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 specifications. But precisely what is THD, is it all that important and what degree of THD is appropriate for HiFi and AV equipment?
In audio reproduction between the input stage and output stage of hifi audio rack you will have a certain amount of noise and distortion exposed to a signal. Some 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 called Harmonic Distortion. THD is actually a measure of the differential between the input stages from the system as well as the audible extra signal each and every harmonic. The THD calculation doesn’t consider the relative degree of each harmonic. EG: One amplifiers output on the 2nd harmonic might be greater than the output in the 3rd. Another could create equal levels at the 3rd and 5th. The two amps would sound completely different yet could have the same measured overall THD.
In most hifi circuits including amplifiers and pre amps you need to expect a worth of under 1% THD since it is relatively easy to eliminate 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 elements of a setup such as the Topping DAC. Higher degrees of THD are common in cheaper end speakers especially at higher volumes. Speakers with high levels THD tend to cause “smearing” of audio, and lead to poor imaging and a “muddy” sound. The truth is you need to test a component ideally within the room it is to be used in as well as at a volume level it is likely to commonly be heard at to find out if the method is acceptable for purpose.
Your property cinema system or audio visual system will demand a particular degree of cabling to maximise the available quality of sound of your system. Therefore you should improve your equipment with digital connections to each audio visual component to get the best listening experience. The particular great news is that you can obtain noticeable sound quality improvements out of your home cinema system through using suitable digital HDMI interconnects (High Definition Multimedia Interface).
In this article we explode the industry biased HDMI Cable Reviews and demonstrate how with inexpensive standard HDMI cable it is possible to achieve excellent results and improve your home cinema listening experience and get noticeable quality of sound improvement via your audio visual system utilising possible digital connections.
Choosing the best HDMI cables for your own system is a fairly straightforward process and there are some things to be considered before buying. Firstly, usually do not get brainwashed by retail shops that try to sell you the eeogzu expensive cables since they would love you to enjoy whenever possible instead of understanding the needs or requirements of your home cinema setup – don’t be fooled.
What exactly HDMI Cable would be best designed for my home cinema system?
Firstly, the essential principle behind HDMI is always to transmit uncompressed digital data via 2 interfaces and digital data cables needs to be mainly compared by the quality of the constituents and manufacture. The Shanling amplifier available seem to focus on the more you would spend the greater you achieve – well stop and reconsider. Top quality manufacture of an inexpensive HDMI connector cable affords the same results as spending 10x or 20x more.
