Actually I don't have a new tablesaw but my old one sure acts like a new one. I spent the morning aligning the blade and the fence and the first rip cuts were smooth enough to be glue line quality. It even sounds better and when I tried hogging the wood through, there wasn't the laboring sound I was used to. I also aligned the pulleys better which helped a lot.
Before aligning the blade I installed the PALS I bought a year ago. That sure makes the alignment process easier.
