Hear ye, all Head-Fiers! We bring good news:
We are sponsoring an international Review Tour of the new Questyle CMA Fifteen!
Zach from Questyle Technology here. It’s been a while since we released our last product – the CMA Twelve in 2019. But now in 2021, we are back with two new products: the CMA Fifteen, Questyle’s newest flagship DAC/Headphone Amplifier, and the M12, a mobile Hifi Headphone Amplifier with DAC. It is with great pride that we introduce these extremely powerful devices to all of the Head-Fi community!
The M12 has been on the market for a couple months now, but the CMA Fifteen has just been released recently. And we want to let you get your hands on it to try it out. So we are planning an international Review Tour!

About the CMA Fifteen
The magic of the CMA Fifteen lies in Questyle’s patented “Current Mode Amplification” technology. As its name suggests, Current Mode Amplification uses current—instead of voltage—to amplify audio signals. It is a state-of-the-art technology in audio amplification, leading to tremendous performance differences when compared to traditional audio amplifiers. The CMA Fifteen celebrates the 15th anniversary of this groundbreaking invention.
For its DAC, the CMA Fifteen uses the ESS ES9038PRO, and supports up to 32bit/768K and DSD 512 master band formats. We specifically picked this DAC because of its native current-type output—which, when paired with our Current Mode Amplification circuit, operate in harmony to achieve true system-level lossless purity. We at Questyle like to call this Current Mode².
The CMA Fifteen has also built further upon its predecessors with new input options (including USB-C, analog, and Bluetooth 5.0 with LDAC support), as well as numerous other improvements under the hood.
In short, the CMA Fifteen is the culmination of 15 years of research at Questyle, and with it we have brought Current Mode Amplification to its highest pinnacle yet.

About the Tour
We are very excited to get our precious CMA Fifteen into the world, and in order to help our baby grow, we are planning a small tour across the world over the coming months. If you’re interested, please read more below.
We will begin with one tour in the USA, and one tour in the EU. However, even if you’re not located in one of these two regions, please sign up for the tour below if you’re interested. If there are enough reviewers interested in a specific region, we will certainly consider holding a tour there.
How to Apply:
Please complete this form. Once completed, we will post the final tour schedule here in this Head-Fi thread, as well as contact each of you individually.
Tour Logistics:
- Based on who signs up via the form above, we shall group reviewers by geographical location. We will start a group PM for each geographical location, and we can keep each other updated in this PM.
- We will then send the Questyle CMA Fifteen Tour Review Package to first reviewers in each group.
- Questyle will cover the import tax to the first reviewer. Please help us to control our tax expenditure wherever possible. Other taxes or duties will subject to discussion within each tour group.
- Each reviewer can keep the Questyle CMA Fifteen Tour Review Package for up to 14 days. Please plan your review period in advance, and be prepared to ship/pass the package on the 14th day of your review period.
- Each tour reviewer is responsible for paying the shipping costs to the next tour reviewer. You can use ground mail to reduce the cost, but please use trackable mailing services with signature required.
- The last reviewer in the group is responsible for shipping the Tour Review Package to a designated address to conclude the tour. If the return address requires international shipping, Questyle will cover the mailing cost incurred.
- If we have more than one Head-Fier from the same metropolitan area/city joining the tour, we encourage you to pass the equipment in-person to reduce shipping cost and mailing time, and then share the final logistic cost together.
- Questyle reserves all rights regarding the selection, grouping, and scheduling of reviewers on this tour.
- Tour members will need to provide their full name, address, email and phone number for purposes of the tour. This information will not be published, but each member will receive the info of the next person he/she needs to ship the CMA Fifteen to.
Review Writing Guidelines:
- By signing up for the tour, you agree to write and post a formal review within 14 days after your review period. You also agree for Questyle to use your review for sales and marketing purposes.
- You have complete freedom to write your review whichever way you desire. We encourage you to share any impression you have, as long as it represents your true feeling and opinion toward the product. Your review does not necessarily need to be positive, it just needs to be honest.
- We are particularly interested in the associated electronics you used during the review. Please include the details of your audio setup when you post your review.
- We want your reviews to be read by as many current or potential users as possible, so please share your unboxing photos & videos and/or short impression in the Questyle CMA Fifteen Official Thread, as well as post your final review on the HeadGear section of Head-Fi forum.
- You are also welcome to share your photo/review/impression to any social media or local audio-related forum/blog/magazine etc (making sure to let us know where you post, so that we can hear all that you have to say!) If you post on other social media, make sure to use the hashtag #cmafifteen
We are incredibly excited to share the CMA Fifteen with you, and we look forward to what the Head-Fi community thinks about our newest addition to the Questyle family.
