Combat Pretzel posted:Someone had an early sample and did some simple tests, and the results looked interesting. As said before, no crosstalk, and ostensibly the frequency response is as near to a flat line as can be (no dips at the low end and nearly nothing at the high end). Still gotta wait for proper RMAA results whenever that card gets sent to reviews in larger numbers. http://nwavguy.blogspot.sg/search?q=RMAA According our favorite missing in action audio mythbuster nwavguy RMAA is a worthless testing tool, and crosstalk performance is bottlenecked by the 3.5mm jack itself.

Panty Saluter posted:Is that a feature of sharing a ground connection or just the physical closeness of the jack? It's going to be a bunch of things. Anywhere there's close wires in parallel, you're going to have some kind of crosstalk. The plug itself doesn't even put the ground between the left and right channels. Then... who knows what the wires look like leading to and from the jack. Someone's gotta offer headphones with twisted pairs for the individual headphone channels... If they don't, you just found your license to print money with audiophiles. Now the real question is, is there more crosstalk from audio passing through your melon, than -80db from the amp, and cabling.

Stereo music almost never has a sound in one ear only anyway. Unless something is broken chasing down crosstalk has to be one of the worst ways to get better sound.

You could also make claims (legitimate ones) that twisted pair prevents outside electromagnetic fiels from introducing signals into your crystal clean audio. :-) Edit: Twist one cable one way, the other the other way. To "cancel out soundstage differences".

synthetik posted:Aren't the twisted pairs in a CAT5/6 cable actually twisted in specifically different lengths to achieve this very thing? I swear I remember reading about that in some class a lifetime ago. Each direct pair of wires, that is each pair where one carries a signal and is matched up with a wire carrying the exact opposite (you do this to make for a larger total signal over long ranges without having to use a lot of power) is twisted together at the same rate. Each successive pair is twisted at different lengths in order that pairs won't pick up on the same noise in the same way as another pair. This is the most common pattern of standard twistings, but there's no particular reason you need to use that specific thing, so long as you make the twists stay out of sync between pairs reliably. You're also allowed by standards to not even bother to twist the pairs for something like up to 10 meters at once, to meet needs like flat cables or simply cheaper cables, though obviously those cables will be more sensitive to local noise:

Bonus points when their specialty audiophile grade gear actually performs even worse than the unclean mass market "crap" they loathe so much.

McIntosh announced an integrated amp with what I'd assume is a teeny bit of overkill on the D/A side:quote:a built-in 32-bit DAC, and a DA1 Digital Audio Module with USB input that can support DSD256 and DXD 384kHz files.

It also alters the tone of the speaker amp combo. If it was described to an audiophile that way they'd probably heave, mind. quote:Power Guard® that monitors and adjusts the sound wave at the speed of light to prevent harsh sounding distortion and clipping that could damage your speakers I love marketing departments - so that'll be an optical compressor, then: http://www.uaudio.com/blog/la-2a-analog-obsession/

If they did it the right way they might actually have to spend money on the construction, which would eat into their million percent profit marigin.

(the 5532 being the opamp which actually drives the headphones)

Is there ever a reason to use tubes other than for audiophoolery or "it looks cool"? I can at least respect the latter reason.

grack posted:Come on, there are plenty of reasons to use tubes! However, just about all of them are along the lines of "you are a manufacturer and want to charge more money than is reasonable". Honestly, fishmech's comment was correct. Idiots choose to "color" the sound their headphones produce, rather than have them produce an output as flat and close as possible to the original recording. So manufacturers build tube amps which literally add distortion to the audio signal, and imbeciles will then spend hundreds or thousands of dollars on them instead of a perfectly capable solid-state device (that adds no distortion) so that they can post smugly about their "warm" or "tubey" sound signature on Head-Fi.

So it's basically the same reason some people think vinyl sounds better than formats which are technically truer to the source, because the RIAA equalizer curve plus the natural distortion of the medium gives it a distinctive sound.

If it sounds so great, people can just run a DSP, or the producers do it for them on the source material.
