    Forgot Rob's recent reply to you? But the real interesting stuff is when you take a sinc function and try to meld it to suit the real life requirements of limited processing - or getting more sonic improvements from finite resources. Then it becomes very interesting indeed, with lots of careful...

    It's not a software problem though, it is still the hardware. FPGA is designed for this stuff and is fast enough. Whereas a PC is designed to run Windows and spy on you. If a PC was fast enough it could do the exact same thing. One day a phone may be fast enough and there will be an app for this...

    The example I gave was to show how it works, it wasn't in relation to the software discussion beforehand. Yes, obviously truncation must happen and window applied etc. For sinc interpolation, the longer the better though. No idea how long it would take, but I think it would be minutes per song...

    The slowness in the KH example is due to the on the fly calculation of sin(x)/x (the sinc coefficients). You can pre calculate these and store them.

    If you have an amp that does both single ended and balanced then in balanced mode you will get twice the voltage and four times the power. This is because you need to duplicate the amp again for the out of phase signal so in balanced it is using two amps (per channel). TT2 does this.

    Sankar is cool but maybe not wise to be so honest answering this after Fangs famous quote. https://www.innerfidelity.com/content/innerfidelity-podcast-no-3-audezes-sankar-thiagasamudram Listen at 14:25 Mr Speakers got it right...

    Question for Rob, Have you ever thought about also implementing the mscaler as a software computer based solution in non real time? Simple to duplicate it and you could use any number of taps, 256 million even billions. It would be very valuable as a testing tool alone. You could save as...

    It was just a rough estimate, I didn't double it for Nyquist though. It depends on the total bit rate which is not close to the 384kHz that was being discussed.

    Check out this excellent video... It's long and a bit technical but explains some of the digital magic. Keep in mind that 1 bit DSM is what Sony branded as DSD, multi bit DSM which is a lot better is no longer DSD. Also a post from Rob about different DSD rates...

    Schitt amps would be a backward step, Violectric 281 is more of a side step. The LAu is an option if you can find one, very good but is a bit too coloured for me. Forget the massdrop/monoprice ones. In the same price range, there are not that many options as the 430 is already very good. I would...

    At the end of the day all this tech talk doesn't matter, your ears will tell you which is best. Regardless what you buy it will be outdated, that's life. Don't worry about the elements too much, they run at different frequencies/implementation etc, not always comparable. Anyway, the pure 1-bit...

    You are probably just hitting a sweet spot, looking at that THD graph, for the 150 Ohm case around 1V is the lowest distortion so by adjusting the gain on the H2 you may be in that region, it could more complex than that though. This amp probably sounds tube like, it has quite high distortion...
