DJM-750 - Poor sound with cracking when recording. Sound skips when playing.

Hi,

I've Tried to record my DJ Set within Audacity Using DJM-750 Mixer and when I listen to my recorded Mix, It sounds very bad and having cracking sound within It (I have attached files in mp3 to help resolve this issue.)

What I want to do: Recording my vinyls(phono input) with Audacity by rooting sound to the internal sound cards of the mixer (DJM-750) using an usb cable to my iMac.

See attached JPG to see my software and driver configuration. I've tried severals settings :44k, 48k, 96k with 16/24bits, adding buffer sizes, reinstall my mac, Reinstall the driver, even tried on a PC. No one worked for me.

Also, if I listen to itunes to USB DJM-750 Sound Cards, The sound skips after 1 minutes. I should toggle between internal speakers and DJM-750 Driver to re-enable the sounds to the mixer...

iMac (brand new generation) Configuration: OSX 10.9.1, Processor: 3,1Ghz intel Core i7, Memory: 16 Gb 1600 Mhz DDR3, Fusion Drive 1Tb with 900Mb free space.

Please help me with my new hardware, I'm so disappointed.

Today I split my fusion drive according to this article:

http://www.macworld.com/article/2015664/how-to-split-up-a-fusion-drive.html

Then I reinstalled Mavericks 10.9 on the standard HDD partition.

Result: No more clicks and pops through the 18i20 with some basic tests with Garage Band recording/playback, Youtube playback, and iTunes playback!! (I installed the Focusrite class compliant driver again.)

I will be testing further before purchasing Logic - I have not tried to bump up the sample rate and I'd like to give it more time. So far so good though...
