  1. I see no reason to duplicate a large library when it's readily accessible where it lives. I stream my files from our home to wherever we happen to be (as long as there's internet access) with JRiver Media Center. There's a web server built into it that's accessible using an alphanumeric access key unique to each instance. My main JRMC instance is on my Win10 PC, and I use that access key for my own WAN access. I also run an instance on a Raspberry Pi so my son can listen to my files wherever he is, using his own access key. Before I adopted JRiver, I used Foobar2000 for this. With the foo
  2. I could be wrong. But his statement that he "...wouldn't be able to play [FLACs] on iPhones" suggests to me that he believes there's simply no way to do so with any player. I hope that the advantages of FLAC over AIFF might move him from iTunes to a more versatile player. For example, VLC is a wonderful player for all file types on all platforms. Paid apps like Golden Ear & FLAC Player are also great. And he can use programs like Foobar2000 or JRiver Media Center to stream his FLACs from a home computer to his iPhone over the internet, so he won't even have to load them all
  3. You can play FLACs on any iPhone or iPad running iOS 11 (2017) or later. I think FLAC is a more usable and versatile format than AIFF. It's now supported by Apple / Mac, Android, and Windows. FLACs are significantly smaller files than the same material ripped to AIFF because FLACs are compressed and AIFFs are not. Some believe that AIFF sounds better, although most (including me) do not agree - each should become an identical PCM bitstream when played with proper software. One potentially important caveat you'll read about is that FLACs are said to degrade in SQ if edited aft
  4. I misinterpreted a critical piece of information because of one of your posts, Kal - You say clearly in this quote that the Marantz will output an Auro-2D 5.1 or 7.1 signal "to your...speaker setup". It can't do that without an amplifier, which led me (and perhaps others) to believe that the Marantz units in question are receivers. I just looked at their specs, and they're clearly not receivers - they're (as you described them) "pre-pros". Forgive me for not knowing this, but my series is focused on the value oriented audiophile. A $4k+ HT preamp is not commonly thoug
  5. So the internal MC DSP simulations and ambience synthesis functions like Dolby are also non-functional on the analog MC inputs? The only reason I can see for this would be the assumption that any and all DSP is being applied ahead of a DAC in a front end that has no analog power output stage. If so, why would anyone buy (or, for that matter, try to sell) a $4k+ receiver to use as an analog amplifier in lieu of better amplifiers for the same money? You seem to be contradicting yourself with the statement that “[t]his Marantz does not do this nor does mine. There is no a/d
  6. As I said above, “If you're doing it because you prefer the SQ of the BC's integral DAC to that of the Marantz DACs, you'll negate that by adding Marantz A-D and D-A processing on top of a signal that's already been converted to analog by the Bel Canto”. That’s obviously also true for the Okto. Almost all HT receivers convert analog input to digital before it reaches the DSP chips. They then run the processed digital signals through a DAC for analog output to the speakers. So if the OP prefers the SQ of his Okto or his Bel Canto to the internal DACs in the Marantz, he’s a
  7. I'm not sure why you use the analog inputs when your Bel Canto has optical and coax outputs (assuming it's like other BCs I've seen). If you're doing it because you prefer the SQ of the BC's integral DAC to that of the Marantz DACs, you'll negate that by adding Marantz A-D and D-A processing on top of a signal that's already been converted to analog by the Bel Canto. Auro may not be accessible by digital input. But I've not seen a MC receiver that wouldn't apply Dolby & other more common internal MC processing to digital input, since most MC receivers are bought for HT and m
  8. It’s all in your point of view, Kal. You also got great electronics “free” in that Marantz - but the case and controls cost about $4500. The AuroMatic 2D plugin is $669 right now at Dale Audio and €595 direct from Auro. The 3D plugin is €1195 (~1400 USD) from Auro. This is a bit rich for people with Raspberry Pi streamers 😗
  9. I'm with you on that philosophy. For my "off duty" listening, my music server is Roon ROCK on a NUC and my main players are Pi 4s with Bridge. The living room Pi drives an SMSL SU-8 into a Prima Luna power amp and Focal 726 towers. The den Pi drives an iFi DSD Nano into a pair of JBL 305LSRs or my AKG 701QJs. Every other room has a Chromecast Audio driving inexpensive powered speakers via optical, except for the water-resistant JBL in my bathroom that only has an analog input. I also run JRiver Media Center on each Pi, on my Linux DAW/media box, and on my workhorse Win10 PC.
  10. As I recall, the AuroMatic 2D plugin lists for $600 per the B&H website. I was hoping to find a less costly way to try this, but I’ve not found one yet. If you succeed, please post about what you found. Thx!
  11. Just to clarify: you need an analog output channel for each channel in your chosen audio output format. A complete channel includes hardware conversion of the digital signal to analog, plus amplification and a speaker. Conversion can occur in a DAC at the beginning of the chain or integrated into an amplification stage further downstream. With traditional analog amplification, digital conversion to analog happens at line level (in the DAC) before input into the first analog stage. If you use digital amplification, the conversion from digital to analog happens at or near the last s
  12. Downward sub drivers are no more or less of a problem in an apartment than side or front. Frequencies below 80 or so are not directional - the source location is transparent. And the wavelength of low notes is so long that people two+ floors away will hear it louder than you will, if the building construction allows. A 20 Hz tone has a 56+ foot wavelength, and this will extend to higher and lower floors as well as adjacent apartments.
  13. Thanks!! You don't need an Octo or an spdif HAT to play MC through your Yamaha receiver - HDMI from the Pi is fine. As I recall, your Yamaha has the same (or similar) 24/192 DAC chips as my Pioneer and should sound fine through decent speakers. The Octo is a nice device, but it sounds no better than my Elite receiver. Assuming you have MC source files at or below 24/192 and/or your player will reformat your 2 channel files to MC, you don't need to add any additional hardware or software. Timing and balance problems do not exist when cabling the Octo to analog endpoints. The onl
  14. I don’t have that hardware,so I haven’t done this myself & can’t confirm for you. Today’s a holiday for me, so I’ll look into it on Monday & let you know. Stay safe!
  15. You can add hard controls for volume onto GPIO pins. Use GPIOzero to configure the pins for physical switching. Here’s a link to introduce you to gpiozero. Here’s a link to the documentation for using it. You should also be familiar with the pigpio library, another Python library for such use.
  16. CORRECTION: I meant the strings, not the keyboard. The keyboard is parallel to the audience’s line of sight and the strings are perpendicular to it. So high and low strings are all in the same left-right location. The high strings are shorter than the lows, so their centers of vibration are inches closer to the keyboard side in a grand (because the strings are horizontal). In a console (“upright”, spinet, etc), the strings are vertical. In neither is the location of the strings audible, except perhaps to the pianist. Sorry !
  17. I don’t know exactly how the processing of 2 channel source material to MC output is done. But it’s done well by both proprietary programs like JRMC and Roon and by many open source players. So you don’t have to look far or spend money to add this function to your computer. You might want to review my article on front end audio software to find one for your computer - here’s the summary table, which you can search for “MC” to find those that do it. I’m particularly pleased with HDMI for audio. Driving good electronics, I believe it’s the equal of USB and coax for SQ. Sadly, I d
  18. So I suppose now we have to stop dissing Muzak and thank it for the concept of ceiling speakers...... 😝
  19. THE VALUE PROPOSITION IN COMPUTER AUDIO Entering Multichannel at the Ground Floor “Mommy, where does stereo come from?” Every audiophile should start each day with a thank-you to Harvey Fletcher and his dummy (whose name was Oscar and who had a microphone in each ear). Fletcher is widely known as the father of stereophonic sound. He first described what he called “auditory perspective” in sound in the early 1930s, later coining the term “stereo”. He won a posthumous Grammy in 2016 for his technical contributions to the recording arts. It was
  20. I believe the goal is most often to provide a recording that will sound "real" when played back. Unfortunately, that's an elusive goal, and many widely differing standards are used to decide how close to that goal a given recording comes. Ping-pong stereo and use of spatial effects that are never part of a live performance are there to dazzle the plebes and techies. But they have no place in the recording and reproduction of live music meant to sound as it was created. Directionality is pretty much lost at any concert using sound reinforcement, which covers the Dead and most othe

  22. Many came out of that mold 😚 After 48 years of daily education, my wife still tells everyone that I’ve made it so hard to turn on and use any electronics that she can’t do it by herself (fact checked as untrue by me). So over the last year, we’ve ended up with an Echo Dot in almost every room. The first time she asked Alexa to play music, she was like a little kid with a new toy. But she still chokes on the syntax needed to activate functions, and little Al only knows exactly what she knows. Once the skills are mastered, Alexa works great. House Band lets her control J
  23. Your Rokits are pretty nice monitors - we use KRKs for all system monitoring (recording, live streaming etc) at the club in which I'm the house band leader because they're smooth, accurate, and easy to listen to all day long. I'm a lifelong LS3/5a lover with a pair of 15 ohm Rogers that I bought new the year they came out - so I do love KEF's approach to SQ in small boxes. The LS50 is a wonderful little speaker, but I don't think it's worth the marginal cost over your KRKs compared to the Elacs or the Focals. To improve significantly, I think you'd have to move up to something like the Elac
