Beyond that, if you played it and liked it, look around at amp's that have a similar price tag and play them too. Other people opinions are great, but remember, yours is the only one that counts. It's your music make and play it the way you want.
Incidently if you already have a higher powered capacitor amp and you still want to record with a lowly 15 watter, it may be a sign that you need to get rid of it and buy a tube amp. You obviously like the sound better.
