Feature

●Compact Yet Powerful: The V3 mini power amplifier combines a minimalist design with exceptional performance. With a power output of up to 600W, it can effortlessly drive 2-8Ω speakers, delivering impressive sound quality. Its compact size makes it suitable for various applications, from bookshelves and desktop setups to home theaters.
●Audiophile-Grade Components: It features the TPA3255 high-end digital class D amp chip and utilizes premium Japanese NCC, ELNA, and German WIMA capacitors, and Japanese Sumida inductors for exceptional audio quality. With a SINAD rating of up to 88dB, an SNR of up to 110dB, and a low noise floor of only 140uV, it delivers exceptional clarity and low distortion.
●Innovative Cooling: The V3 stands out with its groundbreaking heat dissipation design. Equipped with vents on the casings top and bottom, and a whole-body heatsink design, it efficiently dissipates heat, preventing damage to components and ensuring optimal performance.
●Scalable and Fun: Tailor your sound experience by swapping the stock NE5532 op-amps. V3 is compatible with a variety of 8-pin dual op-amps like Sparkos SS3602, MUSES02, OPA2604, OPA2134PA, OP249, AD827, RM4559, LM4562, LME49720HA, etc.
●Worry-Free: Enjoy peace of mind with the V3 stereo amplifier. It comes with a 24-month warranty, ensuring reliable performance and customer satisfaction. Note: The "Pre-out" level is NOT controlled by the volume control as the V3 is not an integrated amplifier, so the sound is NOT adjustable when you are connected to the "Pre-out".
