isolation transformer vs line conditioner


I have a single pseudodedicated line ( line form fuse box at home only supply stereo equip. & lights of that room.)
I am considering a line conditioner like BPT3.5 or shunyata hydra at the outlet vs an isolation transformer interpose betw. the fuse box and the outlet in that room.
Which would provide most bang for bucks?
Where can i buy isolation transformer cheap? 5kv topaz is more than a grand.
WHich LC is better? shunyata or bpt?

Glai, I don't know who is quoting you a price in excess of $1,000 for the 5kVA MGE Topaz isolation transformer, but I think that price is inflated by a factor of two. Try Al Magro at Allied Electronics in Bristol, Pennsylvania:

The Hydra is a filter, not a conditioner and i the BPT is an isolation transformer.
Isolation transformers can be purchased new or used on E-Bay (at a savings $).
Aball, where can I see those output waveforms myself? Or if I can't (without setting up a 'scope on my line at home), then could you describe such a waveform?

I ask because the evidence of my ears suggests that my iso trannies are doing something right.

TIA !
I think it would help to know the difference between an isolation transformer and a line conditioner. Also, it would probably help to know which one is better for typical applications.
