The Yamaha AN1x Synthesizer mailing list

Please forgive me if this topic has been discussed previously but I 
scanned the archives and found few references.

I was reading about the PLG150-AN at XG Factory and noticed the 
following statement:

"There was always something about the Prophet 5 that made it sound 
wonderful. Maybe it was the filters, maybe the oscillators, and maybe 
the overall design. Whatever it was, it inspired Yamaha to develop 
the PLG150ANX, based around our acclaimed AN1x synth technology, but 
revoiced and re-tweaked to give you as close as we can get to the 
original sound of what many people call the best analogue synth ever 
made."

Can someone explain the difference between these two products in 
terms of overall sound quality?  Does the PLG150-AN really sound all 
that different than the AN1x?

Thanks,
