The short answer is, yes, esp. for classical that has large swings from ppp to fff.
The most important thing is, why: in order to produce sound pressure yr spkrs use the energy provided by the amp, so more W capability -> better rendition of musical dynamcis before the amp clips (runs out of steam, as it were). In this respect, however, a 100/w/channel amp will add ~20db spl to yr spkrs' nominal sensitivity (if memory serves for the 801 this is supposedly 87db/1w/1kHz), while 120W/channel will give you LESS than 1db spl extra.
The ONLY reason one would go with a 120-150-200W/channel rated amp, rather than the 100watter is that the slightly higher rated products would "play" those nominal 100W (if that's what you really need most of the time), "BETTER". This is due to the current (ampere) capability of the higher "watt" rating. In order to spec the watts, the manufacturer SHOULD provide an adequate power supply for spec'd watts (or it's misinformation), so the PS design for the 120-150, etc W rating will be "bigger" than the 100W rated one.
Hence what Marakanetz seems to be suggesting in his cryptogramme above: you're better off having, say, ~400W power amp rating/channel, and if you did have that, you'd notice that the result is noticeably better (i.e. 400W will give you 26,02 db spl over the spkrs' 1W sensitivity, in text-book terms) -- if you didn;t cook yr spkrs that is, as few drivers can withstand 400W for more than a few milliseconds.
HOWEVER, all news isn't bad and be advised that yr room is small, so the upper spl limit you'll probably require from yr system will be lower than it would have been in a much larger room. As long as you listen to a ppp at around 70db, you be OK with the fff in Mahler 2 (Klemperer preferably)!
