    Yes. I bought the book on that account.

    The Truth About HiFi Amplifier Power Supplies

    Actually the 'diode noise' is a product of the power transformer. To snub it, a capacitor in series with a resistor can be placed across the output of the transformer at the rectifier input. Because its more of a transformer issue, its best to keep the transformer leads as short as possible...

    Can anyone explain the vinyl renaissance?

    That might have been the case of kiddie LPs. Certainly not for something like the Soria box of Verdi's Requiem. That one has little compression and can easily bring a limited system to its knees if you try to play it at a realistic level. The main use of compression on the LP format, as I've...

    Stereophile's Jim Austin disagrees w Atkinson; says tubes have something that can't be measured

    Much easier to work on, but also need to be worked on far more often. Really pretty, but inefficient, unreliable and lucky to make it 100K without an engine rebuild at the very least. Not safe in a crash and more likely to have one because they could go much faster down the road without...

    Stereophile's Jim Austin disagrees w Atkinson; says tubes have something that can't be measured

    I'm very convinced that the last thing the industry wants is a market where they could tell from the measurements what something actually sounds like :D

    Can anyone explain the vinyl renaissance?

    That's easy and I'm a bit surprised you even asked! Again, if you want to denigrate LPs, there's good reason to do so, but its best to use facts rather than made-up stories and myths. RTR is easily re-recorded and spliced, and even the ancient tube tape machines were easily transported for...

    Stereophile's Jim Austin disagrees w Atkinson; says tubes have something that can't be measured

    Back in the mid 1980s most of what this hot Stereophile mess is about was true. There were things we could hear but not measure. That's changed; its peculiar that people seem to think that measurement technology hasn't advanced since then. But what has not changed is tradition- audiophiles...

    Can anyone explain the vinyl renaissance?

    This statement is false. LPs are lower distortion, lower noise, wider dynamic range and wider bandwidth than RtR. That they typically don't show that off isn't the fault of the LP so much as that of people being cheap about producing them. There are plenty of ways denigrate the LP but if you...

    Huh?? 'Sounds'? How is it on a site that is supposed to show how measurements work that we're back to the subjective experience??

    Open Baffle speakers

    You can mess with 'wings' on the side and top of the baffle. Too deep and you get a cavity well resonance but they have the advantage of being twice as effective as the flat area of a baffle in terms of LF cutoff. So you can use them as a 'stand' to hold the baffle up. There are some very...

    Can anyone explain the vinyl renaissance?

    You can eliminate most of the ticks and pops without cleaning the LP, simply with proper setup and a decent phono section. Ticks and pops show up when something's wrong.

    Can anyone explain the vinyl renaissance?

    The first land speed record over 60mph was outside of Paris, set by an EV about 1898. Edison and Ford announced an EV in 1912 that could cruise at 60mph with a 100 mile range using nickle-iron batteries. Edison's laboratory burned to the ground 2 weeks later, essentially ending his career. 1200...

    Can anyone explain the vinyl renaissance?

    Actually, the better your LP playback apparatus, the closer you find it being to digital in terms of noise floor. When you have an LP cut, you (unless being sloppy) get a test pressing back from the pressing plant. It is there for approval; you have to sign off on it. Ticks and pops are the...

    Can anyone explain the vinyl renaissance?

    We ran a mastering operation (LP Masters) for about 12 years. I've known Chad Kassem for about well over 30 years; when a client asked to have his project pressed at QRP I talked to Chad about doing it since it was a small job (he owns Acoustic Sounds and also QRP). Now what you may not know...

    Can anyone explain the vinyl renaissance?

    I'm curious why people talk this way when its not really analogous to what happens in an LP groove. You may consider the tech to be 'crippled' but it has advanced quite a lot since 1960 ;) Cartridges have gotten a lot better, putting to bed that old saw about lack of bandwidth at the inner...

    Vinyl will always sound *different* than digital, right?

    Is providing information a bad thing? If you have to pay attention to loading of a LOMC cartridge, its an indication that the phono section isn't designed to handle the RFI generated by the cartridge. The electrical peak that LOMC cartridges have has a higher Q so the peak can be up to 1000x...

    Vinyl will always sound *different* than digital, right?

    With any MM high output cartridge, its worth it to pay attention to proper loading. The inductance of the cartridge in parallel with the capacitance of the tonearm cable sets up an electrical resonance that is just ultrasonic of else in the extreme upper register of the audio band- acting like a...

    Vinyl will always sound *different* than digital, right?

    Probably. We did run white noise through the system once, just to check it after we got it all up and running. It seemed to handle it fine but we didn't push the modulation.

    Master Thread: Are measurements Everything or Nothing?

    445 pages and... I've noticed that there are audio dealerships, wherein there are audio products on display. I've also noticed that the vast majority of buyers like to go and see, either at the dealerships or audio shows. In all cases they are invited to sit and have a listen. So. As much as I...
