The HeadAmp GS-X and GS-X MK2 Thread - Page 8

4pin XLR but... why?  IEM are really really easy to drive so single ended would be more than fine.

How about another one of those status updates biggrin.gif

Still in the estimated 2 week window for matching so guessing no change other than he's really tired of matching parts :p

You double the noise floor driving IEMs balanced, for that reason alone i would recommend the 1/4" jack

Does the noise floor double for all headphones in balanced mode?

post #111 of 3941

No just IEMs because they are made of unicorn dust... no wait ;)  Key is noise floor not THD%.

Why does the noise floor double with IEMs but not with other headphones?

post #113 of 3941

It doubles with everything, IEMs, headphones, speakers, everything.

Sorry if I'm a little dense on this matter, but it seems to me that doubling the noise floor is a bad thing. Do the other advantages of balanced operation outweigh the effects of doubling the noise floor? Thanks for the clarification. smile.gif

Depends on whether there is a floor to raise to begin with.  The Dynalo, the circuit HeadAmp home amps is based on, are super clean.  So doubling nothing is still nothing.  Balancing a noisy amp... bad.

the noise floor is so low, you'd never know the difference with anything except maybe certain IEMs you might get into a very, very minor hiss.  Also, the gain is doubled, and IEMs already have issues with amps having too much gain.  So the 1x low gain setting becomes a 2x gain, requiring the volume control to be set lower.  there really aren't any advantages to driving IEMs balanced.

hope i didn't start anything.....i asked only because i read gsx(previous version) sound better with the xlr output(comparing to the 1/4 output).  regular iem cable mostly are too short so if i ever going to use an iem with gsx i might need to get a new iem cable.  i thought about maybe ordering one longer cable.  i guess it's not necessary, i have an extension cord and i don't really use iem a lot at home.

Dynalo low is very clean, but as Justin indicated, you can hear noise with some sensitive  IEMs. I can hear slight noise from both a Gilmore Lite and the GS-1 using Westone ES5. I am expecting that this slight noise will go away with the GS-X balanced, thought I wouldn't bother with the GS-X if it was just to remove that little bit of noise.

The gilmore lite has a gain of 6x, so there would be a slightly audible hiss with the es5. You cant hear anything on the low gain setting of the gs-x which is a 1x gain

I'll take a set of upgrade modules as well when they are available. Thanks.
