No just no.  Changing the feedback 10dB when dealing with something that has 100,000x gain... not noticeable if properly level matched with a metre.  Even on something like the GS-X which has an open loop gain of about 30x, changing the feedback isn't noticeable.

Yes solude, it has noticable more dynamic with sacrifice of detail, but definitely for sure, dynamic is increase.
post #3858 of 13877

Interesting.  What are you using to level match?

I've noticed differences with other amps as well-level matched with a $30 spl meter. :p

 

Was it your or Prepo (sorry lol) that used to comment on the large differences with the Soloist on different settings?

Not me.  Never heard the Soloist..biggrin.gif

Not me.  I give out free /facepalm to anyone who uses a stepped attenuator at high gain :P  It's a nuisance at unity gain, never mind 8x.

Can someone explain how internal gain could affect the sound "quality?" It shouldn't, right?
post #3863 of 13877
I cant explain but it definitely affect sound signature for bcl.
Maybe it increases voltage swing to the headphone?
It even change dynamic and signature on my Mustang. I cant believe you guys cant hear the difference.
post #3864 of 13877

I've read that volume is basically voltage gain, so in that respect higher gain = more voltage = more power to the headphones! Of course, only headphones that like a lot of voltage will benefit and the HD800's are defo one of those. 

post #3865 of 13877
More voltage would only benefit if there was insufficient voltage before. But at any given listening volume, the voltage should be the same - the only difference should be the position of the volume knob AFAIK.
post #3866 of 13877

Yeah that makes sense. Higher gain just means less on the volume pot, but the same voltage. Just like a lower gain but higher on the volume pot - same difference. The only benefit here is that some volume pots work better when they are set quite high, so a lower gain is going to be preferred in that case. But that is more for balance I think.

 

 

hmmmm... C'mon Solude we want answers! ;) 

post #3867 of 13877

High gain doesn't change maximum power UNLESS the gain is too low to clip the amp.  Think gas pedal and red line on the RPM gauge.  Once you drop the pedal far enough in neutral to bury the needle, going further doesn't magically add RPM range.  Same with gain and amps.  High gain does raise the noise floor though and makes stepped attenuators are real chore ;)  Particularly no fun on tube amps if they are micro-phonic.

If i set lowest gain, the siund will be very flat, less bass but huge detail. If i set higher gain, more kick on every notes (think piano, drums, human voice rise peak, etc) but less detail and definitely warmer. The more i inceease the gain, the more the same effect increases.

I dont say higher gain increases power, but it change the amp and phone behaviour (hence signature) with slightly higher voltage sent to the phone. I usually set to medium as the low gain is too boring and the highest gain sacrifices too much detail.
post #3870 of 13877
Maybe a dumb question, but where do you go on Sennheiser's website to get the frequency response graph for your pair of HD800s? I've been looking around on there and can't seem to find it.
