I can't stop laughing. Thanks a lot.Yep. I have seen craters left behind when a GaN FET goes ballistic.

It looks modest. But so do I. Put it inside a box labeled Tiffany & Co., or one labeled Heckler & Koch GmbH, or one labeled Hermes. Soon these amps will be so small that they'll fit into the box you get when you buy a Rolex. So is the significance of this product that high audio performance per our (ASR) standards can be attained using a Class D chip that is reasonably priced and available as opposed to the current class of high performance class D amp modules (ICEpower, Hypex, Purifi) that are more expensive and are significantly larger in size? Some of the functions done on the circuit board of the Hypex and Purify modules are done in the Class D chip thereby reducing the size of the implementation. Again, I assume chips like the Texas Instrument Class D chip(s) are developed for broader market use beyond the consumer audio products.
Thanks for testing this one !
I was wondering: you test output impedance for headphones amps but not for speakers amps.
Is there a reason?
I'm also using 86dB speakers, but I don't feel any power shortage. The power you normally supply to the Audience 42 is less than 10W even at high volumes. The reason amirm measures the characteristics of an amplifier at an output of 5W is that the power we normally use is that much.I have no experience in Amp matching. I wonder if the Topping PA5 have sufficient power to drive my good old Dynaudio Audience 42 well? It seems to be power hungry.
The Audience 42 has a sensitivity of 86dB, 4 ohms, 150 watts (long term power handling).
The Topping outputs 140W x 2 @ 4 ohms THD+N <10% or 140W x 2 @ 4 ohms THD+N <1%.
I am currently using an ancient Cayin 220ci, 100W+100W@ 8Ohms, no data for 4 ohms, and I am hoping to upgrade. Thanks!
TPA3255 amps with rated power of 70w at 8ohms and 140w at 4ohms will have no problem driving 86dB sensitive speakers. I routinely use on 82dB speakers and it is more than enough. You need a 50w amp to be able to hit peaks at normal household listening levels. Even 10w rms is quite loud on 85dB speaker.I have no experience in Amp matching.

No.Behringer ?
For my speakers, are there any other inegrated amp/ power amps I could also consider besides the Topping? I am not looking for expensive fancy machines that "magically transform" my sound, but ones that are honest and transparent. Thanks again!
I think you are better off starting a new thread and be more specific about what you need.For my speakers, are there any other inegrated amp/ power amps I could also consider besides the Topping?

Do you already have a good dac? Are sources all digital or some analog? Do you need a pre-amp/integrated? Listening room dimensions? And so on..
I am sure this way you will get a better answer.
(Not that the Yamahas above are not good recommendations)
Genuinely curious. Accepting, the PA5 is overpriced:Look, for USD$349 it's grossly overpriced. That's the bottom line. But ASR members will lap it up in droves because it came 2nd in the 1kHz SINAD race.
But I hope Topping sells tons of them, because then John Yang will get carte blanche and a decent budget to design and build a bunch of real amplifiers, instead of these little dinky Class D things. That's what I am looking forward to. The last time we had no-expense spared, purely engineering-driven amplifiers, was the late 1980s early 1990s.
Over and over ...What are some similar amps costing less?
What are some better amps costing the same (or less?)
Hegel h95 (2000 US $) has 63 watts of power into 4 ohms and mediocre performance as measured by Amir and the list goes on.Genuinely curious. Accepting, the PA5 is overpriced:

I read a comment about the Yamaha's WXA-50, but it's 50% pricier than the PA5 (at least in Canada: PA5 460$, WXA-50 700$)
Other typical amps like NAD C316BEE V2 costs (550$now 650$) and not sure how it compares.
Thanks for the clarification..! The only distortion in the audible range is below -90 up to 30 watts, the 1st harmonic of 15kHz is 30kHz, etc, so not particularly worrisome?In the distortion vs frequency plot, not the multitone one.

Hegel?It's killed already and buried.And wouldn't the amount of Filter Capacitance play a large role with dynamics as well. Can a Topping PA5 really compete with a similarly powered Hegel H95, Audiolab 6000A, NAD... I'm looking to get a PecanPi and power amplifier to replace my Integrated + Dac + PC combo. Was thinking Pa5 could do the trick for my Home system but I think I will be better off with a Hypex NC252MP with more headroom...
(speakers are 89 db, 120W, 4 ohm - Dual 6.5" + 1" Dome)
