Speakers on short or long wall?

In response to everyone, room  acoustics will be hard surfaces speakers will be on long side of wall I have had my B&W 804N for 14 yrs just want to upgrade Really looking for a good match with NAD M25 amplifier don't want to waste money on to much speaker  2ch. music only.

Still not sure what "upgrade" means to you. What do you think could be better (or just different) -- bass, midrange, highs, volume, clarity, dynamic range, imaging, physical appearance? That list could continue, but hope you get the idea.

Here’s a pair of Joseph Audio Pearls in your price range. They will blow away your 804s in every conceivable way.

Or for quite a bit less these AZ Crescendos would also be a big upgrade.

Right now, your Speakers are nowhere near reaching their potential for better performance (meaning you truly haven’t heard what your Speakers are capable of yet). The only reason to change the speakers is if you don’t like or are offended by their tone.

It would be like having a Martin Guitar and trading it for a Taylor or Gibson. Do you want your guitar to sound better? Hand it to a better player. In this case, put better Electronics and cabling in front of those speakers and help them reach their true potential.

After you live with that a while, then you might want to explore finding a better sounding instrument (Speakers).
