I have a Melos Maestro (New model SHA Gold) and I enjoy the sound very much. I have had no problems with the unit and would recomend it to anybody. I have not heard the AI 3a or L1 to compare. If you buy a SHA Gold do a tube change to Amperex 7308, it is a nice upgrade. Sedond is correct Melos does still exist in Las Vegas and they are very helpful.
