First of all I'm not a basshead & I have 2 earphones & 1 headphone. This review is based on those accessories.   Things I used :   Tablet & Computer for source (Both having average/below average DAC I presume) Headphones : Sennheiser HD 449,Sennheiser CX 180 Street II & Sony MDR XB70-AP   Review :   Build : One word,pretty amazing. It has lightweight brushed metal covered body without feeling cheap,& it's sleek & sturdy. Every knob is carefully built & easy to access,especially the volume knob is very well...
