so you're telling me these Mesa MKIIC+'s, MKIV's, and Dual Rectos just blow the Triple Recto out of the water? how about the Engl's and Diezel's, do those stack up any?
Rectifiers are, honestly, mediocre amplifiers at best. The Mark series amps, especially he Mark IV, blow all of them out of the water. If you're dead set on a Rectifier, go for a single or a dual, unless you plan on playing in stadiums with no PA system on the clean channel.
Keep in mind that wattage has little to do with volume. A 150 watt amp will have little difference in volume compared to a 50 watt, and that difference will only become apparent when the pre-amp and master volume knobs are on 10. Wattage is really more a measure of headroom, or how early the amp will break up. Considering that the "tube sound" is largely powertube distortion, a low wattage amp will tend to sound better (unless you need crystal clear cleans at high volumes, in which case you might want to look at higher wattage amps)
I've never really been a fan of any of the three brands listed (I'm not a metal player, and I just don't like the voicing of those particular brands) but ENGL is definitely something you should look at. As always, don't buy anything until you have a chance to try it out.
