The popularity of the Masterclass series has resulted in over seventeen years of continuous production. Offering an excellent price/performance ratio it is easy to see why it remains so successful. With an abundance of headroom, the MPA-4 mono power amplifiers deal easily with heavy complex music, allowing the low level detail to be heard clearly and accurately. Boasting a fully balanced circuit design, it can be the engine room of a fully balanced hi fi system.
