I have been making a power supply for some nuclear instrumentation electronics for some years. I used a Cincon power supply (9 V 6.6 A) and hacked it for remote sense. it was quiet, stable (even with my hack) and worked fine, but we needed more power. I got a 10 A supply from the same manufacturer, it was built for remote sense. It was not stable with a slightly capacitive load above 5 A, and was a HUGE EMI source. I worked on it for a while, and was not able to fix the stability or noise problems. So, two supplies from the same maker, one did what it was supposed to, the other one was barely capable of running an incandescent light bulb, and certainly no electronics. I then got another power supply from a different maker (sorry, don't remember the brand at the moment) 7 V at 8.6 A, hacked it for remote sense, and it was quieter that the original, and no stability issues.
This thing is to power a unit 10 to 30 feet away, and deliver 6 V DC at the remote load. The 9 V supplies were dropped down with a bridge rectifier (2 diodes in series). When I got the 7 V supply, I took out the rectifier drop.
