Key Specifications to Consider When Buying a CD Player
Buying a CB player is not just about looking at the brand name. As much as some brands are associated with quality, it is imperative to look at the specs. CD player specs can be overwhelming. Seasoned audiophiles understand most details on the specification table such as abbreviations, symbols, numbers, and terms. To save you from the dash of confusion that often comes about when trying to decipher CD player terminologies, here are key specifications that will prove to be invaluable when buying a CD player.
Total Harmonic Distortion
The total harmonic distortion is an essential factor to consider when buying a CD player. This specification is often described using the symbol “THD+N” in specification manuals. Ideally, the total harmonic distortion is a measure of the amount of distortion added to the audio. Since distortions interfere with the quality of sound, the lower the value of THD+N, the better.
Signal to Noise Ratio
Also abbreviated as SNR, this ration describes the quality of signal sound compared to the levels of background noises. All CD players have some noise, only that the magnitude varies among different models. It is worth noting that the best brands have minimal noise, thus a lower signal to noise ratio. When shopping for a CD player, therefore, CD players with low signal to noise ratios are highly preferable.
Most CD players have a filter which removes sounds that are outside our normal hearing range. These filters are designed to make the sound clear and make hearing more enjoyable. Of course, no filter can be 100% efficient. The stop band rejection is a measure of the filtering efficiency. When it comes to CD players, a stop band rejection is measured in decibels (dB). A lower number is highly preferable. For instance,-100dB is better than -80dB.
Total Correlated Jitter
Jitters are playback gaps which are often caused by processing problems. These gaps are often too small to hear, but for anyone with a keen interest in musicality and detail, they do matter. When evaluating differed CD player brands based on their jitter numbers, again, a player with the lowest number is perceived to be better.
Many other features matter when buying CD players. Considering that digging into each detail in the specification list might, you should limit your options to the best cd portable players. But you also need to ensure you do your homework.
