Techincally need 7 channels of And the class D technology is much more sensitivity with RF/EMI than class A or class AB. - Compared to the class-A, distortion at low level is similar or lower, harmonic distribution less perfect, but since level is far below threshold of hearing, that does not matter. goryu Addicted to Fun and If you have the choice, which would you choose and why? Price not in consideration. Sunfire amps use Class D to control the rails of a Class AB output stage. Apart from that, many Class AB and H PA amps, and lots of Class AB HiFi amps from for example Denon, Parasound, Uher, Sony, Conclusions: The average consumer’s perception that with all things being equal a Class-AB amplifier is superior compared to a Class-D amplifier still remains and is strong to this day. Opinions: Hypex vs. new topology compared to class A or AB. This is very reason of biasing amps with higher currents like First watt and similar amps. Is there The Wolverine was cheaper - those Hypex's cost @ 400$ each. I've heard some sterile class D amps and some that The data says so. His Hypex and Purifi designs are much better than Tripath's. Joined Jan 7, 2020 Messages 1,159 Likes 1,516. I have been advised by a ASR peep that when clipping class D amps clip hard and sound horrible as compared to a class A/AB that clips and gradually the distortion increases. Stupid though, as you get the same power out of the slightly cheaper TPA 3251, which sounds just as nice. combined with the more typical class-D strengths, then Hypex is the best The 500 watt peak output @4ohm looks not much compared to a SVS SB2000 subwoofer that has 500w rms and 1150w peak output. End of 2007 I upgraded to UcD400HG, equipped with HxR regulators, the original PSU’s and trannies from Hypex; a friend made me a nice casework – now I was in heaven – a reason why the motivation to assemble the The Hypex ncore 125 and the 5125 sounded exactly the same, I cant hear any differense between them. If it matches the audio performance of a class A An AB with a SMPS might also end up with its rated and max power being quite close to each other - also the amount of capacitor reserve in the design will determine the short term peaks possible Look at Benchmark Hello, I've compared my Hypex NC400 DIY amps to my previous Pass Labs X250 head to head. Solder R7 & R8 jumpers to bypass the TO220 voltage regulators. Thread starter kovaga; Start date Jan 15, 2022; I listened to many class AB amplifiers and all the subjective differences for many years until I made some blinded sessions and all my perfect world was shattered.

To be more precise, why are the class A/AB amplifiers the only one considered as an "audiophile" choice of amplification when they measure worse compared to the nowadays class D (hypex, ICEpower) amplifiers in both S/N ratio, THD, and power. Let's say I'd take a $299 Emotiva Class AB Look at the value on the used market of the MC252, long out of production, vs two of these class D amps brand new. Anyone else done similar comparisons with Hypex, Purifi or top-shelf class D? L. That might indicate class B dot D or B cross D where a class AB amp provides precision next to class D providing the I compare my Azur 840 class AB to my NAD 3045 that is powering a pair of KEF LS50 in the office, and the former consumes 90w idle, while the later uses only 15w. mononoaware Addicted to Fun A friend who design high power class D amplifier, compared his amplifier with Hypex class D amplifier. I bet you would be hard pressed to hear a difference between those amps and Nilai Hypex Nilia vs NCX500 vs PURIFI Eigentakt Opinions? diyAudio Community diyAudio Store. A lot depends on implementation, so two amps using the same chip can be very $500 price difference, with the class AB 509X costing a hair more but putting out more power. So for example, is it really OK to run a speaker with max power rating of 150W with these hypex ncore amps rated for 500W? So is there a difference between these AB / Class D power ratings, and if there is, how to decide on which amp to buy? Vini darko Major Contributor. When it comes to cheap Chinese amps, it's hit-and-miss. Another thing to bear in mind that upgrades have occurred on many Class D designs. Purifi 1ET400A - Class AB vs Class D ampAUDIOPHONICS HPA-S400ET Power Amplifier Class D Stereo Purifi 1ET400 is a Class D stereo pow Class D is the future. Given the common bias against Class D in 2-channel audio, it would be interesting to see some comparisons between similarly priced Class AB and Class D power amps. But only with same settings. D-sonic, cherry and buckeye are mentioned here often as well. I have an AVR (class AB) for the center and front and a class D amp for the surround speakers. The most impressive differences between the Class D and AB are the sizes are much smaller and lighter and run much much cooler. Trinnov Altitude 16, Kaleidescape Terra Hypex NCx500 Class D Amplifier Review. In fact it is stated in the article on the fist post: "the new NCx500 OEM module features an on-board, high-end buffer stage combining Hypex' established HxR discrete regulators with carefully selected, high-grade components" Up to full power, a class-H design rated for X Watts will require less energy than a pure class AB design even though the intrinsic amplifier is no more efficient; you get the improvement by reducing the power rails. Class D has the least hiss of all (well, except Benchmark's THX class AB ). Reactions: yys310. Joined Mar 1, 2016 Messages 3,217 Likes 4,306 Location Amsterdam, The Netherlands. Hypex Ncore represents the very best in performance for Class D technology, which is why all the "high end" guys are adopting it. Because it is significantly smaller, lighter, and less expensive Buying Purifi/NCORE when you already have a decent Class-AB will likely lead to disappointment. For Class AB vs. Another option is to keep one Class AB amp for the compression driver and replace the other with Class D. So the distortion that this switching creates is at an even higher frequency, we cannot hear that! Indeed class D amps with switching PSUs miss a lot compared to Class AB amps with a linear PSU, and even more so wrt Class A amps: cost and the power bill. I think it is now state-of-the-art for amp design. Having . Class D will win (commercially) , OEM's can manufacture them for 1/4 the cost , 1/4 the weight and still charge $2000. Smooth detailed. So have Hypex nCore vs Class A amps. Hypex Ncore amplifiers excel in efficiency and Audiophile class AB vs Hypex N-core class D technologies . 5dB extra output is nothing to sneeze at if you have low sensitivity speakers. A more detailed view on the state of Class D is at the end of the review. Hypex UcD180HG HxR module is an older class D circuit solution which cannot compete in distortion parameters with Ncore or Purifi, however it has several very interesting features. Not the "Class-D" forum I'm surprised I haven't seen more discussion about the new Nalai DIY boards from Hypex which should be rolling out in March 2023. Big difference between hyping "300W x 2" as opposed to the actual output of 75W x 2 into 8ohms when run at 36V. People don’t realize how much more challenging Class D is compared to Class AB. Some like Devialet and the Hypex N Core based designs have gotten good reviews- but they're extremely expensive. I'm hoping to do a comparison on Class D based amplifiers soon, including: Tripath, Gainclone (LM3886), ICEPower, Class D Audio, BYOB, and a few others. Audiophiles who cherish the warmth Class D is definitely the way forward. Joined 2009. TDA729x are alternatives for varying power levels. They all sound good on their own way but there is a contrast difference. So in summary, in my system and based on my sonic presentation preferences the Class D amp was the winner between the common Class A/AB unit I compared it to. Smaller, lighter, more efficient, less expensive to purchase and run; and sounds just as good if I've compared my Hypex NC400 DIY amps to my previous Pass Labs X250 head to head. For laymen, it can seem less louder than a weaker amplifier with better input sensitivity. I do not have first hand experience with class D amps in listening tests. Purifi 1ET9040BA vs AGD GAN vs Class A/AB. If it's a lot more than a Class D amp I'll consider to invest in quality amps like the Hypex stuff. Forums. 1200W supply. After spending some time reading threads in diyaudio, audiosciencereview and asking in our local forum about what are the best class D modules I had to choose between Purifi, Hypex UcG, Hypex Ncore, ICEPower and a few others. A quad balanced 462 amplifier VS a class D Hypex nCore vs Class A amps. It’s about 200 watts at 8 ohms. Until Hypex NCore changed the game, Class D amplification was about compactness and electrical efficiency – but Hypex NCore also offers obvious superiority where clarity, resolution and outright musicality are concerned. 7i speakers. Tonality and overall resolution varies with implementation, so it cannot be generalized imo. vipersg; Sep 19, 2024; Stereo and Multichannel Amplifier Reviews; 2 Final Thoughts on the Buckeye Amps Hypex NCx500 Stereo Amplifier. The Chicago Crusher. Neurochrome Modulus amps come to mind. On high dynamic music like 1812 overture (telerac), when playing it loud. To put it crudely; there isn't much of an appreciable difference between 0. The Levinson sounds noticeably better dynamic than Class D , more life like presentation. Class D amp. I bought the NX200s (which incidentally are not Class-D but Class AB amplifiers so would satisfy the purists) connected them up using the Hypex switch mode power supply and set back to listen to really superb sound. 3V into 8R. AB has crossover distortion, after which the amp has virtually no distortion before clipping near the rail voltage. Many amps transition from Class A to AB at *some* output level. Almost certainly my source (Marantz AVR) has middling SINAD. I think the HypeX NC502MP is good enough for HT and a great price for 8 channels of it. Infact if you are assembling yourself than you can use better quality parts. Reactions: boXem, CDMC and andreasmaaan. Bleh. 90lbs when comparing our 8ch amplifier to a The Hypex Class D amps have generally been well regarded for their sound quality.

Doodski Grand Contributor. Holton. "Hypex [class-D modules] cannot drive it, the amps collapse, but this Brooklyn Amp does it with ease. Today, after some experiences (always with decent but "normal" speakers) and thanks to ASR I don PURIFI 1ET400A vs Hypex NCORE NC500. I would never recommend anyone looking to quickly DIY a great amp to go and Class D is cheap and mostly prebuilt compared to Class AB. The only amp I have that sounds better than my Nilai is a Class A SET with 2A3 tubes. Remember, as the power goes up, so does the S/N and there are multi KW class ABs Ricky Roma: I subscribe to the law of contrary public opinion If everyone thinks one thing, then I say, bet the other way Reactions: Alec Kinnear, mariano3113 and oldsysop. For finished DIY amplifier boards, Neurochrome has some very performant amplifiers. a class A (or class AB amp)? I noticed nothing what Class D is smaller, lighter and converts ~90% of the energy into sound (compared to ~30% with class A), so it doesn't heat up. I currently have a Plinius SA50 which you can switch between class A and class AB on the fly, sure class A sounds slightly better but it draws 600W constantly from the wall too. 700d. Purifi vs Hypex vs ICEPower. Speakers are Harbeth 30. The measurements of Class-D (Purifi) vs Class-A, Class-AB amps were similar to what has been shown elsewhere. Now the Purifi's reputation is already legendary for its technical specifications and measurements After making more than 5 different DIY amplifiers in class AB I decided to try class D. Class-D topologies finding their way into high-end audio is new compared to Class-A and Class-AB designs. With one A800 and one STD-400 I could test both to check the difference in sound quality. In my old car i used a JL Audio class d amp that also had 500w rms @ 2 ohm with a test tone @50hz. The only reason you would ever want to use a class D is if, for some reason, you had space or weight limitations, or for a subwoofer. I know there are many Buckeye has an 'auto' power setting. It is not blind test, just casual listening. Class AB open loop gain is only weakly dependent on power supply voltage. class ab on your scope. In fact, most of the rooms for that show was running a Hypex module of some description. While the this thread is about pre-amp stage of the Hypex N-core amps so anyone interested can chime in and contribute or ask, this is purely technically oriented thread so don't ask about amp sound or comparison between class D vs AB or DBT or what ever else OT already mentioned in other threads (including those closed down) I am not an engineer, and don't like to have to worry whether a "250wpc" Hypex Class-D amplifier is as powerful and will have as much headroom as the honestly-rated 140wpc class AB amp it will be replacing. 1) about the same time frame that got used about twice a year, died the first time its outputs got accidentally shorted through a slipped cliplead! I also had a cheap class D board (Chinese off-brand), died from failing electrolytic caps within 6 months use. I've heard plenty of other Class D amps like Lab Gruppen FP or IPD series, Nexo NxAmp, Powersofts, Synq, Crown. By Escksu August 14, 2023 in Stereo Amplifiers & Pre-Amps Share One of the downsides of high bias class A, AB etc is that the heat does age components more quickly, and capacitors in particular, and failure or degradation of supply or rail bypass caps While equipment, life, and living spaces can of course change in the future, long story short is that I'm confident that the power rating of the 400/500 Hypex and Purifi modules (and equivalent Class AB designs) is more than enough for my needs - and I'm happy to pay the small price premium for a Hypex 500-based amp over a 250-based amp even Vidar is class AB and Hypex/Purifi are class D. Once again, a very controversial topic: class D Class D has gotten really good now. I started with class D then switched to Rotel class AB. They have low input sensitivity. 7's to the much larger living room, after listening they aren't going back to where they were before, even if I have to spend a weekend putting acoustic damping tiles up I agree that for class D, TDA8932 is very good. LM1876 is fine as well for lower power levels. I did notice that the new NCx500 now has a buffer, as opposed to the former NC500 (and NC400) which were bufferless. I just switched from my 3000€ flagship integrated Amp (Denon PMA-2500NE, 25Kg, Class AB) to 2 litlle Monoblocs, NC250MP based, paired with my ADI-2 DAC. Share: The world is full of class AB amps to explore. So, I got a new class D amp (TPA3255) to replace my old AB amp, all in all I think it sounds much better than the AB amp, but I have one big gripe with it.

And the 252 takes a hit on value because of the notch. G. Class D is smaller, lighter and converts ~90% of the energy into sound (compared to ~30% with class A), so it doesn't heat up. It underscores the importance of high quality amplification in the chain However for a similar price and minor assembly (less interesting to me) the Hypex Niali 500 as well as purifi have good reviews and performance. IndianEars said: As you may know, a class AB amp driven closer to its max output is likely operating at in its lower THD range. Model 525 Model 201 Model 10 Model 6. I'm curious what the class D experts have to say about this. Currently listening to Onkyo vs Purifi on R3 - first proper volume-matched comparison I do, assuming these amps will be the most different from the set.
