[A6]Audio anomalies on some presets

hi everyone. well, i noticed two things happening on some presets on my A6:

1. low frequency distortion/rumble, especially detectable when playing up 
into 4th and 5th octave. I tried varying the gain structure to rid of it, 
lowering VCO levels going into VCF, lowering VCFs mixer level going to VCA 
etc. but nothing helped. It's not the end of the world, i'm still using A6 
quite a bit, but cant do hi strings sounds without some background to mask 
it.

mp3 examples are here, together with the preset number used:

2. on some sounds using LFO mod of pan there's quite a bit of clicking, 
rendering it unusable:

thru)


My first impulse, after tweaking the parameters etc, was that my A6 is at 
fault, and i run to visit my
friend who has A6 as well - comparison left us with same anomalies!   btw, 
his A6 has a bit brighter sound, and faster envelopes, can this be?!?

a pic from the comparison test: http://www.babic.com/PICs/2ANDY1041-500.jpg

So, now i posted these examples together with preset numbers, in hope to get 
some feedback
from other users and figure out is this common to all Andromedas out there, 
or my friend and i have
got them from the same faulty batch ?!?

i'd appreciate if some of you could spare some time to check how your A6 
behaves with these patches...

thanks
