Sound quality at 100RMS x4 (4ohms) recommendations?

[Pataforce8 10+ year member]

Hey guys, I need a high aound-quality amp that does about 100RMS to 4 ohms to 4 channels. I'm trying to research as many brands as I can but I'm coming up with a lot of crap.

So far I'm considering the Sundown SAX100.4D, the AQ4X90, and an MB Quart Onyx amp. Which would be best for sound quality and are there any others I should consider?

Out of those, I would say the sundown, look into buying old school used equipment

The Sundown does have a nice crossover section.

+1 for old school. I have a 19 year-old Zed-built amp for my front components that is currently blowing my mind with the SQz.

I don't need any crossover work, I have that taken care of earlier in the audio path. I noticed that the AQ has a damping factor of about 250. From my understanding, damping factor is a ratio of ohms to ohms, so it shouldn't have a unit?

Regardless, is 250 relatively high? Any idea on the damping factor of the other two (I looked but couldn't find)?

My front stage will be run by a Us Amps 150x =] My sub will be run by by a Zapco Z300c2 =] Old school is the way to go!

The xover section on the sundown is nothing short of drop dead sexy =]

Damping factor is a useless marketing spec. For it to serve any semi-useful purpose, you would have to know what it is at your speaker terminals NOT the amplifier. Don't believe the hype on this one!

Good amp here //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

No! Haha not the headunit! I don't think the one I have does any x-overs...just 3 band EQ. But I have a 9 band EQ that does all the x-overs I want.
