A simple but redunant question

[RH Customs]

I'm looking at buying a SB3 fairly soon, and I heard that changing the PS is a must. My question what is a good PS that has the correct dc input connector?

Thanks

It's not a must. Some people have reported improvements in sound quality using a beefier linear power supply as opposed to the switching unit supplied with the SB3, but the supplied PSU is more than perfectly adequate for the job. I'd advise listening to your SB3 with the supplied PSU and see what you think. I'm quite fussy and might one day play around with alternatives, but my SB2 (which is an SB3 in a less pretty box) sounds great with the stock supply.
