The Advance Paris A-i130 NOVA pairs the warmth of ECC81 tube preamplification with the control and power of Class AB amplification. Its tube stage adds harmonic richness, depth, and a more tangible presence to music, while a 380 VA toroidal transformer supports dynamic performance and control over demanding speakers. A 4-channel ADAU1452 DSP and ESS9017S DAC in Quad mode help maintain precision throughout the signal path, from source to speaker.
