Hi there. I have been using the muzishare x7 amplifier for a year now and I really like the way it works. Therefore, if you are looking for a quality amplifier at a good price, I advise you to purchase it. For my small studio, it fits perfectly, although we tried it with friends at larger studios and I can say that it is in no way inferior to more expensive counterparts. I was very pleased with my purchase, so I can definitely recommend this amplifier to you. Need your opinion..
