Id rather run a 400 watt amp at respectable volume then have all the welly there in reserve if I need it, than run a 200 watt at full pelt and flatten everything in the process. Also bear in mind that doubling the watts does NOT double the volume, and bass needs more power than top end does. Thats why you often see 300w bass amps alongside 100w guitar rigs, and the guitar rigs can still occasionally drown the bass out because they are projecting higher frequencies that are easier to amplify and reproduce, and (crucially) are much more directional. Also depends on the cab. An SVT through an 8x10 will knock people senseless at #5 on the master volume, but through a Hartke 4x10 it sounds a bit limp.[/quote]
i agree that bass needs more power and that higher frequencies travel further but when was the last time you played in a band with a guitarist running his 100watt full?
i've played in and played with a lot of very loud bands and i have also owned a 300watt Sunn and i have never had to go past a quarter on the master volume.
i'm currently using a modded Marshall JCM800 1959 SuperLead with 6550 power amp valves and it's clean as a whistle.
and as for those hybrids with only 100watts between them. there is no point. look at ampeg and hiwatt for example. ampeg do a 300watt and they also have/had a 100watt and hiwatt had a 200watt and a 400watt. there will be a hell of a lot of different value parts between the two hybrids.
i think 200watt is a perfect middle ground. all the Matamp users have no problems with only having 200 watts. you tend to see a lot of people say their Mesa 400+ is so powerful that they can't get loud enough to get a decent valve tone.
ideally i would of liked to of seen a 300 all valve, 300 power amp, the all valve pre and the valve pre solid state power amp heads. and of course the little bastard is a cool amp. that to me seems to tick every box for a lot of people.
