a very good of mine, now in U Berkeley, always wanted to get what i have for audio gears. he knows nothing abt audio, but knows my gear sounds good. i just told him how good my new RTI6 was now he wants a pair 
he live @ U berekely campus but friend is able to drive him up to SF. any good store or even better price to recommend?
2nd thing is since these are unpowered, but good bass response. what is the cheapest/most affordable amp to have for RTIa3? (i would say less than $200 would be perfect), and where to buy them? he likes the "pay and get", not internet shopping.
hes using them on computer desk, with creative X-Fi soundcard (was not bad).
