Clearer Audio Copper-line Alpha Power-HUB – £65.00+
Hi-Fi World, September 2009
Designed to be "a first class power supply solution for both hi-fi and home cinema systems", the Copper-line Alpha Power-HUB is manufactured
from high quality extruded aluminium, and comes directly hard-wired with Copper-line Alpha Power Cable. The large socket contacts are made
from copper alloy, providing low impedance. High purity large gauge 2.5mm2 conductors are used internally, capable of carrying currents of up to
26A (6000W). A new active filtration mains noise system called Hyperion is fitted, using two high performance capacitors to filter both
common-mode and differential-mode noise, and it's said to allow over 17A (4000W) of continuous current delivery. Status LEDs show that the
HUB is powered and the Hyperion system is active. A new feature called Earth-View constantly monitors ground integrity; should the integrity of
the ground become compromised then the status indicator will go out. There's also the company's Gatekeeper Surge Protection which only
activates when a surge or transient occurs. All three channels (live-neutral, live-earth and neutral-earth) are protected with surge currents of up to
10,000A being clamped in less than 25 nano-seconds, the company claims. Prices start at £65 for a 4-way, including 0.5 inlet cable, and there's
a sixty day money back guarantee.
Sound quality is excellent for such a budget product; I found this compared very well with any sub-£200 power block I've come across. It's very
clean sounding, presenting a satisfyingly 'hash-free' sound in my own room. Treble proved nicely sweet, midband expansive and open and bass
decently tight and propulsive, even if it wasn't quite the most impactful I've heard. Still, an excellent all round product at the price.
