The Denon 330 was the first receiver that I purchased as "future proof". I finally had enough of the big receiver companies failing to deliver on promises and went with a dedicated pre/pro. Anthem has a proven record and Arcam is making promises to keep gear up to date as long as possible. Sherwood/Newcastle added the snap EQ function for a 100 dollars which would have been nice if it worked right. Actually Acurus had a pretty big upgrade a year after the model was abandoned. Can't forget about Sunfire(they say the box is now full and won't offer anymore), Lexicon and Meridian. It can be done, at a cost of course. The common thread is that none of these are receivers. Next time around check out a dedicated pre and see if it would work better for you.
