M4+ Amplifier with built-in DSP
The M4+ can be considered as the little brother of the M6 model as both models share the same very compact chassis. The only difference is the M4+ comes in with 4 channels of amplification, but still offering more power per channel than its big brother. The M4+ features 4 x 100/135 watts at 4/2 Ohms and is bridgeable to 2 x 270 watts at 4 Ohms. The centerpiece is the high-end dual 32 bit 330 MIPS DSP processors from Texas Instruments which are controllable via the PC software or the new MUSWAY App for your smartphone or tablet.

DSP amps are the way to go! Love the difference of sound when DSP is activated. Not really familiar with the brand before but it says its from Europe and its expensive as hell so I think the quality is up there too with the top brands.
