I own 6 of these iso-trannis and never noticed any negative effect in a low power SET/high(ish) efficiency system.
But if there turns out to be a problem, simple to a search for "mu-metal" and either buy a mu bag or ox to place over the Topaz. Mu-Metal was created specifically to block stray magnetic fields from motors, magnets, transformers, etc.
Check with Mapman here on Audiogon, I recommended he use some for hum he was getting whenever his phono stepup amp was near other components. It solved the problem for a just a few bucks
The EMF Safety Superstore sells several different types of Mu-Metal or equivalent shielding products from $2.50 per linear foot to super expensive. I'm sure they could recommend just thing you need.
Gauss Meter sells minimum orders of 3 ft @ $24 per. (half-way down page)
