BUT MY LIVELIHOOD DEPENDS ON THE FORUMS!
Speaking of which, there’s a dude on YouTube- Youthman— who built a HT out of La Scalas and like four giant subs stacked on top of each other and it looks like it slaps

IIRC he made a false wall and put 3 La Scalas and two columns of two subs apiece behind an acoustically transparent ~140” screen

I’m not making fun of him, mind you, this is the 100% right kind of audiophile idiocy, the exception that proves the rule

Also I’m p sure it topped out at 5.4 (5.2?)

I think it was 3 LSs and 2 Heresys in the back. And then I think the Heresys were also eventually swapped out for two more La Scalas. La Scalae?

It’s this, really. I could have the most tuned and balanced system ever built, but my apartment living room is going to make it sound like poo poo. I have a hand me down Sony receiver and a Bose Acoustimass setup, with the back speakers running off some cheap wireless poo poo that Best Buy said would probably mostly work, and it’s aggressively fine. It’s not like I’m going to have a loving meltdown if my AEW stream in a web browser doesn’t feel like I’m sitting in Florida with other people because it’s not mixed for 5 plus speakers.

just like you don't actually need lossless music, you don't actually need lossless surround sound. just gimme a 5.1 ac3 stream til im dead in the ground

Taking something that was compressed with a lossy codec and then compressing it again with another lossy codec can lead to weird quantization errors. Not that it will necessarily be audible, but it could be in edge cases.

La Scalas predate good measurement so they have a pronounced "house sound" that some people like.

Even 2 small bookshelf speakers and a sub are in my opinion enough for most people, provided you have some flexibility in positioning. It's the center channel that turns setting up a sound system into a fiasco. It was originally designed to be positioned behind the screen so everyone but the few people who don't use projectors are already starting at a disadvantage. Then you have a poorly placed speaker that almost all of the audio goes through.

There's a lot of :actually: with S/PDIF because it's a lovely, old format and doesn't have enough bandwidth to do more than 2 channels of uncompressed audio and doesn't support lossless compression for 5.1/7.1.

Basically, if you're sending two channel (stereo) audio, it's identical to using RCA. For surround sound, it doesn't support any of the modern formats and is generally not ideal but will still work "fine" for most people. HDMI is just way better in every way though so use that.

I'm using my Raspberry Pi to get streaming audio functionality on my old receiver, but the built-in DAC is awful and staticky so I started looking at replacements. I ordered this thing to get a digital out port using the I2S interface, and while researching options I found pages like this about stuff like the processor clock frequency. It sounds like audiophile nonsense to me, but I just got my first real sound system recently and don't know what I'm talking about so maybe I'm off the mark.

The RPi 4 rev b is the first one with a usb out that doesn't suck for audio so a hat is actually the right solution. That hat looks a lot like the hifiberry version. Once you have a decent digital out you're golden. All the reclocking and other bullshit in the world can't make digital audio sound any better. There's this guy on AVS who's constantly pimping reclocked Sonos gear [only $550 additional cost!] and when I called him on the fact that improving the jitter noise floor from -97dB to -105 literally can't make 16/44 sound better because the format only has a -93dB noise floor in the first place he got pretty mad.

I clicked the latter link expecting to find audiophile woo, but it is not. The author identified a real, non-woo, and significant jitter problem in the I2S signals generated by a RPi.

Whether or not it matters depends on the equipment connected downstream. It's possible to design an I2S receiver with integrated reclocking to recover a much cleaner clock from that signal. It's also possible to design one which just accepts it as-is and propagates all the jitter to the DAC.

I'm not that familiar with the RPi world. What makes early Pis bad at USB audio? A decent USB-to-I2S with its own local clock source to run the I2S seems like a cheap and good way to shave this yak.

Reclocking isn't actually bullshit when the i2s signal is alternating between two different clocks which are not the desired clock (but hopefully, over the long term, average out to correct). You're not going to get a clean DAC clock out of that signal without some TLC.

Said TLC certainly doesn't need to cost $550, of course.

I'm not 100% on what made the older RPis so bad at USB audio, something about a flaky controller on a shared bus? I didn't really start evaluating it until Sonos pissed me off earlier this year and I started looking at Roon. The TLC costs $25 like that daughterboard he linked but on newer ones USB DACs apparently work just fine. I'll probably end up doing something in a nice case with a DAC built in so it's a single box solution.

Probably from an objective “sound quality perspective”, but aside from the aforementioned Klipsch house sound, the really big Klipsch horn speakers are just really good at moving stupid volumes of air. Like even if they don’t get particularly deep they’re enormous, you’ve got like a 15” horn loaded woofer in a 4’ tall cabinet that can displace this relatively massive amount of air. And that’s before we add those bigass horn tweeters that Klipsch is so known for, and just how loud they can get with tiny amounts of power.

I think that combination of sensitivity, size, and for lack of a better term “brashness” really works in a home cinema setting, when the goal is so often to be overwhelmed by and enveloped in sound.

It’s kind of like comparing the experience of a well-tuned subwoofer that can get really deep to the point where you feel it and a fancy, super tarted up concert speaker that simply blows your head off with scale. It may not shine in certain aspects of home theater performance, like say—getting the most dynamic range or replicating a score with the highest degree of fidelity—but in other ways it’s very good at replicating the theatre experience by virtue of simply being so *big*. It reminds me of my HPM-900s and arguments about “East Coast” vs “West Coast” speaker voicing.

But also yeah—JBL is probably the one other major audio company aside from Yamaha that I straight up fanboy over, because they’re just so good at what they do, pretty much everything they make is at least ‘good’ or ‘as good as it can be in this segment’, and they’re completely no-nonsense about using their massive corporate scale and resources to make *actually* audiophile gear that’s *actually* well engineered and manufactured, and affordable + accessible to normal consumers instead of only chasing the bottom or going into luxury brand audiophoolery.

And the value for money that you get with their theater and JBL Synthesis stuff is probably unmatched if you really break it down. Also orange+blue is the best color combination even if it’s shared with the worst, most cursed NBA team

I think it's just a Chinese copy of that same hat, but the Hifiberry version isn't available anywhere in Canada so I went with the clone route for my 3B+. The equipment I got is probably not great but it's better than the speakers in the TV I found and repaired, and I paid $50 total for everything from someone local (a Panasonic SA-XR70 receiver, Yamaha NS-AP1500 speaker set and YST-SW010 sub for an apartment). It's a proper (if basic) receiver with HDMI so whenever I feel the need to upgrade to better speakers I should hopefully be able to do that with minimal issues.

I'm a complete home audio neophyte and I'm having fun hooking stuff up to it and learning how it all works, but as I do research I'm having some trouble discerning things that will cause actual problems from the BS, outside of the obviously insane stuff like cable risers and magic rocks. The new home theater system has me building better antennas for OTA radio and TV for fun and the information around that seems way, way more grounded than the audio stuff. It's mainly why I've started reading this subforum and thread lately, since people here seem less likely to believe that kind of audiophile nonsense.

The USB bus is shared with other stuff like the ethernet, and the whole thing is electrically noisy from what I understand. The SPDIF hat seems to have its own 27MHz clock but I have no idea if that would fix the issue, if there's even going to be a noticeable difference in the first place. I guess I'll wait for it to come in and judge for myself, it can't be any worse than how it sounds now. I hear people alternating between being dismissive of digital jitter and it being a real problem so I honestly don't know what to think, but that's probably something more suited to the home audio questions thread.

A friend posted up some photos of his beautiful game music vinyl purchases, the vinyl is that cool patterned type that just looks pretty on the platter of his cheap deck through his cheap speakers that he enjoys the experience of listening to.

His friend in the comments is yabbering about patterned vinyl and picture discs being worse than regular vinyl. I'm there like dude if you cared about audio quality first and foremost you wouldn't be listening to vinyl in the first place. Vinyl is about accepting worse quality for the experience of it being more interactive and involving and that's cool, you do you. Just dont try to argue it is the best medium for music.

Hoo boy this company sells some poo poo, like £200+ contact cleaner anyone?

quote:

Four years in development (and 500 prototypes later!) Chord Company is proud to announce its long-awaited ChordOhmic Transmission Fluid, a highly advanced liquid polymer solution, specifically designed to maximise the surface area of a variety of plug connections, improving their performance.

Developed by an acclaimed industrial chemist and Andante Largo in Japan, the new ChordOhmic Transmission Fluid works by deploying polymers to fill pits and imperfections on the surfaces of connections, creating a greater contact area and, therefore, improving the performance of the connection: the lower the resistance, the higher the current (signal).
Surely increasing the surface area of a contact would result in cables not fitting well and getting worn down even faster leading to a need to buy more cables?

For ultimate surface contact I just drop my gear in a bath tub filled with RO water. The reverse osmosis helps eliminate jitter. The tub is of course ceramic coated to block any electrical interference.

It's the only way to ensure maximum connection to all surface areas. Sure, the method may be considered wasteful, but the sound stage really opens up in that instant before the whole power grid goes down.

Someone reviewed it.

quote:

“My system sounds noticeably clearer and the music a tad more real after treatment. The midband is slightly more forward and the top end crisper and more refined. Playing a CBS LP of Simon and Garfunkel’s The Boxer shows a far better control of sibilance with this bright recording, and the positioning of the vocals is better focussed within the soundstage. Only a small amount of fluid is required, so 10ml should last for many years.”
