Those Crown amps are noisy and don't even come close to the low distortion of a Purifi design. I heard the Crown amps JBL uses in Synthesis and the fan noise was unbearable IF you have the equipment in an acoustically controlled room. I could hear the fans from 10ft away during quiet passages.

I don’t recall seeing a review, but now that you mention it, Ice is supposed to have some new modules bordering on the Hypex and Purifi standards. Pascal modules are supposed to be very good too, but harder to come by.

An amp in a box in a sub could be a heat issue, plus potentially the vibrations I suppose, other than simply price point. I use Crown XLS amps for my diy subs. Otoh the warranty replacement amp I got for my Epik from Epik before they shut down is still doing fine some 10 years down the road.

I use them for Mains, Center and Surrounds. I will buy more. Just look at the reviews on ASR. Hypex and Purifi Amp Modules own many of the top slots when it comes to their measurements. Yes, they can deliver in all the departments that you would expect a SOTA Amp to deliver in. Upon switching...

That one will deliver 200 watts to each output all channels driven. Because of the auto transformer the power is the same four or eight ohm load.

As you know, heat is the major cause of circuit failures. Most of the listed JBL AVRs are sold out but AFAIK, there has not been info out about failure of those AVRs so far, and I presume that Harman released more than a few of those AVRs.

I think the issue (1-2 ohm class-D) was that many people were not aware/seen those ohm measurements. And now that they can see those 2-ohm measurements, they can still say, “Okay, so class-D can handle 2-ohms, but where’s the actual 1-ohm measurements?” :D Does 1-ohm matter? Does 100dB SINAD...

Sorry if you have been over this 100 times as I haven't seen all the posts, but know you had the outlaws and now have the class D, so any differences worth noting? Or just smaller, cooler and easier to maneuver?

First of all, I must edit my post because it seemed misleading. I meant to say it is a sad truth that many people still think/say/believe class D sounds better than D, all else being equal, while if they don't know what class the amp they are listening to, with that bias removed, the two...

...phase, frequency vs. phase in degrees (dotted black line). John Atkinson of Stereophile said this: I suggest a relatively inexpensive Class D 2-channel amp from Buckeye Amps. Either one of these: Hypex NC502MP 2-Channel Higher power at $695: 450 watts @ 2 ohm 500 watts @ 4 ohm 350 watts...

I wonder if there are any class D amps that use linear power supplies for that reason? It seems logical to use a switching power supply with a class D amp that uses pulse width modulation. That would yield very good efficiency, but as you mentioned, switching supplies have their limits and...

I run my AVM70 with ATI Class D and Parasound, I can't tell the difference sonically and the ATI is dead quiet and does not get very hot. Doesn't matter which you use.

You have an excellent amp now....why would you change for another?

...the analog, and the analog needs to be split into two boxes, one for high level and one for low level...and I am not sure what to say about class D designs that mix both analog and digital to bring us clean analog sound? I am highly suspect there, but will probably buy class D eventually due...

Buckeye has a few class D 8 channel amps that are in your ballpark or well over per channel. Outlaw's 7 channel unit falls short but the monoblocks as mentioned would work. Monoprice's 7 channel: https://www.monoprice.com/product?p_id=14566 There's also stuff like this...

I took a look at those QSC amps, Gobs of power! Just a note, was just poking fun at Class D Amp power supply. They've come a long way Class D amps. Your absolutely correct, can't kill them Class D amps. A friend of mine uses Crown amps with his professional D J setup. They sit in his U haul like...

...amp (Design) one would stuff inside of speaker. Considering Longevity, reliability comes to mind though. With All of the great Advances in class D technology. Out side of Class D amps that Professional DJ use. I won't name any brands or manufacturers of commercial. Class D amps. Not here to...

...there is some sort of thermal protection built in which limits the output power. And again, for the JBL MA710, the formula looks like this: Class D: 0.125*110 = 13.75 watts / .80 (eff) = 17.19 watts x 7 = 120.32 watts So why did JBL mark the this as a 500 MAX watt device? Does this number...

You have some Serious wattage there! How'd you Integrated those into your system? I mean 1/4 jacks, what did you use or ran for speaker cables? I went back and took a longer look at those amps. Yeah I only saw two of those and they were in a theater. Brother of mine worked as a projectionist.

...type/tricks all of my neutral speakers and good recordings actually are. They essentially have the capability to be audibly flawless depending almost entirely on recording quality, once all the known standard basics are implemented. Even one of the recent $100 budget class D amps makes them...
