Aargh, my browser is having abad word wrap day.
Anyway, the other point is that a 15w amp is still way too loud. The amps that Lordathestrings is talking about (I believe) are more in the 5w category, or even less. Certainly not a practice amp, because if you look at amptone they cost every bit as much as a large amp; instead, an amp that you can crank to get that saturated tube tone, no matter what the circumstances - even in crowded flats. This then becomes a great studio amp, because you don't have to worry about cranking it heaps to get a good sound, and at a gig can be easily miked to the PA, thus enabling it to better fit into the mix. The only time an amp like this doesn't work is in a band practice/small club type setup, and then still the signal can just be sent to a big set of speakers. To get a great tube sound out of a 15watter you still need to crank it to a point that is beyond an acceptable level in most practice environments, it needs to be a lot quieter.
