    Album of the Evening

    I recently started listening to one complete album from start to finish every evening. It's really great to sit down, no Internet, no phone, no iPhone, no i-anything and close my evening out with uninterrupted music. There's nothing like closing out each day on a great note, no pun intended. I want to start this thread for people interested in doing the same thing. Listening to an album every evening and posting simply the artist and album information. Doesn't have to be a picture or the cover or a link or anything. It's more about enjoying this wonderful hobby. I'll start with my Album of the Evening for tonight: Artist: Boston Album: Boston
  3. New press release: FOR IMMEDIATE RELEASE: Ayre Acoustics, Inc. introduces the QX-5 Twenty – The Digital Hub. Boulder, Colorado, USA - 27 April 2016 - Ayre's latest entry in the world of digital audio combines a decades-long record of ground-breaking innovation in both digital and analog audio with revolutionary features to set a new benchmark in the field. Every conceivable digital input, including Ethernet, StreamlengthTM asynchronous USB, S/PDIF (in three different formats), and even direct connection to thumb drives and NAS storage allows for unlimited flexibility and convenience. Streaming with both Tidal and Deezer are fully supported, and Roon ready control is directly integrated as well. Whether your music library comprises physical media, computer-based files, or streamed from the highest quality lossless services, all are seamlessly accessible with unprecedented ease. Ayre is proud to partner with ESS Technologies (www.esstech.com) to debut their new flagship D/A converter chip, the ES9038PRO in the QX-5. This advanced device builds on ESS's award-winning technology to set new standards for linearity and dynamic range. Combined with Ayre's custom minimum-phase digital filter, implemented in a low noise FPGA, this synergistic integration renders an astonishing level of detail and purity. Delivering all of music's emotional power to the listener - regardless of format. Ayre has also partnered with Morion (www.morion.com.ru) to develop a new high-performance crystal oscillator that offers the lowest levels of phase noise in the industry. Morion has decades of experience supplying satellite-grade crystal oscillators, including those powering the guidance system of the International Space Station. A specially developed new doubly-rotated cut quartz crystal allows this high level of performance to be achieved without the need for expensive temperature-controlled ovens. Precision timing is at the heart of conversion between the digital and analog domains, and the ease and fluidity of analog is fully realized for the first time with the QX-5. The Ayre QX-5 Twenty – The Digital Hub. This is music! ABOUT: Ayre Acoustics, Inc. has been steadily developing a full array of new audio and video technologies since 1993. Pioneering the use of zero-feedback real-time amplification, built on a foundation of the highest performance power supplies, and maximizing the circuit's performance capabilities through the use of fully-balanced, differential circuits from input to output, Ayre's designs have continually won countless awards for decades. All Ayre products are designed and built by hand in Boulder, Colorado, using only components from the highest quality supply partners in North America, Japan, and Europe.

    Audirvana Plus 3 (official thread)

    Hi Guys - In anticipation of Audirvana Plus 3, and seeing how large the AP 2.6 thread has become, I started this thread as the location for all AP 3 conversations.

    Audirvana Plus 3 for Windows (Official Thread)

    As the title says and per the request of the CA Community, here's the official A+ topic for Windows.
  6. Now that the Aries has been released, the discussion of the hardware is in this thread. The previous discussion can be found here -> Auralic Aries UPnP Renderer: Double DSD Over Wi-Fi

    The New CA Issues and Feedback Thread

    Hi Guys - This thread is here to log any issues that you find with the site and to provide any feedback you wish. As usual, all feedback, good, bad, indifferent, is welcome. It has been a long weekend and I'm sure I missed a few things in my final run-through of the site. Please let me know what you find. In addition, I still have a lot of housekeeping to do and will get to it as soon as possible. A few issues I am working through: Front page articles need some of the code that didn't transfer over from the previous site removed (it's still visible in some articles). Article, not forum, attachments need to be re-attached (this will keep e busy for a while). Blog attachments need to be re-attached (this will also keep me busy for a while). I am creating URL redirect so some of the old URLs / web addresses will still work. Please let me know if you want your favorite thread to still work with the old URL (test to make sure I haven't created it already). Notes: Support for the iOS and Android apps has been discontinued. P.S. I still have access to the old site incase someone thinks they lost something.
  8. Just received this vi email: The Optologic DAC The Formula Dac is the first in the aqua - acoustic quality's production to show a proprietary D/A conversion system, that we name Optologic Dac. This conversion system follows the same multibit technology (already used in the previous world acclaimed dacs such as La Voce and La Scala) but with a discrete R2R resistors ladder instead of Burr Brown PCM1704 dacs. Technology Galvanic and magnetic isolations are implemented between the FPGA and the four branches of the R2R ladder converter. This creates complete isolation of all digital circuitry - including the clock - from the analogue section for a pure clean ground plane. It also plays the main role in the differential management of the R2R ladders, achieving perfect symmetry between the counter-phase halves. The result is the highest tonal contrast and naturalness never heard before from digital sources. The Formula Dac uses no digital filter or any other compensation, relying instead on maniacal attention to each sub circuit. The analog and digital power supplies are executed purely discrete by extensive use of BJT, Mosfet, Jfet and ultra-fast diodes. Passive parts were selected not just for the best sonic result but also for their top quality, longevity and reliability. With the exception of six superior quality electrolytics, all other caps are Tantalum, solid-polymer OS-CON and double-metalized MJP. The signal path itself is direct-coupled and free of all capacitors. The two output stages (one single-ended, one transformer-coupled balanced) use discrete BJT and JFet with metal-film resistors. All the electronics parts show an ultra low RF noise.

    Possible. I think it’s a config issue. It isn’t the most straightforward software to config.

    The Dynaudio units sound better for sure.

    Article: Audio Engineering Matters, Not The Format

    Take a step back and please think about the difference between the delivery format and what happens as part of the playback process. We must separate the file format or music format (PCM/DSD) from what happens “inside” the DAC. Many DACs oversample to 768kHz internally. This shouldn’t be a call to find 768kHz recordings because they must be better.

    Dynamic Range Compression Equivalent In Video

    Hi Guys - I know video has dynamic range, but I'm trying to figure out if there is an equivalent to audio dynamic range compression in video. This may help people realize the damage done to compressed audio, if they could see an equivalent process done to video. Ideally, I could compress the dynamic range of video as much as some audio, and it would be super dark or super light etc... Anyone?

    Exactly. Two very different things.

    The new Eric Clapton Christmas album is stellar.

    Article: Audio Engineering Matters, Not The Format

    Hi Shadorne - I think you’re conflating format and what happens as part of the conversion / playback process. Resampling / upsampling / oversampling etc... are very different from the format in which the audio is created or stored. If 44.1 kHz is enough for some people, it doesn’t mean there aren’t gains to be had by changing this before conversion. Perhaps @Miska can add to this conversation.

    Blind Results Surprising But Not Really

    Hi Guys - I couldn’t help but notice the parallels between this blind camera test and listening to music. I don’t want to give away the results, so I won’t say anymore. Once you see how this turns out, you’ll likely see what I’m talking about.

    Thanks for the feedback. Do note that it’s on the top of every page under the thread title, but I agree that’s not as nice.

    Thanks. There is a better fix on the way to resolve this. It has to do with the amount of memory available on mobile browsers and how it’s used. Thanks for for your patience.
