Questyle M12 is an advanced mobile HiFi headphone DAC and amplifier featuring an advanced ES9281AC ESS Sabre DAC chip providing best-in-class audio performance with ultra-low distortion. Questyle M12 is capable of providing clean and powerful output thanks to the brand's self-developed "Current Mode" independent headphone amplifier technology.

Powerful Driving Force With Advanced Current Mode Technology:-

Questyle has developed an advanced "Current Mode" technology that is the main USP of their award-winning products. Questyle has brought that technology for mobile users with the portable M12. M12 is not limited by the power of OPAMP chips, it has ultra-high current output capability and control. Even with such a powerful driving force, the device has an ultra-low distortion rating of just 0.0003%.

Intelligent Impedance Adaptive Technology:-

Questyle M12 features low and high-gain modes that it switches automatically adapting to the power requirement of the connected headset. M12 features an intelligent impedance adaptive technology that changes the gain mode as per the impedance rating of the connected headphones. It switches to the high gain mode for headphones with 70 ohms and above impedance below it sticks to the low gain mode. When we connect 600 ohms headphones it switches the output automatically to line out mode with a 2V output level.

MQA Decoding Support:- 

Questyle M12 supports MQA rendering and completes the final development of MQA files. When the LED indicator is glowing magenta color, it means the M12 is rendering the MQA file and the final development of the MQA file is being completed. 

Hi-Resolution Audio Signal Decoding:-

Questyle M12 features an advanced ES9281AC audio signal decoding chip by ESS Technologies. It provides high-resolution audio signal decoding with ultra-low distortion and pitch-dark noise-free background in the output. M12 supports  PCM decoding up to 32-Bit/384kHz and DSD up to DSD256 natively. 

Compatible With Most Devices:-

Questyle M12 is designed and developed keeping in mind support for most devices straight out of the box. It can be used with any Android device with Android V5.1  and above. For PC is supports Windows 10 and MAC systems with no requirement for any driver installation.

Hokey religions and ancient weapons are no match for a good blaster at your side, kid
Format: Paperback
Star Wars: The Screaming Citadel is a crossover collection of the main Star Wars comic series and the Doctor Aphra series. The Arc revolves around the Queen of The Screaming Citadel being the only one who can open a relic containing an ancient Jedi master. Aphra then teams up with Luke Skywalker and we have our crossover event. The story itself is good. A queen with parasitic bugs controlling a planet is uncharted territory for Star Wars and it works. There were great action moments, plots painting the Empire in a morally grey light than the traditional evil one. Doctor Aphra Marvel's golden girl character was funny in this and her chemistry with Luke worked. It didn't feel forced like Marvel was trying to use the Original Characters to build-up their new ones. Where this comic fails is the inconsistent art style as this is a collection you get different art with each issue. Its starts of good and then takes a nosedive in the Aphra issue in the volume. Bad art aside Screaming Citadel was an enjoyable crossover. Doctor Aphra is the best new character to come out of this new Marvel Disney run. Screaming Citadel is worth the read it was a nice crossover that delves more into the Fantasy elements of Star Wars and works as Star Wars has been Space Wizards since 1977.

What a ride.
Format: Paperback
How these two come together with the rest of the iconic characters is just so fun. Add in a Screaming Citadel and you're in for one hell of a ride. If you love Star Wars, pick it up. It could read as a stand-alone if needed. Part of the Doctor Aphra comics.

Absolutely top-knotch
Format: Kindle
9.5/10 This is the pinnacle of Star Wars comic books. A great way to tie in their Indiana Jones character in Aphra and the mainline series to tell an amazing story. Only complaint is a couple of the issues artwork I was not a fan of. I like the more realistic look. Just make sure you read Aphra book 1 and the previous SW books to understand it better. Aphra book 1 being more important

Star Wars embraces fantasy
Format: Paperback
This is Star Wars at its' strangest, and that's a very good thing. Luke and co. fighting through what could easily be Dracula's castle is a truly unique experience. I don't wish to say more for fear of spoilers. As a note though you will get more out of this if you've been following the Star Wars and Dr. Aphra comics. However you can get by without that knowledge as well.

Gothic Star Wars
Format: Paperback
This trade paperback collects all the issues for the Screaming Citadel story spread over several titles, including the main stay Star Wars series and the Dr Aphra book. As one might expect from a story spread over different titles with different artists and writers, the presentation varies. The art is all over the place. In the Marco Checchetto-drawn initial issue, everyone’s favorite amoral artifact hunter, Dr Aphra, is a striking space vixen. But in the following issues she’s hardly recognizable as the same character--mousier, if still menacing, in her trademark Russian tanker’s hat. To a lesser degree, the same is true for the other characters, including the main SW group. It’s understandable, but a bit disconcerting. The story centers on Dr Aphra, who, in need of a Jedi for one of her typically nefarious purposes, recruits Luke into her scheme. Unfortunately for Aphra, she’s up against a more ruthless foe in the harlequin-looking vampire-like Queen of the Screaming Citadel. Before long, the rest of the group has to show up to rescue them. It’s a gothic story, set in scary castle—not the usual Star Wars fare. There are some good points. Dr Aphra’s almost sociopathic outlook is always good for a few choice lines, the “murderous machines” Bee Tee and Triple Zero are on hand for their own gruesome commentary and some of the Queens hench-people, while not given much to do, are interestingly designed. But overall, the horror movies plotline didn’t seem much like Star Wars to me. Recommended for those who enjoy that type of story, or completists.
