Top 5 Best Budget Class D Amplifier – Buying Guide And Reviews
Apollon Audio is a company specialised in hand building premium quality Class D amplifiers using only high end Class D modules and components. Tibor Marksel, the founder of Apollon Audio is a seasoned audio and mastering engineer with a trained ear and more than 15 years of experience in the recording industry. His attention to detail and perfectionism is present in every product that he makes. Throughout his career he had the chance to listen to numerous configurations of speakers and amplifiers, but he was never fully satisfied with what he heard.
This lead him on a quest to build an amplifier that would meet his demands for high power and dynamics, while at the same time have the record sound exactly how the mixing and mastering engineers have put it together in the studio, and enjoy that exact sound at home.
This all finaly became possible after implementing high end Class D modules and getting creative with Class A Op Amps. Apollon audio amplifiers that are based on the Hypex NC Class D modules use a custom built buffer board on the input stage. You are able to choose from various Op Amps that match your style and flavour.
This is what makes all the difference in the sound and enables the Hypex NC to work to its fullest potentialgiving you pleasure each and every time you play your favourite recording. Keeping your cables short aside from using high quality cables is a good way to preserve the audio signal in its full quality.
If you prefer this way of powering your speakers our Hypex based Class D monoblock amplifiers are the best fit for the job. The smallest stereo amplifier starts at 75W 8ohm per channel and the most powerfull amplifier packs remarkable W 8ohm. We only use proven Class D modules from Hypex that are the industry leaders in Class D development and sound quality, paired with our custom input buffer boards for thrilling musical enjoyment.
You have the option of choosing four, six or eight channel amplifiers that are built around the Hypex NCMP series modules that sound grandiose and will provide you with ecstatic sound wether enjoying a movie or listening to a live concert performance that was recorded in surroud technology.
Altough lightweight the amplifiers provide tremendeous power to your speakers. With Hypex NCMP modules driving the low and the midsection and the acclaimed Hypex NCHF feeding your tweeters you can expect mind-blowing sound reproduction with unbelieveable low and mid frequencies paired with startling high frequencies thanks to the NCHF module.
Just some of the testimonials we received in our email and found on the internet which tell us that we are on the right path. Very happy so far with my purchase. Thanks again! Everything you said about the amp is true.
Super accurate, super precise and fast. I rediscovered my NS10s. I will do a very good publicity for Apollon Audio. A fresh company from Austria… they know what they do and their amps sound phenomenal. The secret to more power and detail in your Audio setup. High End Class D modules used in our amplifiers give you all the power you need and more, while the sound is always clear, detailed and precise. Low frequencies are very present but controlled and the high frequencies are open, clear and glossy.
Many thanks S. I'm looking for audio components that are plug n play rather switching modules, although it would be quite an adventure to build a component using one of them.
Any suggestions? Thanks S. I haven't heard it personally but another poster mentioned it a while back. He went out and demo'd a bunch of equipment and ultimately settled on the i It sounds like Primare is at least worth listening too. Thanks, Bierfeldt. I'll check out the Primare. Yes, I'm looking for a power amp, 2 channels, although now that you mention it, multichannel would be of interest too.
At the moment I'm driving my Maggies with a Bryston 4BSST2 and I'm not unhappy with the combination, but for various reasons I might want to go smaller, cooler, and yes even more grunt than the Bryston, or at least find out what there is out there.
On multichannel Id also like to know what's out there that would enable a switch from my Integra integrated to separates without breaking my bad or my bank account! Many thanks for your interest. Best S. You need to listen to the Sunfire Cinema Grand. If you are unfamiliar, Sunfire was the company Bob Carver started after he left Carver corp back in the 90's.
There is a white paper that explains how the tracking downconverter works, but basically it is a class A amp that behaves like a class d.
This tracking down converter allow the amp to vary it's power consumption with it always remaining just above what it needs. As a result you get lighter amp that can deliver monstrous amounts of power and runs cool. Literally room temp no matter how hard you drive it.
There are 2 models, a 7 channel w unit and 7 channel w unit. Coincidentally, Sunfire offered 2 lines of cinema speakers, the HRs line which called for w and the Cinema Ribbon line which calls for w of power. The HRS line was recently discontinued.
Both amps are balanced and would pair nicely with a Marantz or Integra pre-pro. I have been flirting with the idea of getting the w model to replace my Marantz MM largely because I have the HRS line of speakers in my theatre and am taxing it just slightly. I currently have a Marantz pre-pro paired with the MM I am very cynical on the technology. I thought it deliver more power and sounded as good as a Marantz MM and, like I said before, I hear good things about Primare.
I just haven't heard a class D that can outperform entry level separates like that Marantz. Audio power amplifiers have different "classes" of operation.
Class D, which are also referred to as digital or switching amplifiers, are the newest class, and initially were used primarily in automotive and subwoofer applications. These first class D designs were not in the same league in terms of fidelity and specifications compared to the other classes of power amplifiers, especially when it came to higher frequencies, but that has changed with the most recent digital designs, but why?
The history of Class D amplifiers began in when the British scientist Alec Reeves invented the original design. The first commercial product was the Sinclair X, which in was rated at 20 watts output. But it wasn't until the 's that Class D amplifiers began to appear in more and more applications. Since the 's Class D designs have had almost forty years of refinement and development.
Since one of the more important aspects of journalism is knowing when you don't know something, and figuring out who to ask, I've gone to three manufacturers who concentrate primarily on Class D power amplifiers in their components three questions about current Class D designs What has changed in the design of digital or class D power amplifiers since their inception to make them into higher fidelity devices?
For my designs newer parts with an Increases in speed and voltage of their high power components, more creative modulator designs, better PCB layout techniques, and general experience with Class-D circuit design, better simulations, and a far better and more developed knowledge of how the circuit variables affect sound quality has made for a much better final result. We also have found ways to tweak our designs for better sound while affecting the specs slightly.
For example, our Cherry MEGA can do dB on the bench before tweaking, and dB after tweaking, which is still very low noise specification. What are the primary advantages of a current-gen class D design over older amplifier technologies? In general, Class-D designs have benefitted from better components, but better topologies have also been developed for better performance. The "old Class-D" was done with triangle wave generators and complex feedback networks.
There were so many compromises to achieve reliability and low cost. There are many more ways to make a Class-D amp now, and bench performance has improved greatly. The biggest differences have not only been in lower noise and distortion, but also bandwidth improvements. We design amps from scratch, down to the smallest component, so this doesn't apply to Cherry Amps.
We first consider the scope of the device. Is it a finished product, a board, a circuit, etc. Is the power supply external, internal, integrated, or is there something special about it? The overall topology is chosen based on the application. Half bridge, full bridge, balanced, single ended, DC or AC coupled, etc. Required audio performance, physical size, efficiency, and power level are all part of the decisions early in development.
Operating temperature may dictate what components are available and their limitations with respect to packaging and cost. That's phase one; deciding the basics, then comes the fun part One thing that attracted me to Class-D design is that quite often, despite valiant design efforts, prototyping shows significantly lower audio performance than predicted or targeted.
So, we tend to focus on circuit simulation during the next phase. Simulation, prototyping, and testing are repeated until a circuit schematic emerges. Sometimes the simulation part is considered complete while tweaking of the hardware continues. Sometimes prototyping requires PCB layout if it's not practical to build one-up hand wired boards. After the circuit performance is considered acceptable, a finalized board or boards design is next.
There are two basic types of testing -- design testing verification and production testing. Producing reliable, quality products is only possible with good production test coverage. Much of the above is what goes into any electronic product design. That combination creates unique thermal, EMI, impedance, speed, and cost concerns.
Some of our amps skew nearly V in only a few nanoseconds! Search form Search. Show Munich More Reports. Solid State Power Amp Reviews. The components I needed to choose for my first system were never in doubt: a turntable or record changer, an integrated amplifier, and a speaker. One of each, please, in those mono days. Digital has exploded the range of source options and loudspeaker options. Yet amplifiers have not changed much in how and what they do. That's a good question. Another is: Why should I write this review when, just seven years ago, I reviewed a pair of darTZeel monoblocks that look exactly like this new pair?

Peachtree nova 500 review
Hi Arch, happy ! Looking forward to your measurements although Amir's are a pretty good selling point. I'm currently running 2 relatively dated and hungry power amps by Quad and Hafler for my MCH setup, and Class D looks like a very interesting alternative. Might even pay for itself. Mitchco's project looked a bit daunting, and the Hypex s are a bit pricey, so I'll be watching this space as always for your measurements and observations. All the best Phil. Yeah, I would certainly consider looking at Class D these days for the size, price, and power utilization. Depending on electricity costs, it could take awhile to pay for itself of course. Overall good not to waste energy Great to see guys like Purifi pushing the envelope of no-nonsense engineering and increasing performance at reasonable costs

Class d amplifiers audiophile
Learn about classes of amplifiers. So keep reading to learn about the basics of the different power amplifiers classifications and what they mean. The different class of power amplifiers says nothing about the quality of sound but instead refers to how they are pieced together. The position of this label may vary depending on your device, so make sure to have a good look around! Class A amplifiers use transistors to amplify the incoming signal and require a base voltage of 0.
The 10 Best Class D Amplifiers
More ». The initial production run is being funded through a Kickstarter campaign. AV Industry from France has introduced their new Elipson MC Mini system, a compact Bluetooth amplifier to partner their speaker and source products within domestic hifi and custom integration installations. Last week we had a very pleasant visit up to Glasgow to Linn HQ to experience their new product. However, until midday today, we and the other selekt see what I did there , few journalists from the British Hifi Press, were sworn to secrecy about what we had seen and heard. Design by Jean-Yves Le Porcher, this new version of their Music Centre has a black satin finish chassis for the circular case, and a touch sensitive user interface under the CD slot. It also incorporates R2R DACs, requiring no modulation cables, allowing for the musical signal to remain digital up to amplification stages. Some more sophisticated DIYers may also be interested.
What Is Class-D Amplification?
Amplifier designers crafting high-fidelity audio systems increasingly are facing the same challenges as those in the power industry: the constant quest for smaller size and greater efficiency. To address this challenge, engineers are utilizing new integrated Class D amplifiers alongside the latest MOSFET technology in both discrete and modular formats. This article will consider the benefits of Class D amplifiers in general and discuss how the migration of key aspects of technology from power applications can enable designs and products that were not viable with the Class AB approach. Designers of high performance medium and high power audio applications traditionally have opted to use Class AB designs to meet efficiency and linearity goals.
Today we are going into detail on the hot topic of Class AB amplifier vs class D amplifier. Choosing an amplifier is confusing to many people. In addition, there are many varieties of amplifiers available in the market, and you may be wondering which one is the best. Moreover, which one is best for you and your sound system.
Those in the know about audiophile components recognise quality when they hear it. The Cyrus Stereo is a rare beast indeed — lauded by many as one of the finest power amplifiers of its generation, the Stereo is remarkable in its poise, absolute grip and astonishing dynamic range. Based on our in-house developed third generation Hybrid Class-D amplification, it is efficiently commanding, yet gloriously musical. Pin-point instrument positioning, beautiful balancing and crystal clarity are all signatures of this landmark amplifier. This combination provides enormous continuous power and superb dynamics. Height — 73 Width — Depth — Weight kg — 6.
Class D power going toe-to-toe with Class A refinement. PROS: Nonexistent noise and distortion; tube-like midrange purity; full tonal balance with stellar bass; effortless power delivery; top to bottom refinement. CONS: Ever-so-slight reductions in top-end extension, low-level resolution and dynamic life; slight mechanical buzz; binding posts could be nicer.
