@Genpattonjames: Whattt? You’re telling my ten thousand Zeus Apollo amplifier which claims stunning frequencies up to 100k with vapour stereo separation and its maximum wallet capacity is…………audiophile mumbo jumbo! As with anything, manufacturers almost have to wax poetic when they’re selling cables for a grand, and an amplifier for ten thousand dollars. I wonder if the one percent purchase such things to show off more than they actually sit down and listen to it. Once again for your honest and truthful facts regarding audio.
@A_RosnerNZ: I was at a live jazz gig last week. A singer and a 4 piece band. It was glorious. Punchy, dynamic sound, completely uncompressed, and if I closed my eyes I could point to where each musician was, and tell how far apart they were from each other. Then, I came home to listen to some recorded jazz on my reasonably good hi-fi. It was a squashed melee of compressed disappointment by comparison. The live performance was streets ahead in terms of soundstage, spatial cues, dynamics, you name it. A sobering wake up call. Recorded music is just a facsimile of live music, a reproduction of that lovely Van Gogh painting with the VGA 256-colour palette, if you will.

@VintageGearMan: Once again another smoking great video post!
@VintageGearMan: Oh lordy, here in Western North Carolina I had to deal with no hifi or a shower for 8 days straight! We got hit bad here from Helene hurricane. I feel super bad for so many that lost their lives and homes. Wife and I were blessed on no home damages. Phone service just came back a few days ago. It was tough not being able to watch these vids or listen to my newest old stock Paraidgm Ver.2 speakers. Yes I am spoiled.

@garyb2042: Cross talk is a real thing but I have a class d amp with speakers built to eliminate cross talk - the Polk Audio L800 speakers that expand the sound stage way outside of the speakers. Right technologies working together for an impressive sound.
@EricB256: What about smearing in the bass range? Is it actually possible for people to tell? Given the fact that some classic stereo LPs reportedly do have the bass on them in mono as a production trick to keep the needle from jumping out of the groove (or maybe for a similar purpose?), listeners probably cannot tell in the bass range. Will a more smeared bass sound warmer and a less smeared bass sound colder? That sounds more like a question to a synaestheticist.
@goodtimejohnny8972: Speaking of smearing, who is a real human on this channel and who is an artificial human? I'm confused.😂
@1974UTuber: I can hear when a stereo image is wider and more full. And I can hear when different backing vocals have been panned to either side. I can even hear when a phase effect on guitar or vocals is in stereo and swaps sides. But I will be damned if I can hear the mystical, ethereal, magic and pixie dust that self proclaimed Audiophiles can register with their $7K pure unobtanium interconnect cables.
Maybe what they hear is the sound of their bank accounts emptying knowing that the next better cable will be out next month and they simply must have it.
@paulmcdonough9595: Oh yes, amplifiers that oscillate and oscillators that don’t 😂
@Roddy451: The resolution on this videographic recording was masterful. There was some isolated loss of resolution on the lower reach, but the midsection and upper ranges afforded me unparalleled detail, openness, depth, and focus. There was a lack of nuance and definition when conveying the usual suspects. This confirms an analytic performance with some sense of occasional warmth. Is this video the best in class? Not exactly, but it has the ability and confidence to remain close to its competitors and, in some instances, get very close to the more expensive categories of videos. Remember, the only one who needs to like this video is you. 😜😜

@memcdm: Some very modestly priced components often sound very good. The law of dimishing return sets in rather quickly. These compromised components under $5000 are not expensive enough to be taken seriously by some audiophiles. Still they manage to deliver very fine sound with great recordings and if you really like the music you can enjoy it even if the recording is flawed. Audiophiles who spend thousands get upset when they hear that some reasonably priced stuff sounds perfectly fine. One reviewer I listened to some time ago suggested you could only get the real soul of a digital recording with a DAC costing at least $3000 and up! Really? Not really! I am not impressed that a $36000 pair of speakers (or more!) Sound good. I am impressed by a pair of powered monitors that cost $300 that deliver amazingly good sound with micro details, dynamics, timing and bass extension. They play loud enough to hurt and the sound remains clear and clean. Ok , to be honest if I want to get bass down to 16hz without breaking up at loud levels I will need to spend another $799. Ok and I'll add a$1000 for nice stands. Now I am up to $2100. What will i do with the remaining $33,900? Wow! I can go to a lot of live performances with that much money and at the same time, support the dedicated artists creating real musical magic with their artistry. To be honest, I've spend a lot more than $2100 on my main setup. I love it but I also love the cica $2000 set up just as much. O no! I've become one of those idiot audiophiles easily swayed by the temptation to keep spending more and more money on audio components in the pursuit of the illusion of creating perfect sound.
@DAVID-io9nj: Amazing how they know what the recording is suppose to sound like. They must have been the audio mixing engineer for that recording.
@Harrison-kt5xr: If two amplifiers sound different, at least one of the amplifiers was poorly designed (exceptions would be tube amps which are great to plug my guitars into, but which are an audio nightmare). Guitarists take advantage of the inherent non-linearities which are not desirable in audio. If an amplifier has a sound, there is something wrong with it.

@williamwescott4213: On breadth of sound stage, I can add that going out on my balcony expands what sound stage I'm hearing to match the panorama my eyes pick up (always assuming the recording captures a decent sound stage). The brain is more important than the ears in some respects.

@johnnaighley9252: When Nigel guy talks about "a smearing in the midrange" he could also mean that a curtain that hangs in front of the speakers, so there's a lack of fine dynamics and he cannot hear all the micro-details. The loss of clarity and missing micro-details may also not only be caused by dispersion of the wave packet of sound, but there may also be a significant portion of harmonic wave K2 which veils these details. K2 is particularly produced by NFB-less tube triode amplifiers. So what ape Nigel may think about the moon when observing it? ... ;-)

I get mental cramps when I listen to Darko talk about soundstage when 100% of what he listens to is one form or another of Electro. If you're going to talk about player placement and soundstage, make sure your recording was made with an ORTF, Blumlein or coincident pair of cardiods, a Decca Tree or a Neumann KU100, straight to stereo, with nothing else than a limiter and maybe a low-cut filter.

@Cyril29a: Smearing is nonesense. The signals travel nearly at the speed of light... There is zero chance we could ever perceive anything like this
@Douglas_Blake_579 replies to @Cyril29a: Smearing can happen when a device (amplifier, etc) cannot react quickly enough to follow the incoming audio signal. I.e. a low "slew rate". The voltage increases, then decreases before the amplifier can reproduce it. But it would have to be a mostly "brain dead" amplifier for that to happen in midrange frequencies around 2khz.
@Cyril29a replies to @Cyril29a: @@Douglas_Blake_579 That isn't smearing as it is described here. The amplifier being unable to reproduce the frequency quickly would basically increase signal noise as the transistor would essentially skip some phase changes or mush together some frequencies as it lacks resolution. The speed of the peroration would not be impacted as the signal would continue to be pushed through at a constant rate. This isn't a digital signal, there is no buffer to store the delayed signal. So either the signal passes at the same speed as all the others or it is transitioned to heat but the signal keeps moving forward. Smearing implies a signal slowdown and that just can't happen in electrical circuits not counting for capacitance but that is a whole other matter.
@Douglas_Blake_579 replies to @Cyril29a: @@Cyril29a
It's not the speed of the electricity that's the issue. It is the response time of the circuitry that is the problem.
By way of analogy... you might have a 500 horsepower car, but what good is it in a race if there's a 2 second delay after you press the gas pedal? The car will still go really fast, but it's going to take a long time to get there.
Now, what do you think happens if you feed a signal at 10khz into a circuit that can't respond beyond 5khz? Because of the time delay, the circuit will fail to fully respond to the signal resulting in a loss of amplitude and omission of detail above the 5khz limit.
ALL electronic devices have limits in how rapidly they can respond to changes in input... Just look up the data sheets for some transistors and op-amps it's actually specified by the manufacturer.
It doesn't matter how fast the electricity is moving... it matters how quickly a given component can respond to changes.

We all know that people suffering from "audiophilia" talk an awful lot of shit 😂 Maybe swapping my fuses or power cords would make a miraculous improvement to my soundstage (LOL) but no doubt my systems just aren't resolving enough 😆 To be honest, I wouldn't even WANT a system to be so "resolving" that it would be affected by power cords!

@shpater: regarding sound stage:
1. Cross talk is the least issue. more effective is channels differences with phase and gain variations between frequency. this can be "Easily" Tested when playing back a mono recording, inverting one channel and play back the output in mono Mode. Any signal that you may hear which is different from a white noise would be channel difference plus distortion. both will reduce the sound stage image.
2. Room reflections as well as speaker placement within the room are much more destructive for soundstage than any reasonable and better amplifications/cables.
3. Time delays and etc.: This is tricky. if both channels are exactly match in built, the the sound maybe impacted, but not the sound stage. Symmetrical timing issues has other effects on the sound perception but not on sound stage itself.

@Douglas_Blake_579 replies to @abehollander881: There was a shift in system design about the time the stuidio engineers realized that a CD can output some very high levels... launching the loudness wars.
Before that your typical power amp had an input sensitivity for clipping of about 500mv (0.5 volt). The higher drive levels from CDs resulted in a shift to 1 volt and more recently they are drifting towards 2 volts.
If you are unsure, I'd advise you to have a technician check your gear to be sure it's not being overdriven.
Your best bet is to not run anything at full maximum gain. What I do with my setups is to max out the pre-amp (typically a software control in a DAC or PC) and then adjust the power amplifiers to the maximum listening level my clients are likely to ever use. From there the actual listening level is controlled from the pre-amp volume controls. (Typically this lands everything at about half volume for normal listening)

@peterwollenberg4905 replies to @fredashay: Pharmacologist here. You cannot do a double blind test and there is no reason to do it in audio testing. Double blind in a clinical setting means that neither the physician nor the patient knows whether a verum or a placebo is given. Only the supervisor knows. This is done to avoid the expectation of the physician influencing their clinical evaluation of effect. The doc would definitely question an improvent when they know that the pat received the placebo. This is neither needed nor possible when testing audio equipment. It is sufficient that the "golden ear" who evaluates their listening experience is blinded. I did such a test btw with an audiophile friend of mine who claimed his new 1500 $ power cable improves the sound of his equipment significantly. I changed this new power cable against his old "cheap" 50 $ cable 20 times at random (random sequence generated with a computer beforehand) behind his back.

@Douglas_Blake_579: After listening to hundreds of subjective reviews over the past 5 years, I've reached the conclusion that while "reviewing" a device, most of the audiophile touts are actually critiquing their source recordings. Almost every attribute they rattle on about originates in the source recording, not the doodad being reviewed.
This, of course, is why we use test tones and measuring equipment, rather than relying solely upon our hearing when assessing a piece of equipment.
One of the worst aspects of the "loudness wars" is that in compressing, limiting, autotuning and quantizing a good musician's work into a wall of excessive distortion, modern recordings are now almost monophonic and seldom have enough channel separation to produce anything beyond a wide phantom centre image. Most recordings from the 70s and 80s do far better.
Also: David's trick of dummy loading one speaker while listening to the other with no input also reveals one of the biggest flaws in linear power supplies... Don't be surprised if what you hear from the mute channel (the one with a speaker connected) is a modulated 120hz hum as the power supply dips and recovers with the intensity of the music. Switching supplies being inherently regulated at very high speeds got rid of that quite nicely.
@thomaslutro5560 replies to @Douglas_Blake_579: What you said about critiquing recordings is 100% spot on. And it goes way back. Pages on pages in hifi magazines over decades in my case. I've only kept my subscription ti HiFi News, mostly for staying somewhat informed about news in broad terms, and only partially read them. All the other ones are gone. I very much enjoy Erin's audio corner though, not for purchasing advice but for the educational value in comparing listening impressions (he actually talks about what the speakers do) and the Klippel measurements. Much the same with this channel, a bit of help with understanding.

Damn ... this is frustrating. I just spent most of half an hour giving you a nice complete answer and it just got up and vanished.
Short answer ... Yes, most audio "reviews" are simply advertising and should not be seen as useful beyond that.
I've frequently grumbled about the lack of information; various inputs not tested, features not discussed, menus not explored, and so on. I get the distinct impression these guys are hooking the thing up, listening for a couple of minutes, then writing their scripts... with no serious intention to help any of us make better buying decisions.
If you are interested in diving further, there are a number of online basic electronics courses you can study and a real wealth of web-based information on various topics. Just be sure that whatever info you take in can be verified outside the audiophile community.
@thomaslutro5560: Paused to ask a question. I don't expect hearing any crosstalk from my electronics. Though the 25-35dB of a (good) phono cartridge, perhaps? I have some rereleases on CD which sound like they're a bit brutally panned and go to the speakers, where the original LP spreads the band across the full with. Might this be caused by failing to compensate for the far better channel separation in digital formats (in playback)?
@AudioMasterclass replies to @thomaslutro5560: I’m only speculating at present but the phasey rumble heard before the audio starts must persist through the whole disc. It wouldn’t be unreasonable to consider this might contribute to a perceived widening of the stereo image. [Edit: Corrected an autotypo]
@Douglas_Blake_579 replies to @thomaslutro5560: Short answer .... Yes.
@Douglas_Blake_579 replies to @thomaslutro5560: @@AudioMasterclass
This is why most competently designed amplifiers with phono pre-amps in them roll off below about 10hz. Some even have front panel switchable Rumble Filters built in.
It is indeed quite the surprise to pop off your grills and see the woofers moving in and out nice and slow like they are trying to swim to freedom.
@thomaslutro5560 replies to @thomaslutro5560: I didn't mean wide or narrow stage. Rather lack of gradual panning, so that you get sound localized to one speaker or the other with a CD. If there was crosstalk present at the -25 to 35 level, my intuition suggests the image slightly more diffuse and drawn slightly towards centre with the LP, in a way that might be subjectively better. So, compensating for the technical superiority of the CD would mean adding crosstalk to the master.
@Douglas_Blake_579 replies to @thomaslutro5560: @@thomaslutro5560
It could. But if you also have the pre-mix recordings you can re-pan it.

@Unavintage: I still have problems to detect transient. Even though read the meaning, I cannot detect it
@Douglas_Blake_579 replies to @Unavintage: A transient, acoustically, is a sudden loud sound ... like a gunshot or a slam hit on a drum. Electronically it is a sudden spike in output voltage, like you would get by briefly connecting and disconnecting a 1.5v battery across a power amplifier's inputs.
@jimallen1485 replies to @Unavintage: Please don't do that battery thing... the results could be very bad. 😮@@Douglas_Blake_579
@Douglas_Blake_579 replies to @Unavintage: @@jimallen1485
It can be done safely ... Just turn the amplifier gains down to about 1/4. Most modern power amps need 2 volts or more to reach clipping... you're only dumping in 1.5 for a part of a second. It will be LOUD but not typically harmful.
