The Ref 9 V3SE utilizes an improved power capacitor board (Nuforce proprietary Sequential Linear Array design) featuring Nuforce’s proprietary low ESR capacitor matrix and high performance capacitors.

The Ref 9 V3SE adds refinement and delicacy to the already excellent-sounding Ref 9 V3. When used in less than the most revealing systems, the SE’s advantages may not be fully realized. As excellent as the Ref 9 V3 is, the Ref 9 V3SE takes its strengths to an even higher level. These include:

• Sweeter highs, without any compromise in frequency extension.
• A smoother and more palpable midrange, while preserving the natural harmonic structure for which the Ref 9 V3 is famous. The Ref 9 V3SE is one of the few amplifiers in the world that does not impart a signature on the music. This results in a more natural and relaxed presentation.
• The bass remains the amp’s huge strength. The Ref 9 V3SE has same tightness and texture of the standard Ref 9 V3, but with a little more weight.
• The stage is more coherent and deeper.

In summary, the SE’s sound is more neutral and liquid, with a more relaxed yet powerful soundstage presentation.
