul smell of a burned capacitor. 

Looks like they have some quality issue, i thought an amplifier from a company like this was suppose to last longer, don't know if it has something to do with the "made in china" stamp in the back. 

It worked fine those 2,5 years, but this was really disappointing. Now my house is quiet and i can't afford a new right now so.. where did i put my books again, i know they are here somewhere..

Been a HK fan since my AVR 80 ages ago... BUT

This is a superb amplifier, goes extremely load with no distortion paired with my kef Q350 bookshelf speakers.
I like the USB port from which I'm able to play music from my apple device and the built in DAC is pretty good.
My only complaint is that the DAC does not seem to support gapless playback.
Overall great value for money with features found only in higher priced amps.

Fantastic Amplifier, great value for money

While this receiver has plenty of inputs and power, I am underwhelmed by the range of adjustment on the bass and treble controls.  I also expected a mid-range control but no dice.  The lettering on the front panel is too small and the remote takes some time to learn.  I have not used any networking features as of yet: not sure if I ever will.  I expected more from HK.  I used my HK385i analog receiver for about 30 years until recently when one or more electrolytic capacitors failed in the power supply.  I am contemplating refurbishing it.  It just sounds better.  It's warmer with a wide range of tone control AND it has a Loudness button.  Newer doesn't mean better.

I purchased the receiver a few months ago and wanted to share my pleasure with it. I am using it to drive a pair of PSB Synchrony II bookshelf speakers with a load of 4 ohms. The receiver drives these speakers with ease and sounds terrific. I have downsized from a much larger system ( due to a move to a retirement home ) and have no regrets whatsoever. All and all, this receiver is an outright best buy .

Best value !!!

Box came smashed in from shipping company but thanks to the packaging it was undamaged, thank goodness! This thing is bomb! The sub out was a must have for my reciever.  Bluetooth connects perfect with my Note 8, also a must have. Ample power, great product! Missing smart home connectivity.

Everything I was looking for.

I was looking for a stereo only receiver for my bedroom.  I am very pleased with the over all performance of the 3700.  I'm in a fringe area for most FM stations and use a outside 4 element beam.  The reception beats my larger multi channel receiver hands down with dead quiet signals.  The sound from my Polk bookshelf speakers and subwoofer are very pleasing.  I bought it while it was on sale, so it was a really good buy

very good fm reciver

my device went into device sleep mode, how do I solve this problem?

I can not use the appliance any more

problems

Harmon Kardon was always regarded as one of the very good receivers to have in the 70's-80's. I'm really glad I bought this. Great dynamic sound and punch. The user interface on the front panel lacks, but it's easy to get used to the remote when your over 50!

Good Receiver with Inputs and Powerful Clean Sound

I have had HK amplifiers/AVRs since the 70's.  As happy with the Factory Refurbished HK3770 as I was with the others.  Great sound with lots of features and plenty of power at a great price.  Nice compact size to fit in tighter spaces.  I hope this lasts as long as my other HKs.
Due to the different types of source selector buttons on the remote and the way they are allocated to the inputs, getting the different inputs programmed on my Harmony 650 remote was a little tricky and sometimes takes two button pushes to select a desired input.  Maybe I will figure it out eventually.
Also did not get an Owner's Manual, just a quick start guide with the receiver but I found the Owner's Manual on-line.

Great Receiver with a Quirky Remote

Purchased this for my Turntable.  Sounds Fantastic!! Just wanted nice stereo sound and this most definitely does the trick! Plenty of Power for a small to medium sized room. Built in Phono amp works perfectly!

Love it!!

I Just got my HK 3770. I love everything about it. This receiver provides the way music is meant to be heard. I'm charmed! I rarely give recommendations.

HK the best bang for the buck

I had an older model Harmon Kardon that had the loudness button feature. This newer HK3770 does not have it. Instead, it has some other feature. Not as impressed with the prayer.

No loudness button.

This is the third HK3700 and I'm very happy with the clarity and fidelity of the sound

HK 3700

Just got the HK-3770 last week. Internet tuner is amazing. Bluetooth range is limited if you don't have line of sight. The app isn't any better than the IR remote because it lacks a display. It allows for full control but you are "flying blind" if you are not right in front of the receiver. These  are often installed in closets so the app needs to mirror the display on the  receiver. Get back to work HK!
