Total harmonic distortion or THD is probably the more regular little T.L.A.s (or Three letter acronyms) you are likely to see in many manufacturers specs. But exactly what is THD, is it all that important and what degree of THD is acceptable for HiFi and AV equipment?
In audio reproduction between the input stage and output stage of E&T audio rack you will see some noise and distortion introduced to a signal. A few of this distortion is produced by the circuits and physical elements introducing signal harmonics at double and triple the frequencies from the original signal. These added signals are technically called Harmonic Distortion. THD is really a measure of the differential between the input stages of the system and the audible extra signal at every harmonic. The THD calculation doesn’t consider the relative level of each harmonic. EG: One amplifiers output on the 2nd harmonic could be more than the output at the 3rd. Another could create equal levels at the 3rd and 5th. The 2 amps would sound totally different yet could have the same measured overall THD.
In most hifi circuits including amplifiers and pre amps one should expect a price of less than 1% THD because it is relatively easy to get rid of a substantial amount of THD from amplifier circuits using various techniques. Unfortunately it really is far harder to stop significant levels of THD from being made by the physical aspects of a setup such as the Topping NX4 DSD. Higher amounts of THD are common in cheaper end speakers especially at higher volumes. Speakers with higher levels THD tend to cause “smearing” of audio, and result in poor imaging along with a “muddy” sound. In reality you ought to test a component ideally inside the room it is going to be found in and at a volume level chances are it will commonly be heard at to find out if the product is suitable for purpose.
Your house cinema system or audio visual system will need a particular amount of cabling to maximise possible sound quality of your system. Therefore you will need to improve your equipment with digital connections to every audio visual component to achieve the best listening experience. The very great news is that you could obtain noticeable quality of sound improvements from your own home cinema system through using suitable digital HDMI interconnects (High Definition Multimedia Interface).
In this article we explode the business biased HDMI Cable Reviews and explain to you how with inexpensive standard HDMI cable you can achieve excellent results and boost your home cinema listening experience and acquire noticeable sound quality improvement using your audio visual system utilising possible digital connections.
Picking the best HDMI cables for your own personel system is a pretty straightforward process and there are some things that need considering before you purchase. Firstly, tend not to get brainwashed by retail shops that try to sell you the eeogzu expensive cables since they would like you to invest as much as possible rather than understanding the needs or requirements of your house cinema setup – don’t be fooled.
So what HDMI Cable might be best suited for my home cinema system?
Firstly, the basic principle behind HDMI is to transmit uncompressed digital data via 2 interfaces and digital data cables ought to be mainly compared by the quality of the components and manufacture. The Shanling TEMPO available seem to focus on the more you spend the more you accomplish – well stop and you better think again. Good quality creation of an inexpensive HDMI connector cable affords the same results as spending 10x or 20x more.
