Isotek Power Products

Isotek power products are designed to help get the most out of any HiFi or Audio Visual system. We still find it quite amazing as to how much difference paying careful attention to power makes to the overall sound.

Isotek power products have won numerous awards and have the ability to improve nearly every HiFi or A/V system.  At Douglas HiFi we have literally 100's of happy customers who didn't believe it until they tried it and heard for themselves.
