Ok,
my dealer checked my 588 and said that transport should be replaced.

he said that he won't do it free of charge as i'm not an original owner :-(

i e-mailed to Meridian a serial # of my unit to see when the warranty should expire according to their records.

unfortunatelly it seems like a way too big challenge for them to answer my mail :-(

i recon that about a year ago my similar mail to Krell was answered within 3 hours - that what can be called "real service".
