i have read the old threads on this but im asking again in case of any new input.. new to this vintage stuff. i have a sx-550. sounds great and i like it, like the pioneer stuff .. looking for a new bigger system.. from my reading on old threads, the spec stuff seems to get a be preferred over say the sx-1250.. was going to try to get one of those til i read and saw most prefer the spec systems.. what would be the ideal setup for them? or just go with the 1250... and speakers? now im leaning to trying the spec stuff..
