The HE-400 can be very good with Jazz depending on the type of jazz and such. Gives it a nice energy, though without certain instruments being too fatigueing (saxophone in Miles Davis 'Kind of Blue' comes to mind)

If you are talking about EQ'ing it ain't gonna happen, haven't used an EQ since I was a in high school (1986), so I may be moving through the HE-400 pretty quickly.

Why won't you touch an EQ? You don't listen through the computer or something? It isn't a very drastic EQ we are talking about here, and I doubt it will degrade the audio in any way.

I'm using this features on Xonar ST and it is a big difference, the music opens up more, soundstage is glorious, the mids change  for the better, without these effects mids seem muffled.

Before these orthos, those effects did nothing good to dynamic headphones, so I didn't use them, but now I cant do without Dolby DSP.

I'm using vintage amp and/or Xonar ST with LME49990 and I have no problem with sibilance.

Dolby headphones DSP muffles everything for me, make it seem very muted. That is with foobar and stereo recordings. To me, that sounds very bad. On the other hand you can do stuff to improve on that. I have a custom channel mixer DSP, that converts stereo to multi-channel, and then I apply dolby. That sounds quite decent, actually, but still lacks some clarity.

What is ProLogic?

Dolby Pro-Logic IIx is a 7.1 surround upmixing technology and is widely used in
home theater systems, TVs, game consoles, and car audio systems. It can expand
stereo audio, such as MP3, CD, and TV programs into immersive 5.1 or

7.1-channel surround

No idea why they say they can run straight off your source with no dedicated amping.

Just would not get anywhere near the full potential out of them and the casual tester may just think they are so-so without extra amping.

Im not sure i could agree with this (the table).

While the HE-400 run great off my Schiit Asgard (max 1 W, but im quite sure it has some headroom as it can deliver 1 W even if you get some strong dynamic swing), my Fiio E17 dosent really run that well, even when USB plugged into the PC (note that the E17 I have runs a lot louder as DAC+AMP when USB plugged  rather than my Mp3+E17 as amp only).

 

Id say if id have to give the HE-400 a power requirement id rate them between 650mW and 900mW.

The HE-500 id say 1.5 to 1.8W

Note that the Fiio E17 actually dosent deliver too much power to drive orthos, even if its ok in volume. (talking about the HE-400 here)

 

Can Valhalla drive my orthodynamic headphones?
Being polite: not a chance. Although Valhalla can deliver large voltages into high-impedance headphones, it cannot supply the current needed for low-efficiency, low-impedance orthodynamic headphones. If you have Audeze or HiFiMan headphones, look at Lyr. LCD-2s, HE-400s, and HE-500s are also efficient enough to be used with Asgard, if you’d like an all-solid-state option.

 

The valhalla outputs around 100 mW at 50 Ohm, and the Fiio around 160 i belive.

Than explains. Don't know how good the upmixing is, but with the dsp's I use it sound quite decent, though I prefer listening without in the end.

Good to know the minimum requirements you think for 400s.I'll bear it in mind when buying a smaller second amp. I think that table was actually provided by Hifiman during an interview about the line.

Unless you're listening through a cd player or something other than your computer, you have no reason not to EQ.

Do you think that the EQ on your computer has no effect on the sound quality?

I think so.

A simple treble rolloff?  Little to none.

 

What's more, is if one were to define distortion as anything deviating from the norm, then the treble spike of the HE-400 is a distortion and a treble rolloff helps mitigate that distortion.

I never use EQ's, they are another level of "stuff" between the recording and your ear.  What do you use?

You don't want to know what sound engineers do in the recording process then... We are pretty much only talking -2dB at 8 kHz and -5dB at 16 kHz or something like that, so you can use pretty much any EQ. Personally, I like to use a parametric EQ.

I'm done talking with you, you're melting my brain.

Wow, I am trying to have a conversation and ask you what you use and you are kind of being a jerk.  Did I immediately jump to "you have no idea what you are doing and no REAL audiophiles use EQ's? No I didn't...I am asking you a simple question.
