I believe Rythmik also use Class H amps in some of their models that have 600W RMS but the top end HX series are (Hypex module) based with either 800W/900W RMS but I suppose that isn't a very good comparison as Rythmik utilise their highly regarded direct servo-based amp technology compared to...

I played with some Denon settings got my sound close to the Arcam, the Denon got HOT... I could fry eggs on it. That is probably why it burned out earlier. I am getting an exrurnal amp.

I got my Crowns used from a pro-audio marketplace... they were abused for a couple of years, then I bought them... 2x XLS2500 for US$250 each - they have been running flawlessly in my system for about 15 years now. Good quality pro-audio gear can be a recipe for long term peace of mind!

Yeah those older designed class AB amps on subs just seemed to last forever back in the day

Yeah most people don’t even know JBL AVRs exist. I know more about AVR than the average consumer, and I didn’t even know JBL AVRs existed. :D Like they say - only time will tell all - if these class-D AVRs are any more or less reliable than other AVRs.

...to eliminate the doubt that may be a more capable amp can do those towers justice. Some better choice would be the Hypex or Purifi based class D amps such as the following: Apollon Hypex NCOREx NCx500 Multichannel Amplifier (3-5 Channel) | Apollon Audio Hypex Purifi Premium Amplifiers...

Can't find any useful details on those speakers, except that those early class D amps in those speakers blew up at an alarming rate. Details of the speakers seem to have dropped off the edge of the Earth. However from what I remember the arrangement was similar to the Def-Tech speakers and you...

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.

28 Years Later 4K ATMOS Streaming. SPOILER ALERT. PQ. Shot and mastered in 4K digital. I think the picture looks good for most parts. Really no complaints. SQ. Some good ATMOS Overhead sound effects. Some really good bass. Overall pretty good. Writing. This is where I have a problem with...

...pieces, just no need for a 100+ pound stereo amp and definitely no need for a 160 pound 1.2kw anp in a day were 30 pounds of 1kw heatsinked class D is state of the art. I imagine anyone could design a beautiful faceplate if it boiled down to aesthetics. With the difference in cost, the sky...

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 would like to add a balanced DAC to my chain. I have a Hypex based NCore class D amp which accepts both RCA and balanced XLR inputs. The source is a WiiM Pro streamer streaming HiRes audio from internet services. After some research, I found two very well regarded balanced DACs, the Fosi Audio...

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...
