These amplifiers are not DIGITAL!

Class D is NOT digital.

Those who are simply just making noise about Class D, just try to have a listen to Leema Acoustics Elements AMP with just 56Watts per channel with anything above (TRUE) 88db speakers and then you will understand you no longer needs that Class A or AB heater anymore on your room.

Class D is not digital! Where did you go to school? Class D is pulse width modulated.

Tear down & no demo! 6 sec sound blast would suffice!? Don't trigger copyright police...

I have the Behringer A800 class D and it sounds like no other amp so clear so powerful there is no other class that can come close to that awesome clear sound

Nice review and I agree, Class D nowadays are fantastic amplifiers with amazing efficiency. If you want to experience it, try an ICE amplifier unit with built in switching power supply. For just 100 euro you can buys this with 250 watts output and really great quality

Your multimeter isn't going to tell you much - the switching frequency of these amps is up in the range of 500kHz. You need a really good audio analyzer to see what these amps are doing.

Audiophile here. Class D can be great depending on the design. Those old recievers are nice for a nostalgia system for non critical listening.

From fixing crappy tape decks from the 90s to a purifi amp. At least i know your on the same planet as me now.

There’s a one man show in Ohio called Buckeye Amps run by a guy named Dylan. He assembles Class D amplifiers for sale. He has Purifi options in a higher power monoblock version and then also 2 and 3-channel versions using the same modules as the VTV in this video. He also offers Hypex amps using the NC252 and NC502 modules in 2, 4, 6 and 8-channel configurations.

I have a Class D AVR (Pioneer) and it drives up to 175W / channel in stereo. Sounds super crisp and clear provided you feed it a good signal!

I recently bought one of the Fosi Audio TB10D amps (The updated version) and it changed my opinion on class D amps. It seemed to have clean power output at the volume levels I normally listen to and plenty of "punch" and that was listening to a Rush CD at genre appropriate levels through a pair of Infinity bookshelf speakers. Not bad for around $80 and it didn't get warm. Interesting that the Purify amp switching power supply was twice the size of both amp modules.

I love the power and audio fidelity of these VTV amplifiers. I just wish they would put a couple VU meters in the front. What can I say, I'm a sucker for the old school amp look.

Crazy to think that the toroidal transformer on my parasound a21 weighs like 2.5 complete amps. Sure can appreciate the electricity savings you get with an Amp like this compared to a class a ab amp.

Purfi is another level, but I bought a crown xls drive cover to drive my diy subwoofer and I wanted to try it in stereo with my diy speakers and I have to tell you it sounds really good, very clear no coloration. I have some really nice speakers and they can handle a lot of power and this crown can deliver with no distortion and little heat. I'm thinking about building a class d kit or maybe get a ice amp off parts Express and make my own case

Wow amazing amplifier. Like that it's so light weight compared to the dinosaur amps that weigh tons.

I believe in you mr.12 volt that digital amp is good sounding and efficient ...i try it with a cheap module from china for my diy amp and even it was cheap i was very impressed for its clarity and efficiency compare to mid pricy class ab amp...

the little block of red caps are the filter caps the electrolytic capacitors and the 2 little inducters are on the power rails.

good its got a use for it
