Hello edwincruz! Look into the Starke AD4.320. It's a four channel class D amp as good as the Purifi modules used in the NAD33 and now the M298 that are getting rave reviews. I have two Purifi EVAL1 packages (two power amp modules with a Purifi front end to make a stereo power amp - no power supply and no cabinet) and three of the Starke amp. running an 11 channel system (two 4 way stereo front speakers + 2 rears + front in a 5.0 system). The Starkes are bridgable to give you a stereo power amp with 320 wpc into 8 ohms. All forms of distortion are extremely low. The Starkes are complete amps, plug & play ready to go, balance and unbalanced inputs. Priced very reasonably, these amps are unbeatable. I have four other systems in the house (I love building loudspeaker systems) and am planning on putting Starkes into all of them. I learned about them in summer of 2019 and got the Purifi EVAL1s by 2020 and compared them directly to the Starkes. The differences are so slight as to be almost questionable. If anything the trebles are very slightly smoother with the Starkes. The switching is 50 Khz higher than the Purifi units.
