I'm considering purchasing some isolation transformers for my
hi-fi gear and am looking for some feedback regarding what sorts
of sonic benefits might be had, as well as what reasonable prices
and qualities might be.  In the summer in Charlottesville we often
have near "brown-out" power conditions with line voltages as low
as 105 (so I'm told).

My power amp is an Aragon 4004 and I'm told it operates in class B 
when the line voltage drops- hence an isolation tranformer ought
to keep it in class A more of the time, right?

So far I've seen 1 and 5 KVA units.  Both are made by TOPAZ, the
1 KVA unit is model 95210-52.  I can have them both for $150.
What do you think?

Any and all replies appreciated.  Thanks in advance.
