I’m looking for an external amp for my Kawai ES920 and was hoping to get some good suggestions from the ES920 crowd. It needs to be light weight and I’d prefer if the amp would project an all around sound rather than straight directional. Not doing rock concerts here, just jazz, country club and restaurant playing. Mainly solo, piano-bass and piano-bass-drums. Sometimes I use a quartet. Just need a little oomph and presence when the room gets a bit larger and to project a tad when the crowd din gets a bit noisy. BTW – I love this instrument! Any suggestions would be most appreciated.
