Also keep in mind the EQ curve I showed you was for a GS-1 amp fed by a Northstar dac.  Your's might be slightly different so adjust to taste.  You'll find out very quickly that you know what sounds good to you.  Just remember to make small changes.

 

If you really want to experiment, there are EQs that you can download here: http://isohunt.com/torrent_details/91836085/?tab=summary

 

I play with these all the time.  Sometimes it's interesting to combine things like a 10 band simple high lift with a 30 band gentle low cut.  It's like making your own Fletcher Munson curve for the 650s.....

 

Season to taste or turn the EQ off.  It's all fun.

Hi,

 

Just ordered a brand new HD 650 today! I also bought a dac/amp for them, the Audio-GD NFB-12.

 

This will be my first entry into high end (from my perspective anyway) headphones. My best headphones up to this point was a HD 280 Pro. Hopefully these will last me a while and make for some nice listening :)

Thanks USG,

 

I've been using some ****ty presets I found, but these appear more technical as well as with a better naming scheme. The only problem is the torrent doesn't work.... can u seed it :)

 

Oh and congrats again ac500 wink_face.gif

Then I suggest you stop coming here.  tongue.gif

Just want to share the love.



Ah, yes, other way around to me. I got the PXC450s as travel headphones, loved them, dug out some old HD435manhattan, realised the HD435 blew away the PXC450, saw some HD650 for £199 delivered (new, boxed, etc), and pulled the trigger on an impulse. Fantastic phones.

The rest of my setup may be lacking - Laptop H/P out into a Bravo Audio V3 amp. What makes me think the laptop H/P out may be a weak link in this setup?....

Everyone is using "EQ" to shape the sound of their phones - when they mix and match sources, amps, tubes, op amps, cables, etc. 

 

Just not everyone uses frequency attenuation in the form of an Equalizer. 
 

 

 

hah, yes. I bought my wife that. Keeps her busy when I'm listening to music. Very good wink.gif

I was just talking to a friend of mine this evening about a good value headphone set-up and thought that HD650s and an NFB-12 would be a good choice for him. That's a very spooky coincidence, although I do have the 650s myself.

 

Please post your impressions. I'm also interested in some of the Audio-Gd products for my own use.

That's a really stupid, silly price... do they have any more?

 

A pal of mine is interested in a pair and at £199 I'll lend him the money... the best price I found when I bought mine was £260 frown.gif

I'll be sure to post my impressions as soon as they arrive :). They should come in some time next week I think.

post #3700 of 36831

Not at the moment. It was from this eBay seller. S/He had several HD650s for £199 when I bought mine

Well, I didn't, but you worried me, so I just did, and sort of found the same as you - 

Using Foobar and the 18 band equaliser (File | preferences | playback | DSP Manager | Equaliser) I turned everything down to -20dB, then moved the 14 and 20KHz up and down.

On my 44KHz recordings (i.e. almost everything I have, although I only tried 8-9 tracks using a mix of CD, FLAC and MP3) there is plenty of response at 14KHz, but nothing at 20KHz.

On my 48KHz recordings (which happen to be DTS, too), there is also response at 20KHz (both with and without the Dolby Headphone DSP)

 

The up-sides to this are I know my headphones work and won't worry any more.

The big downside is now that I know I can hear the benefits of 48KHz recordings I will have to spend far too much money and time replacing a 20 year collection of CD's.

 

[ I then tried repeating it with the 31 band "Graphic Equaliser" that was an optional component install. It has bands at 12.5K, 16K and 20K. There is response at 16K on both 44K and 48K recordings, but none at 20K on either recording. My knee-jerk reaction was to say the second equaliser is broken. On second thoughts, the first equaliser labelled 20K probably lifts everything above 17K, and the second one everything above 18K, and then maybe it's my laptop HP-out that has a cut off somewhere 17-18K, or my Bravo amp, or my HD650's, or my ears. Yes, I know I shouldn't be using the headphone-out on my laptop. I'm working on it, alright ! ]

Just gave myself a hearing test here http://www.audiocheck.net/audiotests_frequencycheckhigh.php

I can hear the 44KHz file at about 17.5K, and the 48KHz file at 18.5K. Assuming the files are correct, there's something wrong with my laptop. That I start to hear somewhere in that range also suggests why I can hear one 20KHz equaliser but not the other. Still doesn't clarify whether it is my ears, laptop, amp, cables or cans that roll off the highest frequencies though. I'll assume it's my ears that lose the highest frequencies, the laptop loses quality, and the cables, amp, and cans are not the limiting parts.

 

As an aside, FooBar and Chrome alias the 48K file yet WMP plays it fine (on my setup). Any pointers to fix Foobar would be appreciated.

OK, not everything is as it seems.

Re-encoding the .wav tone tests with CDex, either file will alias if converted to 48KHz, and neither at 44KHz.

On top of that, I am using Waveform SeekBar, which shows that MP3 encoding (Lame, 320kbps, max everything) is filtering away everything above 20KHz anyway. The MP3 file does not contain the 20K-22KHz tones that are in the .wav file.

On top of that, I have played with the SOX resampler plugin in Foobar. Any setting of 44/48/176 plays aliasing 48K files without problems, and any setting of 48/96/192 adds problems to otherwise fine 44KHz files.

A shortcoming of my laptop soundcard I assume.

So, now going back to my 48K music and the equaliser tests. With SOX running, the 20KHz equaliser does nothing (that I can hear), so maybe the earlier test was just amplifying aliasing. Oops. I don't need to upgrade my CD collection! Hurrah! But I might need to re-encode it. Darn.

Suppose I ought to get a Yulong D100 DAC or something instead of using a laptop. But I still don't know if my laptop if filtering off at 18K or if its my ears or cans, or even how much of my music is filtered into the audible domain.

====================

For foobar make sure you are using wasapi, otherwise you may get resampling from windows for everything you play. For WMP, I'm still not sure if it is possible to get bit-perfect, but using wasapi and making sure the volume control is set to 100% is a start.

I bought a pair from amazon yesterday, I can't wait for them to come in tomorrow.
