what mid priced cables should i buy?


i have a brand new integrated krell 300i and a brand new rega planet 2000 cdp and 6 months old bose 901's (speakers)
(i think those 901's r my weakest link so far)
that whole system is connected with low end cables (interconnects and speaker wires worth less than 50 bucks alltogether)
1. i want to spend 350-450 dollars for cables, any suggestions? i dont know much about cables (and frankly im quite skeptic) but i've heard that mit terminator 2 speaker wires r decend, any input?
2. is buying used cables a smart thing to do?
3. the bose speakers has an external EQ\crossover ,
that is hooked up to a tape monitor loop onto the krell 300i
that requires 2 pairs of single ended interconnects,
is it important to upgrade those interconnect as much as the interconnect between the cdp and the integrated amp>?
(should i spend the same amount of money on the tape loop I.C as the krell to the rega I.C ?)
thanks for your help
happy holidays for y'all

Dave, Seasons' greetings back at ya. Sean is giving you very honest advice here. The bose 901's should go first. They are the weakest link....sorry....cheers, bluenose
Sean is right, even if all those crappy mid range drivers and flexy cabinet in the 901(they will never give you an image,too many reflections, and why would you want to let your room react with the signal like that?) could do much good, that Bose EQ is horrid! That thing will destroy the sound of anything you hook it up to. Your other stuff is quite good but that thing will make your Krell sound like the worst 60's IC solid state stuff. Spend $200 at Audio Advisor on a pair of Sound Dynamics rs3's. Then get some cables. You won't beleive it
You speakers are even lower end than your lower end cables.Dont sweat the wire.Like Sean said Save your cash and get new speakers
I'd better spend $350 on some decent bookshelves and use a regular $10 RadioShack speaker wire than spend extra for some high quality cables -- WAKE UP bro!
