Sonance amps are essentially high value, high quality amps at very reasonable prices. They are not going to replace your McIntosh, Levinson or Krell amps anytime soon but if you want something really decent and don’t cost you a whole lot of money, they should be up on your list of considerations. The amp can be used as a 12-channel amp that puts out 30W per channel in 8 ohms or 45W per channel in 4 ohms. The 12 channels can be bridged into 6 channels to bring about an increase in power output to 60W per channel. So its total power output of 360W can be broken down as 12x30W or 6x60W when bridged. In most systems, this is more than adequate power unless you are driving very current hungry speakers.
Cosmetically, the unit is in good shape. Minor scuff marks and light scratches here and there from use but nothing major. The amp is pretty hefty (40lbs) and will be securely packed for safe shipping. Manual is available online.
