Harman Kardon AVR 7550HD Flagship Receiver

[AVDOCTOR]

I'd like to get my hands on one of those, to replace my AVR 635

Me too! I'm on Disability now, though, and the cash doesn't compare to when I was working in the A/V industry. I took a killing on my AVR 500 to step up to the AVR 635 primarily to get component video switching ( instead of s-video ),with practically the same amplifier. This, in my thinking, is the only reason to own a Harman Kardon instead of a competeing product - they SOUND better, and its really that simple. As soon as I sacrifice a couple month's income, it would be nice to know that the scheemers in the business don't already have something to replace HDMI with!

I have a HK avr 25 in my living room.

Along with Marantz. I've got a 10 year old 880 I'm still using in this room for a 2.1 system. The problem with this Marantz is no real bass management, only a single xo point @ 100htz.
I don't know if the newer Marantz are as good, now they're part of Denon.

As for my HK635, the auto setup/eq has stopped working, as far as it doesn't "hear" the pink noise. It will send pink noise to each speaker, but then give me a message that it didn't happen and to check the speaker connections and try it again. And its not the mic, I checked it with a VOM.

I will put my stake in and say it will be a monster of an amp. I have an older AVR 7000 rated at 110W in stereo and 100W while in surround. I have been powering a pair of MB Quart QLS 1030's 4 ohm 87 dB and this reciever had been pushes as hard as you you can push a reciever and it has never gone into protection mode. I just bought the Onkyo 805 and it is a strong amp but nothing compared to the HK. I am a HK believer for life. Maybe I will pick up one......two.....

HK and NAD know how deliver on the amplifier sections, thats for sure.

well thirsty the avr 25 i also have its now in a box and dont use it cause i have the avr 635 w/out the problems people have but yeah that thing has good sound. And is it just me but i was looking at the avr 7550 manual it states the sub crossover stays at 100 hz wtf on every harman ive owned i can change the sub crossover and also when did harman start rating there recievers driven in 2 channels vs there ALL CHANNEL DRIVEN SPEC like the 7550 says 110 times 2 channels driven and does anyone one now what kind of power capacitors this reciever has ?

[allargon]

HK power isn't in doubt. What drives me nuts is their video processing (Yes, I know Denon also uses that garbage Faroudja in their lower end receivers, too.) and room correction feature set on many of their receivers seem to be stuck in 2004.

HK, NAD and maybe? Cambridge Audio definitely deliver in AMP. I do love the HK sound of my little AVR 247. I'm not in love with the video processing or other feature sets.

All that said, it's nice to see HK filling out the space between HK and Lexicon. (No, they're not bumping up into Mark Levison territory at all. Truthfully, HK could offer a pricier separate and still not get to Lexicon let alone ML territory.)

BTW the 7550HD is now on HK's web site. (Notice that it doesn't even have HDMI 1.4.)

Also what kind of DAC's (assuming it's different than the TI DSP) does this puppy use?

I am repeating myself but I honestly don't see much value to have any video scaling processors on board receivers at all. If HK sticks with the stupid Faroudja because it costs them next to nothing, then I said they are just being smart. IMHO money saved by not having onboard video scaler can be better spent in improving other areas such as power supply, noise reduction, more HDMI and top quality video signal pass through etc. Most HD players and TV have decent scaling capabilities and if more people rely on the TV's build in scaler it will give their manufacturers incentive (competition) to improve on that quality, instead of putting REON/ABT etc. on receivers and HD players that often go to waste. I lost count on how many ABT/Reon and others in my system it is getting ridiculous.

I think the biggest scam going more so than this upscaling is 3D. Another useless fad dsigned to suck money out of the general consumer. I'm telling everyone I know about the assoicated health risks and I recommend against it to all I talk too.

Having the video processor within an AVR has many advantages...
A typical home theater system will have a wide variety of sources connected, each of these sources requires different video post-processing modes.
The video processing modes may include:
a. NR
b. Edge correction
c. Film edit
d. Aspect ratio
e. Gamma gain
f. Sharpness

Connected sources could include a PS3, cable box and a digital camera.
If one expects the video post-processing to be done within the video display, then every time one switches to a different source they need to go back to the display's OSD and change modes...
As when the AVR is connected to the video display through HDMI, all modes within the display are applied globally to the single input from the AVR, a major disadvantage...
For example..

• On the cable box, one is watching a movie so he wants the film-edit mode ON.
• On the PS3 one is playing games so most of the post-processing modes should be OFF
• On the digital camera, one will likely want to adjust the sharpness and gamm gain controls

Perhaps in the future when all sources are HD, there will be less need for changing video post-processing modes, however in today's SD and HD world these mode changes are frequently required.

Regarding choice of video processors, this now comes down to the marketing game which is better..
Anchor Bay, Marvel, ST, TI, Reon..
Just like which audio DSP or DAC is better..

Just my $0.00..
