      Mass Kobo 394 II

      Musictec really understands audiophiles. I have several experiences where I describe in detail the type of sound I am looking for and the price range and they match me up.

      Every single time- they hit it on the nose. The key, they say,- is for the purchaser to give as detailed a description as possible so that they can properly advise. In most cases there was back and fort with multiple questions and answers and clarifications to make sure I was going to get the sound I was looking for.

      This headphone amplifier purchase went through this same rigorous process- and it is exactly what I wanted. The sonics are stunning. Transparent, fast, detailed, full bodied sound output with superrior control of the headphone drivers. I am so so happy. This amplifier IMHO clearly surpasses above the Oor/Hypsos, CFA-3, Audio-gd Master 9, and Bakoon 23R just to name a few amplifiers I have tried; and yet it is tiny, and light.

      Highly recommended amplifier and highly recommended dealer...
