feliks -- how loud do you listen in terms of dB level? (Forget the subjective terms of "loud" and "moderate" as those mean different things to different people.) Get yourself a sound level meter if you don't already have one. Power and loudness are in a logarithmic relationship. This means that once you get to a certain volume you can run out of power very quickly since each 3 dB increase in volume requires double the power.
I use a Schiit Aegir which has 20 watts a channel (8 ohms) and very easily drive my 88 dB sensitivity speakers to my desired max average volume (80 to 85 dB, C scale) with plenty of headroom. When I first got the amp I used to VTVM to monitor the amp's output to see if I was running short of power and discovered the combo was just fine for me.
That's the key -- find what works for you. I realize there are a lot of members of the "more watts is always better" club but that's not the only way to do things.
