DMB2600 is designed to bring life to even the most demanding and difficult to drive speakers . With Chassis being the only common thing between them, each channel drives 200W at 8ohms and 400W at 4ohms & 800W at 2.5Ohms. The doubling of power as the impedance drops is the testamanet to the robust power supply supporting the amplifiers .It comes with no compromise and very high performance power supply and heatsink to ensure long term reliability(Easily drives likes of ATC, Sonus faber , USher)
