Thoughts and Ideas on Battery Powered Amplifiers?

I am looking for a high-quality battery powered amplifier. I have seen a few listed on eBay and one from DIY Kits but I figured I would ask the crew here to see if such a beast exists. The power to my condo is noisy and fluctuates between 100 volts to 122 volts. The frequency is solid, relative to the voltage.

I would rather invest in a battery system than big $$ on line cleaners and isolation. I have a medical grade trip-lite line isolation box and step-up/step down transformer that was used for NMR machines at the U of I lab. It does OK, but I think DC to DC is the way to go for purity of sound without huge $$ on electronics.

Any thoughts? Under $1k for vocals, singer/songwriters, blues and loads of jazz. This will be used with Totam Hawk speakers, McCormack Line Drive passive preamp, Linn Sondek LP12 and Ray Samuels Nighthawk battery phono preamp I am about to order.

Thank you in advance – D

I have a battery powered Tripath Class D amp that sounds as good as any amp I've ever heard.
Custom made with all top quality caps, WBT inputs, and Cardas speaker outputs. 45 wpc at 8ohms and 90 wpc at 4ohms.
I am very happy with it.

Some would switch from LP's to 45's then.

I'm sorry, your voltage fluctuates between 100 and 122 volts??

Where do you live???

If it is anywhere in the USA, that is a serious issue and should be reported to the local utility.  Since I work in the utility industry I can tell you they take that seriously and will respond by checking the voltage in the area and your unit and will repair or replace transformers and other components to make it right.

Write to them and let them know the problem (make sure it's in writing) and use the word safety issue in your letter.  

If it is anywhere in the USA, the utility is obligated by law to provide safe and reliable service.
