why a home theature is not best for listening to quality music?

Question

I have been told that analog systems produce better quality music.

Answer 1

For a small percentage of people that may be true ... but ....



There is a debate over the relative merits of analog vs digital. That said, for many people -- certainly those with less than "golden ears" -- digital music (CDs, SACD, DVD-A, etc) offer excellent sound potential relative to analog (vinyl records).



I say 'potential' since the equipment and room make a HUGE difference to the sound. That said, recording quality varies widely too.



A 'home theatre' is not necessarily associated with poor sound. I have a home theatre setup (7.1 surround sound) with fairly high end equipment and have set it up for music and movies/TV. I like quality surround sound music (SACD, DVD-A, HDCDs) and find an HT receiver (in my case Pioneer Elite) works well for me. Some purists would sneer at my setup, but most people I know think the sound is excellent.



Part of the reason some people don't like digital music is because they claim it is harsh (relative to analog). In addition there are certainly some digital recordings where the dynamic range has been compressed badly. That said, there are many excellent digital recordings.



It's like everything, there is a huge overlap in quality between the two approaches, with analog maybe having an advantage for a few exceptional recordings and digital having some notably 'bad' ones. But analog is prone to developing hiss and clicks that digital is not ... and the big thing is the limited choice for recordings in analog.



Overall, if you have the ear and the money you may be a candidate for a dedicated analog setup for music and a separate one for movies/TV, but for the majority of consumers a digital home theatre setup capable of both music and movies is a much more cost effective approach.

Answer 2

Much of the debate is that the digital copy is not 100% of the analog image because it is just sampled 44100 times a second. Nyquist’s theorem dictates that a 20Hz-to-20KHz frequency response can be converted accurately to and from a digital source at 44.1KHz. This means that a CD that is mastered from an analog source should sound just like the source.



Two things then come into play.



The Source



If the source was of inferior quality then the CD will be of inferior quality. Many older CDs where mastered from tracks bound for cassette tapes and not cleaned up much. Subsequent remastering from original recording tracks with noise reduction and other processing offers improvement over the original analog source.



The DAC



How the DAC converts the digital data into an analog waveform is very important. Most higher end receivers employ very high quality DACs. Texas Instruments' Burr Brown DACs are highly regarded. Higher end receivers also add anti-aliasing processing to further enhance the DAC. Denon's AL24 processing or Onkyo's VLSC are examples of this.



So really a good quality receiver will sound just as good with a digital source as it would with an analog one.



Some of differences people perceive in analog audio could be attributed to psychoacoustics.

Answer 3

agb.. gave a great answer.



I would like to add a few thoughts because there are many issues here.



- "Analog is better" : There are lots of Luddites who want to return to the 70's era and claim nothing new sounds as good. I suspect you have been listening to some of these people. My advice: Dont argue, dont engage eye contact and walk away with a non-threatening pace.



- "Home theater is not good for music" : This is kind of true, but mainly because people buy less accurate speakers and amps for home theater and they 'watch' movies but 'listen' to music.



My advice:



If you love music - try to set up a separate music and HT systems. There are some very decent $800-$1,000 home theater packages you can put together that do a great job and will last years.



But your music system - put in a different room so you can:



- Indulge in proper speaker placements

- Invest in 2 really good audiophile grade speakers

- RTA for proper room acoustics

- Wall treatments

- Buy separate Pre/Amp systems so you can upgrade

- Play with all the 'myths' about exotic speaker wires, green marking pens, exotic wood disks under your electronics to 'sweeten' the sound, cable cookers, etc.

exceptionally plenty each speaker interior the marketplace can cope with the song an living house theater use. the known sound you like could come from call sort audio gadget and a receiver. There are very extreme end gadget for audio, despite the fact that that's going to likely be out of attain to your funds. Pioneer and Onkyo makes very sturdy receivers. Definitive technologies, capacity, JBL, Klipsch, Infinity and Polk Audio audio gadget are sturdy high quality audio gadget. i desire to advise you demo them at your interior sight retail save jointly with your individual source of song. wish this could assist you to out.
