It's a good question, and as the music industry struggles to rediscover a reliable revenue stream in the shadow of declining year over year CD sales, playback technology continues to advance at a break-neck pace. There's even evidence from the first half of 2016 that the resurgence of vinyl slowing down, as are digital downloads. All of this points to one thing...the general population, including many audiophiles, is losing interest in owning music (physical media and downloads) in favor of renting. This change in attitude towards music ownership dovetails nicely with the music industry's shift towards monetizing music consumption through licensed streaming services that are ad and/or subscription supported. Music subscription services are nothing new, but over the last few years, typical stream quality has increased from 64 or 96kbps to 256 or 320kbps, with a few services like TIDAL HiFi, Deezer Elite, and Qobuz even offering streams with lossless compression. DSD live streaming is available in Japan, and Meridian is telling us that MQA streaming is just around the corner. We may have video streaming services like Netflix, Hulu, Youtube, and others to thank for the increase in both demand and supply of faster Internet speeds. Uncompressed/lossless 16-bit, 44.1kHz or even higher resolution audio requires a small fraction of the bandwidth demanded by HD and 4k video streams. While these speeds have not made it to every rural area in the US, Internet bandwidth at home that's sufficient for reliable 16-bit, 44.1kHz audio streaming with lossless compression is common if not universal. The question that a modern audiophile might ask is, "When will streaming come of age and merit serious consideration as a viable first-class source in a high-performance playback system?" I submit that this time is just around the corner for most of us and is already here for early adopters. Within the next 5-10 years, I predict that virtually all of us will be doing both critical and enjoyment listening via audiophile streaming services nearly as often as via physical media and purchased downloads. Most of us will hang on to our physical media since nothing can take away the joy of ownership or the fun of collecting rare out-of-print pressings and limited edition masters. But the bulk of music discovery and playback hours will, for most of us, gradually shift towards streaming as the sound quality matches or possibly exceeds what we have become accustomed to from CD playback. You might be wondering, "How in the world can the sound quality of streaming audio ever exceed that of spinning a physical CD?" Another good question, and ignoring the possible future of high-rez PCM, DSD, and MQA streaming for a moment, the answer may have to do with memory-based digital transports vs. real-time playback and the associated vibrations and errors due to spinning a plastic disc at 200-500 RPM. Playing digital music from RAM is a completely silent and vibration free process that's virtually if not entirely error-free. The technology required to shuttle that bitstream from the media player's memory to an external (typically USB) DAC has also matured dramatically in the last few years, minimizing or eliminating the deleterious effects of jitter and transport borne electrical noise. Assuming exactly the same master content on the streaming service, a high-quality memory-based media player can now finally outperform the most elaborate CD transports and players from years ago. If you're still with me, I've just asserted that the sound quality of playback from Internet streaming services like TIDAL can match or exceed that of spinning CDs in your big rig! What??! That's right. But just like anything else in high-performance playback, it takes some work to get there. Running that awesome Morrow MA2-POD REFERENCE cable from the headphone jack of your iPhone or laptop to the back of your Audio Research LS28 is not likely to result in audio bliss. Since this post is already getting rather long, I'll stop here and share more details for anyone who is still interested later. In the meantime, feel free to share your thoughts or post questions in this thread.
