inside a System 700

Update via ST: "Most of ppl don't know,but there are 2 different system 700's released each with different electronics.

They both sound differend ,one is more punchy and has better filters as the other (thats why there are different
opignions between those that own or did try a 700 (like stated in the Peter Forest AZ books)

Differences are in following modulles: ADSR,RING,VCA And FILTERS

VCA old systems are noisy low dynamic CA3080 based
The later uses the same OTA's IC's as in the 100M

RING,The old system uses a MC1496 IC's design ,not the case in the
later one models that use a different design.

ADSR old poor slow attack in old systems
later system uses same 100M design

FILTERS,in the old systems poor ceramic caps are used al over in both filters
Later systems they upgraded with hi Q styrene caps everywhere
the resuslt is the later system filters sound more accurate and give in combination
with the better VCA's and ADSR's a more punchy sound

I would describe the old system ,more organic sounding and the later
dynamic and punchy

If i have to choose ill take for sure the later systems,they realy sound much better in the end (more bass to)

How u can see u have an old or new 700? ->

Pull out the modulles and check lol (check some pics in attach),no in fact there is also a physical difference from the outside but cannot be seen well on pictures:

Old systems have plain white graphics,while the later systems there is a 'siver-ish' glow in the color of the graphics."
