Faeio, do you think e9/e17 would be a good match with the he-500's by hifiman??


don't the HE series headphones need some serious power to drive them at low ohm's?

Seems only HE-6 can not be driven by E9, but I guess you can still get satisfy sound level through E9+HE-6, for HE300, 500, depend on what Mike share with us, even E11 is enough .

Yes, that's why I ask, they are very power hungry that's for sure. From what I've read though the e9 should be able to power them..

can anyone tell me the wattage i can get into a 300 ohm headphone with this?

The HE500 is known to be easy to drive for an Ortho, that a good portable amp can drive them well. I have no doubt the E9 will do fine with the HE500.

Hi guys

 

Please excuse me if this is a lo-tech enquiry, but I'm having trouble understanding one aspect of the E7 - E17 option.

 

I use my E7/E9 combo when I'm traveling, and lovely it is too. Going into DT770s at 250ohm, so no drive issues, but if I can make it sound *even better*... :-)

 

Thing is, my mobile music is mostly 256k or 320k mp3s, and a smaller array of lossless albums. Even the lossless ones were recorded from CD at 44.1, so how will the 192 stage of the E17 make any difference? Surely it can't make it sound any better than it originally did? What am I misunderstanding here? And if it did make a difference, would I need to be playing it back from particular sources to reap the benefit?

The E17 is cable of playing back music files up to 24bit 192khz.  It won't(a far as I know) upsample music files from their native sampling rate.  Meaning a 16bit 44.1khz will still be played at this rate on the E17.  The improvement in sound quality will come from the more powerful and robust amp in the E17 and improved usb receiver function among other things.

I'm sure if anything ever "upsampled" at least in the audio world, it would be worth millions. You can't add information to what you don't have (at least not yet that is) :P

Actually, you can.

 

First there is "oversampling", almost every modern DAC does this, if you listen to a NOS (non-oversampling) DAC, you will hear a clear difference, some think it's more analog or vintage sounding, I thought it was errr, not very good.

 

Second there is "upsampling", modern DAC's will either play the signal in native or upsample, ideally they can do both, with a switch, control panel or the software driver.

 

For example the Fostex HP-A3 will upsample all content into 24/96 I think, or on the Musiland Monitor 03 you select your desired sampling rate in driver control panel.

 

Basically it's taking a curve and making it smoother, like in photoshop, it's also adding a massive amount of silence in the upper frequencies, which helps the DAC decode or something like that, the differences are very faint, but it's a still a very desirable feature imho.

crap, I misread the original quote and mixed up bit rate with sample rate. Woops XD

Lol yeah I see, you can't 'upbitrate'.

 

I bet there's .FLAC albums all over the internet that were upconverted from MP3 96 KBPS eek.gif

Making an MP3 into a FLAC doesn't do anything to the bitrate, right? So, the quality level is determined by the bitrate it was originally recorded at....it only gets worse if it's converted to lesser bitrates regardless if it's a FLAC or MP3. Up-converting to a higher bitrate from a lower bitrate is lame since it does not improve the SQ. It can never be better than the original recordings bitrate.

Nope it does bloat the file size but does absolutely nothing to the sound. If you have crap to begin with, you will have crap coming out, there is nothing you can do about that.

What he said ^....that's what I meant too: increasing the bitrate of an existing recording does nothing except increase its file size. It won't make it sound any better.

Mike of Headfonia has some early listening impressions of the E17 here.
