hmmm... well, just do what makes sense and is proven to be a real problem.
If person X has been using these super-adaptors since his grandfather has been using it - that does mean that its all-right, its okay. Same goes when observing herd mentality - a lot of people think so doesn't mean its right.
If this whole supercharged adaptor thing is really a risk - say, it can kill pedals, no filtering, not fuse lah, etc etc - then get rid of it. But do you need a 1k power supply? Probably not... what makes sense could be that Fuel Tank Jr.
The main reason why I changed the last time was due to the problems I faced with noise. I switched to a Voodoo Labs PP2+, noise decreased quite a bit & tone changed for the better. Later on, I read a little more and realised - hold on, those super-adaptors could have actually damage my gear. So thank God I did a swap earlier.
