Thanks for your reply Hunter!
Yeah i know that the volume of my power amp effects the wetness of the signal, but i have a feeling that 2 cabs are tougher to blend to my ears (the dry one has g12h30s the wet one g12m25s) so it may be better on one cab as a "stereo".
Taking the chance, let me describe my current Dry/wet setup as a reference for others interested (but also to hear some suggestions on its improvment). Guitar goes directly to DSL50 input, (no fx on the dsl50 - the dry part) DSL speaker out to THD hotplate and from there to a 1960a cab with g12h30s 70's anivvesary. From the THD's line out goes a cable to a TC nova modulator (or several mxr evh stompboxes depanding on the mood) and from it to a boss DD20 and sometimes a RV5 and then to the power amp section of a TSL60 (fx mix to full with clean channel selected, volume of, as to bypass completely the preamp section of the amp) and finally to a framus dragon 412 cab with g12m25s.
So volume wise it not the uncontrolable moster that some describe, at least in comparison with other tube mashall stacks. Yeah i will try before i buy, dammit i just lost an opportunity to buy a 2 year old 800RI in mint condition (played only in a bedroom enviroment also) for 800 euros and very close to my home. When i found about it, was already sold to someone else. :(
Oh well... i guess that in about 25 days...i'll buy one...new :D
