Product Description

Micca OriGain AD250 Integrated Amplifier with USB and Optical Digital Audio DAC

Micca home audio products are designed to fit the evolving needs of the modern music listener. Through adaptive product design and application of new technology and techniques, our products are made to be simple to use, yet exceptionally capable and versatile. For a compact stereo amplifier with an abundance of connectivity options, look no further than the OriGain AD250. It's small enough to fit into anywhere around a home or office, and built to the same high performance and quality standard that is associated with all Micca products.

Experience the convenience and superior quality of digital audio. Connect the OriGain AD250 to a computer via USB, or to a TV's optical audio output for high fidelity audio playback. Note that the AD250 supports PCM audio, and does not support surround sound formats such as Dolby or DTS. Please consult your TV's manual to ensure its optical output can be set to PCM.

Sleek and Compact

Compact stereo amplifiers are the best choice for powering speakers in the home or office, taking up little space while producing exceptional power output and audio clarity. Despite being less than 1/40th of the size of a standard stereo receiver by volume, the OriGain AD250 pushes 50 watts out to each of its two channels. All switches and controls are conveniently placed on the front panel and easy to see at a glance.

In a case of form following function, the OriGain's all metal construction is durable and provides superior heat dissipation, yet the smooth matte black aluminum finish imparts a uniquely modern and sophisticated appearance.

Listen For Yourself

Use the OriGain as part of a new compact stereo build, or as replacement for a large and obsolete older amplifier. Discover how powerful and convenient a compact amplifier can be by trying the OriGain in your home or office.

Efficient, Powerful, Dynamic, Clean

The OriGain AD250 utilizes clean and efficient Class-D amplifier technology to deliver 50W x 2 power output into 4Ω speakers with less than 0.5% total harmonic distortion. Power into 8Ω speakers is 30W x 2. Careful design and board layout effectively suppresses background noise to imperceptible levels even at maximum volume. Along with a frequency response that is audibly flat, the OriGain's audio signature is transparent and accurate.

Use the OriGain with speakers of any size, from small cubes to full size floor standing speakers. Slim profile 5-way binding posts can support speaker wire with banana plugs, pins, spades, or bare wire. The built-in volume controlled pre-out jack can be used to easily add a self-powered subwoofer.

Class Leading Design

The OriGain uses the exceptionally well performing Texas Instrument TPA3116D2 amplifier chip. Owing to its excellent power output efficiency and flat frequency response, the TPA3116D2 is well established as the benchmark stereo amplifier chip. Additionally, the OriGain AD250 uses the C-MEDIA CM6510B USB interface and the well regarded Wolfson WM8740 DAC for digital-to-analog conversion.

Versatile by Design

The OriGain is available in two models: A250 and AD250. The differences are as follows.

Both A250 and AD250:

50W x 2 integrated amplifier
Analog audio input
Stereo speaker output
Pre-out output for subwoofer

AD250 Only:

USB digital audio input
Optical digital audio input

Good amp with a few caveats

Reviewed in the United States on January 12, 2018

The media could not be loaded.

UPDATE 2/28/18: Downgrade to 3 stars because of optical input and out of phase issues. After a month of use, I started hearing really bad noise and the audio was cracking up. I would also hear random pops from time to time. I ran a frequency test and found significant amount of noise when playing high frequency tone. The noise is noticeable even at low frequencies, but it starts to get really bad at 5kHz, and it completely overwhelms the tone above 10kHz. This only happens with the optical input as I didn't hear any noise when using the USB or the analog input through a separate DAC with SPDIF port. I contacted Micca but they wanted to charge $5 shipping for exchange because it's been over 30 days since I placed the order. In the end I returned through Amazon. Amazon's 30-day return policy starts counting when you receive the package. I then purchased another unit thinking that the first one was just defective. Turned out the 2nd unit also had the same problem, just not as bad. Maybe if I leave it running for a month it would become like the first unit. If you plan to use the SPDIF port, look elsewhere. The 2nd unit also had the problem of out of phase audio which the other reviewer pointed out. It's easy to fix, but the high chance of getting a defective unit shows you the build quality you can expect from these units.

I bought the AD250 DAC/amp along with the Micca MB42X bookshelf speakers and the Dayton SUB-800 subwoofer to replace LSR305 in a desktop setup. The main reason why I replaced the LSR305 was because I couldn't stand its static noise blasting at my face 24/7. AD250+MB42X put out much less static noise when there's nothing playing. I have to put my ear within 6 inches of the speaker to hear any noise, which would never happen in normal use, whereas I could hear the LSR305 noise from 2 or 3 feet away.

I also looked at a bunch of other amps including the Lepai LP-2020A+, the SMSL SA36A, and the Dayton DTA-120, but ultimately I chose Micca simply because of their reputation on the MB42X. I can't comment on the sound quality as this is my first real setup and I'm just a casual listener, but so far I haven't had any major issues. However, there are a few minor issues that can be annoying.

1. Power on/off click and pop noise. See my video for this. This is a very common problem in audio amplifiers and especially speaker drivers. If you do a quick search on "TPA3116D2 power on pop", you will see loads of people having the same problem with this chip. I'm not familiar with this chip so I can't say for sure, but usually the problem can be avoided by careful system design. This is not a deal breaker, but at $100, Micca should do better than this.

2. Sound is unbalanced at low volume. The right speaker is clearly at a higher volume than the left speaker. Again, this is not a deal breaker because no one would listen at such low volume, but it can create an illusion that the right speaker is louder when you first power on the speakers.

3. When using the optical input, lowering volume to 10-20% on Windows can sometimes create loud, short bursts of static noise. I've never had this problem when using my old Orei DA21. Again probably not a showstopper, as most people would maximize the source volume and adjust the volume with the amp knob to maximize signal integrity, but this could be a minor inconvenience for people who don't have the amp at arm's reach.

Overall I'm still happy with the purchase, but it would be great if Micca can iron out these issues in the next version.

Fantastic Value

Reviewed in the United States on December 4, 2017

For the price, the OriGain is almost unbeatable. It's a speaker amp with an integrated DAC for under $100. It powers my ELAC Debut B6 speakers relatively well, although at 50w per channel, it's not the most powerful amp in the world.

As is typical of the Wolfson DAC-based audio hardware I've owned, the integrated WM8740 converter is on the smooth / laid back side of the audio spectrum. When comparing with the fixed output mode of my Audioquest Dragonfly Black through the amp section of the OriGain, I notice right away that the Dragonfly has better imaging, separation, and gives the Debut B6 speakers a much-needed boost in the treble region. That said, the integrated DAC is perfectly fine for television / movie / computer listening. If I'm listening to music for an extended period of time, however, I'll plug in the Dragonfly via the included analog cables.

The hardware itself is really nicely built. It looks serious, feels heavy, and has a nice textured surface on the (steel?) enclosure. As you can see from the product photos, the power brick is gigantic - it's actually larger than the OriGain itself. I don't know if that translates into more power, but it's worth noting. A single red LED sits in the middle of the unit and doesn't light up the room at night like practically ever other piece of electronic equipment I own. The switches all toggle back and forth with a sturdy click. Not including the power brick, the footprint is actually small enough that it could amost be classified as portable.

Micca OriGain AD250 Amp - High Quality, Compact, Top of Class

Reviewed in the United States on February 12, 2018

Verified Purchase

I was looking for a quality, but fairly compact, speaker setup for my PC. (I grew tired of buying low-quality, all-in-one speaker systems designed for PCs, like those from Logitech, Klipsch, and many others; They may sound decent for a while, but quickly start having problems.) Micca is constantly mentioned and highly regarded in many "budget audiophile" and "best-for-price" audio hardware reviews from many different corners of the web. The OriGain AD250 delivers on these promises. It does indeed seem like one of best compact amplifiers for the price.

Beautiful build quality and attention to detail, especially in this price class. The same can be said of my MB42X speakers, and seemingly all of Micca's products. Mine was combined with Micca MB42X speakers and Dayton Audio SUB-800 subwoofer. Sounds fantastic all-together, and makes for a quality stereo setup, especially if size is an issue. The AD250's brains consist of Texas Instruments TPA3116D2 Class-D amplifier, along with Wolfson WM8740 DAC, and C-MEDIA CM6510B USB interface. Beautiful sturdy steel construction, with clean and simple labeling of ports and functions. Large volume and power control knob, with distinct machined indicator. Subtle red LED power indicator. Satisfying and simple toggle switches for selecting audio inputs. Extremely useful "pre-out", perfect for connecting a subwoofer. Includes all the cables you need to get started (optical cable not included nor absolutely necessary). I can happily recommend this product. Bravo to Micca. As others have mentioned, if there was somehow room for a headphone output, that would really make the OriGain amazing. I also appreciate that all relevant product information is provided cleanly and neatly through a top-notch manual, as well as descriptions and photos at Amazon (and Miccatron website hopefully soon, product page not yet available, but they will send manual in PDF). Would love to know more about Micca, but it's a bit hard to find further information.

More specs and highlights: Power Output: 50 watts x 2 at 4 ohms, 30 watts x 2 at 8 ohms, TI TPA3116D2. Input Analog: RCA, stereo. Input Digital: Optical S/PDIF (24 bit, 192 kHz, Wolfson WM8740), USB (24 bit, 96 kHz, C-MEDIA CM6510B). Output Pre-Out: 3.5 mm, stereo. Output Speakers: binding posts (5-way), stereo. Frequency Response: 20 Hz - 20 kHz. Distortion (THD): under 0.5 %. Power Input: 24 volt, 4.75 amp, external adapter. Dimensions: 5.5 x 3.5 x 1.5 inches (D x W x H, rounded). Weight: 2 pounds. Color: Black (and more black).

Defect: My first OriGain AD250 was partially defective. After some research and testing (phase, imaging, connecting other speakers), it seems that one set of the speaker terminals on the OriGain was reversed, resulting in "out of phase" audio. This is especially noticeable with sources containing strong stereo or surround imaging (videogames, etc). Find a phase test (like those at AudioCheck.net) to properly verify. A simple reverse of polarity for just one speaker corrected the phase, but I was worried about other issues, and Micca wanted to inspect the unit and seemed to genuinely care about the problem. Replacement was sent very quickly, and has been performing perfectly (no payments, just a trusting swap, with bare units sent and returned in bubble mailer). Only one star has been removed for now due to this problem thanks to their excellent customer support. I've now noticed that Micca (official Micca Distributor) seems to have stopped selling this product for the time being. That said, I'm enjoying my OriGain and new speaker setup even more every day, and hope Micca can easily correct some of these odd issues.

Fantastic product

Reviewed in Canada on July 24, 2020

I was in the market for a small amp for my desk. I did see a few alternatives with remotes and/or digital control interfaces, but I did not want to fuss with anything. This Micca amp stood out as it had hard physical buttons, lots of input options, and most importantly, it looked great. The power output is a bit on the weak side but for a desk use, it wasn't going to be a huge issue. In fact, it can get louder than it needs to. I normally put it at around 20% volume and I think it's pretty loud for a normal music listening experience.

The product feels really solid overall and there is no hiss with my Micca RB42s. Also I really appreciate the subtle LED indicator on the front.

The input selection switches are a bit too stiff for my liking but that's more of a personal preference. Nothing wrong with the product itself.

A lovely product, overall. Would definitely recommend!

Awesome AMP/DAC with pre-out/sub-out

Reviewed in Canada on October 4, 2018

Verified Purchase

Bought this little device to mate to my Micca COVO-S and powered Kanto SUB6. It has exceeded my exceptions. Beautiful metal case and knob, gold-plated connectors, subtle red LED on front.

I connect it via USB to my laptop. When I'm browsing the internet I turn off the amp and audio does through my laptop speakers. When I'm ready for music I turn on the amp and Windows automatically transfers sound to my speaker set-up. Works seamlessly. One thing to note - you won't be able to adjust the volume through the computer when using a DAC. You'll need to use the volume knob on the device. Not an issue with this product, it's true for all DACs.

It has a pre-out/sub-out, which is EXTREMELY difficult to find on small amps. This is an excellent feature that allows you to connect to a powered subwoofer. Without it you would need to split the analog signal that enters the DAC. Not ideal.

Working exactly as expected

This is an excellent amplifier for a small studio or for your computer desktop. It is very small and it gives a great sound. I use it for my computer using USB audio and for my analog radio tuner. It works well with both. Note that the USB audio cable must be plugged directly to the computer. In my case it didn't when connected through a USB hub. Note that the sound is very flat. It is expected from studio equipment. If you want more flavor to your sound then maybe you will prefer a none professional equipment. It is a matter of taste.

I checked a lot of reviews on YouTube as well as on Amazon before I purchased. I'm very happy with the products, got them 2 days earlier than expected and found the whole process about as professionally done as I could have hoped. I'm sure I will be back to Amazon for future audio gear especially. The speakers are quite accurate and the amp offers inputs for analogue or SPDIF connections which suited my needs perfectly. The OriGain is offered in a simplified version without the DAC but for the small extra expense, this version provides better flexibility.
