NuForce Reference 9 v3 (Selling 3, will negotiate for $1200 for sale of each.)

NuForce describes the V3 circuit as having an improved feedback path and better control over a wider bandwidth. The V3 circuit has different power spec than the V2: 175 watts RMS into eight-Ohms as opposed to the V2's 190 watts. However, into four-Ohms the V3 has 335 watts of RMS power as compared to the V2's 300 watts. V3 has lower gain than V2 due to design optimization with the new feedback control system. NuForce notes that the lower gain allows the preamplifier's volume control to be run at higher level which produces better sound quality with many of the preamplifiers on the market today.

The sound.The music lover will experience these developments in terms of a clearer midrange, smoother highs, greater low-end weight, and an overall sweeter presentation within a better-defined soundstage. In practical terms, these pleasures translate to extended listening without a hint of ear-fatigue. Given the V2's critically acclaimed excellence, V3's superiority stands as astonishing accomplishment. The Ref 9V3 SE, whichremains our flagship amp, offers features not found in our other models, such as a proprietary low ESR power capacitor bank, analogous to an automotive engine's turbo charger.
