Topping Amplifier – Can It Be Far Better Than This..

Total harmonic distortion or THD is one of the more regular little T.L.A.s (or 3 letter acronyms) you are likely to see in many manufacturers specifications. But what exactly is THD, is it all that important and what amount of THD is acceptable for HiFi and AV equipment?

In audio reproduction in between the input stage and output stage of E&T audio rack you will see a certain amount of noise and distortion introduced to a signal. A number of this distortion is made by the circuits and physical elements introducing signal harmonics at double and triple the frequencies in the original signal. These added signals are technically known as Harmonic Distortion. THD is actually a measure of the differential between the input stages from the system and also the audible extra signal at each harmonic. The THD calculation doesn’t think about the relative level of each harmonic. EG: One amplifiers output in the 2nd harmonic may be higher than the output in the 3rd. Another could create equal levels in the 3rd and 5th. The 2 amps would sound totally different yet could have the same measured overall THD.

In many hifi circuits including amplifiers and pre amps you need to expect a worth of less than 1% THD because it is easy to get rid of a substantial amount of THD from amplifier circuits using various techniques. Unfortunately it is actually far harder to avoid significant degrees of THD from being produced by the physical elements of a setup like the Topping DAC. Much higher degrees of THD are typical in cheaper end speakers especially at higher volumes. Speakers with higher levels THD tend to cause “smearing” of audio, and lead to poor imaging and a “muddy” sound. The truth is one should test a component ideally inside the room it is going to be found in and also at a volume level it is likely to commonly be heard at to find out when the product is appropriate for purpose.

Your home cinema system or audio visual system will require a specific degree of cabling to maximise the available sound quality of your system. Therefore you will want to improve your equipment with digital connections to every audio visual component to achieve the best listening experience. The very good news is that you can obtain noticeable audio quality improvements out of your home cinema system through using suitable digital HDMI interconnects (Hi-def Multimedia Interface).

In the following paragraphs we explode the industry biased HDMI Cable Reviews and show you how with inexpensive standard HDMI cable you are able to achieve excellent results and improve your home cinema listening experience and acquire noticeable sound quality improvement through your audio visual system utilising the available digital connections.

Finding the right HDMI cables for your own personel system is a pretty straightforward process and there are a few things to be considered 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 enjoy as far as possible as opposed to knowing the needs or requirements of your property cinema setup – don’t be fooled.

Just what exactly 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 quality of the ingredients and manufacture. The Shanling amplifier available seem to focus on the more you may spend the better you achieve – well stop and you better think again. Top quality creation of an inexpensive HDMI connector cable affords the same results as spending 10x or 20x more.
