Ok thanks guys.   One thing I'm wondering - at what point (using the volume dial with the preamp out) will the preamp out start to be 'hotter' than the DAC out? Or is it something like 1% of the total output?

Hi,   The situation-   I use Foobar2000, run via USB into a Audio-GD Compass.   I plan to add a Blue Sky 2.1 active monitoring speaker system.   Two Q's -   1. The Compass' DAC output is RCA. Will RCA - XLR cables connected to the monitors work ok? 2. There is no universal...

Fostex T50RPs looking good so far....

Hi guys, so my PRO900s just died... (see other thread)   Got some KSC75s for now, but looking to get some main cans soon as I won't be able to use any speakers in my new living space.   Using - foobar2000 to an Audio-gd Compass (using built in amp). Listen mainly to electronic music...

So, as above!   Right PRO900 driver has died (definitely the driver, not the cables etc).   It would be a shame to let the gorgeous casing go to waste, but I was never THAT impressed with the pro900s to be honest. Required too much EQ to bring the resonance down (for my taste). I have no...

Quote: EQ out the sibilance + turn up the volume, add a Sonic Maximizer in there, and add a room simulator like TB_Isone.   Then try :P

Quote: Definitely would work. I'd leave the bass alone, since with those cans that's probably the coloring you like. Just tweak the 1KHz+ range

Quote: It's more complicated than that...    

Quote:   Yeah, some people seem fine with the brightness, but the sibilance really gets to me. PM me if you want the .fxb EQ preset for the pro900s.   Quote: haha great. Any improvement? :D  

Quote: How so? Just double-click the point, choose the freq, gain, and width.

Latest attempt at taming the PRO900's highs....

Check this out-   PRO 900s with a flat-ish high end!     I know what you're thinking... no high-end, no fun? I say, no sibilance, LOTS MORE FUN!   I've largely left the lively bass alone, but the highs are now silky smooth...lovely.    

Quote: Try an all pass filter to bring the overall level below 0db.

Quote:   If you're using foobar, download the VST wrapper and try a decent parametric EQ, like Electi-Q.    

Yeah , the peak at 6K gets to you if you're treble-sensitive.   See here-   http://www.head-fi.org/forum/thread/564465/misconception-of-neutral-accurate/60#post_7646530

Just like to update this thread-   In the end, settled with an AudioGD Compass DAC/Amp and a pair of ULTRASONE Pro900s. Using a parametric eq to eliminate the sibilance, and TB_Isone to expand the soundstage.   Highly recommend this setup!!!   Thanks for the help. :)   (btw, My...

Just got my AudioGD Compass for these babies.... oh my. Amping difference is fantastic. Richer, (even) fuller bass, smoother.

Anyone else finding that this works wayyyy better with neutral/EQ'd-to-neutral headphones?

Quote: Either use the preamp setting or an all-pass filter to make sure the highest output from the equalizer is <0db

Quote: What??? That would EXAGGERATE the pro900 signature!!! Madman!  

ok guys.....  HOW do you listen to these without EQ??? Honestly, the sibilance is brutal. Either my ears/brain are too sensitive, or my amp is useless (got a Compass on the way).   Here's my setup so far-     Gotta say though, the bass IMPACT (especially with the cheeky Sonic...

I don't understand.... Why don't you just EQ out the sibilant peaks with a parametric EQ?

Quote: If you're looking for big bass from the M50, especially unamped, then you'll be disappointed. It has good low extension however.   The high-end of those two couldn't be much more different. The M50's high end is quite abrasive and unforgiving, whereas the k81's is soft and gooey.
