Are "good" cables needed for vintage system?


I have just put together a very inexpensive 2 channel semi vintage system. I Have maybe $700.00 in it total. It consists of a NAD 1020b pre, NAD 2155 power, Pioneer PL-112 TT with shure M97xe cart, sony HD dvd player to use as a CD player for now, and it all comes to life through a set of Pioneer HPM 150's. I'm running crapshack cables right now, and I'm wondering if upgrading the cables is worth it on this old gear? Surprisingly I do enjoy the sound I'm getting to a "point". But that's why I'm wondering about upgrading cables. Can I get it past that "point"? As you might have guessed, I'm not going to spend much on cabling, but if it'll help, I'll start serching for used stuff.
Any ideas on this thought guys??
What cables would you recomend?

Thanks for you time,

Keep it reasonable: Anti cables work very well for me in my Vintage system...Sansui,KLH,Sony ,,,,,,Always good used Anti Cables around
Good advise above. The improvement wrought by the actual higher quality RCA jacks will probably be most helpfull.
If you are somewhat handy you can check out the many DIY cables out there and really get the most for your dollar. I have made a few for way under $100- and they sound almost as good as cables that I spent $500- on.
'good' is a relative description, but most systems (vintage are not)will sound fine with radio shack connects and wire.
.

I have a set of Ridge Street Audio Poiema ICs RCA and Morrow SP2 SCs on a C41/MC225 monobloc system with Tannoy DC3s... VPI TT (Morrow PH2 ICs) and MacMini/iRoc DAC (RSA Poiema USB cable)....

and the cabling makes a huge difference... worth every $... lifelike, detailed, musical, simply awesome in every respect.

Also the impedence match between the C41 and the C225s brings a nice synergy that cabling enhances.
