Hmmmm......Good reply, but I feel like I need more info. What I was thinking of doing with either amp was to install KT77's into a Stiletto or the 6L6/EL34 combo into a Mark instead of doing straight EL34 or 6L6 into either amp. I do need a little low end, my stlyes are broad, from GnR and/or classic rock to some of the newer stuff (I'll use Creed as an example, even though we don't go there).
Honestly before you go changing anything around I'd get to know the amp with the stock setup. Part of the beauty of those two amps in my opinion was that you didn't have to really do anything but plug your guitar into them and they're perfect. When I had a Dual Rec I was never happy with my tone one day and thrilled the next, I tried tons of tubes, etc.
The Mark IV w/ EL34s and 6L6s might be the best of both worlds for you as far as sonic options because you can do pure EL34's or a mix of 6L6's and EL34's. The Mark puts out a ton of bass already if you want it to and so does the Stiletto with the right settings. I think you'll find the EQ a LOT more usable with both amps compared to your Rectifier, especially because on the Mark you have the graphical EQ which you can set for your low end fix and then stomp off it and have a different sound without doing any tweaking at all.
