Related to posts on other threads, I recall noting that the Model Two's clock frequency is slightly off 44.1 KHz.

With the Model Two in Master mode, the Weiss AFI1 reads the clock frequency as something like 44.08 KHz (I'm not in the UK right now, but will check the exact freq. when I get back). However, when the Model Two is switched to 48KHz, the AFI1 reads the clock frequency as exactly 48.00 KHz.

Romy, perhaps your Model Two exibits the same behavioiur? If so, could this 0.05% difference account for the anomalies that you're hearing between the Model Two and Lavry? (Of course, this should only be the case when the Model Two is in Master mode.)

To test this, you may want to record and compare a piece at both 44.1 (x1/x2) and 48 (X1/X2). I know the latter will cause you a lot of pain, but keep reminding yourself that it's in the pursuit of knowledge, and you should pull through OK... [do you allow smilies on this site?]

Mani, it is not my case. Lynx card read the external clock with precision of 3 digits after the dot. For 88.2K it reads 88.195 and for 44.1 it reads…. I do not remember now but it very-very close.  I did not try to engage the 48x clock. Well, do play sometimes the 24/96 and 24/48 files but they were not recorded by myself and I never used the 48x for A/D. So what I play only I anyhow mostly use my Lavry Gold.

BTW, of you idea is right then there is a remote possibility that the clock of Lavry Gold is off that this gives some “pitch” difference between the DACs.  There is no easy ways I know to take the Larvy 924 clock out to read it.
