So you have finally invested in that VPI turntable, great preamps, some drool-worthy speakers et al, and are all set to sit back and relish Greta Van Fleet at their best, a touch of the modern with many a dash of Led Zep and Robert Plant, if you will. But wait just yet. For the enemy is all around you.

All around us, electronics device of various sorts and loads emits electrical noise picked up and transmitted through electrical circuits in the area where your audio system is installed. Power line noise pollution, a noise floor being formed within the electrical environment of your home or studio is one that one can nay escape. For an audiophile, this is where a device like Keces Audio’s BP-1200 1200VA Balanced Isolation Power Conditioner plays a crucial part in ensuring that the output of your hi-end audio set up stays true to the dynamism and vibrancy of its source material.

There are three variants in the Keces BP Series of power conditioners, the BP-600, BP-1200 and BP-2400, ranked in terms of the maximum power they can supply. Meaning a device like the BP-600 can supply a maximum of 600 VA, powering headphone-based systems, and so on.

Key to the BP-1200’s appeal lies in its high precision winding toroidal transformer. The strengths of a toroidal transformer, of course lies in its efficiency, which extends to far less heat dissipation and more compact sizes. With 90% electrical efficiencies, the key aspect here is the core, a continuous strip of grain oriented silicon steel which ensures that all grains are in the magnetic direction.

A second easy highlight that sets the BP-1200 apart is the fact that toroidal transformers are acoustically far quieter than EI transformers. The windings tightly envelope the entire core, effectively reducing magnetostriction – the main source of the familiar mechanical hum found in standard vertically laminated EI transformers. Again, toroidal transformers radiate about 1/10 the magnetic field of EI transformers because of the inherent efficiency and unique construction, thus eliminating the need for special shielding.

Once plugged in, the BP-1200 has another distinctive feature, as it stays clear of the typical shunt-mode surge suppression circuits generically used. Instead, excessive surges more than 2V above peak line voltage are absorbed, so that the ground is not affected, lessening the potential for contamination of noise output.

By isolating the transfer of electrical power from the main power source, the BP-1200 blocks electrical noise and interference that degrades performance and provides increased dynamic capability to dramatically improve the overall system performance.

The end result with the Keces Audio BP-1200? A far more dynamic soundstage, more realistic bass response and a wider harmonic range.

The Keces Audio BP-1200 Balanced Isolation Power Conditioner retails at $999
