One of my favorite pieces of insanity is people going nuts for original model Playstations as audiophile CD players.

See the thing is that you need to not just develop some stupid tweako bullshit product but you need to market the crap out of it including bribes er I mean ad buys in well respected audio magazines and getting space at trade shows and stuff.

I saw this linked on AVS:

A $300 amp and a $200 DVD player connected with cable from 7-11 sitting on a wooden chair

vs.

$12000 pre/pro, fancy "CD transport", fancy cables sitting on isolation stands.

Results:
38 persons participated on this test
14 chose the "A" system as the best sounding one
10 chose the "B" system as the best sounding one
14 were not able to hear differences or didn't choose any as the best.

If I was building a listening room I'd probably spend more money on the furniture than the amps. You can get a killer pro amp like a Crown XTi for a grand.

Creative is about as far from audiophilia as you can get though, retarded claims about audio quality permeate the low end of the market too, e.g. Bose.

Speaking of which one of my favorite products is the Slim Devices Transporter. The normal squeezebox has a very good D/A converter and pretty high qality components. They couldn't get high end buyers to believe that it sounded good at $300 so they made a $2000 super squeezebox with the best of everything and a fancy metal case and it's actually sold pretty well.

The funny thing is about all this bullshit with CDs and whatnot is that if any of it was true, it would mean that data corruption on software-based CDs would be rampant. If you need to freeze/color/shave a CD in order to get the "true" sound, then how come if that same CD had data on it that data would be usable without special treatment?
I froze my MS Office install disc and now my bold fonts are "fatter", my Excel column dragging is smoother and my PowerPoints have a more holographic presence with more forward oranges and sparklier bullet points

I had a real winner on the line a few months ago on diyaudio.com, he claimed that the same CD ripped using EAC would result in different sounding wave files depending on if it was ripped with any old drive and a fancy blu ray burner.

This INCLUDED him showing md5 hashes of the two files clearly showing they were identical down to the last bit. He claimed the two .wav files clearly sounded different. Must have been the hard drive storing the jitter! :suicide: Except even then he claimed he could copy the files around (burn them to a data disc, etc...) and still hear it.
I'm pretty sure this guy ended up getting different MD5s because the filenames were different.

I don't know how anyone could miss the way cymbals sound at really low bitrates, especially using MP3. There's a few songs with very distinctive synth noises I can always tell when they're compressed, namely "Cowgirl" by Underworld and "Looking for the Perfect Beat" by Afrika Bambaataa. I think that's because the compression algorithms are tuned more towards vocals than perfect waveforms. The original MP3 creator used "Tom's Diner" extensively when working on it.

And the speaker in question, as part of a $300,000 system (the turntable accounts for half of that):


Why are there 5 amps? Or is that 4 amps and something else?

As far as "what exactly does all this fancy poo poo get you?" that's really more about the customer than the product. Some people want to own hand-built objects made out of exotic materials and are willing to pay more for it regardless of if it makes any real performance difference. A $150,000 Ulysse Nardin watch doesn't keep better time than a Timex but it sure looks cooler.

Yeah what I'm saying is that there's a market of people who will buy the fancy-looking thing with outrageous claims. It's not a big market though, these companies that make $30,000 amps probably only have a handful of customers so while they're clearing $10k/unit if you only sell 20 a year that's maybe enough for a 3 or 4 person operation depending on how much they spend on marketing.

If tomorrow some researcher came out with a $200 utterly perfect speaker driver there would still be people willing to pay $15,000 for "the best" speakers with those drivers in them.

What are the "dual mono power supplies" about? Is there actually a separate power supply for each channel? What's the point on a preamp and line stage? They barely use any power compared to an amp.

Power stuff is right behind cables on the worthless snake oil ranking IMO.

placing the power supply (and more specifically, the transformer) as far from possible from the audio path is a good thing to do
Before the advent of switched-mode power supplies sure but all these dudes running linear power supplies or even off of car batteries are clearly in the "tweako BS" category in my book, especially since linear power supplies are far more likely to hum and act strangely within normal AC power variations.

Actually for critical listening in a quiet environment using a really good needle there is some risk of picking up motor noise from a direct drive turntable. That said you can get a REALLY good belt drive turntable for home listening for a grand or so.

FLAC and ALAC are about 50% smaller, on average. That's significant.
More like 30-40% smaller, it depends on the music. I'm only doing it for the tagging really, it's not like a 200 gig library is that much more manageable than a 300 gig one. I think my ALAC stuff averages around 400 megs per album.

here's a gem from the squeezebox forums:

quote:

I said I do hear a difference between networked SBS or TinySC, at this point I don't know for sure why. It MAY be different data, but I don't think so. Phil's test will prove that one way or the other.

If the bits are identical then "proving" it gets hard. At this level of quality (I DID say the touch's outputs are very good didn't I?) finding iron clad causal relationships between measured signal parameters and perceived sound gets difficult, the differences in the signals are very small. By the time you get sensitive enough instruments to measure the small differences you have a lot of noise sources riding on top of things. It seems the human perception system can be affected by very small amounts of certain types of distortions even when they seem to be swamped by other distortions and noise. Unfortunately we don't know what these are so its hard to come up with filters in the measuring systems to match.

The point of all that was that if you want hard measurement data that proves it, you are probably not going to get it. That leaves what people hear. Thats much more difficult to "prove".

edit: oh even better

Bytec posted:

FLAC and PCM should sound the same because both are losless formats.
If only it were that simple!

There is no disputing that the 1's and 0's are correct. This, however, does not tell the whole story.

The differences being heard here will be due to increased jitter or noise - or possibly both - when the processor is working hard to decode a FLAC file.

The flaw in your reasoning is your assumption that the DAC sees 0.9V or 1.1V as "one". This is not the case. The DAC has no concept of bits. Voltages go in, voltages come out.
If digital signal transmission worked that way we wouldn't have hard drives or the internet. There is a wide range of voltages that the DAC will accept as "1", probably anything between 0.5v and enough to damage the equipment.

The Transporter is hilarious because you can tell they don't really "buy it" but when they figured out they could slap an extra screen and $200 more in "audiophile grade" components on top of a $300 squeezebox and sell it for $2k they figured why the hell not? There were people practically demanding it on their forums and they could get a jump on the rest of the audiophile market.
