I had the original Micro Clock for a year or so...
Then upgraded to the Micro Clock II when it came out.
Man.....whew.... what a weapon.
Anyone that reckons that clocking makes no difference needs a new set of ears.
I always had trouble with harshness in the hi mids and woolly bottom end when I clocked with RME converters.
The BLA MCII - wow - my mastering engineer heard the difference and asked me what I had changed as it improved my sound A LOT.
Thanks BLA.
OH BTW - I have just bought a HD4 system with 2 x Lynx Aurora 16's....
I will be doing some tests with and without the Micro Clock II and fully expect it will end up on clock duties permanently for my HD rig.
