Yeah, I know that isolation in a lot of cases is not required at all and for most people, it is not an issue, but I am gigging regularly and I had problems. If you have no problems a filtered PSU is enough, it's much cheaper, no reason to buy expensive stuff.

The Boss tuner that I have on my board is dumping a ton of digital noise to ground and without isolation, even my small pedalboard became noisy when I was using only a low gain overdrive.
Also, in a lot of clubs, where power was crappy (crappy wiring, phase issues, etc) I always had problems with ground loops, etc..

All of my noise issues went away with an isolated PSU, the whole rig is dead quiet now, so that was the main thing that started me to experiment with this.
