  1. Agreed. With more than 1,600 LPs transcribed to digital format I can play family favorites like Meade Lux Lewis & Louis Bellson - Boogie Woogie Piano and Drums anytime I like.
  2. I’m glad to see that we now all agree on one thing. An LP digitally recorded with a better than decent turntable, cartridge and phono stage and properly mastered to 24/96 or better will sound identical to the original LP. We can now all get a well deserved and good night’s sleep. All kidding aside, thanks to all for contributing to this thread. I’ve learned a lot about something that I thought I knew about.
  3. Except when it's set for resistance and you connect across a power circuit. The digital meter will go beep beep beep to give you a warning. The analog meter will blow up in your hands. I speak from experience.
  4. I'm (originally) an Industrial Electrician by trade and went from an analog meter to the first Fluke digital way back in 1978 or so, and have been using one ever since. I'm using a Fluke 189 right now and also have an older Fluke ScopeMeter that still works well. These days I'm more involved in machine design and R&D, but always have a meter handy. It can be a dangerous thing - one of the things we teach people starting with a multimeter is that, at least for signal level work there's no point taking a reading if you don't know what it should be. For most electrical work, people are looking for voltage/no voltage and that's a lot more straightforward. Two things to watch for - Auto Ranging and AC/DC selection. With auto ranging, a handy function, I was fooled checking SCR gating on a 480 VAC circuit where I had a reading of 420 or so, which didn't make sense. In fact, the reading was millivolts and just picking up stray voltage, a "ghost" as it were. Watch the units for ranging or set it manually. With AC or DC selection you can easily get killed. The example we use (in Canada) is what do you read when you connect your meter, set for DC, to a 600 VAC three phase circuit? You read zero volts, because there is no DC. But, oh boy, is there ever a voltage there. I've had so many people over the years watching me troubleshoot complex industrial machines say to me "Hey, can you take a few minutes and show me how to use one of those?" You have to be rude and say, "Get your journeyman's and come back in four years, then we can talk."
  5. Not that anyone is really interested, but in the interest of closing off this topic I believe I may have found a solution. I installed my V-Link 192 USB/SPDIF converter. I've had the V-Link for some time, where I used to test against the very issue I'm having now, loss of soundstage with a direct USB connection to a DAC. The test setup is this, identical 2 TB external drives are connected to a laptop running JRiver and to a Bryston BDP-2 that I connect to with a web page. The SPDIF from the converter and AES/EBU from the Bryston are connected to the inputs of the PS Audio DSJ DAC. Fortunately, the DAC will automatically switch to the live input. I can control JRiver from my iPad with JRemote, and the Bryston with the web page or with an application called Soundirok which gives better volume control. Mind you, for this test the files are played at 100%, I can control volume with the integrated amplifier remote. I cued up a number of high resolution titles, a couple from Dire Straits Brothers In Arms (MOFI 45 RPM), Los Lobos Light of the Moon (MOFI) and Dave Brubeck Take Five (Reissue). Interestingly, the V-Link connection is slightly but very noticeably superior to the Bryston player. There's more depth around the midrange, and light and quick sounds from piano notes or acoustic guitar tend to be more solid, more lifelike where with the Bryston there's a bit of shimmer or splash to it. It looks like playback from the laptop with not only the converter but that in combination with the new DAC presents more of a noise-free signal to the DAC, and that difference can definitely be heard.
  6. I’m glad to hear that. And now I can cancel my trip to Niagara Falls with my pickle barrel. All kidding aside, I have a minimum of five copies of digitized music on drives in at least four different places. I don’t trust anybody with my music or my data.
  7. Of course! But they are what they are and I just haven’t seen the need to make a change. It ain’t broke......
  8. I don’t expect you to follow my very few posts. I started a thread with loss of soundstage using PC playback as compared to, in this case, a Bryston digital player. The latest DAC, about a week ago is a PS Audio DSJ. Testing with the same setup, JRiver with USB or Bryston BDP with AES/EBU still gives a slight edge to not using a laptop, at least in my setup. This is with 24/192 files recorded on my system from MOFI albums to a Korg MR-2000S. I would need more from you than a “why not try it out” for me to consider comparing one digital file to another. Bit depth, sure. Sampling frequency, yeah. Digital file type? Can’t really say.
  9. Yes, that was my point. If one digitL file, other than embedded metadata has a supposed advantage then I can simply do that. It’ll take a couple of days to run, but I can do that after I retire.
  10. Blue herrings aside, I’m a bit confused about your comment regarding FLAC files and compression. I see you’re a proponent of AIFF, and that’s fine by me. But, what do you suppose could ever occur that would cause a lossless compressed FLAC file to lose any resolution? You generally present a sound argument, but with this I just don’t get your point. I have about 1,000 CDs (16/14.4 obviously) and over 1,500 LPs (24/96) all in FLAC format all compressed to the default level 5. If AIFF has any particular advantage, then I can simply do a batch convert to that format? Historically, the issue was not only with storage but also with processor speed and resources to decompress. Now that neither is really an issue anymore, these types of comments don’t seem to have any relevance. Oh, and cloud storage? The day I trust my 2 TB of lovingly recorded and painstakingly mastered music to some here-today gone-tomorrow bunch of servers in some dingy basement is the day that I go over Niagara Falls in a pickel barrel.
  11. David, You didn't mention what type of music you own now other than your subscriptions for streaming services and that might help us point you in a different direction. For example, if you had hundreds or thousands of CDs or LPs that you wanted to rip and then store, you would need the hardware to do that as well as playback.
  12. As an update, I've replaced the Bryston BDA-2 with a PS Audio Directstream Jr. I can duplicate any test with the test files I recorded the first time around from LPs. I installed the PS Audio DSJ using their USB drivers and JRiver ASIO out to the USB port of the DAC. The other connection is with AES/EBU from the Bryston BDP-2 to the DAC. Fortunately, the DAC with switch inputs automagically based on what's playing so that I can quickly switch from one to the other. You know, it was close - very close. With the updated USB drivers to the PS Audio DAC the sound was over 90% of the soundstage developed from the BDP. I was pleasantly surprised, and can only presume that it isn't just USB, but likely a combination of factors, not the least being I'm still using a Dell laptop. I had another test that I could have done but didn't and may some day. I have a Musical Fidelity V-Link 192 that I could install and have that output with SPDIF to the DAC rather than USB. But for now I'll go with the existing configuration. I didn't bother setting up Roon and a network configuration because I have no interest (at this point) of investing in an NAS. Playback for testing was from two identical USB 2 TB drives that hold copies of the master music library. I ended up staying with the Bryston player - it's a great unit and I don't have to invest any more in the stereo - at least not now. I have deleted the test files from DropBox that were linked in my first post. I don't think anyone was really interested in my foolish little science experiment anyway.
  13. K man. I don’t remember you saying it the first time but if you want to repeat then I’m fine with that. I was simply commenting on an article that has been less than well received in the audio community as having little validity. Mastering has nothing to do with anything if the source isn’t usable or credible. Beethoven can’t make a kazoo sound good.
  14. If you do, in fact, read that article it's light on technical accuracy and big on supporting the author's claims that high resolution can't be heard. I, and others, strongly disagree.
  15. Oh, I don't dispute what you're saying or question the compromise solution of alignment on a radial tonearm. My point was a properly aligned tonearm and cartridge should not have audible differences from lead-in to runout. Measurable, certainly, but audible? That's what I meant by it must be a poorly setup turntable.
