imho a whatsoever CWA future hardware will feature a different architecture - in the way that more onboard memory is available.
It's the only serious flaw of the cards, but considering the date when the original hardware was designed it just was the appropriate way of doing things.
Those demanding reverbs didn't exist yet and high speed memory was extremely expensive in those years.
Yet one can live quite comfortably with the PCI bottleneck by proper choice of the mobo chipset.
A faster PCI replacement is NO solution at all, since the clock numbers of memory are related the CONTROL lines and NOT the data flow.
That stuff is highly misleading - and it should be known that 'regular' memory architecture is even TOO SLOW for something as stupid as a Pentium CPU...
Imho the cards serve as repair stock, but first of all it's just a reason to trigger sales.
We all know that a Scope pro card is much appreciated for it's DSP power, and more and more devices just ask for it - but a Pulsar One HAS a slower IO system and is likely to disturb at least somewhat.
Under these conditions a trade-in makes sense and is certainly more convenient than sell the stuff via eBay.
my 2 cents, Tom
