Thanks

If you're going to get a cost-no-object DAC why not have the same attitude concerning your transport?
Personally, I would look into the RME Hammerfall PCI cards.

The product blurb on the web site says:

it's the first converter to feature our proprietary new MFAST™ (Meitner Frequency Acquisition System) technology.

MFAST™ vs. conventional PLLs

Most converters utilize PLL (Phase Locked Loop) circuits. MFAST™ has two distinct advantages. It's a high-speed asynchronous system that locks almost instantaneously to any data stream. Moreover, unlike PLLs which merely attenuate jitter, MFAST™ strips jitter out of the audio stream completely

Hmm, Anybody know anything more about this approach? Enquiring minds want to know.
same here.


Anybody care to enlighten us?

I may only guess that they use something like caching a data stream in the RAM and then outputting it with the correct timing. TC Electronics BMC-1 and Genesis Digital Lens AFAIK use this kind of approach to eliminate jitter.

well, a phase lock loop is basically a electronic circuit that phase locks onto your input signal. i'm guessing that digital signal is probably sent as small wave packets in which the dac then fourier transforms to get useful information. The phase lock just keeps the signal from jumping around like when you have a bad trigger on an oscilliscope; hence creating "jitter". i'm sure the dac2 has an internal clock in which it synchornizes the phase lock to. i think the "clock input" thing on the dac2 is so that you have the option to use an external trigger instead.

I hate it too. It just nearly doubles the cost.

Interesting match, try it! The equation's incomplete without the amp and phones considered of course.

My kind of expensive dac makes my very cheap cdp sound awesome, btw.
Exactly what I had in mind, but now I have to buy a pre-amp also.

I think at this level,,,,their is no "big jump up".

The only big jump up..is the price,,,, Don't get me wrong, I am making the big jump tomorrow,,Scares me how much money I am going to spend on a CDP...

Welcome trcnet, and nice review..
