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,

I would not go crazy, keep cable purchases in line with the value of the rest of your system. For well constructed basic cable, go to Bluejeans cable. They are cheap, nice construction wire based on Belden. Typically their best quality 1 meter as RCA would be about $35.00.

The only way I would go above that would be if you intended evolving the cable out of this system and into another one. Then maybe check used here at Audiogon and buy entry level name brands that can be resold with little or no loss to test the waters.
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.
