I thought it was only good if it had shiny labels on the front saying it had at least 200w per channel x 9.8 and the THX logo on it.

That said, I've always liked Onkyo and Yamaha.

Haha, I actually use to think the same. The fancy thx features never interested me but I got this onkyo for good price compared to other options they had. Was just surprised cause it performed better then expected. I always wanted an onkyo power amp in the past cause I heard good things about them but always stuck with sansui, Yamaha, and Harman kardon. I was going to find a harman kardon cause I heard they still stick to the dual-mono low negative feedback design in there modern amps/receivers but went for the onkyo. Onkyo seems to fellow little of same design to Harman based off what they call wide range amplifier low negative feedback method.

To derail slightly, I have a ~$400 Harman Kardon 2 channel receiver (no video functionality) and I really haven't had any itch to upgrade without spending quite a bit more. Sounds great at low volumes, too. At this point the room (and partially my speakers) are bottlenecks more than anything else.

i was actually looking at one of those in the past cause i was thinking of trying something new and was actually thinking of adding a powered sub to my speaker set-up cause harman kardon while not doing good with akg in the headphone department and not well in the speaker department they still make really good receivers and amps. around late 70's to early 80's when harman japan decided to use Dr Matti Otala theory in design(low negative to minimum negative feedback) in solid state they became well known. i mean they already were during the 70's with their ''twin power'' receivers but improved even more after using better parts and low negative feedback high current design that they still use to this day despite them not still being popular as denon,marantz or yamaha.

that harman probably does sound great. i know harman was known for making very accurate amps. i just wish they continued their success with akg but we can all dream can we?

EDIT: ohh,yea my harman kardon h/k 770 sounds super clean at low volumes as well. i think harman kardon was also know for really good low level listening that's i always wondered if they always ran in class A and switched to class a/b after certain wattage. i just know my h/k 700 runs fairly warm even at idle. the h/k 725 preamp does as well.

I have a fairly recent Marantz AVR. I tried in vain to get specs on the headphone out. There was nothing online. I called Marantz and even after checking their manual all they could tell me was the power was coming from the main power amp and cut back through the use of resistors. They did not know the output impedance but I am guessing around 120 ohms give or take based on other similar receivers I have read about.

The Marantz drives my AKG Q701 just fine. It is dead quiet (I have turned the volume way up with nothing playing) and can go to deafening volumes if I wanted it to (I don't BTW). At first I was concerned that the amps limitations was part of the reason for the low bass impact, but over time I have learned that is just how the AKG is. I have tried the Q701 on a variety of mid-priced SS amps and didn't really think they were much different or better. These were not close A/B comparisons. Just that after listening to my cans on other setups at meets I came away thinking the AKGs are what they are and slightly-better amping, short of very high-end or tubes, wasn't going to make too much of a difference.

the akg gets exaggerated with how amp picky it is. when i first got the k601 and 702 i was wondering what all the fuss was about. they even sounded great out of my cheap samsung galaxy exhibit phone and ipod touch with more then enough volume. i heard no difference going from a phone to speaker outs driving the kx01/02 headphones.i think the 702 has very good bass and 601 as well. just never liked them pass moderate volume listening. my 240df's and sextetts lp were always top choices when it comes to akg.

I also have a Harmon Kardon receiver (AVR 5). Probably not as powerful as the others mentioned on here, but it does the job. I've been lazy and kept the speakers on while using the HE-560 with banana plugs. Still sounds much better than through the headphone out.

I should clarify, I do not use the headphone out on my HK. Actually had a buzzing most of the time I've had it. D'oh, I'm on a headphone forum.

Probably was bad ground loop or something. I had that with all my amps at my old house. Only way I solved it at the time was grounding my amps. Or can be cables not shielded but that can be rare issue. None of my amps had zero digital connections at the time so I couldn't test out the optical theory. Have you tried hooking the receiver with optical?

I have it (and my whole stereo rig) connected to a Tripp Lite Isobar now but I haven't tried the headphone out at my new place. I don't expect it to sound wonderful but it would be nice if the hum was gone!
I'm unfamiliar with this optical theory - mind explaining? In my case I am not using the internal DAC of the HK.

well supposedly since optical is nothing but ''light'' that bounces from one end of the wire to the other it has zero interference from radio and electrical interferences. i never had noticed any difference between optical and coaxial testing digital on my onkyo. sounded the same to me. fiber optic is a weird cable but pretty fun to play with if you have laser pointers.

i only use it for my 360 cause the 360 crackles or distorts in certain dynamic areas on analog. some reason using my current onkyo's internal cirrcus logic dac via optical cleans up the sound. other then that i always use analog unless for console use. even had it with my stereo amps unless i used my echo audiofire interface as a transport but i like to keep my interface hooked to my computer or laptop so....

but yea, since optical uses light instead of electrical signal like typical cables it's completely immune to interference.

It might be immune to some types of noise, but the fiber optics channel can be harsh. Specially consumer grade multi-mode fiber optics which can suffer from modal dispersion. I wouldn't worry too much about it for a few feet though.

One of the issues with headphone outs of consumer level AVRs or receivers as I understand it is that they tend to have a somewhat high output impedance. But I hear that is less of an issue with planar magnetic headphones. So I was wondering if a decent AvR or receiver would be Ok with an hifiman or Audeze.

ultrabike · « **Reply #49 on:** September 24, 2014, 03:41:19 AM »

Well, mine might power some HFMs and Audezees fine... but for the HE6 one might need to do something clever out of the speaker taps.

I say that not because of experience (Ohhgourami has such experience though), but because an HE-6 requires about 19 mA to get to 90 dB SPL, and my receiver seems to only be able to provide about 17 mA out of the headphone jack (and cough blood in the process)... Don't think the speaker taps have that limitation.
