  • 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. We've somehow packed a powerful headphone amplifier, ultra-clean DAC, Microphone ADC and RCA jacks into an extremely small box, all while being made in the USA.

    The ARC, make the move.

    Recently made the move from the tiny Fiio EK10 to the ARC. I wish I had done so sooner! After getting some more than capable headphones the ARC was my missing link. Both the sound quality and perceivable separation blew me away. I can't put into words how happy I am with this new soundstage I have the pleasure of listening to. THe sound is neutral and oh so crisp and clear. The DSP function adds buckets to the low end. This is certainly not meant to be used with music and only with games. Artillery now sounds truly terrifying. The DSP function works up to the bitrate of 96k when using the optical input, beyond that Windows throws a tantrum. To negate this I use the optical input for 192k and swap to USB input when gaming. The switch at the rear is very handy for this. Most times Windows does pick up on the change, if not it's just a mouse click away to swap them over. The unit is a nice sturdy chunk of metal. The volume knob is substantial and well finished. It's a very smart looking device that look right at home on a desc. The indicating LEDs do not flood the room with light, a welcome change from the previously blinding light the EK10 produced. To top it off their customer service is on point. Within minutes of emailing they had responded to my issue and the problem was solved. Overall: Perfect for gaming and listening to high quality audio files. A neutral sound. Great build quality and customer service.

    Works great most of the time

    There are times when it stops working completely and I need to reset the device to restore audio (never had this issue with my previous Mayflower AMP/DAC), aside from that it works great, although I do wish I could just leave my headphones plugged in and shut the power off to switch to speakers like I used to be able to with my ODAC.

    It's been almost two weeks since I have the Mayflower ARC, and let me tell you, it is pure awesomeness. The sound that it produces is amazingly rich and details that is almost beyond description; you have to listen to it for yourself. I paired it with a Sennheiser HD 600 for my Jazz music and a Sennheiser Game One which basically is a HD 598 with a mic. for my gaming and socialization needs. Before the ARC I had Astro mixamp, Steelseries GameDAC,etc., always looking for that great sound that my ears have wanting for 3 decades, now that search is over, I found it and I'm in love.

    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.

    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.

    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.
