i had the totem arro in my rig for a few days, & i also heard the kestrals quite a few times in a system i knew well. both are really nice, but i would take the proac 1sc or ref 8 sig over either one of them any day. the arro's pooped out when cranked, even when crossed over to subs at 80hz. the ref 8 sigs, on the other hand, would easily generate concert-level volume in a 26x38x8.5 room in the same system w/the subs. (so would proac tablette 2000 sigs i had in that rig for a few weeks.) the kestrals, in a different system, were certainly nice, but couldn't compete w/proac 1sc's in that system, in terms of resolution, air & soundstaging. and these three aspects are where the ref 8 sig surpasses the 1sc's; the 1sc's only adwantage over the ref 8 sigs is that last little bit of extra low end. but, even in a 14x22x10 room, i would choose the ref 8 sigs over the 1sc's, even w/o a subwoofer. now, i realize that the proacs really do not qualify as $1k speakers... in this case, i would check out the usher line, as the sound is closer to the proacs, imo, & the pricing is much more favorable...
