Has anyone found distortion measurements comparing PPS to C0G/NP0?

Good, the forum members don't need more misinformation from some IT guy who thinks he actually knows something about computer architecture.

I find this thread hillarious. DRAM bit-error rates are ridiculously low. If you aren't doing extremely high precision floating point calculations where you use the result to make a safety critical decision you don't need ECC. ECC is single-bit correction and not really all that useful, it's...

No, a lower impedance is harder to drive! Lower impedances require more current from the amp driving the load. The practical exception is where current is not a problem but voltage swing is, which only happens in a battery powered player generally.

K701 is a lot harder to drive than HD650. K701 has a 64 ohm impedance. It also is less sensitive. Volume control has to be up quite a bit higher for K701 to reach the same level as HD650 on the same amp.

Teflon is an excellent dielectric.

Yeah the higher impedance headphones are easier to drive. However, as you point out, the higher impedances need more voltage which can be problematic if you like to listen loud.

Higher impedances are, in general, always easier to drive loads. For an amplifier, as long as the sensitivity is not outrageously low, it is actually easier to drive a 300 ohm load than a 32 ohm load. HD650 is pretty good out of a portable really. One of the worst is AKG K701. It has a...

WM8740 has internal op-amps already that are most likely worse than the very good op-amps you have available externally.

If it was my design, I'd use an opamp as a differential to single ended converter with a low-pass filter. This way you can get rid of the caps and have a filter easily.

All modern audio DACs should have low-pass filtering on their outputs, keep this in mind. You might be able to get away without one but the measurements get worse and the chance that you make the amplifier oscillate go up.

Threads like this are why I almost never visit here anymore. A lot of people come here to learn and they get confused/brainwashed by charlatans like the original poster. Having been around quite a while I can pick out the good from the bad, but I feel bad for new readers who are being fed...

OPA2134 is excellent. Making sweeping statements about an op-amp without knowing anything about the circuit it is in is useless. Non surface mount ceramics probably Z5U, horrible, remove them and replace with stacked (not wound) construction metalized polypropylene or polyester. I wouldn't go...

You need a PLL + VCXO... you cannot pull a normal XO

Has anyone had an EMU1212m where one of the phases of one of the channels on the analog IO board is much quieter in volume than the others? Mine has always experienced this problem as far as I know, I just used to ignore it and use the inverse phase of both channels (I use a mono adapter so I...
