Sure. A Sony AV receiver will drive pretty much any headphone. However, two things to keep in mind:

a) You usually have to change your surround settings to plain old two channel stereo. If you listen to phones with the typical Dolby Pro Logic settings (and no center channel or surrounds), it will sound like ka-ka.

b) The padding resistors used to reduce the voltage from the speaker outputs to drive the headphones will have a significant impact on freq response...usually adding a ton of bass to headphones.

It's more likely to do with your Beyers though.

You don't need an expensive amp to open up HD650, just the right amp.

My cMOY drives them beautifully and only cost 60$ and yes I have done comparisons with a 300+ dollar amps.

Can you name a few expensive amps that you used with the HD-650's in comparision to your cMOY amp?

The reason I am asking because I am thinking of upgrading from my current amps: CMOY, PAPV2, Denon AVR-683 receiver to a Heed CanAMP or Musical Fidelity X-Can V3. If there is not a significant difference then I will hold off on the upgrade.

I can assure you there is a significant

difference between a PA2V2 and MF X-can v3.

It absolutely is the other way around when using a good amp to power them, but without a good amp/source the bass can totaly dissapear. I noticed this when i tested the 650 with a pro-ject mkII at a store, they where bright harsh and unpleasent to listen to (yes the HD650!). Now when my X-can is burned in they are truly amazing and my 595 doesn't get much time anymore. The bass! the soundstage! the clarity! the PRAT! the voices!! OMG!

I also thought they where boring at first (about a week ago).
It might even be my ears that have learned to appreciate the 650, but also my 595 sounds alot better from the x-can now so I think it's the amp burn in that has most to do with it.

 

[greenclaws]

You're right, I was just thinking of what was better at the time for me, and the 595 was, as the treble made it come a bit more alive.

OP, get a DIY Amp for your HD650s. An amp really makes a difference.

Reasons why i suggested DIY amps, they are cheaper, and to some extent, better than alot of commercial amps at the same price.

My suggestion for the amp would be a PPA v2 without a gain stage. Diamond buffers, 0 feedback for the win!

EDIT:
I should perhaps add this. The HD650 is sometimes relatively boring when compared to other cans like for instance the Grados, Beyers or K701. To be honest, the main reason i got the HD650 was because of the "boringness" signature. It's warm lush sound makes my listening so much more comfortable and less fatigue. The fidelity when paired with a decent amp is really amazing too.

I've seen a few people say they really like 650's with EMU 0404 USB soundcard, has ClassA headphone amp built in. I have this soundcard but my HP are 595 and not 650.

 

[cherepashka]

Soundcards and Hd 650 are not compatible

)))

 

[noobie72]

I have the EMU 0404 USB with the HD580s and MS2i and it drives both just fine for me, although I rarely go past halfway on the volume with either. That said, I only listen to the HD580s when sleeping

Usbs and 650 are not compatible too

Hey - I'm curious to know what model Onkyo reciever you have. I have the TX-8511 (100 watt), and it matches up well with my HD580s.

It's a TX-DS494. Not a bad little unit at all!

Sat it aside when we moved into a larger house cause it wouldn't drive our new tower speakers.

....it likes the cans though!
