Isolation Transformers

Re-Posted under this Topic

My wife and have sold our home and are renting for the next couple of years. Therefore, I don't have the luxury of re-wiring, dedicated lines etc. I am looking to clean up the AC supply, minimize the effects of other household circuits and get some surge protection.  After quite a bit of reading I have narrowed my selection down to an Equi=Tech 2RQ or a Torus RM20. I can buy either unit for a 30 day trial/refund but would like to make a good choice to start.
My delima is this. The Equitech offers balanced power on the output which would be effective at canceling reactive currents between my audio components. It also offers filtered outlets for digital gear and would isolate my entire system from the rest of the home with its own ground reference on the center tap of the secondary. However, it does not have any surge suppression built in other than the transformer itself.
The Torus on the other hand offers SMSS which gives me peace of mind. It also has Plitron NBT for line filtering. However it lacks the balanced output, and therefore would not isolate my system from whatever grounding this house may, or may not have. The Torus also does not offer any filtered outlets for digital gear.
My system is: Klimax LP12>Erika Phono>Pass XP-22>Pass X250.8>Thiel CS2.3  with a MacBook>Chord MoJo>Pass XP-22 for digital files. I will upgrade the digital end some day so I like the option of digital outlets with the Equitech.
If anyone has experience with these isolation transformers I would appreciate some direction. Thanks
