What Power isolation transformer or conditioner similar to Topaz

Hi,

I know the improvement of power conditioner is a huge YMMV, but that means I have to try it out myself.  And the question is, what should I pick to try.  While researching, I come across a thread from head fi about Topaz isolation transformer with 0.0005pF capacitance.  I like it because it has such technical details that I can’t find in any other similar products.  However, it is not for internal use as there may be humming.  If I buy it, it seems I need to do more work to build a case to cover it.  Is there any other product that stated the capacitance, and is designed for internal home use?  
Thanks.

As for capacitive, capacitance, coupling.

https://en.wikipedia.org/wiki/Isolation_transformer

Isolation transformers are designed with attention to capacitive coupling between the two windings. The capacitance between primary and secondary windings would also couple AC current from the primary to the secondary. A grounded Faraday shield between the primary and the secondary greatly reduces the coupling of common-mode noise. This may be another winding or a metal strip surrounding a winding. Differential noise can magnetically couple from the primary to the secondary of an isolation transformer, and must be filtered out if a problem occurs.
