On The Go HiFi Audio
This project will only be funded if it reaches its goal by Tue, November 19 2019 2:00 PM UTC +00:00.
HDTV brought premium video quality to the market and raised the expectations of consumers; now, the availability of HD Audio streaming is raising the expectations of audio quality. HD audio is often limited by the hardware on the user side. In the past, consumers would need to invest in bulky, dedicated hardware that was clumsy and quickly drained batteries. Ztella is designed to change the equation and bring HD audio to the mainstream. Ztella is small, simple, and efficient. Just connect it to your mobile phone and headphones and start rediscovering your music.
Ztella brings sound quality to a new level by bypassing the phone's internal conversion using a digital USB connection. Ztella supports sampling frequencies up to 384kHz with 32-bit depth (8x of CD sampling) and DSD 1-bit encoding up to 5.6MHz (2x of SACD sampling), which eliminates unnecessary sample-rate and bit-depth conversion. By using Ztella, the quality of your sound playback no longer depends on the phone or computer - Ztella handles all of the audio-specific tasks and ensures the best performance from any handset. Ztella, when used with a MQA-enabled app, also makes any phone capable of decoding Master Quality files, something that was previously limited to high spec HiFi smartphones.
MQA is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. Ztella is the smallest USB-DAC that includes MQA Renderer technology, which can connect to an MQA Core signal, like the TIDAL or Xiami Music (China) mobile app for example, and complete the final unfold of an MQA file.
Ztella uses the latest generation of SABRE DAC from ESS Technology and delivers a stunning 120dB SNR and 0.0006% THD+N performance. It delivers a balanced, clear and articulated sound in a wide soundstage.
With Ztella, the mic and buttons on your connected headphone are fully supported and passed back to the phone or computer, so there is no need to change headsets for a call or for gaming.
Ztella's integrated headphone amplifier will automatically detect and analyze the connected headphone to generate the ideal output levels. Ztella can deliver an output of 2Vrms to your high impedance headphone which is more than twice the power of a standard smartphone.
Ztella comes with a LED indicator that tells the sampling rate of the music content you are playing. The LED glows blue when it is idle or playing back SD content less than or equal to 48kHz. The LED glows red when it is playing back HD content greater than 48kHz. When playing MQA files, the LED glows magenta to indicate that the Ztella is playing back a fully authenticated MQA file.
Thanks to its use of USB 2.0 High Speed and Audio Class 2, it is plug-and-play compatible on Android, iOS, macOS and Windows 10. Its USB-C native connector plus the bundled USB-A adapter allows you to connect to all popular mobile phones and computers.
Based on a simple, less is more approach, Ztella is the smallest USB-DAC with high-end audio capability. Measured in at just 11cm and weighing just 5g, Ztella sets a new standard for portable HiFi audio. It is housed in a metallic gray aluminum chassis and does not require a battery.
Apple's latest iPad Pro series come with a USB-C connector so you can connect directly with Ztella. For iPhone/iPad using lightning connector, you can use our lightning adapter cable (please add HK$80 to your final pledge if you want to get it) or the Apple USB Camera Adapter Kit to bridge the connection to Ztella. This llghtning to USB-C receptacle cable is not designed by Zorloo (outsourced from third party supplier) and is not MFi certified.
Zorloo is a Hong Kong based company focused at bringing affordable premium portable audio products to music lovers worldwide. We have successfully funded 4 crowdfunding campaigns on Indiegogo and introduced our Z:ero/Aero digital earphone and ZuperDAC/ZuperDAC-S USB-DAC products. All of the above projects have moved to production and delivered to our supporters. The Ztella Integrated USB-DAC cable (MQA version) is a collaboration effort between Zorloo and HELM Audio. HELM Audio is a multi-award winning British-American venture focused on Audio Innovation and they will be introducing their own MQA adapter version to the market in 2020.
Ztella is a 12 month journey from concept to product. After our ZuperDAC-S product, we set our goals to improve not just the audio features and performance but also size reduction. We are really excited to unveil Ztella with all these goals being achieved. In addition, Ztella have already attained CE, FCC, RoHS and MQA certification.
This is the recording format used in CD and DVD-Audio. Regular CD is recorded at 44.1kHz sampling frequency. The latest studio DXD recording goes up to 352.8kHz/384kHz which is 8x of CD. With Ztella, you can listen to the highest level of studio recording without any compromise.
This is the recording format used in SACD. It is based on an alternate 1-bit density based encoding at extremely high sampling rate starting from 2.8MHz. With Ztella, you can enjoy DSD recording up to 2x at 5.6MHz sampling.
All pledges will be shipped using e-Express or registered air mail. Tax and duties are not included. Once we ship out your pledge, we will notify you the tracking information through email. Please add email@example.com to your contact list in order to avoid the notification email accidentally falls to your inbox spam.
Risks and challenges
We have already completed a few pilot runs with full functional production samples. All toolings are tested and verified for mass production. Ztella already received CE, FCC, RoHS and MQA certification. We will have production running in parallel with the campaign. The risk is very low and we target to start the first shipment in December.Learn about accountability on Kickstarter
