Ref 8.5 V2 and Ref 9 V2 are identical except power supply. Available in black , silver and gold (limited availability)

Ref 9 V2SE utilizes an improved power capacitor board with proprietary Nuforce low ESR capacitor matrix and high performance capacitors. WBT NextGen RCA comes standard with SE. Available in black , silver or rose copper color .

The Ref 9 V2SE  adds refinement and delicacy to the already excellent-sounding Ref 9 V2.   The tonal balance remains unaltered, and when used in less than the most revealing and transparent systems, the advantages of the SE may not be fully realized.

As excellent as the Ref 9 V2 is, the Ref 9 V2 SE takes the strengths of the Ref 9 V2 to an even higher level. These include:

• Even sweeter highs, without any compromise in frequency extension.
• An even smoother and more palpable midrange, while preserving the natural harmonic structure that the Ref 9 V2 is famous for. The Ref 9 V2 SE is one of the few amplifiers in the world that do not impart its own signature on the music.  This results in a more natural and more relaxed presentation.
• The bass remains a huge strength of the amp.   The Ref 9 V2 SE has same tightness and texture of the standard  Ref 9 V2, but with a little more weight.
• The stage is more coherent and deeper.
