HD650 Redux
« on: August 24, 2012, 08:08:32 AM »
Listening to HD650 from the HeadRoom Chest. These are the ones that Anax said sounded veiled. And they do, which is wierd. I did not think Anetode's (nor MacKat's) HD650s sounded this way, and I know my rig has not changed that much since then. They sound a little bit better on the Dynahi than the BA, but really not by much.

I'll measure these and see what happens. The bassy is muddy on these. HD will be interesting.

Do they have the silver screen or the black screen?

I made sure mine is the silver screen version before I purchased them second hand, and they're just slow, not veiled, only the black drivers ones are considered veiled, I think.

Re: HD650 Redux Frequency Response and CSD Waterfall Plot

Wow. I never expected this. They measure quite differently from Anetode's pair. BTW - the pads are deformed differently - probably accounts for the frequency response differences in the treble.

That's quite flat. Maybe you are lucky...

Interesting. I owned the silver HD650 and always found descriptions of veil perplexing. Unit variation or is there really something to this black vs silver screen urban myth?

@Uzi's 650 even had a <very> slight "bit o' air" over Mackat's pair (I thought). 


Two pairs over 2 yrs that I have heard (had 2 weeks with both 600/650 simultaneously plugged into DAC1 for A/B) seemed veiled. 

But that was during my "Cretaceous Grado" phase... :)p14

Re: HD650 Redux - Distortion Measurements
« Reply #8 on: August 24, 2012, 08:48:37 AM »
For reference, Anetode's pair:  http://www.changstar.com/index.php/topic,40.msg195.html#msg195

They sound better now that I've acclimated to their sound and cranked them up a little bit. Seems like there is a 3-4k emphasis (subjectively). Bass is still slow and it's veiled compared to the 'stats and HD800. I'll post the distortion measurements in a bit. (POSTED)


HD measurements with headphones at SPL/A 90db white noise.

Looks like slightly high D3 (3rd order) in the bass to 200Hz. I don't like to see 3rd order over 0.1%
D2 is high below 40Hz. I like to see 2nd order < 1%

Compare HD to others (HD800, MS1, HE400). Bass distortion characteristics are similar to Grado, but I think Grado's elevated treble masks the bass distortion. EDIT: The rolled off bass of the Grado makes bass distortion less evident.
