I've never seen a switch like he's talking about, maybe he can post an example? The only thing I can think of is like a source selector where position 3 is position 1 plus position 2, then that layout makes sense from both a use standpoint and probably a wiring one.

Most of my DJ mixers inputs are like that, left is phono 1, middle is line 1, right is phono 3, but that's more of a design choice for doing tricks rather than a necessity.

You should just be able to use whatever input you didn't use on that little amp and connect that to the primary input of the system that the sub was a part of, be it on the sub or a box attached to it. Because you have no speakers attached to that system anymore, all you should get is the noises that would have come out of the sub. I did this for years with a Logitech z something 5.1 sub.

The two inputs are in parallel on the lepai so they are both effectively in/out, it would be the same as using a Y splitter off the DAC, but you don't need the Y splitter. Because both connected things, the lepai, and your sub, are powered, you don't really have to worry about impedance matching-- the loads are so tiny because they're inputs to amplifiers.

Was just flicking through youtube watching a video on redlining mixers and how it fucks your signal path (obviously). Then in the related videos found a video on about digital cables where the dude was like "if you pay X amount on digital thinking it'll make a difference, you're mad" and in the comments:

quote:

Several others have picked up on this also, what you've missed when it comes to digital cables is that you're not trying to maintain the actual data being passed. You're aim is to lower resistance so that data gets to its destination as fast as possible. Poor cables can give noticeable lag which is a bastard for sound cards. That's where the value comes in.

So let's see exactly how little sense that guy is making.

The speed of light is approximately 300,000,000 meters per second. According to wikipedia, the speed of electricity in consumer devices can be anywhere from 50% to 99% of the speed of light, so let's say the worst-case scenario is 150,000,000 meters per second.

That's roughly 15-30 centimeters per nanosecond.

In other words, the signal traveling down a 2 meter long cable will be delayed between 6.6 and 13.2 nanoseconds.

So either cheap cable manufacturers have somehow invented an electricity delay line in the shape of inexpensive copper wiring, and are selling this wonder of technology for next to nothing, or that guy is making literally no sense at all.

Either that or they're somehow extrapolating the idea that you have to adjust relative delay for multi-speaker setups with varying distances to the listener and assume the speed of sound "in cables" is the same as in air? You know, the kind of interpretation that "feels" right and smart if you're totally ignorant.

Well I received the second set of ElFidelity SATA filters yesterday. Installed in my other music server - this time without changing the PS (this unit already had a nice fanless PS unit). These things are blowing me away! The added air, transparency, bass depth is excellent - immediately noticeable. I mean a major step forward - sound stage wider and deeper. I'm truly shocked - how $40 worth of these could have such an effect. I have three HDs in this machine, one had a SotM filter the other none. I only added two of the ElFidelities, as that's what I had ordered. I'll order another to replace the SotM SATA and a couple of the fan filters to replace the SotM's already installed.

I have two empty RAM slots so will order a couple of those filters and a PCI-E board as well.

I'm sold on these

2/6 (iMac -> Minidisc -> Sansui amp -> Mordaunt Short midsize speakers). I think the test mainly showed me that properly compressed 128kbit audio can sound pretty good compared to how the old Fraunhofer IIS encoder used to do things back in the day, where every cymbal hit sounded like absolute garbage. And if that 128kbit audio is in a code like AAC encoded from source? I'm happy with that.

I don't think he's crazy. The loudness war means a lot of poo poo released on CD is overdriven and has the dynamic range compressed all to poo poo. If you tried doing that with vinyl (to that extent, vinyl's where the trend started in the first place), you'd snap off styluses.

Grimey Drawer

Correct me if I'm wrong but isn't the lack of dynamic range (compression) and overall loudness similar but different? Compression generally means to me that the softest guitar plucking would be the same volume as the drums in the mix, resulting in a really boring and flat sound. This doesn't necessarily mean the waveform is clipped or that the needle would jump out of the groove if it was pressed to vinyl. Loudness is where you see clipping and it's like they just cranked the master volume slider to 11, and this is the real cause of listener fatigue. So with that in mind, modern vinyl albums might have the same level of compression as their CD versions (because they were likely made using the same digital master), but the overall volume is lower to prevent clipping.

Yep, all these points. I jumped into MP3 back in 1997 and over time with portable devices that supported it (like MP3 CD players, iPods) it just became my absolute go to format while CDs took up space and didn't look as pretty as vinyl (which I started collecting around the same time). In the end I put most of my CD collection into binders with just the front art and the disc, half of which are probably in the wrong slot or on various spindles somewhere.

Quality wise, I have zero complaints about CD at all. It sounds great, and tbh as good as music probably needs to sound for the mass market. Digital gives comparable quality and an absolute ton of convenience positives.

So with that in mind, modern vinyl albums might have the same level of compression as their CD versions (because they were likely made using the same digital master), but the overall volume is lower to prevent clipping.

You're right, and also wrong. Loudness and dynamic compression are indeed two different things, but they've both been used for a while to make hotter records. Photek and some other DNB producers owned their own presses, and would reportedly push the amplitude limit to the point where the cutting needle would break, and back off a little from there, just to ensure that when their vinyl got played at a club it'd be *that* much louder. Partly that's because in club scenarios you have problems with gain before feedback, because with poor isolation of the turntable and really loud speakers the bass from the speakers starts getting picked up by the phonograph cartridge, so maybe you legitimately want a record that's got a higher amplitude to begin with. But CDs can be abused to much greater levels

Perceptually/psychoacoustically, dynamic compression will make things sound louder, even though the peak amplitude might be no higher. That's why (until the CALM act changed things), commercials on TV would sound so much louder than the programming they were accompanying: the commercials were dynamically compressed to a higher average range, so even though they wouldn't show up any louder on an SPL meter, they *sounded* louder because they were all peak. And you definitely get this in CDs; even for reissues of stuff from the 50s or 60s, they just get slammed all the way to the wall and anything that relied on dynamics for effect is just ruined.

RS had a good article on this years ago, and I don't think things have gotten much better since then:

You don't have to dance around it by saying dynamic compression makes things 'sound louder, psychoacoustically'. It makes things louder period (post make up gain). Just not the peaks. Everything else literally gets made louder. More/longer parts of the track will be loud. It won't register a higher maximum on a peak meter, but a peak meter isn't a measure of anything but whether you are going beyond the technical limits of your gear. Pretty much any other measurement of loudness will give you a higher readout.
