| Time clock sync devices You'll likely get more value passing your streaming digital through a clock than the output of a high quality transport like the CEC. That's why many standalone clocks are network cable in & USB out Your Transport also has their proprietary ... | |
| Thiel Owners Thanks for all the information you share here, Tom! Just to get on the right side of Thiele & Small, the term "critically damped" refers to a total system Q of .5, and "maximally flat" refers to the more commonly used .707 Butterworth configu... | |
| Thiel Owners I saw the recent references to the 03/03a Thiels, and had a question. I have a pair of 03a speakers, which came to me without the equalizer. My understanding is that they only provide a bass boost to lower the -3db point. Would anyone know what... | |
| Class A or Class D solid-state amplifiers (modern designs) @atmasphere My comment was about amp history. I don't know when the cascode amp paper was written, but the Threshold CAS-1 & CAS-2 amps date from the early 80s. I don't know the history of class D amps, but am not surprised a paper likely ... | |
| Best double live vinyl? The Band - Rock of Ages and The Last Waltz (ok, it's a triple) Mountain Jam was originally released on the Allman Brother's next album (another double) Eat a Peach. Another great Joni live double - Miles of Aisles Likewise for Jaco (as part of ... | |
| Class A or Class D solid-state amplifiers (modern designs) @atmasphere "Lowering distortion in power circuits without compromising their transient response remains a primary problem for designers of audio power amplifiers. Until fairly recently, the favorite technique for removing distortion components i... | |
| Speakers: Anything really new under the sun? The first commercially available speaker using DSP came out in 1991. Change in the speaker industry over the last 20 years has been more evolutionary than revolutionary. However, the pace has increased due to increased capacity for modelling and... | |
| Amir and Blind Testing @noske FWIW, I have a great deal of respect for scientists - I double majored in physics and mathematics. I have no problem with the tests, but I'm glad you like the pictures! Rigorous testing is always important in technology, where the goal is... | |
| Schiit Freya + Class A in Stereophile I don't blame Steeophile for producing the Recommended Components, but they are dealing with a minefield of comparisons, approximations, and expectations in doing so. It should be read as a field guide, not a bible. Hopefully, all of us have bee... | |
| Buying used vs new speakers from a technology perspective Yes, they can become outdated, both in the sense that they no longer perform to their original specifications, and that they can be surpassed by newer technology. And yes, they will eventually require repair or go past that point. 14 years is pr... | |
| Amir and Blind Testing I believe that when Amir places an audio device on his test bench, he goes into "lab tech" mode, where sound only exists to confirm the perfection of his measurements. Seriously, improvement is a hard thing to quantify. If everybody agrees A >... | |
| Recommended integrated amplifier for upgrade I can't speak to Audio Science's possible affiliations or commercial biases. I'll be honest, though - I'm a litle biased against it. The sheer number of reviews suggest that they are really just lab tests. I did read the Topping review linked a... | |
| Class A or Class D solid-state amplifiers (modern designs) Actually, the 70s were the Spec Wars. Objectivism ruled and high negative feedback gave vanishingly low THD and IM numbers. However, the resulting sound quality got worse, not better. TIM distortion was discovered, feedback was dialed back, and... | |
| Turntable - The Next Step If you're asking what single upgrade would yield the most cost-effective benefit to SQ, I'd suggest a new cartridge. Another bang-for-bucks upgrade would be to get an LPS to replace the wall wart on your phono preamp. MS sells one that would be ... | |
| Are there speakers that disappear regardless of the recording? This is probably not what the OP is referring to, but anyone who has ever heard the Beveridge electrostatic speakers would have to answer YES. They generated a true cylindrical wavefront - you could walk anywhere in the room including around and ... |
