Are Cheap XLR Balanced Better Or GOOD RCA

I'd go balanced. Likely a trade off given your constraints right now. Some XLR cables don't cost more, like Cardas. Depending on what type of sound your're looking for, Cardas Neutral or golden ref might a a great choice.

Transparent is another, but their xlr cable are twice the cost of rca's.

Benefits are much lower noise floor with balanced connections...

It depends on the length of the interconnect. If it's longer than one meter, then you _may_ hear an improvement with balanced. If it's one meter or less, though, I doubt you'd notice a difference in a double-blind test.

It also depends on the type of cable used. The RCA interconnect you already have is very good. If you use a REALLY cheap balanced interconnect (like a pair of generic microphone cables) you may actually be taking a step down in performance.

For the money, I think Cardas' bottom-of-the-line balanced interconnect is a terrific value. Even if you need a fairly long run, the cost would be minimal.

Some of the Japanese pro balanced cables can realy honestly perform meaning transfer from one component to another in the newtral media. Their performance is great for the price offered.

In the Levinson setup balanced connections give you more gain in the amplifier coming through your speakers. Better sound - maybe depending on the cables. Borrow some cables from a friend to see if its worth it.
