Astell&Kern is the ultimate portable high-fidelity audio system capable of studio Mastering Quality Sound (MQS)


After successfully launching the AK100 and the AK120 models, we asked ourselves, “What is the ultimate sound quality?” After much consideration, we decided to move a step further with our goal, which is to deliver the sound “exactly as the artist had intended” for us to hear. Moving from the AK100 to AK120, we decided to provide a Dual DAC setup to create better left and right channel separation with clearer sound quality. We thought that the Dual DAC setup would be enough, but while developing the AK240, we felt the need to further improve sound quality in order to accurately reproduce the original sound recording. After countless hours of research and testing, we were able to find the answer.
            The answer was to create both a balanced output and native DSD playback through the Dual DAC setup.
            Now with the AK240, we can dare say that we have gotten “that much closer” to the sound quality of the original recording.



Key Specs Image

DSD (Direct Stream Digital) is a digital audio file format originally developed for SACDs (Super Audio CD). Regular digital audio file formats such as PCM (Pulse Code Modulation) is separated into 65,000(16bit) to 16,700,000(24bit) of information on the Y axis, and 44,100(44.1kHz) to 192,000(192kHz) across the X axis for digital signals. DSD files have 1bit (0s or 1s) for Y axis and is separated into 2,800,000(2.8MHz) to 5,600,000(5.6MHz) of information for X axis.
            Compared to regular audio CDs with 16bit/44.1kHz PCM format, SACD’s recording frequency goes up to 100kHz and the dynamic range goes beyond 120dB while maintaining sound clarity during the transmission.

About Redfli Image

Redfli Electronics was started as a company dedicated to providing Red Carpet Customer Service coupled with exclusive, handpicked product lines that fit any need! After seeing the lack of quality, expertise and service to customers available in big box stores and other reputable companies,the owner of Redfli decided to take his knowledge and passion for gadgets and mix it with his expertise for business to create a better audio/video company.


A/V Revolution Iconelectronics REVOLT? What is an A/V revolution? Simply, it is doing things in new ways that break the mold; ways that move us above others with unparalleled customer service and exclusive, handpicked product lines. We are not your everyday A/V dealer and we don’t want to be. We want to be better!


We only carry lines that we believe in 100%. We do not pick up every brand possible, helping             us to stay specialized and have advanced knowledge of the products we do sell. Our                philosophy is to provide a Red Carpet Customer Service experience you will get no where else!


Buying from Redfli you will find the service and personal attention that most companies have lost. We build long term relationships, not one time sales with our customers. Once you buy from us and experience  the difference that true “old school” personal touch has to offer, you will see that Redfli is the premier source for any of your audio/video needs.


We are more than just an Audio/Video retailer and online dealer. We are also a fully dedicated and staffed custom system design and installation company.

Authorized Dealer Image

Authorized Dealer IconIs Buying from an Authorized Dealer Really that Big of a Deal? It is a huge deal and here’s why. If you purchase a product from someone who is NOT an authorized dealer you WILL NOT get warranty period. No matter what they say, they cannot provide warranty.


Individuals selling these types of items are almost always selling “B Stock” items or those that have been refurbished and trying to sell as new. These are items that the company has deemed not good enough to send to an Authorized Dealer. There is a reason there is a discount. The chances of one of these type of products breaking is far greater than that of the “A Stock” highest quality products we offer. Couple that with no warranty and you are maximizing your risk.


What does no warranty mean? It means that if anything were to happen you are on your own. Every penny it costs to get fixed will come out of your pocket. By the time you pay to get it fixed, have to buy a new one or both, you will end up spending more money and             certainly more time than if you had purchased a legitimate product in the first place.


Need proof? Call any of the companies directly and see what they say. They usually have it plastered all over their warranty page about unauthorized selling. Don’t be fooled into thinking they won’t know either. They track every serial number on every product that is sent out and to whom it goes to. When they see that it was purchased through a non-authorized form the warranty is completely void.


Why go into detail about this? The reason for this warning and advice is to save well meaning customers from nightmares and lost money, things we have seen far too many times. We only want you to have worry about enjoying your product, not whether it will work or whether you’re covered in the event             something stops working. We are here to ensure your absolute enjoyment and proper operation of the equipment you purchase from us.
