The Quintet is the much less expensive version of the Power Plant Premier. The main difference between the two is the AC regeneration feature found on the Premier and the price. Other than that, the Quintet offers the same filtration process, surge and spike protection found the Premier. The ten outlets on it are grouped into five pairs that are isolated from each other so there is zero impact of one pair of outlet affecting another. Also, the Nano Crystalline Filter Technology used on board is not power limiting so you can plug your power amp to any outlet. We tried a power amp plugged into the Quintet and to a wall outlet and the Quintet did help lower the noise floor somewhat to allow a bit more music to flow through. Add a solid build quality and for under $350 now, this is a steal.
Cosmetically, the unit looks good. Minor scuff marks here and there but nothing major. We don’t have the original box but will securely pack it for safe shipping. AC cord included.
