The "big oscillator" unit should be here any day now.
In anticipation of the upcoming test/comparison between the two, I would like to better understand a few things:
1. My unit has a big MEC oscillator and a small one, unlike other people who got 2 small ones. Does it mean that one oscillator handles a frequency and its multiples, and if so is there a "easy" way to know which one?
2. How do the two work together? Since there is a large one in the mix, would that contribute to an improvement over just having 2 small ones (ASSUMING that the small ones are inferior)?
3. I ran many tests with 44.1 original and upsampled to 48khz, as well as original 88 and 96khz. ALWAYS the original sounded a bit better than the upsampled version. How can this be interpreted with respect to having one big and one small osicllator?? (All upsampling was done with foobar's sox. Also my unit sounds better than straight out of the pc card (bit perfect realtek)).
4. I think that although fairly modest, my system is transparent enough to reveal a relevant sonic difference between the two units.
5. Here is a word by word copy of the email I got from Marco:
Hello Danny,
for what relates to performance, the only difference between small and large oscillators is... the size. The supplier who gave us the small oscillators during a period in which the larger ones were not available, gave us warranties about performance level of the small units, Particularly, low frequency phase noise figure is even better than the large units...

Hi,
I have a hiface that I purchased about 3-4 months ago. I am sure you are aware of the confusion over how some of the hiface units have two bigger MEC clocks versus 2 smaller ones.
My unit happens to have one big clock (located near the BNC connector) and one small one. A lot of people on the forums report considerable sound quality differences between the two, as the general idea is that the smaller clocks used are of lower quality.
Can you please tell what differences (if any) are between the bigger and smaller clocks M2Tech used in some of their hiFace units?
Regards,
Danny
In light of my tests and the fact that I can listen without any fatigue, I kind of tend to believe it. BUT, the moment of truth is right around the corner. (I just wish the Post Office would get off their butts and deliver the testing unit, it's been sitting either in their warehouse or customs since the 17th, according to the tracking site...
We shall see!!
