Class 'D' amplifiers - D-sonic

This video shares how a Class 'D' amplifier works. It covers the strengths and weak points. Featuring a pair of 600W into 8 Ohm mono blocks from D-Sonic.

Another great vid. I've had a good many class A and some mighty powerful class A B amps in my time and all of them ran hot, but at present I'm using a couple of Primare A34.2 class D amps in bridged mode delivering 550w into 8 Ohms each and the music sounds truly magnificent.

I am from the Philippines and I can't help but watch in awe at your great single driver per channel Sibelius speakers. Thank you ❤️ for the nice explanation.

I think a good class D amplifier can compete with anything nowadays and Bruno Putzeys designs seem to be among the very best.

Thanks to Zero Fidelity for pointing me to your channel. Phenomenal presentations and I'm in love with your speakers without having heard them...sigh.

I've had a D-Sonic M3a-1200S for my Legacy Focus SE mains for a couple of years now and can second everything you've said here. I'm now considering a mono block for my Marquis XD center channel.

Just subscribed, a balance between technical and ordinary joe audiophile sensibilities. Bravo

I think even the average class D ICEpower module sounds good nowadays.
Nice dynamics, good slew rate/transient response.
Class D used to be inferior to A or AB, but a lot has changed in the past two decades.

I have had a D-Sonic M3a 400wpc stereo amplifier for several years now, and it is an amazing amp. I routinely tell people who ask about it: If I had a budget of $100, 000 to buy another amplifier, I would NOT KNOW FOR CERTAIN what amp I would buy that I would like better than my D-SONIC. I have compared D-SONIC amps to amps well into the 5 figures (over $10k+, some even over $50k), and I like the D-SONIC better. The value of D-SONIC amps is through the roof. Even the smallest one (the one I own) will drive well just about any consumer loudspeaker on the market (at 400 wpc into 8 ohms and 800 wpc into 4 ohms).

I honestly love a good class D amplifier with a high end digital signal processor pre-amp which gets filtered through a good set of tubes before the class D. Whenever I run A or A/B amps there is always a somewhat annoying "pink noise" I guess if you listen closely during quiet parts of music etc. I don't get that with D class... Either I hear what is being produced or I hear nothing and that kind of "clean feel" is very much appreciated!

Great information. I'm currently using Dsonic M3000s for my Maggies 1.7s and it sounds wonderful and still delicate for my small stable of bookshelf speakers. The grip on the speaker is Ironclad. From what I understand the design has been upgraded. In the near future I will be taking it in personally because I live in Houston to have my unit upgraded with the latest technology. I also will ask him if he could add a gain knob like Parasound. This will help take some of the aggressiveness off the small speakers. It's delicate but you still have to be mindful. I think the gain would make it more forgiving.

Thanks for a really relatable explanation of class-D. It seems to be a good approach to maintaining signal fidelity. It’s harder to audition equipment now, there are fewer retailers here in London. There seem to be more class-D options now as it becomes more mainstream so I will try to find some to audition.

Just discover your Chanel . Amazing work .

These are great amp - i enjoy for couple of months the M3a-6100-7 in my HT and love it! Even made review on my channel! Thanks for this review also - the more people know about these great products, the better!

[jeremylister]

Nice vid.
As a PSU engineer of many years, do the 600W mono blocks have pfc?
Not sure of the regs on audio equipment!

[kinggodzilla]

Soundwise, it is advisable to pick a Class-D amp that uses a linear power supply and not a switching power supply instead.

[bphilbac]

Again, great info. I just subscribed.

I use Mola Mola Kaluga's I think you will like their performance a little better then these and they are 400 watts @ 8ohms and easier to live with. Just use a good aftermarket power cable with good connectors and good copper not the little evil cheap black 14 AWG crappy one it comes with. The capicitors a lone in Mola Mola cost more than the Hypex module and they use a proprietary power supply as well they make in house. It would be interesting to compare them. I would also think about using a good preamp from Mola Mola or an Audionet Stern. The Stern is the finest preamp I have ever heard, I use a Lampizator Baltic DAC with a built in active tube preamp. My speakers are YG Acoustics Carmel 2's.

Untill now I have never heard a class D amplifier sound any good. Yesterday I heard a 30 watt SET amplifier of Voxativ. That blew me away. Technology of the thirties of the previous age is still King.

Whilst you can extract a very good performance from a D Class amp with a lot less power consumption due to its high efficiency, a high end vacuum tube amplifier can give you a sublime listening experience and allow you to cook an omelette on top of the amp at the same time.

Interesting. But i saw "28'Hz Lo-Pass filter" was written on the rear! It should be Hi-Pass filter at 28'Hz if it is a low-frequency sub-sonic filter. (& it's far too low a f' if it really is a "28'Hz Low-Pass Filter" useful for a deep sub-woofer amp) Surely a mistake print. The fairly new Class D amps using Gallium Nitride transistors (or is it Gallium Arsnide? ..1 or the other) instead of the normal silicon transistors, I've noticed they are unaminously suprising some good (imo) Youtube amplifier reviewers who previously didn't like all the qualities of all their previously reviewed (silicon-based) Class-D amps, yet are all being very pleasantly surprised & 2or 3 near shocked by the new Gallium-x transistor switching amps. Ive no idea what type these are. Obviously very good nonetheless
