Useful tips for the sound optimization of your hi-fi system:
Basics in outline .....

We would like to wish you a lot of pleasure listening to your favorite music, but you also want to point out that the right set-up and proper operation of your high-quality music system guarantees you a realistic listening pleasure.
Tips for the right installation of a hi-fi system:
Proper installation and decoupling of the devices make up about 20% of the sound of a system.

The attachment:
The less disturbing vibrations your system is exposed to, the better the sound.
(Nowadays measurable, due to the microphonic sensitivity of the capacitors in the devices.)
Therefore, your hi-fi components should always be housed in special hi-fi racks.
Where this is not possible, one uses special documents (eg from Acoustic Systems, Shun Mook, PMR Jungblut, etc., to borrow for testing without obligation!
Also special metal cones (Cones) help to derive or dampen resonances.
The horizontally positioned components should also not touch directly.
A separate installation is important to prevent interference between the devices.

The speaker:
When stereo, the speakers form an equilateral triangle with the listening position and the tweeter is located approximately at ear level.
Boxes should never be placed directly on the floor, as the vibrations of the speakers interfere with the sensitive electronics.
Floor boxes are therefore always wobble-free and horizontal on spikes (usually supplied steel tips, or better) to ask.

The parquet floor is protected with special washers, which are available in different versions.
Highly recommended are the so-called skeets from Linn:
The spikes are stuck in thick metal discs and the boxes can be easily moved.

Order here immediately possible:
https://hifiteamshop.at/products/linn-skeets-lautsprecheruntersetzer-set-mit-8-stuck
Shelf boxes should be placed on special speaker stands, shake-free and horizontally, at the bottom and top of which spikes are again located.
Shelf boxes standing directly on the shelf are decoupled with 3 separate spikes per box.
The locknuts of the spikes should always be tightened.

If the speakers are suitable for so-called bi-wiring operation, this possibility should also be used; if not, buy special bridges, these sound much better than most of the supplied metal bridges. Try out !

The distance to the wall: Generally speaking, most loudspeakers should not be placed directly against the wall. This does indeed produce more bass, but this is too inaccurate in standing speakers. In addition, the space would leave something to be desired when near-wall installation.

A distance of 50 cm to 1 m from the back wall, but also from the side walls is usually sufficient.
Listening and trying out is essential here!
The cables:
Cables make up about 20% of the sound of a system,
They are an important link in the chain.
The speaker and device connection cables (cinch cables) must be considered as separate components and not just as necessary accessories.
The system is like a chain, this is never better than the weakest link .....
With the right cables, you can bring your system to top sound level.
Therefore, please leave the supplied cables in the device packaging and opt for higher quality.
Over many years of trials and comparisons, we've developed several RCA cables in affordable price ranges that also enhance your system's 2 rating: Just ask for the hi-fi team cables.
Each high-quality cable also has a signal direction, which must be observed when connecting.
In order to avoid possible interference, the cinch and power cables should touch as little as possible.
Also note that the speaker cords must be the same length.
Of course, we also provide various cables for you on a trial basis.
Most often, the weakest link is the cable, with speakers around Eur 1000.-Box cable to Eur 2.- the meter .........
The second most frequent source is, for example, boxes for EUR 2000.-, but a CD player for EUR 199.-; You have to hear that first, to believe what was done wrong here ...
The power supply:
A clean and stable power supply contributes significantly to the sound improvement.
If possible, replace the supplied, cheap industrial power cable with a special hi-fi power cable.
Highly recommended in this context are high-quality hi-fi power strips with special connection cables, phase markings and a hand-soldered interior.
Very good and cheap are these here:
https://hifiteamshop.at/products/netzverteiler-6fach-jentech-mit-1-5-meter-kabel
Also check with the help of a phase tester whether all components on the power strip are actually operated with the correct phase position.
Also, the connection order of the devices on the power connector strip must be observed, since the devices influence each other.
The first connection option is located where the power cable leads into the connector strip. Here you should connect your main music source (if available the turntable otherwise the CD player), then the preamp, then the tuner or CD burner, then the TV or DVD player and finally the integrated amplifier, receiver or the power amplifier.

Tips for the right operation of a hi-fi system:
Once you have set up your system perfectly and given it a little warm-up, especially with tube sets, you can relax and enjoy your favorite music.
Please note, however, that each NEW system requires at least 48 hours to "load in". Only after this so-called start-up time you can expect maximum sound performance. Delight in the great space, the rhythm and the plastic locatability of the musicians - simply the great live atmosphere of your system. For all "technical love", the music should always remain in the foreground. To enhance the music experience even more, we present you some tips from practice.
Check again and again the wobble-free installation of your loudspeakers.
Every six months, carefully tighten the mounting screws of your loudspeaker chassis.
In order to obtain the optimum conductivity of the signals, you should periodically clean all contacts on the device sockets and cable plugs (connection and power cables) with alcohol or special contact agents. The simplest method: just a few times off and on again.
Always keep your CDs clean and avoid scratches: Always keep the CDs in their cases and keep them clean regularly with a special cleaning agent (eg Audioclean) and a special cloth. Even newly purchased CDs sound better after a special cleaning because they are freed from production release agent residues.
By sanding and painting the edges of the CD, the light of the laser scanner is reflected better, resulting in more liveliness and a rounder sound.
Crackle your beloved LPs? Here, the LP-washing on a special LP washing machine and the insertion into special plastic inner sleeves helps.
There are still a lot of possibilities for improvement - especially for the "profituner". We, the hi-fi team, follow every new development and ruthlessly separate alchemical psychotricks from real sonic improvements.
It is crucial to take into account all the details: If the speakers wobble, the cable contacts are corroded and a cheap connector strip from the hardware store supplies the system with power, it does not matter if the direction of signal is correct or the system is in the furniture cabinet. You will not notice a difference!
Power supply is sound supply:
Introduction
While sound differences due to the power cords and power strips were still heavily denied a few years ago, it has now come to the realization that the "right" power supply can bring up to 30% sound gain. Of course, the hi-fi system also works perfectly with "normal" electricity. However, the full sound potential can only be exploited with the "right" power supply. Rule of thumb: The higher the quality of the devices, the higher the quality of the power supply.
With this article we also try to explain to the technically less well-versed music listener why the power supply is getting more and more important and that has nothing to do with imagination or moneymaking of the manufacturers.
Potential differences
All hi-fi devices must be operated with the same mains voltage. Differences in the network potential cause differential voltages between the individual components, which subsequently lead to equalizing currents that enter the signal lines between the individual devices and thus adversely affect the signal transport. The result is sound and image impairments.
To ensure a uniform network potential, all hi-fi devices (including projectors or subwoofers) must be powered from a single, high-quality connector strip, which is powered by a single wall socket. Only in this case there is potential equality for all devices, there are no equalization currents and the signal works in the same cycle.
Ideally, all connection cables (power and equipment connection cables) should be the same length and of the same construction or quality.
However, this can not be achieved in practice.
In addition, the devices themselves cause potential differences due to their different power consumption, depending on the playback volume.
The goal of a good power supply is therefore "only" to keep differences in the mains voltage as low as possible.

Contact resistance
The contact resistances of the mains plugs and the resistive and inductive resistances of the power cables or power strips must also be kept as low as possible in order to ensure the best possible current flow. Here too, voltage drops can occur, which again become noticeable as differential voltages between the components. Therefore, it is important from this point of view to use high-quality power strips and power cords, but also high-quality wall sockets.
Again and again, the following question is asked: What good are power strips and high quality power cord when the power itself is already exposed by the many contact resistance and inferior wiring between the house distribution and system disturbances? Answer: This voltage drop does not work as a harmful differential voltage because all devices are affected together. This sound impairment is much lower, because it occurs as a "Gleichstörung". The better power supply is primarily intended to eliminate interference that the devices inflict on each other.
RF interference
Disturbances in the high-frequency range (HF) are disturbances in the environment of the hi-fi system, which can have a fatal effect on the sound pattern. These disturbances are omnipresent and serve, for example, for the transmission of messages. The main point of attack of these disturbances concerns the hi-fi devices themselves and their cabling (signal and power cables) that act like antennas. Therefore, not only computers, televisions, refrigerators, dimmer switches, etc. are to be regarded as wired network polluters - even those of the neighbor - but also the line-bound HF interference. While these disturbances are very strong during the day, they decrease at night and on weekends. This also explains why hi-fi systems sound different at different times of the day.
These disruptive potentials are rather low in rural areas, but are rapidly increasing in urban areas. The disturbances intervene negatively in the electronics of the devices (eg by shifting the working time), including the sound suffers.
Summary
A good power supply significantly improves the sound of your hi-fi system. The music playback becomes warmer, more intense, more detailed and spatial. In short: a decisive step closer to the "live experience"!
A power supply that is as trouble-free as possible, of course, is just as much a prerequisite for home cinema systems for the best sound and picture reproduction.

Room acoustics, power quality, recording quality, installation and cabling play a much greater role than the devices themselves.
Many of these things are still affecting each other, lots of "unknowns" ... these things can vote their dealer.
A good plant is like a beautiful oil painting: although you can buy the colors, but someone must also paint the picture, that is the job of the dealer.
