2019年4月22日 · SINAD for most amplifiers appear best at highest power – why they are often the only figures a manufacture's marketing dept publishes – but as long as they cover peaks without clipping, it’s the 1\2\5w percentages that matter more, because most of the time that’s what we are hearing. Keep up the good work!

2019年2月23日 · Measuring noise and SINAD of MM phono preamps properly 1. Intro It is a temptation to measure phono preamplifiers the same way as if it was a common link stage preamp, to drive it from very low generator impedance and to measure the preamp output voltage. Similar way as when measuring with AP...

2024年12月29日 · As SINAD tests only one aspect of distortion the audibility can be quite different for different SINAD performance levels. It would be nice to have a new metric that with using psycho-acoustics makes a better estimator of audibility of the distortion. Something like x dB's below the audibility threshold when played a SPL level y. Lets call it ...

2019年5月31日 · In my previous measurements, I was peaking around 122dB SINAD measurement, with a direct ADC connection Using E1DA Cosmos APU Notch, (and some lessons learned from last REW editions), I was finally able to achieve a more relevant SINAD measurement of the D90LE Measurement is done with Topping...

2022年8月15日 · Hi All, When reviewing eg the review of the Marantz SR8015 I see that Amir measured the pre amp dac section around 98 sinad while the amp section is only 85 db sinad. Isn't the weakest link the bottleneck in the chain? So if you use it as a one box solution will the amp section not dictate...

2025年1月5日 · It is, it must be noted, the only measured parameter which can be sorted by on the master index. It would be a strawman of ASR to assert that people only care about SINAD here, but surely we can accept that it is something people on here are commonly ranking by? It is a convenient single number...

2025年2月12日 · This is the updated chart with SINAD and noise results for the Openamp MM phono preamplifier with various op-amps. Noise was measured with M35X cartridge at the input. SINAD was measured from 50 ohm low noise generator and 5mV/1kHz signal. SINAD with the cartridge was calculated using the formula posted in the post #1 of this thread.

2016年2月13日 · This is a table showing the best audio DACs and the worst based on its measured distortion and noise which is expressed as "SINAD" (signal above power of distortion and noise).

2024年12月29日 · After a gazillion of tests with all kinds of distortion (including IMD,TIM,etc) I now care only about the noise part of SINAD. Seems like the old 0.1% THD limit in the pro world is legit and plenty. Something must be seriously broken or deliberately made to exceed that. I find gain structure...

2025年1月5日 · Those with super sensitive horns might want to pay a little more attention to the noise aspect. There's already plenty of talk right around here at ASR about whether chasing SINAD higher than the 80s is worthwhile, and plenty of agreement that other measurements and features take priority past that point.
