But in that case you said thats why you opt for a dual recto vs roadster or roadking. but that doesnt explain why it couldnt be a triple.
Here's my opinion on the Triple... and it's not a very experienced so take it with a grain of salt. It's entirely based on a rhythm guitarists perspective, so lead guitarists may disagree with some of what I'm about to say.
In my opinion, Modern high gain works best with lots of headroom. You don't want much in the way of power amp compression since it'll smooth out the dynamic response of modern, which means your rhythm work won't punch as hard when you're chugging away on power chords.
To put this into perspective, the Dual Rectifier is not very loud for a 100w amp. Don't get me wrong, it's still really f*cking loud, but compared to other 100w amps (ie, Marshall) I don't think it's very loud. The trick is that with a Marshall you can drive the piss out of the power section since obtaining some compression actually makes the amp sound better, so your 100w Marshall can scream away at 120-150w and you'll sound awesome doing it.
The Recto on the other hand needs headroom. Modern high gain does not sound great with the 100w power section being driven for 120-150w. Driving the power section that hard creates a fair bit of compression, and that compression will smooth out the punchy response of modern high gain. Thus, as the volume increases the rhythm response will become more and more mushy. You'll start to get more of that "Recto wall of mud" thing going on that people complain about.
Enter the Triple Rectifier. Since the Triple has more headroom you can use it at the same volume as the Dual without overdriving and compressing the power section as hard. You can turn the amp up to 120-150w and maintain that aggressive, punchy modern high gain tone you were getting out of the Dual when it was running around 80-100w. You can now match the other guitarists Marshall without needing to drive the piss out of your power tubes.
To add to all this... lower frequencies take more power to amplify than higher ones. Thus, if you're using a 7 string tuned to A or B you'll need more headroom if you want to play with the same dynamic and punchy response you would have with a 6 string tuned to D or E.
The catch is... most Marshall users never get to use their amp with the master volume running nearly flat out, and the average Recto user doesn't need 120-150w of headroom to keep a tight, punchy sounding rhythm tone, so the extra headroom is not only lost on them, but may in fact be counter productive since the average Recto user will never be able to play a Triple loud enough to achieve any compression out of the amp.
Anyway, this need for headroom and subsequent lack of compression is why I think you'll generally see a Triple Rectifier in the hands of a rhythm guitarist, and usually one that's using modern high gain rather than vintage high gain and/or using a detuned guitar of some sort. Lead players will obviously have a different perspective, and as I lead player I actually prefer to run my Dual in tube rectified mode (vintage high gain) since it adds more compression and smooths out my lead tone for a less abrasive, more singing quality. However, as a rhythm player when I switch to modern high gain I switch also to silicone diode... even at moderate volumes that extra bit of headroom makes all the difference in the world when it comes to aggressive, in your face guitar tone.
Your mileage may vary, but that's my opinion on it.
