    Review and Measurements of Purifi 1ET400A Amplifier

    There is the option to use 2 power supplies, increasing the price from single PS £ 979 to twin PS £ 1,129 plus VAT. Case looks nicer and opamp in rev C buffer is also better, so Nord takes the crown of best cheap stereo Purifi power amp.

    Hypex nCore vs Class A amps

    Yes, I agree with you: some designers just choose not to reduce distortion as much as they can, and opt instead to "tune distortions to taste". Valves and vinyl comes to mind too. Here is the totaldac measurements. I am sure the designer has all the gear he needs and still chose to let this...

    Hypex nCore vs Class A amps

    DIY Purifi Amp builds

    I really wish that Purifi would release an "1ET1200A" module with 1200W and similar low distortion. That would make me want to upgrade my current NC500 based Apollon amp.

    Pioneer GM-D1004 4-channel Car Amplifier Review

    HIDIZS S8 USB-C Headphone Adapter Review

    Ok, after some back and forth between SMSL Idea and Hidizs S8 using the Audeze LCDi3 I hear a difference, but I would lying it I said it is huge. It is a little cleaner sounding, but that is listening to high res well recorded music and searching for differences. I don't know how I would fare to...

    SounDigital SD 600.1D Nano Car Amplifier

    Here are specs from the Alpine PDX-F4, now discontinued, but should be the same for the 4 channels of the PDX-V9, still current. PDX-F4 4/3/2 Channel Power Amplifier CEA-2006 amplifier ratings: 100W RMS x 4 [4/2 ohm @ 14.4V ≤ 0.05% THD+N] S/N ratio; 95 dB (ref: 1W into 4 ohm) This should put...

    Please do! I use an Alpine PDX-V9 every day, they should be similar. I am curious how it measures. V9 specs are promising: THD+N (10W into 4 Ohms) for CH-1/2/3/4: <0.005 % THD+N (10W into 4 Ohms) for Subwoofer: <0.006 % THD+N (Rated Power into 4 Ohms) for CH-1/2/3/4: <0.03 % THD+N (Rated...
