The device is designed for use with a single audio or AV system component. Audiolab recommends that it should be used with the integrated amp or power amp component within your system to obtain the most significant benefit. I/O's are not decoupled so in almost any ofthe designs I have scrutinized, interconnects shield noise is landed right on to the PCB instead of grounded to chassis. The stray infects the so delicate 0 volt ref voltage to numerous IC's including the DAC chip. Do not take just my word for it, it is a friend of mine, studio technician, Master of Science educated, at least 40 years in the profession, who rebuild DAC's like dCS, but also cheaper versions like Topping D90SE, who claims that ground ref is is a design flaw in it self as are many other areas. The ground is then also challanged by the standard procedure of soldering e.g. pin1 but also shields in USB's, I2S UI, etc in the PCB. The PCB ground should not be used to land noise from cable shield in my opinion. So when decoupling, you should be able to trust the ground you decouple to., but you cannot. One thing so often overlooked is the use of filter and buffert electrolythic caps. They are in the analogue domain often soldered i pairs from the positive and negative to the ground, instaed of caring for the ground by having one twice the size directly between positive and negative only. The filter caps for purely decoupling is wired equally. Why? Some brands use local regulators some do not. In my opinion all voltage regulators should of top class with a few microvolts ripple if any, and locally, with a large buffer, zobel and decoupling almost at the same pin as it is designed to feed. Hifi grade el caps is a myth. The modern 105 degree offers in general better life expectancy and radically lowered internal losses for decoupling.

While studying various designs I stumbled across a TEAC DAC, that I personally found interesting as it took a grip of the dirty USB cable shield. It lands the USB port at separate pcb, hard coupled to chassis by a screw and just millimeters from the port, minimizing the lead reactans, the entire PCB is grounded to chassis. This is an example of a good design. Others in that DAC could be questioned in my opinion. Could not see, e.g. any signs of a grounded lead out from an electrostatic shield in the transformers. Calling it a "power strip" would not do it justice. According to the manufacturer, Chord Company's Master M6 and Studio S6 power distribution units, called PowerHAUS, can do much more than ordinary or even high-quality power strips. There is a very slight hum coming from my turntable. I only know this, as when I approach my hifi to change records. I can hear it. I've never noticed it when playing music. With a quieter mains signal being feed to your amplifier, the whole system benefits. A quieter amp means less distortion relayed to other components, helping reduce distortion and enhance music dynamics.Prices valid in stores (all including VAT) until close of business on 29th November 2023. (Some of these web prices are cheaper than in-store, so please mention that you've seen these offers online.) A quite cheap and not very sophisticated filter design, offering a substandard DC-filtration, unless the reqtifier bridge is not spec'd with higher forward voltage diodes. The decoupling is very rrudimentory as well and will do some good, but since no resistor loads are implemented it will not cancel possible resonances.

Additionally, this dual-action device is said to boast a high-performance audio class filtering circuit that removes RFI/EMI contaminants from the mains supply. We are informed that this reduces both differential-mode noise (exacerbated by cheap switch-mode power supplies used by many home appliances) and common-mode noise (aggravated by airborne interference from phones, Wi-Fi networks and Bluetooth).

The Polish brand Ferrum launches the "Power Splitter", a matching accessory for the external power supply Hypsos, with which it is supposd to power two devices simultaneously. Audiolab presents its new reference series: The 9000A integrated amplifier and the 9000CDT CD transport aim to impress with new technology and a large display, among other things. The Power Box RS2 Phono promises high-purity "linear" power supply for Pro-Ject turntables and phono preamps at the same time. Would such a circuit affect ambient noise in your room? - absolutely not, unless your transformer is humming and you can hear it! A DC filter would stop that, for sure.
