Total harmonic distortion or THD is among the more regular little T.L.A.s (or Three letter acronyms) you are likely to see in most manufacturers specifications. But exactly what is THD, is it all that important and what level of THD is appropriate for HiFi and AV equipment?

In audio reproduction involving the input stage and output stage of hifi audio rack you will see some noise and distortion introduced to a signal. A number of this distortion is produced by the circuits and physical elements introducing signal harmonics at double and triple the frequencies of the original signal. These added signals are technically referred to as Harmonic Distortion. THD is a way of measuring the differential between the input stages from the system and also the audible extra signal at each harmonic. The THD calculation doesn’t take into account the relative amount of each harmonic. EG: One amplifiers output at the 2nd harmonic might be greater than the output at the 3rd. Another could create equal levels in the 3rd and 5th. The two amps would sound totally different yet could have the identical measured overall THD.

In many hifi circuits including amplifiers and pre amps you need to expect a worth of under 1% THD as it is relatively easy to remove a large amount of THD from amplifier circuits using various techniques. Unfortunately it is far harder to stop significant amounts of THD from being created by the physical elements of a setup like the Hifi Audio. Greater amounts of THD are normal in cheaper end speakers especially at higher volumes. Speakers with higher levels THD often cause “smearing” of audio, and bring about poor imaging and a “muddy” sound. The truth is one should test a component ideally within the room it is going to be utilized in and at a volume level chances are it will commonly be heard at to ascertain in the event the method is acceptable for purpose.

Your house cinema system or audio visual system will require a particular degree of cabling to maximise the available sound quality of your own system. Therefore you will need to maximise your equipment with digital connections to every audio visual component to obtain the best listening experience. The very good news is that you could obtain noticeable sound quality improvements from your own home cinema system through using suitable digital HDMI interconnects (High Definition Multimedia Interface).

In this post we explode the business biased HDMI Cable Reviews and demonstrate how with inexpensive standard HDMI cable it is possible to achieve excellent results and enhance your home cinema listening experience and get noticeable quality of sound improvement via your audio visual system utilising the available 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 buy. Firstly, usually do not get brainwashed by retail shops that make an effort to sell the eeogzu expensive cables since they would love you to invest as much as possible as opposed to understanding the needs or requirements of your home cinema setup – don’t be fooled.

So what HDMI Cable would 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 should be mainly compared by the caliber of the constituents and manufacture. The Shanling amplifier available manage to focus on the more you may spend the better you accomplish – well stop and you better think again. High quality output of an inexpensive HDMI connector cable gives the same results as spending 10x or 20x more.
