You say high current drawing. But how high is high?
If you truly have high current or even medium current drawing amps, each amp really should be on its own dedicated circuit/line otherwise the chances are great that each amp (or other components sharing the same circuit) will choke the dynamics right out of the presentation for the other amps. A 26 watt preamplifier is enough to squash the dynamics out of 'high' current drawing amp so I don't know how you can work around that one. Except to acquire dedicated line conditioners and have an electrician install dedicated circuits/lines or get 'low' current drawing amps.
Secondly, and perhaps most important is the quality of the line conditioner. As you probably know many/most line conditioners simply are not worth owning as they do nothing at all, induce their own sonic harm, and/or rob 'high' current drawing amps of the juice they require because the line conditioner is active meaning it's drawing juice to itself and away from the amp that desperately needs it for loud and/or complex passages.
The difference between line conditioning and proper line conditioning is night and day. Regrettably, a good rule of thumb for line conditioning is, if it's a popular name brand, keep searching.
-IMO
