Sorry, yes I was thinking of either the marantz or Yamaha. I have the mordant short alumni speakers which I have no interest in upgrading. Would either of these brands be a better match and would I gain a sonic improvement over the onkyo 606 that I currently have?
I recently purchased a Marantz receiver and I think it sounds fantastic! Bought it to replace my Yamaha one because I wasn't happy with it's sound. Well I can't comment on wether your speakers would be a good match, but here's a few reviews of slimline Marantz Receivers, hopefully that'll give you an idea of there sound.
