Yeah, I still like to listen to CDs at home, I have a large collection. I have a couple of MP3 players, iPod and Creative, that I like to use when on the go. I do have a CD player in my car, but usually plug the MP3 players into the jack on the stereo. I have around 10,000 songs on each MP3 player, and no way I am going to carry that many CDs around. :o

I know what you mean about the CDs, just look at how the selection at Best Buy shrank from a huge selection to practically nothing. But, I don't think that CDs will disappear, too many people still use them and have huge collections, so there will probably be a good used market for a long time. If people still use vinyl and 8 tracks, I think CDs will stick around even longer.

I bet that some of the older members here still have some wax tubes and aluminum tubes, and think that they are the best. :lol:

Yea, but I do love a nice tube amplifier and good turntable to spin vinyl :mrgreen:

I use a SS and a modeller for playing. I haven't found a tube amp I like yet.

For playback, a DAC into my PC and a SS amplifier for my good phones. I see no reason why you'd want a tube amp for playback of music, 'cept for the cool glow. The whole point of tubes is what they do when you push them too hard during the creation/playing process. They don't do that, and aren't designed to do that in hi fi audio.

I get some still prefer vinyl, but it isn't better, just another user preference.

Even thought i'm a lot into computing and software programming, I prefer staying analog in music.

Nothing better than a nice Fender/Marshall or Vox tube amp because the sound changes a lot according to the state of the tube, the type etc.. something you don't have in solid state amps or in softwares like Amplitube that I use when my brother sleeps.

I hate digital pedals because when you use pedals, you get variations of signal because of the power supply used and the digital pedals don't have these variations.

This good old boy seems to really like digital modeling for recording and performing.

i have a large vinyl collection (not really a collection as i listen to them so technically not a collection but a huge pile). I also have lots of CDs and 500 gig of music digitally. I like vinyl a lot but when ever someone "gets rid" of their CDs i grab them up. I have a feeling that when the people that grew up with CDs realize they are all gone there will be a "CD revolution" and i will basically be sitting on bars of gold.

But i do really love everything about vinyl records. My tired ears are not fine tuned enough to hear all these compression differences and stuff like that, i just like them more. But i like the flash drive in my car that holds about a zillion and one songs on it too.

There is too much good music to acquire, and never enough money.

When I spend $30 on music, therefore, I prefer to get three albums, not one, with the added benefit that I can carry around my music collection in my pocket and listen with my super high quality headphones when doing such things as running and walking the dog.

Wow ... only three albums for $30??? You are not downloading from the right place. That could get you around 20 albums elsewhere. Just saying ...

When it comes to listening to music I am not certain it is possible to stay in a pure analog domain.

For example, lets say you have a turn table and an old school pure analog amplifier (tube or solid state). The chances that the recording you're listening to was produced from a pure analog source is very slim, unless you're listening to some very old vinyl. Even if you're listening to an old song, if it is on new media there is a good chance that it's been re-mastered with modern DSP hardware/software. I would be surprised if most of the original masters from famous artist have not all been transferred to a digital archive.

Someone in a previous post mentioned something about speakers converting digital signals to analog. You were correct in that we can not here digital but this has nothing to do with speakers. A digital modeling or playback system will use a Digital to Analog Converter (DAC) and output an analog signal to a standard pre-amp, power amp, speakers signal chain.

Also, only a marketing type would come up with the term "digital speaker". Technically, there is absolutely no such thing as a digital speaker.

Someone also mentioned using extremely high sample rates like 96khz or 192khz. I would suggest doing some research on "Nyquist frequency". In a nutshell what it means is that your sample rate only needs to be double the frequency range of the source signal you wish to sample. That is why the Red Book specification for CD audio was set at 44.1khz. The highest frequency detectable by human hearing is generally accepted to be around 20khz. Therefore 44.1khz is more than adequate for any audio system designed for humans. However, SNR and/or dynamic range can be affected by the sample resolution (not to be confused with sample rate). CD audio uses a 16bit resolution which, theoretically, should yield a SNR of roughly 96db. That ain't bad at all. Blu-ray uses a 24bit resolution for the audio which converts to a SNR or 144db!

There's also complaints of digital audio sounding brittle or sterile. I don't doubt that for a second. Believe it or not your hearing has to adapt to the sharper transients of an increased SNR. And your hearing will adapt - give it 30 days.

None of this matters if your playback system is a piece of crap. Cheap CD players, especially in the early years of CD, were prone to aliasing and other weird digital artifacts coming through. Even a quality system is not likely to match the SNR of the source media. I not familiar with the dynamic range of high end systems but I don't think they approach 144db.

There is little doubt in my feeble brain that digital is superior to pure analog. I say "pure analog" because even a digital system has most of the analog components of a pure analog system. When we factor in the 'bang for the buck' component pure analog doesn't have a chance.

Yes I know what the Nyquist frequency is, thank you. Now I suggest you do some research on oversampling; c.f. Chapter 7 of The Physics of Sound, 3rd ed., by Berg & Stork, for a lengthy discussion of how it improves the audio of CDs.

Well, that's BS. Speakers don't play 0 and 1's. Gotta be analogued somewhere in the chain.

Agreed.

Even in that diagram… the “Sound” part of that is obviously analog so there goes that.

Unless of course you’re a cyborg with SPDIF, Optical or AES holes in your head then perhaps you could in theory go “Fully Digital”

the point is that the signal is digital right up to the speaker. The speaker takes digital input directly. Digital speaker.

Dnote is a technology designed to modulate digital audio signals and reproduce sound by direct input to speaker units or voice coils. Because no amplifier or quality-deteriorating D/A conversion are required, sound is reproduced with the same high quality of the original digital sound source.

Now if only someone could invent a car that runs on sunlight. Oh wait, they did that too.
