And then you will never have to leave your house

Hey, I'm already addicted to music. And I will even have to leave my house more often - to work and earn the additional money I need for my expensive hobby.

Agreed. I like how my system sounds, and no comment here can make me throw it away and buy a new one. But I'm always interested in improving the system.

Although I'm largely opposed to audiophile systems, I really try to understand them. Here's a summary of what I found out so far:

  • Upsampling really improves the sound, if done properly. I now know how it works and what it does, and technically it makes sense (it is not esoteric).
  • The single most important factor for the sound is the amp. Of course for perfect sound every link in the chain has to be good, I know that. But if you have a fairly good - but not HiFi/audiophile - system, upgrading the amp is what will have the most noticeable effect on the sound. Next is the source (good CD player/vinyl), then the speakers, and then the cables.
  • People like Oliver are right in that until just recently, PC sound cards did not do upsampling properly. Cards like the X-Fi are beginning to do so, and their specifications really do compare to good audiophile CD players (jitter, symmetric outputs, etc.), especially if they are connected to the amp digitally.

If I look at my current system (Computer (Audigy 2) - Harman Kardon Amp - Elac speakers), I think that I might buy an X-Fi sound card for €110 and maybe upgrade my amp to a Musical Fidelity Avalon ...

Can you post a link to a thread where they describe that in detail? I found some threads there, but the posts were not very clever - upsampling is an established technology and known to improve the quality of CD audio, and the members ridiculed it - a bit like myself in the other thread. Actually my statements still stand, but the smoothening of the signal can indeed improve the sound very much.

So what I need now is some article which in detail explains WHAT X-Fi really does to the signal (and not just assumptions, I need FACTS).

I wasn't entirely clear in my post. I think mainly the hydrogenaudio way of thinking is that any modification to the signal is unwanted (and, ideally, we should be able to trust the original recording enough to avoid any post-processing. It's just a sad fact that a lot of masterings are horrible as well ) What I should have said is that Creative cards are said to upsample poorly, which is definitely a real issue. Since it's the only card I have I can't tell how true this is.
 
Fact (well, unless someone faked it I guess )
Waves LinMB is just a multi(5)band compressor/EQ, and the X-Fi Crystallizer seems to have almost the same effects on the sound signal!

You can buy external hard drives fairly cheaply. I got one off ebay, 200GB for £70. It's a little noisy though.

I'm not sure if that's actually a perfect digital copy... Creative soundcards are notorious for upsampling to 48kHz when faced with a 44.1 signal. I don't know for sure if that affects the digital out but I imagine it would do, and that can only have negative impact on the sound.

At last, Creative is introducing a new family of sound cards which use the same upsampling filters as the musical CD players. So I will get the best of both worlds:

Computer with X-Fi sound card playing audio files in lossless formats -> connected to a Class A amp with good speakers.

Since you are unable to explain what makes the musical CD player better than the computer, I did some research on upsampling:

http://www.aslgroup.com/dcs/upandover.htm

Now this begins to make some sense to me. The musical player is interpolating the 16bit/44.1khz data stream to 24bit/96khz or even 24bit/192khz and the D/A converter operates on the upsampled stream.

The article confirms one of my earlier assumptions: both such players and "crappy" computers extract the same data from the CD, there is nothing the musical player can extract which the computer misses.

The data stream is actually smoothened by the interpolation algorithm, making it sound less harsh and more harmonic than the original signal.

Interestingly, modern PC sound cards also upsample 16bit/44.1khz CD audio to 24bit/96khz ... the question is now how the quality of the upsampling differs. I'll do some more research.

Stay tuned!

"I believe that CD's combined with a good amp and speakers are sufficient ..."

I think so.

I think you would be happy with a musical player like a Nad, Rotel, Rega, Naim, Arcam or even Musical fidelity if you want.

A musical integrated amp like Nad or Rotel and a pair of cheap Loudspeakears like Mission.

Without forgetting good cables (QED).

I advice you to turn on these cheap musical english brands. English are the kings of cheap and musical products.
To conclude, you don't need to invest much, but you need to have only musical elements. That's all.

Sell what you have (very easy) and follow my advices. For a very small amount of money, you'll have musical pleasure for years.

No need to apologize - the post was easy to miss next to these magnificent images of unaffordable mysterious devices.

BTW: I'm listening to Porcupine Tree - In Absentia in WMA Lossless right now, and - wow! What a difference to ANY mp3 format.

Yes I tried it out earlier today on a Zappa track, before I read this, and the difference was noticable. Hardly worth the effort for me though as I have a pretty basic PC set up!

You're always messing up the [/QUOTE] - tags, oliver!

I think it's insane to say that music only makes sense when listened to on excedingly expensive equipment. I already agreed on the superiority of Class A / Tube / etc. amps in comparison to cheap transistor amps. By the way - My Musical Fidelity amp indeed gave up the ghost ... and after that I bought the HK, because I was short on money and  not much into music at the time (that was a short phase in my life).

Maybe I'll buy an used Musical Fidelity X - amp sometime ... but right now I have other priorities. I know the difference which a good amp can make. The vinyl/CD/SACD/DVD-Audio discussion is also futile - I WILL stick with CD's, I made that decision long ago when my vinyl collection was destroyed by a water pipe leakage. I believe that CD's combined with a good amp and speakers are sufficient ...

...you want scientific theory?

There's one which says that tubes amps are less good than transistor ones cause the distorsion rate is higher.

"Unfortunatly" (for this theory), it's the contrary when you listen.

Ther's another theory which talk about pair and unpair harmonics, and this one match with the results. So, that may be an explanation of tube's superiority.

Eventually, only result matter.

There are many reasons which explain that a computer can't be a good source.

You want to compare top notch cd like mine with a crappy computer?

A little musical cd player like this one already explodes any computer.
And my CD explodes this little player.
So, it's mathematic...

[QUOTE=MikeEnRegalia]

That's insane. It leads NOWHERE. I can enjoy music even on a crappy mobile radio ... I listen to music, not perfect sound.


I even agree that vinyl CAN sound superior to digital media.



Good.
It's not insane, cause figure that you loose half of the music.
It's the magic of hifi: you'll re discover records you have listen to hundreds of times: you will discover instruments you have never heard on pieces you believe toknow by heart, hidden details, it's better than the fisr time you heard the music! isn't it good?
