HI . I just sold my 3 year old PSR S970 for a very good price as I was not using it but now Im getting the itch and missing my board. Looking at the PA1000 but I once had a PA1x and hated the sounds compared to Yamaha and went straight back to Yamaha. Wondering if I would have the same experience again. The S975 is too small an upgrade to buy new IMO. I always had a gripe with the S970 speakers (Used to have a s900) which had amazing speakers. So now Im thinking Korg PA1000 Or Psr S975 or Wait !!
