What's my next step in AC conditioning??

Uri: the Monster has a schematic diagram on the underside. It has two filter circuits, each using two inductors in parallel. The power amp is best plugged directly in the wall using a cryo'ed outlet. Later you might want to try something beefier, but for now let's keep things simple, in balance and within a reasonable budget.

Here's a review from someone that followed my suggestions:

Power conditioning and cryo treating

I am not a huge fan of multiple dedicated lines, as that can bring ground loop issues. My system runs on just one 30 amp, 220V dedicated line and I use step down isolation transformers. It works.

These are the steps to doing this:

1) Power delivery
2) Cleaning of power
3) Preventing cross contamination
4) Not ruining the music in the process.

You have made a substantial discovery: the benefit of a dedicated line. Cross contamination from outside sources and power delivery improve. Now you need to do steps 2, 3 & 4. Step 1 is finished off by getting a Porter Port. Lak says it's the best outlet he's tried--and believe me, I've been to his house several times. He's got every outlet out there and a set up consisting of six dedicated lines.

I would get one or two smaller ONEAC (2-3 amps)isolation transformers from eBay ($15-30)and plug them into the Monster to isolate digital and analog. The Monster has two separate filtration circuits, so I'd use one for digital. Adding a small ONEAC for the digital will surprise you as it outperforms filters costing hundreds of dollars.

Search the archives, as this is extremely application specific. No set route, no set products.
