Based on what Eric said, a cable that is compatible with HD 560S ought to also be compatible with HD 620S. I've been happy with every cable I got from Lunashops, but I haven't used their HD 560S cables, and I certainly can't say it will fit an HD 620S. If you want to wait to find out, then I can...

There are 64 steps in the volume control. I believe this is 1.25 dB per step, and that's what it sounds like listening to it. The steps are small, but definitely noticeable. You might want to play around with a software volume control set up for 1.25 dB steps to make sure it'll work for you...

I've just resigned myself to the state of affairs with earpads. It seems like most people actually are happy with imitation leather and velour and so on. For the most part, third-party pad makers will have something I'll like for a popular enough model, but they'll have to see demand for it and...

You do also get a remote control and NOS mode, but, then, those things haven't been enough to convince me to get the chassis upgrade either.

One of the most useful parts of his reviews is measuring frequency response with a sequence of different amplifier output impedances. Much more helpful than having a single nominal impedance number to use with the 1:8 guideline, you can actually see how amplifier output impedance affects the...

I lower the dust cover. I have some little Sorbothane triangles that help to isolate the dust cover from the plinth. After that, I can't hear it even at low speaker volume.

Linux was not a public-sector project and has mainly been developed by contributions from private organizations. For a standard that originated in the public sector, the STIGs come to mind, but the corresponding CIS standards are at least as popular.

Is the hum in the signal, or is the transformer vibrating?

My experience is that having a cheap motor on the same circuit (which could be far away) is much worse than merely having the motor near a device.

It's surprising to me to hear that there are music playback protocols using UDP. Latency is certainly very important for gaming, and it matters for video playback at least to the point that you can control synchronization by delaying the video to match the audio. But for simply listening to an...

I ordered a pair of RS2Xs a few weeks ago, because I really wanted to try a pair of wood Grados, preferring one of the models that people say has more bass. I was certain this would cause a pair of GH2s offered to ship from the US to appear on the classifieds in short order. Of course, it did...

Something I've been wondering about is the impact of thermal cycle count on a vacuum tube filament, as opposed to tube operating hours. My thinking is that with a normal incandescent lamp, there's an estimated lifespan in hours, but we can also dramatically shorten the total number of operating...

It might look a little silly with a transformer sticking out the top of the case, sure... but it's not like you can stack anything on top of it already, because of the tubes. Or maybe it's too big in the wrong dimensions.

My system has a Bifrost 2 plugged in through a Saga S, and one of the Saga S outputs goes to some powered monitors. The difference between active and passive modes in my system is mainly just that the active mode is louder. The Sys will probably sound perfectly fine in your system. Since it's...

That note might be about the de-glitching change they did early on.

This is normal for any Schiit DAC. The device exposes to the operating system that it has no volume control. It works the same way on Windows or Linux. Pre-Unison Schiit DACs are the same way and it's not specific to Unison. They're just designed so that you will put some sort of volume control...

More convincing cymbals is the main thing I like about the sound of Schiit multibit DACs over typical delta-sigma DACs. I think it's a bit better with Yggdrasil OG, but Bifrost 2 has the same thing going on, as I hear it. The Bifrost 2 really does shrug off a lot of sources of noise that will...

It's in development: I linked this with the right timestamp, but it seems like the video embedder doesn't pick that up quite right. Start at 00:33:45.

The approach that I take, personally, is that filters are the cure for a bad signal, but not for a bad transducer. I will use equalization to fix the recording and not to fix the playback system. If I can process something offline, destructively, in a digital editor, then an FIR filter is great...

Frequency-dependent phase shift is, in general, inherent to real-time filtering and analog LC filters like those in Schiit EQs will introduce it just the same as digital. If you absolutely must use filters and absolutely must avoid any phase shift, then the most practical way to do that is with...

Roger Moore was the best Bond.

Yes, just hold down the input selection button for about three seconds and then release it. The LED for the selected input will be on continuously when the digital filter is enabled, and it will slowly fade on and off when in NOS mode.

People will tell you something to the effect that it's pretty much the same thing, which is true. The idea was that they ought to be similar enough that you could use the same chips to implement an interface for either one. There are some differences in the data, and the physical connections are...

It is. S/PDIF can be carried electrically, using the 75 ohm coax cable, or optically, using a TOSLINK cable. In one sense, S/PDIF is the data carried in the signal, which could be transmitted in different ways. But S/PDIF also defines those two physical connections (75 ohm coax or optical...

I don't think it's a "strong view" so much as a basic expectation. The data stream on the disc itself is a single continuous PCM signal, and the track divisions only exist in metadata recorded in the table of contents. If the player is producing one or more samples of silence between each track...
