… do yourself a favor and purchase an APC 600, one of the light tan models, not the noisy, smelly onyx models. Do not run it from the PP 2000 , run it from the wall. The PP 2000 will then shelter your other components from this newest insult also. I will be interested to know if this new APC also provides hum.
A few things I would like to note in context of the post above. You need to be VERY careful connecting the switching power supply in series as it significantly drops power handling. Second, neither PP 2000 or APC 600 provide ground loop hum, it is imposable by definition. Third, what is the need for additional powering of TT’s motor. The TT motors all have power stabilizer in there and they run from let say 5-12V. Yes, I know – there are people who feel that special powering of TT motors does make difference – I find it is a controversial observation.  The last one – the APC 600 is line-Interactive unit not the double conversion unit. Those units produce truly garbage voltage, good only to power irrigation systems. It is very unlikely that it give any benefit and it certainly not the tool do break ground loops.
