The New Simply 845 ranks at the top of Unison Research’s line of integrated tube amplifiers, second only to the historic ABSOLUTE 845. The SIMPLY 845, like the ABSOLUTE 845, also employs the famous 845 direct-heated triodes, tubes well known for remarkable durability and extraordinary sonic qualities.
The great advantage of integrated amplifiers is the incorporation in a single chassis of the preamplifier and the power amplifier. This makes it possible to eliminate the need for high-cost interconnect cables that are never truly neutral to sound reproduction. It should be noted that in the renewed production of the Simply 845 its size has been reduced by bringing all input and output connectors, strictly gold-plated and of a new type, to the rear of the amplifier.
