Owner's Thread for Harmon Kardon AVR 320 325 520 525 8000

I bought the 8000 based on reviews here and it is a very nice piece of gear. I would highly recommend it to others as I am very satisfied.

I put the 8000 with a 5'x10' projection setup and Def Tek Speakers.

Now I am ready to replace the $150 RCA prologic decoder I have with my 32" XBR.

I am using a Polk Center Channel and In-Wall's for Front, Rear channel is still up for debate (currently using the free speakers that came with the RCA) some small good quality bookshelfs are probably in order. I also have a 500wat M&K in use here so I can use it for LFE & L+R. I know there is room for improvement here, but the sound quality is reasonably good and it isn't worth the tradeoff based on the room layout to replace with floor speakers. Besides the HT is in the other room, this is for more casual viewing.

I am considering another 8000 at the great deal price of $1300 but these others are much cheaper and the 8000 120watts is overkill for these speakers.

So this is what I need help with.
What are the differences between the 320, 325, 520, and 525 so I can balance that with the cost difference. And I am welcome to any suggestions that include a basis for the suggestion.

Thanks!

Feeling sorry for you, here's my take:

The 25 series has EX capability. The 20 series does not (neither does the 8000, but it is capable of Logic 7 on multichannel sources while both the 20 and 25 series are only able to do it with 2 channel sources).

The main other difference between the 20 and 25 series is 6 amps in the 25's and only 4 in the 20's. The 20 series will decode into 7.1 but you need a separate amp to drive the channels. In the 520, you can reassign the amps to power whatever you want, including a separate preamp. In other words, you could get a different power amp for the front channels, then use the 520's front channel amps to power the additional 2 rear channels, or use the power for a component in another room, etc. I'm not sure if the 320 will do this. HOWEVER...The 25 series 2 extra rear amps can be used to power components in another room and give you multi-room capability without buying another power source.

There is more power in the 500 series than in the 300 series. " 325 is 7x50 watts 525 7x70 watts.
The 525 has Digital Bass Management of 6-/8-Channel Direct Inputs
HDCD® Decoding"

There are, of course, other small differences, but the main things are:

A) Power (more for the 500 series and more amps for the 25 series)
B) EX decoding (yes for the 25 series, no for the 20 series)
C) Ability to assign the amps to external sources (yes for the 20 series, and no for the 25 series).

My recommendation: Get the 320 (? at jandrworld.com). It's more than enough for a second system. If you want EX decoding, go with the 325.

I hope this makes sense. It's 5:30 AM and I've been up all night after 5 hours of sleep.

Turn it UP!!

I agree with your decision and have ordered my 525 for $699 - plus shipping (from Costco). I have the 520 and wanted the ex capability and the 2 extra amps. I doubt my wife will allow the 7.1 to set up in our little house, but I can run wire to the bedroom and use them for music there.

If you said this I missed it somehow, so for anyone else....

A nice feature of the 525 I discovered when setting it up is that if you only want 5.1 surround it has 2 more channels of amplification that can be used for the second room function.

However I may need to try to improve airflow (On deep shelf with about 1/2" head room) because at any significant volume on the second room the entire system cuts off. Or perhaps this amp just doesn't have much power...

The rear amps should have the same power as the others. What kind of speaks are you pushin' (in the other room)?

Turn it UP!!

Varies on position at full volume they are 2x as you turn the volume down it goes up. So if all three rooms were wide open the amp should see about 5ohms. Amp was cutting off rooms turned down.

I have no explanation...
Guessing that the variations in impedence might be too much for an amp driving 7 other channels...
However, I'm just making stuff up.
Have you contacted HK???

MighTivo,

Congrats on your purchases. You are one of the few people who have both the 8000 and 525 in their system. How would you compare the two if you were just using them as a processor? Is the sound difference between the two tremendously different?

Thanks,

Mike

Sorry, tough to answer because of the setup. Not in my house, so I am not there listening to it a lot. We bought the 8000 for the great deal and reviews here. I recommend the 525 mainly because operation was similar. 8000 is in a dedicated theater area (see my .pics that I need to update) connected to some nice DefTec speakers. The 525 is in the family room driving a small polk center channel, a pair of sonance in walls (in ceiling) for front channel, a decent Velodyne sub, and some yet to be determined rear channels (currently some bookself speakers I had laying around. The theater room is carpeted, and really no way to set up a standing wavewhile the family room has hardwood and is basically a big square room. Finally, the 8000 has a new Denon DVD player and the 525 has a 2 year old cheap Apex

hey guys - i also bought the HK avr 8000 - i was a little scared coz the first one i got is a DOA and that got me worried about quality control. they sent me a replacement and WOW - this receiver really does the job - great spund quality.
i was getting ready to return it if it did not meet my expectations and if i find the center channel buzz as ppl call it annoying .
to my surprise - this receievr is excellent and the center channel buzz in almost non existent - you have to have your ears at the center channel tweeter 6 inches away to hear it.

overall for now - this is good bang for the buck - hope it last without problems-LOL.

ill probably use this as an amp later as it has main ins - maybe get a receiver with a lot of features in maybe 3 years.

Has anyone compared the 520/25 to the Onkyo TX-SR600? The Onkyo is going for very cheap now over at hifi.com.

You are comparing to considerably different priced units. The 325 vs the 700 is a better comparison. I've chosen to go with the avr 325 because of the true power, 7 channel decoding and cosmetics. The avr 325 just plain looks better.

Harman Kardon AVR 8000 no audio after reset

Just received this unit and it was working properly and decided to base-line the processor settings with the processor reset per OEM manual. The speakers and CD Input were working. It did show RESET on the panel and I heard a few clicks during the reset. When restarting the unit all appears fine on the display but there is no audio. An ideas? Thanks in advance.

Inside the 8000 beside the power transformer is a vertical PCB with fuses...
After time these have an issue of working loose, unplug the unit and pull out each each fuse. Then pinch slightly their holder for each end...

Just my $0.02...

Harmon Kardon avr 525 turns up on its own

Hello,
Wow it has been awhile since I've been here, nice forum!
Recently my HK AVR 525 has been turning up the volume, all on it's own.
This happens after we have turned in on and while it is playing.
It just started a few days ago, but has happened several times - and, since it is our bedroom receiver, my wife is not happy, haha.

Any ideas on what I could do to remedy it? Or is it a lost cause if it continues to do this?
thanks!
