With the recent huge up swing in the interest in vinyl records one company is introducing a product that can give you that sweet vintage analog sound to your current digital library of tunes on your existing mobile phone or tablet. The product is Leo a portable headphone amplifier that emulates the warm tone of vintage audio equipment. You simply connect Leo to your phone and favorite headphones to experience the sound that vinyl lovers have been raving about. Leo is constructed with a rugged extruded aluminum body, CNC carved aluminum knobs, and precision laser cut faceplates. The company is offering faceplates in a choice of black acrylic, walnut veneer, or smooth black leather. The other day I got a chance to seat down and talk with company founder Jacob Balthazor.
