use a safety pin, push the reset button, sometimes it gets "stuck" in dead mode

A few newbish questions incoming:

 

From what i've read about amps on this site, some have a "balanced" interface between components and some have "single ended". Which is the E17? 

 

I've also noticed that cables in the same manner can be terminated for Balanced/SE? Why do cables need to match the internals of amps?

 

Thanks for your time! beyersmile.png

The topic of balanced vs. SE goes much further than what I can explain, but in short, E17 is SE. Most headphones are designed for SE as well.

In SE, both the right and the left channel are referenced to the ground channel (only 3 wire needed). In balanced, the left and right are converted to Left+, Left-, Right+, and Right-. The original goal of balanced audio is for noise rejection during long distance cable transmission, but people find balanced audio sounds good in their opinion, as it doubles the slew rate. Since balanced audio must carries 4 signal, typical headphone (which usually only has 3 wires inside) need to be recable, or at least separate the ground wire to two so you get 4 wires for 4 signal.

Thanks ClieOS. I assume that most default cables that come with headphones are SE then? Mostly i was confused about whether or not i have to order a new headphone cable (HE-400, once i get them ordered).

HE-400 comes in SE cable, you don't need to change it.

Perfect, thanks.

Any TRS connector is single ended, ( Tip - Ring - Sleeve ) Where the Sleeve is the ground and tip / ring are the +V for the left and right channels, so thats your 3.5mm or 6.35mm jacks sorted.

 

When you are going Balanced you will most likely be using an XLR or mini XLR connector to give you 4 pins to connect to the amplifier , so re-terminating a cable you have , or getting a 2nd cable with XLR connectors is your options.

Just to add that it is mot necessary an XLR / mini-XLR termination with HifiMan's headphone. Their own balanced cable are terminated in TRRS, which is their choice for portable use. I think there is a TRRS to XLR adapter as well. Unfortunately every manufacturer on balanced portable gear all have different termination of their own. The situation is kind of messy and it all depends on what amp you are using.

TRRS for balanced ? What would be the point, I wasnt aware of any desktop amplifiers that supported such a format , seems a bit pants, it is a huge mess, the closest we have to a standard is XLR / mini ... oh well , ya learn something new every day.

It isn't for desktop, but for their HM801's balanced amp module. XLR is too big for portable use, that's why iBasso and RSA all adopt their own version of balanced plug.

Hey all,

 

I'm getting conflicting reports from people as to whether the E17 EQ functions work when you use an L7 line-out dock.  Can anyone positively confirm or deny this who has and uses an L7 with their E17?

 

Secondly,  the biggest plus for me about the E17 is the clean bass boost I can get with EQ.  I find it much cleaner and with far less distortion than EQ in foobar.  Maybe I'm not doing EQ right, but that's been my experience.  I can also get to where I want the sound much faster with E17, and I don't spend all my time tweaking and not listening.  

 

That said,  I've been wanting to acquire a desktop DAC since I always listen to my rig at home.  Is there a desktop DAC that offers this same kind of functionality, or would work better with foobar EQ if I wanted to tweak like I do with my E17?  Thanks in advance,

What you are doing when you "EQ" and the programs and how you are using it is probably the incorrect one.

 

Most audiophile DAC's don't offer any EQ. And those that do work like the E17. Not with a specific program.

Probably not the correct one, huh?  Guess I fail the audiophile game.

Real EQ is actually very hard. There are some guides online but the problem is

 

They are generic, and are meant to teach you programs and how to use it and then you go off on your path

 

They may be very very custom made and tuned for each person through very in depth tutorial or just very general. 

 

The programs listed are generally very ..not publicized and links and versions and programs may not be availble anymore or with bad support and or different versions used.

 

RPGWizard has a guide and Joe Bloggs has a guide. RPG wizards is easier to follow and more general teaching you and then you do it and try by yourself. While Joe's is a custom approach..only problem? His guide sucks. I love you Joe and I know you are reading this but that is the only thing to say. Why? He wrote it in the most unorganized way ever...it is literally everywhere with links linking elsewhere with no contiuation and ..everything.

 

I am getting custom help step by step right now from him on a REAL EQ.

 

The regular EQ is easy. Get a good program that has the features and abilities to do what you want(some don't) and then ...raise or lower some FQ and what not and see if you like it...but those generally may not work too well for some.
