Audioplan speakers for computer
Even if we bend over backwards, nothing comes out of it. If it hits other ripples, they get amplified and grow bigger. Apparently, something like that happened to me and to Dirk Sommer. He was born in in Dortmund, a German city that's well know because of its football team Borussia Dortmund with three Polish football players. He studied electronics for one year and switched to German and Latin language. He graduated in as a high school teacher and taught German language to adults for some years before he began further studies to become a technical author.

Why is clean power so important for perfect music reproduction? After all, any music reproduction is, in fact, not much more than a modulated current. The alternating current for the purpose of supplying private housholds goes back to Nicola Tesla. George Westinghouse acquired the Tesla patents and managed to get the edge on his colleague Thomas Edison with his direct current model.
Today AC is the standard. The electricity that is converted in power plants from heat and movement, can only be transported over such long distances with reasonable amounts of losses in the form of high voltage. Ah, the good old days! The usually ohmic loads — think of the good old light bulb — caused the currents on the outer conductors to more or less balance themselves, the neutral conductor was not unduly loaded, and there was hardly any high frequency.
Nowadays the situation is different. The incoming 50 Hertz sine is — like an amplifier during clipping — flattened at the top and bottom, i. This is measurable as a distortion factor, with higher effort also as a HF coating. Even a notebook and also the stereo system will work as long as the voltage signal on the oscilloscope does not become tri- or rectangular.
However, these more delicate devices have a harder time dealing with excessively polluted currents. There is, also, the interference potential of the HiFi system itself, the rectifiers, the pulsating charges of large capacitors amplifiers , the switching power supplies and sampling rates of digital products.
The basic problem is that, as mentioned above, any reproduced music is basically just a modulated current. Unwanted external modulation can interfere with that. There can be consequential effects.
If you, for example, have a powerful, broadband amplifier that captures a weak high frequency, which is then amplified together with the intended frequency, this can actually overdrive the amplifier if its own bandwidth is exceeded, thus leading to transient intermodulation distortion TIM or even to oscillation.
Conventionally designed power supplies provide little protection against the intrusion of high frequencies. Only very few transformers are capacitively shielded, protected with ferrites or, as with very few manufacturers, the devices are limited in their bandwidth, for example the preamplifier to 50 kilohertz and the output stage to kilohertz. This used to be called amplitude modulation AM radio. Thick neutral conductors and a separate protective conductor would be recommended as the basis for a particularly EMC-friendly power supply.
After the war and to this day, energy suppliers have neglected to lay five-wired instead of four-wired cables as standard, also in order to save copper or aluminum. They therefore only install three phases outer conductors and the neutral conductor in the houses. Until around the mids, it was even quite normal within houses to form a combined PEN conductor from the neutral and protective conductors. There have, for example, been cases of overheating PEN conductors causing fires in electronics stores, as you can imagine especially, in large TV walls where dozens of devices are running in parallel.
Since HiFi systems are also increasingly developing into network-compatible multiroom and streaming systems across floors and more and more digital technology including high frequency, switching power supplies and Class D is being introduced, the problem is even increasing. Homeowners should do their best to start here and treat themselves to the separate protective earth conductor earth , the author has even had a supplementary pole-earthing set especially for the cellar.
Talk about it with your electrician! Tenants will usually have to live with the standard they find, but can also help the power grid with partial TN-C-S retrofits and inductance-free fuses. The power grid should in principle be as low inductance and low resistance as possible.
Then both the susceptibility to interference and the losses are at their lowest, and the thrust is delivered as delay-free and unconstrained as possible.
The usual miniature circuit breakers in the fuse box have an — albeit low — inductance due to their magnetic switches. However, as anyone can imagine, even a large bicycle is slowed down by a small dynamo. Instead, it is preferable to use large-calibre, corrosion-protected fuses as for example the specially developed AHP sound module, which is already available in its fourth generation and makes an audible difference.
The stage image becomes larger, the sound is energized and enriched with additional thrust. DIY store socket strips, clamp terminal connections and cheap wall sockets are the next bottlenecks with resistances that are often ten to times too high, or at least much higher than necessary.
We recommend to replace them with the complex contacts and screwable sockets from Furutech, Groneberg, HMS, Oyaide etc. Some HiFi enthusiasts have deliberately not used a residual current circuit breaker FI or RCD in the circuit of the system because they also fear losses here. Now, at least for me the potential loss of life weighs more heavily. A correctly designed FI switch ensures lightning-fast protection in case of device defects and, yes, it even prevents unintentional or intentional suicide in the bathtub.
If there are children, pets or electronic tinkerers in the household, there is no way around the FI! STEREO has followed its development with great interest and benevolence and will report on it as soon as it becomes available. People who endlessly argue that there are only dozens of meters of cheap 3 x to 5 x 1. In fact, of course, it is a good idea to lay a cable with a stronger cross-section, possibly even shielded, from the control box to the socket in the listening room, because it lowers the overall impedance.
This cable must be suitable for fixed installation and must therefore be NYM-compatible, i. But the most important meter is, in fact, the one directly in front of the devices. This is due to the disturbances caused by compensating currents that flow between the devices on their ground connections and protective conductors.
This is precisely why good materials, contacts and larger cross-sections are essential for accelerating equipotential bonding and why quality power cables make a difference. Since everything is interrelated, not only should the current flow to the system and between the components be improved, but the potential of the cabinets and thus also the interference on the ground, which could impair the signal, should be minimized from the onset.
These potentials, which are nothing more than measurable voltages between device ground and earth, can simply be reduced by one-third just through turning the power plugs. We recommend to have the electrician connect the electrical circuit of your system to a phase outer conductor with as little load as possible such as that of the bedrooms and not to one on which also the solar system or Powerline-adapter is attached.
In addition to checking the polarity, the equipotential bonding can be improved by an additional ground connection.
Already as a teenager, the author has used grounded copper foil to underglue the rack bottoms for shielding purposes. It is also possible to ground the equipment directly. They must NOT be earthed additionally! You can simply attach a standard busbar to the rack or shelf and have the masses, such as the grounding of the rack, tuner and turntable, converge here in a star shape. If, while grounding a component, you suddenly notice an unwanted humming due to a ground loop, just undo it again.
The aim is, after all, to reduce disturbance and not to increase it. Here we see an electromagnetically particularly compatible house installation of the TN-S system with separation of neutral and protective conductor.

HiFi Special: Clean Power
Cheaptubeaudio has had a long history of advocating reasonably priced but excellent tube gears, particularly Singled-Ended Triodes. This Blog however covers a lot more than SET, and is not exclusively tube-related. Cheaptubeaudio prioritizes coverage of unusual and rare gears, particularly vintage ones, on which little info can be found on the internet. Contrary to mrgoodsound's recent post on his HP Laptop's performance, I couldn't have been happier with my current setup with my HP Laptop streaming Tidal and Youtube, which comprise now my main source! Got an old iPhone from my wife for song selection; hooked up the Wifi and I was all set to go! To my disappointment, at once I observed that the soundstage had collapsed, the airiness had completely disappeared and the overall sound had become uninteresting. I had no choice but to put it aside and go back to my Laptop with the Auralic Vega DAC and everything became normal again! Later, based on my poor experience, I suspected the cheap LPS did more evil than good. I switched to the unused cheap stock SMPS. The sound improved but was still inferior to my Laptop!

Lesson Plan
It was the first British speaker to use a metal-dome tweeter, but the bass unit was equally innovative. And as for the later flat-to-the-wall Wafer speakers, based on Philips drive units and measuring just 2in thick, these are surprisingly magicalsounding. Forget metal dome tweeters or metal-coned bass units — ATC prefers more traditional diaphragm materials, with doping applied to quell resonances. And in its smaller speakers it has always preferred closed box to reflex bass loading, in further rejection of fashion. Search form Search. Innovative technology helps the Quadral stand out from the field A mere glance at the Platinum M4 is sufficient to identify it as a Quadral, the bass drivers recessed behind aluminium slats being a clear visual cue, whether the speaker carries the Quadral name or that of its prestige Aurum brand.

Very elegant, but impractical for test purposes: The Lacorde Statement XLRs do not have any markings to identify the right or left channel. Since changing the Lacorde Statement XLR between pre and power amp, and later between pre amp and phono stage the same stunning results were true - in all disciplines a little more of the good and in none, less. But even that could not change my opinion after my first listening impressions while testing the noble cables.
Derek2A3, thanks for your share. Will keep that in mind! For anyone interested, SYD's HK distributor will held an event on 11th June to demonstrate their latest products included the famous Lavardin amplifier and Audioplan speaker. I read that S9 motor operate from V. It stop working under 7.
Perhaps we are being a touch too parochial with home grown products when there is a plethora of products waiting across the Channel that has real merits for adding to an audition shortlist. Arguably, we have the likes of Atoll, Advance Acoustic, Focal, Cabasse and Triangle from France that was instantly recalled from memory without any effort, but I truly struggled to recall any from Germany apart from Audio Physic. Shame on me and I bet I am not alone in this. There are seven power outlets arranged in a radial pattern of six around the perimeter with the seventh outlet located in the centre. The review sample was fitted with seven 3 pin 13 amp UK sockets, but Schuko and other sockets are available to order I believe.
