If budget and size are not in the equation then it is a no-brainer, get the 1000. They will sound better, go lower, have more headroom, etc, etc
I had a pair of 800s that I got because of a size compromise (i.e. WAF) - I absolutely should have gotten the 1000.
I am in the process of helping a friend put together a system and am torn between 1000 and the SM450.
IMHO the 450's are an upgrade to the 1000's. A 6.5" driver and a 10" passive, I know the 1000 has the updated driver and a 5" passive, but its what your ears hear and not what your eyes can see that makes the difference.
I have both and each has its own high point but no bad ones. If your friend is into more crisp highs and punchy sound the 1000's handle that with no effort, they also do all other music well but I hear digital better from them. If he is into a smoother and more detailed sound i.e. jazz, blues, vocals even rock the 450's offers a thick, rich detailed sound. Now as I said with the 1000's the 450 also plays all other music very well too. In my main room I had a choice of PM1000, SM350 or SM450, the 450 won out, IMHO they gave the best overall sound for movies and music. The 450's sound so good I went back and played old CD's just to hear detail I never really heard so cleanly before. Your friend can live with the 450's for many many years and may never consider upgrading, these speakers are that good.Edited by Plex - 8/26/13 at 7:28pm
