  • ARC (Aural Resonance Cascade) is a project 2 years in the making. Over the years of selling our famous Objective2 and ODAC line of products we've received incredible feedback and suggestions in how to improve our products. We took all of it and designed a completely new platform from the ground up, only carrying over the enclosure from the Objective2 line. Our main focus was with the ARC was to bring in modern design and components, doing it better than the competition.

    ARC tastic

    Bought the ARC to replace audioengine D1 and straight away the sound from headphones was better. The unit is well designed and sturdy, sound is excellent and does what it is supposed to do! Just buy one and move on with your gaming life.

    ARC

    I'm using the ARC with a Sennheiser PC 37x for gaming. The sound quality is much better than my onboard card. Not that it was bad, but the moment I plugged in the ARC, there was a significant improvement. The sound is very clear and can help while gaming. The ARC has one big bonus, Mic Input. The Sennheiser has a very nice mic and now my co-players can even hear me better (not that this is always a good thing :-) For music consumption I use an audio-technica ATH-M50x, even fully cranked up, no distortion whatsoever. Not that you can listen for very long before you're deaf :-) Tried the DSP, but it's a little to bass heavy for my taste (listen mostly to hard rock and metal). Overall a great product.

    Highly satisfied

    A Dac/Amp with a mic input? Yes, love it. Will it be overkill for my 50ohm Game Zeros from Sennheiser? Nope. Will it power my 250ohm DT 880's? 100% yep. The DSP mode is a bass head's dream too. I've been in a struggle with sound cards and I'm so happy to have put that behind me- I Highly recommend the ARC to anyone looking for a solid solution to their audio woes. Also, the customer support absolutely fantastic!

    Great For All Multimedia Needs!

    I love this little thing. I use it on my PC and PlayStation 4 Pro. I've used it with my Audeze LCD 2 C's and my Philip's Fidelio x2's with an Antlion Modmic. Works AMAZING! Good sound. Nice bass. I love the DSP, gives it that extra push while gaming. So glad I got this. The chat audio is clean and loud too, when you are gaming with others. Perfect. Would buy again.

    ARC

    Great product. I had been searching for some time for a quality product instead of using Gaming headsets. Many quality games now come with a certain degree of positional sound and if you use a quality headset and this amp/Dac, you can really enjoy the experience. What is special about the ARC is the Mic in port. Most all DAC's don't have that option. I don't use it, but having it available is a great option, especially in multiplayer games where you want to communicate with other players on your team. I have a new computer and did not order a sound card and just plugged in my ARC. It does have modern on-board audio, but I chose to use the ARC instead as it really drives the quality of the sound. You can adjust, in many games, the base and treble, but the sound is clear and crisp. Extremely pleased with this product.

    As Advertised

    I found out about the Arc through some youtubers and the product is as advertised. I believe it was Zeos (z reviews) who said the DAC is as good as a DAC needs to be and he's right, the sound is extremely clean. The AMP does what it needs to do, I'm using 600 OHM Beyerdynamic DT880's and I'm usually around 1:00 with the volume knob, if I crank it to max the sound remains good all the way up, no static, no cracking etc. The mic input is a nice feature, running it through the ARC clearly made a noticeable difference in the mic quality. Final point, I ordered this on the website and had it shipped to Canada, it took a few weeks but had no additional charges which was appreciated.

    Great Sound and Helps with Cables

    After eyeing this product for a couple of months and looking for others like it, I decided the ARC was a relatively unique product. It's neutral response like the O2+ODAC and option for microphone input at this price range weren't easily matched at the time of purchase. The product sounds great and the DSP bass boost adds just enough to help regain some depth for certain open-back headphones but not muddy those frequencies. The microphone input is great for reducing the number of cables that have to cross my desk. The quality of audio played through it is astoundingly better than the on-board audio for any electronic device I've used. Comparatively, all frequencies have much tighter response, especially the lower. Its driverless operation is also great, allowing me to switch OS's without any worry. The biggest drawback to this product is its quality control. The first unit I received was DOA. But Mayflower Electronic's customer service was very quick to respond and sent me a shipping label immediately. After receiving the second unit I got to enjoy it for a little while, where after a time it went sour again. But, support was still very helpful and sent a third unit. Shortly after receiving the third, I noticed a few quirks on occasion, such as the volume knob not having any effect, regardless of OS. The only solution was to unplug it from power for a short time. It's been a few more weeks now and the aforementioned bugs haven't surfaced again, everything seems well and good now. Despite the difficulty involved with receiving a functional unit, Mayflower Electronic's helpful support and its great sound saved its score for me. With a working unit, this product is definitely worthwhile.

    Perfect entry level audiophile dac amp

    Upgraded from a Xonar Phoebus sound card to pair withmy HD 6xx. No problem powering them, the DPS is a nice touch when playing FPS games . Sound is Crystal clear and balanced the way I love it. Set on low gain and still plenty of juice for the 300ohm 6xxs. The rubber feet keep the guy in place on my desk. The USB cable could be longer but its not bad, and the amp still makes a small click sound when powered on. But those are pretty irrelevant compared to the quality and performance of the product. Perfect for my first external dac amp 10/10

    ARC

    Powerfull and convienent! More than capable of driving my K7xx. I leave my stereo hooked up to the line out on my PC ant the ARC takes over as the output when I turn it on. Too simple. No setup. It just works. The DSP aka bass boost adds a natural sounding low end boost making explosions and gun fire a bit more present. With out the DSP on you get a clear sound across the frequency spectrum. All the low end is still there. Just not in your face. If you have looked into this unit and wonder if it may be over hyped. It's not. Get one and see for your self. One of us. One of us. Lol

    ARC

    This has been the best time ever since I received my ARC. It works so well with my PS4.
