long speaker cables or IC's for budget system

I am planning to rearrange my room so that my stereo rack is in the back corner of my room instead of between the speakers. The issue this creates for me is which cables to switch out. I could leave the amp between the speakers and run a 25ft pair of IC's from the amp to pre-amp or move the amp back to and run a 30ft pair of speaker cables from the amp to speakers. I currently have MIT T2 interconnects between my amp and preamp (1meter) and have 8ft MIT T3 speaker cables. The problem is I am only giving myself a $150 budget which has me looking at Blue Jeans cables. Am I hurting the sound quality of my system by downgrading cables? Please take a look at my system to see a list of my components. The only upgrades that I plan to make in the next couple of years would be switching from 1c's to Vandersteen 2Ce Sigs and maybe upgrading the turntable as well. Please factor in my future upgrades with your suggestions. Thanks in advance for the input.
Keep the amp between your speakers and buy or better yet make your own interconnect from Belden 1694A or Belden 1505F with Eichmann Silver Bullet RCAs. The BJC LC-1 is also a very good choice in your price range. You will not be disappointed or notice any loss versus spending more. IMO.
Long interconnects and short speaker cables. I have been using a 25' interconnect for years. I tried switching to long speaker cables and immediately switched back.
Wow ...so the conventional wisdom is shorter speaker cable?....I ve had 40foot spsaker cables all along...but not visa versa :)...something to think about
Great. Looks like it is close to being unanimous for the interconnects and I can accomplish what I want for cheap without a loss in sound quality. Thanks to all for the input.
Not so fast. It depends on the cables, the amps, what proceeds the amp, whether the system is connected via single ended or balanced, and the environment in which the system resides.
While it is often said that one's gear is better not placed between the speakers, putting it in a corner might be worse. I can't help but wonder if you would be better off leaving things as they are.
