Taga Harmony PC-7000 (2025) silver
Complementary product
Overview
The PC-7000 from Taga Harmony is a power conditioner designed for audio and video setups. This 8.4 kg unit features a 200 W toroidal transformer and dedicated filtering for eight Schuko outlets arranged into four groups, tailored to different types of equipment. It also includes an analog voltmeter, a phase detector, and surge protection up to 4500 A.
Design and construction of the PC-7000
The PC-7000 uses a black metal chassis measuring 11 cm in height, 43 cm in width, and 33 cm in depth once the feet are installed. At 8.4 kg, it has a reassuringly solid feel. The front panel houses a backlit analog voltmeter, a phase detection indicator that lights up red in case of inversion, and a main power switch that controls only the four switched outlets.
On the rear, eight Schuko outlets are divided into four groups of two outlets each. This arrangement is deliberate: each pair receives specific filtering suited to the type of equipment it is intended to power. The input cable uses an IEC C14 connector, allowing it to be replaced with a specialized power cord if desired.
At the heart of the unit is a 200 W toroidal transformer whose role is to isolate audio sources from line noise. This transformer is topped with a shielded aluminum cover to protect it from external electromagnetic interference. The internal wiring uses oxygen-free copper (OFC), a material that minimizes electrical resistance and optimizes conductivity. Each outlet group has its own oxygen-free copper inductors, while class X capacitors handle the filtering.
The maximum total load reaches 14 A, or 3450 W, with noise reduction between -10 dB and 55 dB depending on the frequency range (2 to 100 MHz). Surge protection handles peak currents up to 4500 A for a very brief duration (8/20 µs), with a maximum clamping voltage of 775 V and an energy absorption capacity of 140 joules.
A filtering system tailored to each type of device
The division of the eight outlets into four distinct groups is one of the PC-7000’s key strengths. This segmentation reflects a precise understanding of the differing needs of hi-fi and home cinema equipment.
Group I (Switched - 3 A max): These two switched outlets are intended for digital accessories. They benefit from filtering suited to devices that generate electromagnetic interference while remaining sensitive to clean power.
Group II (Switched - 1 A max): This second pair of switched outlets specifically targets audio sources (CD players, network players, DACs). The 1 A limit aligns with the typical consumption of such devices, while the filtering prioritizes signal purity.
Group III (Unswitched - 5 A max): These unswitched outlets, which remain powered even when the front switch is off, are suitable for preamplifiers and accessories that need to stay energized. The filters in this group are sized to handle higher currents.
Group IV (Unswitched - 5 A max): The last pair, also unswitched and supporting up to 5 A, is intended for power amplifiers. The filtering is tuned not to compress dynamics while still cleaning the power.
This organization into independent groups aims to prevent a particularly noisy device electrically from contaminating other equipment connected to the same conditioner. A Class D amplifier, for example, can generate high-frequency interference that, without separate filtering, would propagate to more sensitive audio sources.
Power grid protection and monitoring
Beyond filtering, the PC-7000 incorporates several protection and monitoring features. The analog voltmeter on the front lets you check the stability of the supply voltage in real time. This visual indication is useful for spotting abnormal variations that could affect performance or the longevity of your equipment.
The phase detector, indicated by a status light, identifies a possible inversion of phase and neutral in the electrical installation. When the indicator lights up red, a simple polarity switch on the back allows you to correct this issue without touching the fixed wiring of the home. This function may seem anecdotal, but an inverted phase can sometimes create ground loops or background hum in audio chains.
Surge and spike protection activates automatically. The system can absorb peaks up to 3000 V (at 10 mA) and limit the voltage transmitted to connected devices to a maximum of 775 V during a fast transient. The maximum dissipable energy reaches 140 joules, which corresponds to standard protection against storms or occasional grid faults, though it does not match very high-capacity dedicated surge protectors.
The conditioner’s own power consumption remains negligible: less than 0.1 W at idle, plus 0.2 W when the voltmeter backlight is on. This energy frugality allows you to leave the PC-7000 powered on at all times without significantly impacting your electricity bill.

Frequently Asked Questions
Should you plug all your devices into the PC-7000, or only certain components?
The logical approach is to prioritize sensitive audio sources (DACs, CD players, preamplifiers) and noisy digital devices that gain the most from filtering. Power amplifiers can also benefit from more stable power, but some very high-end systems prefer a direct wall connection to preserve maximum dynamics. Ideally, test different configurations to find what works best for your setup.
Can the toroidal transformer limit the available power for a demanding amplifier?
The PC-7000’s 200 W transformer serves an isolation role rather than supplying raw power. The outlet groups accept up to 5 A (i.e., 1150 W at 230 V) for amplifiers. This is sufficient for most living-room amplifiers, but a very power-hungry monoblock or a high-power Class AB amp could theoretically run into this limit during large musical peaks. In practice, it’s rare for this to become audible in a domestic setting.
Are the voltmeter and phase detector actually useful day to day?
The voltmeter provides reassuring visual feedback on grid stability and helps identify abnormal variations that might otherwise go unnoticed. The phase detector is mainly useful during initial setup: once the correct polarity is set using the dedicated switch, the indicator stays off and you can forget about it. These features aren’t essential to the conditioner’s operation, but they make troubleshooting easier if issues arise.
Can the supplied power cable be replaced with a specialized model?
Yes, the IEC C14 input on the back of the PC-7000 accepts any compatible power cable. Taga Harmony also offers its own range of mains cords (TPC and STPC series) designed to pair with its conditioners. Some users report subtle improvements when replacing the stock cable, while others hear no difference. As is often the case in audio, results depend on the system and the listener’s sensitivity.
The front switch only controls four outlets: is that a limitation?
It can be surprising, but this design isn’t a flaw. The four unswitched outlets (Groups III and IV) are intended for equipment that benefits from staying powered: preamplifiers, amps that need warm-up time, audio servers. The four switched outlets (Groups I and II) let you cut sources and digital accessories with a single action. This logic matches real-world use, even if a global switch would offer more flexibility.
What’s the real difference between the PC-7000 and the more expensive PC-5000?
Both models share a similar philosophy with four independent outlet groups, a toroidal transformer, and phase detection functions. The PC-5000 uses slightly different internal components and offers similar specifications. The PC-7000 is a slightly reworked 2025 version, but the performance difference between the two is subtle. The choice often comes down to availability and pricing rather than a dramatic sonic gap.
Does the PC-7000 provide effective protection against storms and power outages?
The PC-7000’s surge protection absorbs spikes up to a certain threshold (140 joules, 4500 A in a single peak). This covers common grid surges and minor disturbances, but it doesn’t replace a modular surge protector installed at the electrical panel in areas prone to severe storms. Likewise, the conditioner doesn’t protect against power outages: for that, you’d need an uninterruptible power supply (UPS) with a backup battery.
