I have to agree with Diki on this one...I found the balance was poor, and since I spent some time on the BK-5 whilst on a road trip a few weeks ago, I know it can sound a whole lot better.
I only tried it in style play mode, and I thought the accompaniments were very nice indeed, with a tad more detail than even the G-70.
The only sounds I found a little disappointing were some of the organ sounds...the rest were very nice.
