Isolation transformer

I used a Topaz isolation transformer for a few months but have since removed it. The reason is my incoming ac voltage fluctuates between 119 and 127 volts. The output of the topaz had a 2 v gain so when I would have 127v in I would get 129 out. Too high for my tube amp.

When it was in I had a slightly lower noise floor. The other factor I did not really care for was the parisitic power being used. What I mean is with NO LOAD it was very warm and I figured it was using about 90watts.

Xti16, a very interesting post and perspective of isolation transformers that most people don't even consider.

I appreciate your input even though I am not in the market.

Glai,
As with most things concerning home audio they`re many individual experiences. I`ve used a BPT BP 3.5 Signature Plus (balanced transformer similar to Equi-tech) for close to 3 years. It has been an oustanding addition to my system and all components are plugged into it.

The noise floor is lower.dynamics,inner detail/nuance, musical flow,liquidity and sense of ease are much improved compared to wall outlet(20 amp dedicated lines). In my system I have`nt experienced any negative effects. I`m a strong supporter of balanced electrical power. Unlike the above poster, this unit is cool to the touch(24/7 use) and there`s no hum issue. As aiways YMMV.

Best Regards,

Didn't the Topaz have different taps to adjust voltage a bit? I am pretty sure my MGE ultra isolation transformer does. It does cook some, but it is way over sized. I use it for my computer and hardrive on a digital front end. I didn't care for it on the analog stuff- it killed the PRaT. It is rated at 1500w too btw.
