About to buy Xone DB4 for Traktor/MBP, need to reliability and build quality.

I run Traktor on a MBP on OSX 10.8.4.
Want to buy a Xone DB4 and need to know how reliable its been for you when using the inbuilt sound card, drivers, effects etc.
Some people are reporting serious quality concerns and reliability issues on the official Xone Forum.
Please advice, its a lot of cash!
Thanks

Had mine for 3 years and never had a sound issue using a PC, Mac and CDJ. Not sure if the "Made in China" thing is...a thing. Mine was made in UK :/
I could try to answer other questions if you have any.

I heard they fixed that with a firmware update back in October.
