I have only owned two 5-ch amps and both performed great.

Soundstream Reference (603 maybe?) that was stolen years ago.

Currently in my beater car:

USAmps 5600x with the extra input. It has modest output (75x4, 250x1) but sounds great so far.

The amp I owned the longest was a 3-ch "cheater" amp: Xtant 3150c.
It had only 3 amplified chanels but had two additional channels shared from the first two zobelly corrected. It sounded great, and I loved the plug-in modules you could customize it with. Unfortunately, she died not too long ago which prompted the USAmps purchase.

How about the upcoming Zed Audio LEVIATHAN? 100w x 4 + 200W x 2!

Honfatboy specifically asked for a 5-ch amp so I left this one out. Though I guess you could bridge the sub channels...

Hopefully, I will have one of these when released just to power my 3-way front stage.

Thanks for the input. The mac would be my choice, but too much $.

Well, if you think the Mac is too pricy then you will not like Zed Audio's Leviathan. When released it should be priced around $1000-$1100.
