Speaker cables where to begin?


I have a system I am comfortable with so far I believe the cables are the weakest link.

I am currently using transparent audio music wave cables in 15 foot length. Unfortunately, I can't go much shorter possibly 12 feet but that is stretching it.

My system consists of and Accuphase E-408 integrated amp, Transrotor Darkstar TT with JR arm (AKA jelco 750D) benz micro glider 2 Low output cartridge using the Accuphase AD-20 card. Other components are an Accuphase T100 tuner and Arcam DV29 for occasional CD listening.

Everything is run through a Richard gray 600 Pro. Interconnects are older straightwire.

I am not looking to spend a fortune on cables although I was thinking I should use a biwire terminated end for the speakers. I guess the question is what would do the best for my system 1st vs what is most economical improvement? Some day I am sure I will make other upgrades but for now I am looking at speaker cables and possibly power cords and what would do justice to my system.

I did notice an incredible improvement in CD sound quality with the addition of the RG 600. Should I expect an equal improvement from both TT and CD with speaker cables?

Thanks

Usedcable.com's demo cables are already broken in. They carry almost every brand. The deposit can be applied to your purchase. They are a business after all. Why would they maintain a data base, risk lending you cables, and then have you purchase elsewhere? Put yourself in their shoes. Either that or randomly purchase and sell cables at various lengths and condition here on Audiogon, keep listening notes, and then hope the ones you liked in the length you need shows up in a timely fashion.
I recently purchased some Blue Jeans speaker cables for my parents and own a pair of Morrow SP3 cables. The difference really was not that great. The Morrows are cleaner, a bit more refined and offer a better level of detail.

The difference was greater with my Kaplan power cords and Running Springs Haley. However, the IC's from Blue Jeans were a degradation in sound quality. However bear in mind, i did not have the Blue Jeans IC's long enough to break them in, nor the speaker cables.

The best speakercables you can give any transistoramp are thick massive and as short as possible. Resistance are the enemy, try to find some really thick copper and give it a loud burn-in and you`ll never look back.

Be prepared for a dynamic experience ;)
