Well, the mistaken assumption is that I already have an amp... I just built an Amp Camp amp, but that hardly counts as "more heft".
Thanks very much for your reply, it does give me the info I need. I have the budget for a pair of speakers and the Aleph, and will probably buy/build this. Adding a crossover (plus its power, plus its chassis) pushes pretty close to the limit, adding the linestage (plus control board, plus chassis, plus power)... , and then a second amp, we are well over budget.
