The Audio-gd Compass (Was: Designing an alternative to the Zero DAC/amp)

Doorknob move over to Media Monkey and use the steinberg ASIO driver (octachan or something like that). The bass and fullness returns...Foobar and ASIO are goofed up for some reason.

Try it you'll notice an improvement right away. mbd found this out sometime back in this thread.

Peete.

PS The burn in debate...sigh....

I am not saying I don't believe it, I just don't understand how it is possible.



I can't explain it fully but I do acknowledge it. Might have to do with all the transistors used, the sheer part count and the level of overbuild. The NoVer caps take a good while to relax (like Black Gates).

Peete.

Burned in moon for about 10 hrs on bright and love the nice smooth bass on it so far. I leave on vacation for 2 weeks so I put in the earth to burn it in(since I had the compass open to show to my coworkers - all were impressed with the build quality). The Moon had decent (not a lot though) of nice smooth bass. The new earth has almost no bass. I do like the crispness it brings to vocals but so far the bass is almost non-existant with earth. Peete (or others) will the bass get better on the earth with burn-in?


Setup:

X-Fi Titanium using ASIO, bit-matched, to foobar, no DSPs. Well worn HD580s (nearly every day for something like 8 yrs).




Once the Earth is done maturing it actually has more usable bass than the the Moon but it will not have the mid bass hump the Moon module has. The Earth has more bass extension than the Moon.

Try Media Monkey/ASIO rather than Foobar...unless your running an older rev of Foobar your not getting as good a SQ as you should be getting. See my post to doorknob earlier this evening and look for mbd's posts on this subject in this thread. The difference is not subtle at all. I haven't gone back to Foobar even though I like the GUI on foobar much better than MM.

I do believe that has already happened although which Dylan song it was escapes my leaky memory for the moment

MM sounds better than any foobar I tried, but I personally still use the older foobar and the recommended build for the lean sound because my setup has too much bass. If you like music that goes hippity hoppity (I don't know, bill cosby made that phrase up) directsound offers something towards that direction that no asio possibly can

Sorry for OT: Tested quickly Compass with otachan's ASIO-plugin with MediaMonkey and indeed, it sounded a bit better for my ears too. BUT, unless I can't get gapless playback, I'm going to go back to using foobar.

Am I just a noob or is there really no way to to get proper gapless playback with MediaMonkey when using ASIO(4ALL) output? Gapless-mode in ASIO output -settings didn't do anything. Googled a bit and I couldn't find an answer...

I just received my compass but there seems to be something wrong. The right-side volume is at max when the volume knob is all the way down, turning up the volume does nothing to the right-side but increases the left as normal. What could be wrong?

BTW almost blew my eardrum out...I'm really disappointed after waiting all this time and to have this as a problem!!

Edit: I fixed it! the left front (if looking straight on the front of the unit) leg of the alps potentiometer was not soldered!! there was solder there but the leg not connected.

I'm using v0.67, but I go to tools>options>output plug-ins>click Configure highlighting ASIO output>check "gapless mode".

If you can, I'd also follow mbd2884's suggestion to use usb-asio. I can't get it to work though Vista sucks -_-.

edot: forget this post it doesn't make it gapless

i have a noticeable and verry annoying low hum with compass in preamp mode. Has anyone else experienced that?

I can say exactly the same thing happens if I leave my compass on with no music playing through it. The most distinct was the treble disappearing for a while between 250 and 300 hours. I was burning in all 3 HDAMs using my Zero as well, and all 3 had lost treble.

Thanks for the replies guys. Not trying to start a debate as I'm sure there is some science behind it... too much consensus to be a group psychoacoustic phenomenon. I'm interested to see if I hear what you guys are describing.

You need to load the system with a headphone or speakers and be pumping either music or Pink noise! I created a special WAV file for 9 min of pink noise and 1 min rest then repeat 6 times for a one hour file. Then Media monkey will keep track of how many times this plays so I know my total burn in except time spent listening.

There was a little tutorial on this thread, post # 4036 by TinselJim, I used which was extremely helpful to create the file. Thanks Jim!

The pause is to give the drivers time to cool, there have been some people who have burnt out headphones doing there burn in.

Hope this helps.

Surprisingly fast shipping IMO for international (maybe it's the norm, but I rarely order from overseas), when did you place the order?
