I was reading on these boards and others for years how outboard amps are a must. I couldn't understand why because my system was just dandy loud enough with my receiver. I could keep turning my receiver up and up and up until it was hard on the ears due to the harsh highs. I thought the harsh highs represented the amp limit.

Was I ever wrong! I see now how my Onk and my mid-grade audiophile (?) Pioneer receivers differ by listening and also looking under both hoods. The Pioneer, right up to the point where it self-protects, allows for all the dynamics to come through. The Onk starts limiting those dynamics from a very low gain but rather than telling you it does by self-protecting, it soft-clips. You think you're getting all the original content but you're not. The big reason for the increased dynamic range of the Pioneer is 4x24,000uF caps in each power supply - there are two independent power supplies, one for each channel, each with its own toroidal transformer and cap bank. This is of course very similar to what Axiom does with its amps.

Now I know I need gobs of clean, powerful amplification. While the Pioneer is great for what it is, 55W per channel and those large caps still doesn't cut it for my M5 living room system. I also need amplification for my M100, 160 and QS10 in my main space.

What do you all recommend for 2 channel and 5 channel amplification?

Popular at the moment is the new Monolith line from monoprice. Comparable to Outlaw, Emotiva etc. Rave reviews all around

No Idea how those would compare to the ADA line up. In terms of real power disclosure, though they seem realistic 200 Watts common rated.

Thanks. I'm very interested in dynamic (transient) specs...not often given.

As I've said to Ian in the past, I need a 20W amp with 8,000W dynamic capability. smile

I am looking at the Monilith too. Heard nothing but good things except for it can get a little warm and just make sure there is proper ventilation.

According to AudioHolics testing, it actually pushes more than what it is rated.

Continuous 2channel
221watts at 1% 212watts at .1% into 8ohm
356watts at 1% 335watts at .1% into 4ohm

Dynamic 2channel
284watts at 1% into 8ohm
521watts at 1% into 4ohm

Distortion rated exceedingly low.

https://www.audioholics.com/amplifier-reviews/monoprice-monolith-7-channel-amplifier-review/3

Given the fact this is built in US by ATI and can be had for like $850 (2channel) during BlackFriday plus a 5yr warranty, it is a steal.

MonoPrice is changing the game with their Monolith series. Their subs, especially 15in, receive phenomal reviews for their price. I have dealt with MonoPrice for over 15years and their service has been exceptional when I’ve had any issues.

Either way, it is an exciting time to be an audiophile with what is available to us in regard to quality from various manufacturers at relatively low pricing. VERY Interested to see the Axiom active line and the future of home audio in general. The future of Wireless power would make active speaker placement a lot easier too :P. I can only imagine how my grandkids I don’t even have will be living in the future!

Don't really have much to add but I've heard the Monolith is very well rated. I added an Emotiva (Gen2) 5 channel a couple of years back which has served me flawlessly as well as a Monoprice "No Logo" 2 channel amp I purchased maybe 3-4 yrs ago. I don't believe Monoprice sells this particular amp anymore which is too bad. I took what I thought was a chance on a single unit, but in hindsight I wish I'd bought a couple more...235 watts per channel for $177! Adding outboard amps to my system really seemed to give the bottom end, I don't know, more weight?


Half of communication is listening. You can't listen with your mouth.

Less distortion

Another selection without as much power is NAD.50 watts I think. Have been scoping their 4 channel power Amp. for a while can be had for under a thousand new, think it's 4020 or 4010 model. Probably awesome for surround duties. Being typical power for those speakers.
My MRX720 pushes 60 for the rears which has no problem with my QS10s.

The NAD units have tested very well in dyno tests. They are typically conservatively rated. Sometimes by 50%.

They list dynamic power in their spec sheets as well as ordinary FTC. The new units are Hypex based. Pretty cool stuff.
