    Posted: March 13 2006 at 05:38

Just to clarify my own position on hifi systems:

  • I believe that an audiophile system ($2000 up to $20,000 and above) may very well sound much better than my own really cheap ($500) system. But I don't think that the difference would increase my enjoyment of the music. And I am convinced that 99% of the improvement results from the amp and speakers. The other components have little to no effect on the sound.
  • I don't think that any custom power line cables can improve the sound of a hifi system. In rare circumstances with extremely unstable power feeds additional hardware may be required to stabilize the voltage, but very rarely (like 0.1% of all situations).
  • I think that any speaker cable that costs more than $20/meter is a waste of money. It is explained in great detail on various websites. Even some hardcore audiophiles admit that.
  • I believe that some tube amps sound better than transistor amps. However, they change the signal. They add distortion, but a "good" type of distortion which creates additional "warmth". Some may prefer an absolutely linear amplification though ... so while I like the sound of tube amps, I would say that transistor amps are more accurate.
  • CD vs. Vinyl ... that's a difficult question. Let's put it this way: Some vinyls sound better than some CDs. Some CDs sound better than some vinyls. But I don't think that there is a general rule.
  • "CDs sound harsh compared to vinyls": I think that's nonsense. Many audiophiles are consistently ignoring the fact that CDs have a greater frequency bandwidth than vinyl and tape. CDs go up to 20khz, while vinyl and tape only reach 17khz at best. However, the original master tapes typically reach beyond 17khz, so a remaster directly to CD might reveal more details in the upper frequency range and therefore sound more "harsh". But in this case the harshness was already there on the master tape, and is hardly a problem of the CD.
  • "The 16 bits of the CD are not enough to capture the full dynamics of an analog recording": Nonsense. Let me just clarify that 16 bits does not equal 16 steps. 16 bits equal 65,536 steps. The resulting dynamic range is much greater than that of a vinyl recording. In fact it is so much greater that on some CDs the sound engineers are already compressing the signal because otherwise some listeners complain that there is too great a difference between silent and loud parts. Of course this compression is bad, because it changes the signal ... such a compression should be applied as a filter during playback, not during recording.
  • "Compressed audio (mp3 etc) doesn't sound as good as the original": That is true. However: Depending on the system that is used for playback and the situation (home, car, walkman etc.) it can be totally acceptable. Personally I easily hear the difference between 64kbps/128kbps files even on cheap systems, while 192kbps files are harder to recognize and (at least for me) acceptable even on a decent system.
  • "It is not possible to enjoy music on a PC". This is not true. It all depends on the components of the PC, and how it is connected to the amp. You have to use digital extraction of the audio, you must not compress the extracted audio, and the extracted audio must be routed to the amp digitally, without processing. If all these conditions are met, listening to audio on the PC is virtually identical to listening to audio using a CD player.
  • "Musical CD players are better than cheap CD players". Yes and no. "Musical" CD players do some advanced processing and are thus changing the signal. The result may sound better ... but not because the "musical" player does a better job at extracting the audio from the CD. It cannot extract other (or more) information than any cheap player.

  • First of all when you first get used to a $20 000 system it would be PAINFUL (atleast in my experience) to get back to using a $2000 system and certainly i think that when i can really feel the presence of the entire symphony orchestra in the room will make me enjoy the music even more. Especially on recordings with grand orchestras the weakness of low end systems will shine through.
  • I use proper neutral cables with bi-wiring that does not add anything to the sound...it cost about $200 pr meter and its really worth it! First of all the gold used in this cable has to cost a bit and there is a special soldiering technique which guaruantee no loss. By using Bi-wiring you shorten down the signalway from the crossover filter and by that reduce loss. Also it is 100% pure copper not remelted copper that will also cause signal loss. Also the isolation against other Electrical Signals is of higher quality than low end cables. All in all these things surely make a difference!
  • I dont really like Tube amps but i would only say that Pure Class A amps would come close to the warm sound that certain Tube Amps can give
  • Vinyl will always be better than CD
  • Compressed Audio is always horrible on quality headphones!
  • Well certainly you can enjoy music on your PC but you can't make it sound as good as a proper dedicated system!
  • Ofcourse they are better! More expansive D/A converters provides a better resolution and adds more detail to the sound. Also some CD players have sampling modules which can give some better dynamics!

You should try to know.
Indeed, if you don’t really like music, probably “the difference would not increase my enjoyment of the music”.

“The other components have little to no effect on the sound”

>>>

So no difference from one source to another. Ridiculous statement.

“I don't think that any custom power line cables can improve the sound of a hifi system.”

>>>

Reality is something else.

“believe that some tube amps sound better than transistor amps. However, they change the signal. They add distortion, but a "good" type of distortion which creates additional "warmth". Some may prefer an absolutely linear amplification though ... so while I like the sound of tube amps, I would say that transistor amps are more accurate. »

>>>

I’ve already explained you that reality is very different.
A solid state amp is UNABLE –except some like the Cello reference II, but it’s VERY expensive- to reproduce
Highs without AUDIBLE distorsion (the difference between theory and practise one more time).
The obvious example are difficult instruments like : violin, trumpet!!!
Try to reproduce a trumpet on a transistor, it’s horrible. (it’s the same numeric vs analog)
Tube amps are FAR MORE ACCURATE AND TRANSPARENT IN THE HIGHS.
You will hear far more details. Same than for numeric vs analog.



"CDs sound harsh compared to vinyls": I think that's nonsense

>>>

That’s not a nonsense, but a report. Listening tests, you know?

The problem is that numerization AFFECTS the original signal by simplifying it, so info missing.
With analog, the signal is intact, there’s only additional noise and/or crack and pops.

MOREOVER, what you don’t know cause you have never heard, is that a big CD player on a good system reveals that most Cds have noise, even DDD ones!!!

The bandwidth is obviously not the good criteria.
Ther’s even some supersonic noise (up tuo 20khz on the CD) and it affects the signal and adds a lot of harshness. That’s WHY my Pionner burner uses a converter which:

-Recalculates missing infos, which results in a softer sound
-Cut freq up to 20khz to avoid supersonic noise!


An upgraded Nakamichi 700 ZXL tapedeck (so pure analog) has been measured going until 23 KHZ…

"The 16 bits of the CD are not enough to capture the full dynamics of an analog recording": Nonsense. Let me just clarify that 16 bits does not equal 16 steps. 16 bits equal 65,536 steps. The resulting dynamic range is much greater than that of a vinyl recording.

>>>

Completely false. 16 bits is not enough, that’s why they now turned towards 24 bits.


“The resulting dynamic range is much greater than that of a vinyl recording. In fact it is so much greater that on some CDs the sound engineers are already compressing the signal”

>>>

That’s not the reason why they compress the dynamic.
And we agree that it’s very bad:

“What happened to dynamic range? That's a question that should be asked of record labels, producers, artists, and last but not least, recording and mastering engineers. The question needs to be asked because we're the ones responsible for what's happened to our music. The music we listen to today is nothing more than noise with a beat. It's not because it isn't good music. It's because it lacks dynamic range. When music lacks dynamic range, it lacks punch, emotion, and clarity. The record industry insists on blaming Napster, MP3s, CD burners, and a host of others for the lack of CD sales. While there is some truth to their constant whining, they only have themselves to blame for the thievery that's going on among consumers. I'm not an advocate of that thievery. No one has the right to steal someone else's property. However, the music industry needs to reevaluate what it considers to be good music. The music available to the consumer today isn't musical at all. It's best described as anti-music. It's anti-music because the life is being squashed out of it through over compression during the tracking, mixing, and mastering stages. It's simply, non musical. It's no wonder that consumers don't want to pay for the music that's being produced today. It's over priced and sounds bad. Our musical heritage is being threatened by this anti-music. It's time for all of us in the music industry to wake up!

What is dynamic range anyway? Dynamic range is the difference between the softest and loudest sounds we can hear. Or, to put it another way, the difference between the softest and loudest sounds in a recording. Dynamic range is measured in decibels (dB). The typical dynamic range for a cassette recording is around 60 dB, while today's digital recordings (CDs) can reach a dynamic range of 96dB. Compare this to 120dB or more for live performances.

For years we've tried to recreate the excitement of a live performance by trying to maintain as wide a dynamic range as possible. This has always been difficult with analog recording. We had to keep the softest signals above the noise floor while keeping the loudest signals below the level of distortion. To keep the soft signals from being buried in tape hiss, we had to record with as high a level as possible. To keep our loud signals from distorting, we had to compress the signal which resulted in a restricted dynamic range. As the years went by, many improvements were made in recorder and tape technology. This, along with various types of tape noise reduction systems, helped to improve the dynamic range of our recordings, but it was still limiting.

Then, one day we awoke to a new technology. It was called "digital recording." Wow, now with a dynamic range of over 90 dB, our recordings could almost rival a live performance. Well, in theory. However, the music industry had other ideas.

Rather than use this new technology to take advantage of it's wide dynamic range, the music industry went in the opposite direction. They decided that louder is better. Suddenly, we found ourselves in a race to see whose CD was the loudest. The only way to make CDs louder was to keep compressing the signal more and more. That's where we are today. Everyone's trying to make their CD sound louder than everyone else's. The term that is used for this process is called, hot. Yes, most of today's music is recorded hot. The net result, noise with a beat.

In December, 2001, several prominent individuals in the recording industry served on a panel to judge the best engineered CD for the Grammy's. After listening to over 200 CDs, they couldn't find a single CD worthy of a Grammy based on the criteria they were given. Everything they listened to was squashed to death with heavy amounts compression. What they wound up doing was selecting the CD that had the least amount of engineering. In reality, the winner didn't win because of great engineering, he won simply because he had messed with the signal the least. On second thought, maybe that was great engineering. Anyway, what a way to win a Grammy.

Here's a quote from Roger Nichols, one of the participants on that panel. "Last month, I listened to all the CDs submitted
to NARAS for consideration in the 'Best Engineered Non-Classical' Grammy category. We listened to about 3 to 4 cuts
from the 267 albums that were submitted. Every single CD was squashed to death with no dynamic range. The Finalizers
and plug-ins were cranked to 'eleven' so that their CD would be the loudest. Not one attempted to take advantage of the
dynamic range or cleanliness of digital recording." - Roger Nichols Grammy winning engineer for Steely Dan, Beach Boys and
more. EQ Magazine January, 2002, issue. »

Another thing which show that digital doesn’t works at all.

“Compressed audio (mp3 etc) doesn't sound as good as the original": That is true. However: Depending on the system that is used for playback and the situation (home, car, walkman etc.) it can be totally acceptable”

>>>

We already agree that on a computer or an ordinary system, no audible difference.


"Musical CD players are better than cheap CD players". Yes and no. "Musical" CD players do some advanced processing and are thus changing the signal. The result may sound better ... but not because the "musical" player does a better job at extracting the audio from the CD. It cannot extract other (or more) information than any cheap player.”

>>>

Musical does not mean expensive. There are cheap CD players which are musical (I.E Nad, Rotel, Rega, Naim, Creek… ) , very expensive ones which are not at all. Price means nothing. But of course a top musical expensive player will beats a cheap musical. It’s the hierarchy.
“and are thus changing the signal”
It’s the contrary, there are more neutral and respectful of the original signal.
I’ve listen to big CD this week end: Drive Teac VRDS 20 with Brinkmann Zenith III converter.
The differences are incredible from one to another, as it’s very neutral and revealing: A bad record will sound very harsh, a good recorded one will be incredible. Unfortunately, very few are good in rock. It tells the truth. But when it’s good, it’s good.

Also by using spectrum analysis you can see that a tone of 15 000hz Sampled on a CD 16bit/44,1khz will be distorted.

Analog devices can reach much higher frequencys before becoming distorted so this means albeit the CD player can sample sounds as high as 22 000hz which is higher than the human hearing (20-20 000hz) it will begin to distort alot sooner.

True!!!!
Moreover, i prefer a tapedeck or a tuner limited at 16 khz, but which does well what it does, than a CD player going at 20 Khz, which distors far more as says Lindsay.

Well seen!

16 bits Cd performance does even not meet the technical spec required by the "Red book", when it was originally defined.

Numeric is a disaster.

At my job, they replaced the old classic phones by new "voice-on-IP" phones:

When i call someone and that there's a waiting music, sound is more distorded than in 1900 with wax records...
What a progress!
Same if you compare fix phones's quality and mobile phone sound quality.

Sorry ... but that's absolute nonsense. No D/A converter in the whole wide world can "add detail". There is also no way to "give better dynamics". All these "musical" circuits do is to apply post processing to make the signal sound more pleasant. If it sounds better to you - no problem with me. But it has nothing to do with improving the quality of the signal.

If you hear an instrument on a CD player that you wasn't hearing before with another one, do you allow us to say that ther's more detail?

It goes further on every criterias, that's all!

Let me rephrashe it: it does not add any detail to the signal, it just make the signal's reproduction more detailed

A Upsampling board would boost the normal cd dynamics from 96 db/s to perhaps a 100 by sampling the it up to 192khz

You and your spectrum analysis ... seeing distortions on a spectrum analyser and actually hearing a difference are two completely different things.

You make no sense here ... dynamics don't have anything to do with frequency. The dynamic expansion is due to the fact that these circuits convert 16bit to 24bit. This is done by interpolation, which by nature smoothens the signal. But this technically is a degradation of the signal ... it may sound better to you, but actually information from the original signal is lost.

Aha i think anyone will know that the tone is distorted because at 15 000khz there will be only enough space for three samples per cycle.

And three samples per cycle the Digital media will not be able to reproduce a Sine wave...infact the wave it reproduces will be more of a sawtooth or square wave....and that is certainly a horrible distortion!

Yes it goes from 16/44,1khz and by using interpoltion and complex filtering on the signal it is then sampled up to 24/192khz it would improve dynamics a tiny bit and i certainly does not hear any negative effects by using this technique.

And numeric distorsion is horrible compared to analog's distorsion.
Actually, when you record on analog, you can add a little too much signal and distors a little, but not in digital.

And if you take a sine wave and then convert it to a square or saw toothed wave it will sound reall really distorted...i think most people would be able to hear that.

Of course you can't hear them because they happen beyond the resolution of the human ear. The step towards 192khz was mainly done because professional audio equipment works on that level. The problem is that when mixing different sources together and applying digital effects signal artefacts are created which can be in much lower frequencies than the source signal. Because of that professional equipment uses frequency ranges up to 4 times the CD range.
