PLiXiR Elite BAC 1500 Balanced Power Conditioner

PLiXiR Elite BAC 1500

Using a custom-built transformer from Noratel, the Elite BAC 1500 by PLiXiR cleans up your AC mains supply for electrically sensitive equipment to help your setup achieve greater clarity of sound. It is the next step up in power from the BAC 400, delivering up to 1500W of Pure Tone power. Unlike the BAC 150 & 400, this product is suitable for use in a regular hifi setup using a power amp.

What PLiXiR say

The PLiXiR Elite BAC 1500 power conditioner is the best mains AC power conditioning product for your Hi-fi system; 1500Watts of Pure Tone* power capable to support up to 250W per channel stereo Hi-fi systems. It is designed to naturally reduce the incoming AC mains noise while improving the current delivery to your system. Based on a custom single winding balanced power transformer, ground loop current and noise is reduced to negligible level to equipment connected to it, making it suitable for sensitive equipment like turntable and phono stages. It is the ultimate grounding box for your whole Hi-fi system.

Features

• Casing: Extra rigid aluminium vault casing – Thick precision extruded and CNC machined aluminium slabs form the casing for the PLiXiR Elite BAC 1500. The bottom plate is a hefty 8mm thick plate of aluminium that anchors the whole casing.
• Vibration Control: Isolated by Bfly Audio - Bfly Audio's Master Pro-Feet Series isolation footers from Germany are installed onto PLiXiR Elite BAC 1500. They isolate the Elite BAC 1500 from the ill effects of self and environmental vibration and contribute to the natural sound of the Elite BAC 1500.
• Master-crafted: Build and tested by Mastercraftsman -- Each BAC is hand-made by a master craftsman. As much as possible, all electrical connections are done by point to point direct soldering with minimal use of connectors and joints that degrades sound.

True balanced power can only be attained if every component along the chain is purpose-built for such transmission. Mating Plixir’s Signature Balanced Power Cable with Plixir’s Balanced AC Conditioners and Balanced DC linear power supplies, we now have a total system and solution for balanced power transmission – the world’s first fully Balanced Power Delivery system.

The new Plixir Signature BPC is custom designed from the ground up for balanced power delivery and transmission to your Hifi equipment. When used in conjunction with our Elite and Elementa BAC Balanced Power Conditioners, noise is rejected throughout the whole chain, right up to your equipment.

PureTone

From concept to design, the goal for PLiXiR products has been clear: the accurate and natural reproduction of PureTone.

• A violin should sound like a violin, the magical interaction between wood and string.
• A trumpet exhibiting the glorious metallic tones of the brass from which it is crafted.

Whether it’s a bright and brassy musical passage, or the sharp tones characteristic of a vocal singer, PureTone accurately and unbiasedly reproduces all the nuances in timbre – nothing more, nothing less.

PureTone is all about going back to the fundamentals of music – when music starts to convey its meaning and stir our soul, so that we begin to understand and emote with the music, no matter the system resolution. And without artificial sweeteners to smoothen and colour the sound.

This is PLiXiR's goal, the pursuit of Pure Tone.

BAC Power Conditioning

But first, some theory. Power conditioning and system grounding profoundly affect sound reproduction, yet are poorly understood.

What one hears from their hifi system is the conversion of energy from the AC mains to the DC power supply of our equipment, which it then draws upon to amplify the music signal.

Under ideal conditions, AC power drawn from the mains supply is a smooth, sinusoidal wave. Following this, the “perfect AC/DC converter in your equipment will output flat DC voltages.

In reality, AC mains is noisy, and this noise will leak into the DC power supply and subsequently into the audio signal that you hear. In conventional electronic circuit design, steps are taken to reduce this noise, but it remains insidious and will find its way into your system.

System Grounding

This is often confused with the safety earth, which is different and is meant to protect you from electric shocks in case of equipment failure. System grounding, instead, provides the zero reference voltage level for all signal and power voltage in the hifi system.

Ideally, for the best sound, the two are electrically separated, with the signal ground generated from the AC/DC converter, and the equipment casing connected to safety earth. This is because noise levels in the Earth will directly affect the system’s ground reference voltage.

In the real world, for cost and/or expediency reasons- e.g. to pass EMI/EMC regulations- the safety earth and signal ground are electrically connected. This causes earth noise to leak into signal ground and high-frequency EMI/EMC noise to leak into Earth. In this way, noise levels in the Earth are mashed together in a complex web in a modern-day hifi system, creating noise loops that affect the sound quality of the system in a big way. This is why grounding and earthing products are becoming more and more important.

PLiXiR Balanced AC Power Conditioners

Because power and grounding have such a profound influence on sound, we are determined to solve the issues of power delivery and grounding of the equipment naturally and organically in accordance with our Pure Tone philosophy.

The PLiXiR range of Balanced AC power conditioners provides fundamental grounding solutions to your system while naturally lowering down the system noise floor to allow even more harmonics to come forth, without sacrificing dynamics. Most importantly the tonal structure will be intact and improved, not shifted.

Balanced Transformer Design

Our solution employs a balanced transformer design to solve all these power issues naturally and elegantly. Mains AC noise is reduced by the isolating nature of the transformer, enhanced by the balanced design, which increases the common mode noise rejection. At the same, the balanced design elegantly places its output’s live and neutral voltage at equal and opposite potential to the earth. Thus the earth now becomes a true null point and equipment powered with it will contribute very little leakage current and noise to the Eart, from their power supply sources. As mentioned earlier, safety earth and system ground are now inter-related, which also means less system ground pollution from the power supply side. Thus the balanced winding nature of the transformer is the key.

Power Delivery

In traditional non-balanced power delivery, noise from the equipment and mains leak to earth, polluting every chain in the system. In PLiXiR Balanced delivery, noise from live and neutral are out of phase to each other and cancels off at the earth point.

Transformer

It is not easy to wind a truly balanced power transformer, however. PLiXiR are delighted to work with Noratel, the premier audio transformer manufacturer. Besides being truly bifilar and balanced in design across their whole range and models, Noratel’s transformers also have unique design features which enhance noise rejection and current delivery into load, to gain better dynamics and transient attack.

PLiXiR spec their design to only have one set of winding per transformer. They do not cater for multi-voltages in one transformer. Often this method is used to save cost so that one can use a single model for all variants and thus enjoy greater economy of scale. However, this method of design unnecessarily complicates the transformer and introduces noise to the system. Their spec is, thus, performance first.
