Long interconnects or speaker cables?


I've just purchased a new amp and may need to reconfigure my listening room and I'm wondering, which is better a long interconnect run and short speaker cables or the opposite? I'm running the preamp out jacks of a Bryston B-60 into a conrad-johnson premiere 11a.

Redkiwi's description the long IC/short speaker cable or vice versa issue is the most tersely eloquent summary I've encountered and I thank him for that. I'd only add that the preamp section of the B-60 outputs more than enough voltage for 8 or 20 foot interconnects. Cheers, Joel.
Tom with what brand of cables did you experience that? Curious, because if you're using network-terminated cables (Transparent, MIT) the deleterious effects of cable-lengths is supposedly compensated (I was told). Could be true? Anyway, if using a passive preamp, then long interconnects are a problem at least from my experience. YMMV
Short speaker cables help retain the micro information or the ambiance of the recording. Use long good quality interconnects with short top quality speaker cables. I have 1m50 Wireworld Eclipse III speaker cables and a run of 5 meter-long Wireworld Equinox III interconnect.
This is especially true if you can use balanced (XLR) interconnects. Knowing where I'd like to place my speakers and what speaker cable lengths this would require, I chose my equipment because it could accommodate long (XLR) interconnects and allow short speaker cables.
I am just curious but has any one tried to get the amp's close enough to the speakers to try a gold/silver bus bar? I can not due it with my set up but would be interested in the performance even if it turns out to be bad.
