For the eq thingie: one of the others can reply that better..

Yep, laptop being fed by a 2 tb media drive.

 

Re: the DAC...it was posted elsewhere on the forum to specifically go into the DAC properties and set to 24/44,100 even though the files were at 16/44,100 which allowed lowering of the master windows volume without discarding any information as the other 8 bits were empty.  Sorry I can't elaborate, but I don't yet understand all the science.

 

If I turn my master volume to full, even the lowest volume on the amp is too loud.  The new EQ settings helped with this a bit, but not enough to put the system volume to 100%, so I have to attenuate somewhere prior to the amp.

If you don't like using the windows volume control you could use WASAPI plugin which bypasses the windows volume control. Then you control the volume using the slider in Foobar.

about the volume..if the volume is to loud (thats also because of the peaky treble that the he400 sounds unbearable loud very fast) try to go down with the volume on pc until u can use the volume on the amp a bit normally..but still..the shiit u use is not a very powerful amp..i find it odd that it is not usable with pc volume on max.. But i am guessing the he400 is very efficient to be driven then..

And nicholars is right..wasapi bypasses the internal volume..but am guessing that will be to loud also..as my pc sounds the loudest (but best!) when using wasapi..but try it out urself..

About dac...i was talking in general..but as I never used that dac, i see i am not right person to give u specific advice on that one... Am sure others can help u with that.. wink.gif

Hi,

 

Am using WASAPI on exclusive but still doesn't bypass windows audio control...at least not on my system.  Additionally I do not have a problem using windows audio control, just looking to make sure I am not hampering sound quality by doing so.  

 

I will try to find the thread on this and post it.

Nah I doubt it.... Just set the volume to 30% or something... I do not think it is really an issue with windows 7 / 8 ....

In case anybody is curious about this, the discussion can be found here starting about half way down.

Sorry for hijacking the thread.  I think you are right in that it does not make a difference on Windows 7, so will leave it as is....sounds good!

The sound card in your laptop will be completely bypassed by the modi USB. The windows system volume will be controlling the modi USB level directly.

Set it to 100% (the windows system volume in the system tray for the modi USB output).

 

Use replay gain to set your volume to be consistent through out your music collection so you don't have to be fiddling with the volume all the time.

If you haven't already done this, you must do it, it will prevent having to adjust the volume after every song and throwing shoes at it.

 

Set your software player for music to 100%.

The only place you will control your volume from is your software player(s).

You can leave this at 100% always since you will use replay gain so that all songs will have the same loudness.

Next, set the physical volume on your magni to about your normal listening volume and leave it there always (* see below).

This is what I do and it works for me.

 

* Instead of setting the magni volume to your normal listening volume, you can set it to say 150% normal listening volume, to give you some leeway for when you listen to youtube etc. that don't have replay gain applied and which may require a higher volume. You then use the volume control in the software player (youtube in the case) to control the volume as required. Your software player for music won't be at 100% anymore in this case too, set to it to match your normal listening volume and leave it there always.

 

Some other points...

You can set the modi to 24bit, and according to that thread you linked, it will then allow you to reduce the volume (anywhere in software) with no data loss.

There is a lot of ifs and buts in that thread so I am not sure it's 100% accurate but it can't hurt to do that (but it might cause drop outs if your pc is slow).

I don't notice any difference if its 16 or 24 bit.

 

With regards to the EQ volume, its not really there to be used as a traditional volume.

Your EQ setting (nicholars file) is reducing all the frequencies (everything is below the 0dB y-axis), so you should leave the volume at 0dB always.

If you had frequencies being boosted in the EQ, say the bass was boosted by +4dB, you would then reduce the volume by a matching -4dB to keep the overall frequencies always at or below 0dB. This is to prevent your amplifier from clipping and causing distortion.

A new electronic Linkin Park album? I'm all over that!

 

@nicholars, that's an interesting EQ curve you've got there. I'll give it a try the next time I put on my HE-400 which unfortunately won't be tonight. But just to give some thoughts on it based on what it looks like, it seems a little too excessive for my tastes in the bass region and even the treble dip at 12Khz. A lot of people already consider the HE-400's bass forward, so having that big a gain would cause my head to rumble lol. Great for the wow factor, but in the long run would get tiring. Also from my experience I find most sibilants to be in the 8-9 Khz region where you haven't lowered much. Maybe this is why you say you still experience some sibilants? 

 

Not too long ago there was a discussion here about purists vs non-purists, or something along those lines. I'd side myself on the purist side which explains why imo and for me most importantly your eq is a little excessive, even though I have some EQ of my own going on. Mine is just a pure treble fix, no other region is touched. If I change the entire frequency spectrum, then it won't even feel like im listening to an HE-400. I don't want to stray too far off the sound Hifiman intended. Keep in mind I'm not criticizing your EQ nicholars, just pointing out how we have different tastes and how it suits some more than others. I admire your dedication though to get the best sound for your tastes.

 

And while we're on the subject, I may as well post my latest effort on my config. I've changed it a little since my last revision. I took a huge scoop out of the treble. I really don't know what Hifiman was thinking putting that huge spike in there. This works great for me...

Hi there

Has anyone tried he400 on Rsa Predator? how is listening sound level? I consider using it as a dac-amp directly connected to a MacBook.

I think you are right about not doing too much EQ because it starts to sound weird if you do too much... But with my EQ I posted you are missing the point, It is a template.... I went through all the frequencies using Sinegen and made that EQ.... I thought it would be a good template to give to people because as long as you only change the gain on the points (do not move the points left / right).. you can change it to any sound you want..... You could make it flat if you want and make the dips smaller... as long as you keep the same shape it will always sound better because it is lowering the treble peaks and the glare only......

 

It took me quite a lot of fiddling about with it to get it the right shape and so that it can easily be adjusted.... I use a similar one to that but with less EQ on the midrange for harsh or bad recordings because that is very good for smoothing out really bad quality songs.  For better quality I use one which has more treble and I have one with less bass for some genres. Try the EQ but move the points up and down only to make it how you want... I guarantee it will sound better, unless your HE400 sounds different to mine. Alternatively you could measure your own headphones with Sinegen. For example I just did this one in about 1 minute by keeping the same shape but changing only the gain on the points...

 

Your EQ looks alright but you can leave that lump around 8-9khz area higher because there is no treble peak there... whereas there are 2 obvious peaks at about 7.5khz and 12.5khz as you can see there. Also a little dip in the midrange like on that one makes them sound better because of the ringing.

 

 

 

The good thing about the EQ is that all the points are in the right place so that you can make it sound however you want by just keeping the same shape but changing the gain setting on the points only... Both of those example took me less than one minute.... Whereas mapping all the frequencies using Sinegen was a pain in the ****!

Here is another one for you, flat but with treble reduction...  It has almost as much detail as no EQ setting but the pain inducing "tizz" from the treble and the sibilance is almost gone....

I am bored of EQ'ing now so that is the last one :D

Thanks a lot, I'll test out those EQs and get back to you

Nicholars -

 

I didn't DL your EQ file because I use Easy-Q, and don't want to switch to Electri-Q. I have been using about the same EQ curve for months already, but 'copied' your slopes as much as I could. Some day I'll invest in an SPL meter / Mic / test tones and sweeps so I can get more precise, but anyway.

 

Some comments.

 

Your bass curve is basically a shelf curve - you can cut down on the number of points if you just pick 'low shelving' and play with that. I personally use a 'peak' style curve @45hz. 2.5db boost, about about 1.75 Q. Bass is not really audible to my ears starting at around 30hz or so (certainly not when using headphones), so boosting a lot in that region is really just stressing out drivers and possibly risking damage to your ears. That which you can't hear still contributes to SPL.

 

Otherwise I think the tweaks work great. I personally don't use so drastic a spread. I am +- about 5 dB from peak to trough. I may change that to about 6dB, but your peaks are pretty aggressive!

Your combo of Schitt Modi to Schiit Magni to HE-400s after leaving the computer is wonderful if your stationary.  However, if you're on the go and need a portable amp to use with the 400's.  Well, I have tried several and surprise, the C&C BH2 seems to do the job......Wonder if anyone else has experienced this little hard working amp?
