    New world of HiFi with Chinese Class D Amps.

    This subject seems to create lot of love and hate debate. Class D so cheap yet very good sound. The imperfect circuitry also gives the hobby a new flavour from rolling Op Amps. These small Amps now are very powerful. We have these on Dual-Mono Configuration, Bridged and Bi Amping power hungry...

    Topping D50s - 3 months in - Socketed OP Amp Swapping choices?

    Having had this a few months to play hi-res sacd/dvd-a/hd tracks, etc. files, Things I like: Really clean, clear sound and great dynamic range. Very smooth and 'glassy' as sound. Remote is fantastic, and the fact that it can decode up to dsd 512 and 768Khz pcm is great. (only have a few test...

    New Op Amps for a Music Hall DAC 25.3

    While most of the time folks talk about the converter chip itself used in a DAC, I find that much of the sound quality you actually hear is due to the analog output stage. Which is just another line stage in the pipeline. Op amp chips are clearly very cost effective with even the most...

    Op Amp Book

    I'm looking for a good primer on op amps. Ideally a little theory, a little practical circuit design and building. Something between a heavy duty textbook and just a bunch of paint-by-numbers circuits. I have a decent, general, self-taught electronics background. There are lots of choices out...
