Hi all, I have a Denon AVR 1909, and Im quite happy with it overall, but I recently discovered what may be a fault with my particular unit, or it may be a more general flaw with the product. Having recently got a new sub, I finally got round to running the Audyssey auto setup. It did a fairly good job, but whenever it engages EQ mode the circuitry introduces quite a lot of hiss, which becomes very noticeable at higher volume levels. With the EQ off, there is no hiss whatsoever and I get an excellent S/N ratio (+100db). Any other AVR1909 owners notice this, or is it just me?
