Azur 640P Phono pre-amplifier

"The 640P delivers brilliant sound for the cash playing Bruce Springsteen’s Born To Run, impressing across the board. It makes the most of vinyl’s inherently superior timing, integrating instruments seamlessly while leaving each one secure and rigidly focused on the stage. Tempos cruise effortlessly, bass notes start and stop with straight-edged alacrity, and there’s intimacy and emotional weight to voices."
