okay, on the way i have the Thiel CS1.6, and Sonics Amerigo, both second hand demo pairs, from hifi shops. the thiels i paid a premium for, and the sonics i got a deal on so they were almost the same price. =)
i haven't found the appropriate Spendors yet, and Proacs have the binding posts so high that i'd need to buy new speaker cables, as mine are 'just' long enough for speakers with connection at the bottom. i know this is a small point! still, i have to draw the line somewhere. for now i'll just A/B/C these against my existing CS0.5, and keep the pair i like best.
also, i'm upgrading my interconnects to PS Audio Xstream statement XLR, but they haven't arrived yet. [also waiting for a C.E.C TL5100 belt drive transport] so, i'll be sure to let you know how the comparison goes. thanks for all the great advice.
am i giving anyone else a case of upgrade-itis?
