Thanks to all of you for your valuable comments and suggestions. I own the Pass x 0.2 preamp and speakers are 91 db- audio physics caldera ( three cabinet- first version). My room is 15" x 12" x 7.5" at present and in a year will be 23.5 x 12 x 12. For now I will keep the aleph, although I agree on the lack of control in the low frequencies. I am still fascinated by the ease of that musical flow the aleph delivers, but will give the xa 60.5 a serious in-deep listening. To edwyun: what do you mean by SW?
