  1. I raced Formula Vee in SCCA for almost 20 years. The first Vees were like Cadillacs compared to current ones. At 6’2” with 36” arms, I had plenty of room in Formcars etc. By the time I got into FV from C sedan (1275 Cooper S), they’d already shrunk some - but I still fit into my Zink C4 once I made a custom seat to lower me and stretch me out a bit. And I was consistently in the top 10 at regional races years after most Zinks were on Medicar. As I and my Zinc aged gracefully, the average driver shrunk to fit each new design because every advance in aerodynamics & suspensio
  2. This is a classic example of bass reinforcement by proximity to reflective surfaces (boundary effect). Floor placement alone boosts omnidirectional frequencies (below 80 or so) by about 3 db. Put it on the floor and against a wall to add another 3 or so. Corner placement on a floor adds another dose. Reflected bass is close to but not perfectly phase aligned, and this is affected by exact positioning (angulation in all planes, spacing between surfaces and speakers etc). So the reinforcement makes it louder but often muddies it up. Read about it in this piece from TAS on improving your bass.
  3. Ahhh! The good old days......when the tires were skinny and the drivers were fat.
  4. Minor errors are not necessarily in the program material per se - they're simple checksum mismatches. They're also reported when any data on the CD are not identical to the same data in the reference db. This can occur because of a difference of a fraction of a second in track length between your CD and the reference, which may be as simple as the fact that your disc is from a different pressing than the one from which the reference data were derived. Remember that freedb got its data from people like us who uploaded our CDs - it was not an industry database, and neither is AccurateRip.
  5. That looks like it was part of the Black Tulip system that Philips introduced some time around 1980. I don’t remember any details because it was of no interest to me - but I think there were some decent reviews of the top line amplifier in that series. The only info I recall is that the BT system was not “budget hifi” - it was aimed at audiophiles. Although the dating and your somewhat fuzzy picture seem right, I have no way of knowing if this is part of that line. The amplifier models were numbers (300 series?) so if there’s an identifying label or mark on any component, you could try sea
  6. The disconnect here is that Amazon offers vendors a huge market from which their net revenue is potentially far greater than they could generate on their own. So it’s a simple decision - be your own person or surrender to terms and grow your business. If you surrender to their terms, the benefits have to be weighed against the costs. My latest startup was an Amazon Associate for about a year. We had their ads on our website, and several sales were generated from IP addresses clearly on the other side of the country and not connected with us. Amazon canceled our account because th
  7. Here’s a link to a post that should help you on a good ML forum. And here’s a link to the amplifier forum on the same ML Owners website.
  8. If you bought them new, you might ask the dealer for some starter ideas. I assume you heard them before buying and liked them enough to pull the trigger. If so, the amp powering them might also help you choose your own.
  9. Wow - if so, that's a monumental change from the early days! My dealer from the late '60s until he retired over 20 years later (Danby Radio in Philly) was an early Mac reseller who actually opened, burned in and checked every piece he sold to be sure it made spec - he would not sell anything in a sealed box, because he felt responsible to his customers. He actually lost a few sales because of this policy. Danby was an authorized Mac service location. I vividly remember Dan's sending a few newly arrived pieces back over the years because they didn't quite make the stated numbers
  10. I just laid up a few bottles of a wine that starts drinking well in 20 years. The snide comments from friends and family have been amusing, e.g. "Your aide can remove the cork", "The nurse can use it to clean your bed sores", and "It'll keep the feeding tube from clogging". Fortunately, I'm impervious to insult. I bought it to enjoy at my 94th birthday party! As I recall, he was a diabetic and spent a few days in what I suspect was a hypoglycemic coma. He did lose some mental acuity but apparently recovered most or all of it in rehab. He truly dodged a bullet.
  11. Peterson didn’t play a club for 4 1/2 years, and he never regained full facility in his left hand (the stroke caused left hemiplegia). Sadly, a lot of musicians and other artists have suffered similarly. Pat Martino developed total amnesia along with a host of other problems when he bled into his brain. Miraculously, he relearned his knowledge and skills even after major brain surgery and seriously debilitating treatments. Jimmy Bruno was in a coma for weeks after falling. I don’t know why he fell, but many serious falls in our age group are caused by cardiac or neurologic event
  12. For those who don’t realize it, ROCK is also only designed and supported for the NUC. It can be installed on other hardware, but there are multiple potential issues like network connectivity that make it hit or miss. It’s basically a JEOS on a Linux kernel, so it’s light and lithe. But putting it on anything other than a NUC often turns out to be more trouble than it’s worth when the alternative is the Roon Linux package on the OS already on your PC (or a good current Linux distro if there’s no modern OS on the computer you want to use).
  13. One of the biggest improvements in the Pi 4 over all prior versions is separation of the networking bus from USB. Even the 3B+ shared one among WiFi, Ethernet, and USB. And at last, the 4 has gigabit Ethernet and USB 3. WiFi is no longer as big a limiter as it was on prior Pis because it’s not sharing bandwidth with USB. USB for simultaneous file access and output to a DAC still shares a bus, which potentially affects SQ when sourcing, processing, and playing large files with some system configurations. And USB can’t adequately power both a DAC and a drive for file storage - at
  14. And 2 gigs do the job well, especially if you run zram and use a good, fast 32+ card. If you run JRiver or other graphic-heavy programs on it, 4 gigs of RAM will speed up the GUI over a 1 gig Pi. I don’t own a 2 gig Pi 4, so I haven’t compared that variant to a 1GB or a 4GB. The 4 with the current Buster OS allocates GPU space dynamically, so setting it in the conf file is no longer necessary or possible, AFAIK. I think Stefano’s got it right - NAS is the way to go. But the OP does say “standalone”, which implies storage as well. I put Minimserver on my Asustor NAS whe
  15. A Pi 4 with 4 gigs of RAM is an excellent standalone music machine, except that you can’t keep much of a music library on an SD card. I run a full instance of JRiver Media Center on a 3B+ in my development system with my music library on a NAS, and it’s excellent for SQ. The GUI is a bit sluggish compared to a full PC, as are processing tasks like initial loading of the library data. I run a Pi 4 in my living room system (SMSL SU-8, Prima Luna power amp, Focal 726 towers). It sounds great and the functional weaknesses of the 3 are gone. The JRiver GUI is fine, and processing tim
  16. Right - but I'm not the source of that information. It was in the quoted reply I got from the US SOtM distributor: Hi David, Thanks for your email. The audio USB and the two USB ports are on the same bus. The USB audio carries +5.0V(+0.5V, -0.25V) Let me know if you have any questions. Thank you, Kamal Since the point under discussion was whether their USB "audio" port carried power, the meat of the answer was that it does. As I recall, the spec for USB is 5V +/- 5% - but there seemed to be little point in clouding the is
  17. Actually, some of the greatest values in audio are found in inexpensive powered speakers. My JBL 305s list for under $200 (USD) and I got both pairs on sale for under $100 each. The same series with bigger woofers (more bass) are only a little bit more. My Edifiers cost $130 for the pair. Many excellent brands have even better speakers for well under $500 USD per pair. All of these have enough clean power to play well and loud. Sure, you can pay ten+ times this amount. But for the system sought by the OP, actives are the way to go for sound and value.
  18. Here's a rare bird for the discussion. I've loved the Abarth OT1600 since I first saw it described in a magazine article in about 1965. I've only seen one in the flesh, but the sound alone was enough to make me remember and desire it forever.
  19. Great advice! I’m also a happy Edifier owner who thinks highly of their products and their approach to customer relations. JBL also offers multiple models spanning a broad range of size & price. JBL now sells direct with a 30 day return, but I’ve only bought their speakers from authorized dealers- so I don’t know how their customer support compares. Fortunately, I’ve bought multiple items over the years and never needed to find out. Right now, I have 4 of their LSR305s set up as MC (with a Yamaha sub) and can recommend them highly too.
  20. I’ve run benchmarks on current HDs (WD Red and Seagate Iron Wolf) using tiny and huge clusters, and the difference in random read and write performance is negligible. Others have found the same thing. This project was done 8 years ago, so the discs tested were not as fast as the new ones I used a few months ago when I got my new Asustor NAS - but the results are the same as mine: “The speed differences seen in this test between the large sizes and the default size were not significant enough to recommend large sizes...I was curious to see whether there are obvious benefits to large cl
  21. It’s the file system that asks you to set allocation size when you format a drive. Modern Linux uses ext4, and the default is also 4K. You can run into mounting problems when block size is bigger than page size, and there’s no performance advantage to going above the default. So stick to the default and you’ll be fine.
  22. Allocation (or cluster) size is the minimum amount of storage space any file can occupy on a drive. Even if you add a text file with one word in it, that file will occupy one allocation unit on the drive and the unused part will remain empty. If you add a 5k file to a disk with a 4096 allocation size (a common default), that file will occupy two allocation units (wasting the empty space). Operating systems have default allocation unit sizes that are almost always the best and most practical choice. I've played with multiple settings and can't identify any performance difference a
  23. 1. I bought a ‘57 356A normal coupe in ‘66 for $400. It was the summer before my junior year in college, and I loved that car for many reasons. It felt right. It looked right. It was a blast to drive. And it needed me as much as I needed it. After 9 New England winters, it had enough rust to look “weathered” - but the pan and battery box were still solid enough to keep me and the battery from falling out. 2. I’ve been dreaming of a 275GTB4 NART spyder since I saw it on the cover of R&T (in ‘67, as I recall). The coupe is the most beautiful car I ever saw. But I love toples
  24. Thanks! I thought I had set up the questions so they could be skipped if desired. I can't check it because I voted first to make sure it works, and it won't let me submit another response from the same IP address. With 19 responses in already, changing the questions now will invalidate those already submitted. Major security concerns are an issue for cloud based services like Alexa and Siri, and for IoT devices. But if VC is only accessing a LAN / WLAN and it's limited to audio devices on that network, I'm not seeing much potential for network access. I'd love to know about po
  25. Interesting - the responses I've seen on Google's Chromecast help page say this: "Wired connection is only available to Chromecast Ultra". But I just looked at the Google Chromecast ethernet adapter page again, and it now says that it works with CCA too. This is progress that I frankly never expected, once CCA was discontinued. The Google adapter is only $15, but I assume it has their standard USB PS inside - and whether this affects SQ is a little controversial. It's "only" 10/100 Mbps (man, how soon we forget what an advance 100 was!). This is plenty of bandwidth for high res audio fro
