An example would be providing a signal to the Linkwitz Lx mini DIY two way speakers combined with a pair of subs, which will require 6 separate channels.

I have been procrastinating for a long time to build these as a retirement project, and initially thought I would need to combine something like 3 pairs of Topping D50s DACs with 3 pairs of stereo amps.
However, the DM7 combined with a Buckeye 6 channel amp, with say 2 x Hypex 252 modules for the tweeters and 4 x Hypex 502 modules for the woofers, would provide a simple and elegant solution and eliminate a lot of clutter. I have no excuses now.
Thanks again Amir for introducing us to such a large range of cost effective high performance gear. This site is exactly what our hobby needs.
