Lyele Audio ECC82 Vacuum Tube Preamp Hifi Sound Preamplifier NE5532 Treble Midrange Bass Adjustment High End Sound Ampli

Product description:

• This product adopts the technology-leading "absolute linear audio amplification" circuit, uses nonlinear components to amplify, and then distorts the distorted signal again. Excellent, emotionally charged music

• Reasonable power supply design, the power supply part is installed in an independent section, using a ring pure copper power transformer to reduce electromagnetic interference and extremely low noise

• ECC83 and ECC82 are used for amplification, 6Z4 is used for rectification, and the tone part uses the classic dual op-amp NE5532

• Using German ERO fever-grade capacitors as coupling capacitors, using Philips Japan ELAN electrolysis as filtering, good extension at both ends, excellent high and low frequency performance, deeper low frequency dive, flexible, thick and stable intermediate frequency, and slender and elegant high frequency
