thd+n

Good morning everyone, my name is Riccardo and I am new to the forum and the world of sound systems. I have a question regarding the technical characteristics of a DAC versus those of an AMP: by comparing products of the same brand (e.g. SMSL) I noticed that the SNR and THD+N of ADCs or...

I just happended to stumble upon THD+N data @ 4 Ω for the AO200, published by Aoshida. SMSL isn't even displaying this data themselves on their AO200 page. They only show results for 8 Ω. Obviously, I can't check whether the data is correct and actually belongs to the AO200. But I thought I'd...

I just built a power amplifier module based on the Trimodal Power Amplifier by Douglas Self. This is part of building a complete integrated amplifier. I'm now working on the preamplifier, power supply, PHONO preamp, input switching, speaker protection and maybe remote control unit. For those not...

I wanted to compare amplifiers measured elsewhere to the ASR standard measurements: SINAD at 5W in 4 ohms, and power at 1% THD+N in 4 ohms. So I chose some amplifiers that interested me more (let me know if you wish I can add more), read their graphs, converted to SINAD, color coded and created...
