Fully Balanced Isolated AC Mains Power Conditioner

The Holton AC One provides the ultimate in audio grade balanced AC mains power isolation and AC mains conditioning.

It works by taking the unbalanced AC mains voltage and converting it to true balanced AC mains voltage on the conditioner outputs, minus DC Offset, most of the common mode noise and interference. But before it does this the AC mains coming into the conditioner is first passively filtered for HF noise before it is passed on to a high power version of Holton Audio's DC Blocker One. This removes any DC Offset before the power is applied to the 3KVA power transformers unbalanced primary input. 

True Balanced AC mains power offers a number of advantages compared to digitally synthesized AC mains reconditioning.

Customer Testimonials:

Good morning, Anthony.

A quick note to let you know how the Holton Balanced AC 1 Conditioner i purchased has performed. Having owned a Isotek Sigmas GII power conditioner in the past which did not perform to my expectations i was cautious as to making another power conditioner purchase.

The Isotek unit had a less than satisfactory effect on the amplifiers i was using even though it had two high power 16amp inputs specially for large amplifiers, cd and sources were a mixed bag on the Isotek producing a lower noise floor but producing a thin and uninspiring soundstage. 

Through research I found many instances where power conditioning was not recommended for power amps so where to from here.? With consultation from owner/designer Anthony Holton we discussed the design and benefits of balanced power conditioning, this gave me a solid understanding and what to expect, when dealing with Anthony there was no sales pressure or over the top claims. Now to the performance of this remarkable power conditioning unit, at 30kgs it is no light weight with a 3kv transformer and heavy steel construction, the soft start power button on the front panel is of high quality along with the vu meters showing amps and grid voltage. From the moment i switched it on and commenced listening i knew i had made a vital choice in cementing a rock-solid foundation for the sound quality of the system. No loss of dynamics, improved bass response and lowered noise floor were noted, the flat panel tv also showed the power conditioners abilities with improved picture quality. Make no mistake this Balanced One Power Conditioner is the real deal. I would like to personally thank Anthony Holton for producing such high-quality products for the discerning audio enthusiast, a pleasure to deal with, a technician of the highest order. Thanks so much.

Kind regards Phil. B. Turners Beach. Tas

Hi Anthony

My AC One is now installed and it has produced an immediate positive effect! Very Impressive!

Whatever thick blanket there was over the sound has now completely gone. it is so much better in all of the normal metrics we would use to describe the overall sound quality.

Even my QLED TV is much sharper and better contrast ratio and better detail, even the audio from the QLED TV has improved.

Hi Anthony

Just got my AC One! Thanks so much - it looks (and weighs) like it was hewn from granite!! Amazing!

Forgot to say it sounds amazing, too. Definitely blacker background, intermittent DC offset gone, power amp transformer slight hum gone too!
