From a measurement perspective this Polish cable reduced noise by nearly 100%. This achievement was a personal record only matched by the PS Audio Powerplant Premier (not its successors P5 or P10) and Cammino Harmonizer power conditioning boxes. We suspect that the older PS Audio device used a step-up transformer to make it 240 volt compatible and thus applied galvanic separation. Anyway, no other power cord has matched the filtering potency of this Polish cable.

Time for musical duties. Over the years we’ve learnt that source components are prime candidates for power anomaly cures. Therefore we plugged the Allbit into the XXHighEnd PC and accompanying Phasure NOS1 DAC, making sure of correct power polarity [M&H live in Holland whose power-plug standard is the symmetrical two-prong Schuko which can be inserted two ways – Ed.]. Downstream a pair of Ncore 1200-based Hypex monos fed our 100dB Pnoe hornspeakers. Once the PC booted up awaiting our ‘play’ command, we raised the digital volume control higher and higher to asses the amount of noise from the speakers. When we reached -4dB there still was no sigh, hiss or hum coming from the speakers even with the ear almost touching the AER driver’s whizzer. Yes, we finally arrived at a super quiet high-efficiency system where all ground loops have been banished. Clearly the Allbit’s protective earth filtering feature did its magic very effectively.

With the volume clicked down to a sensible setting, it was play time. Should it suffice to say that the first listening session took a few hours? The transformation our system underwent came down to a super quiet background which enabled even the softest details to be rendered unobscured. The sense of a recording’s space was uncanny due to its sounds’ decay times being considerable longer than ever perceived before. Not only soft details now came to the fore above the undetectable noise floor. Transient separation was uncanny too.


Have you ever tried to count the rivets on a sizzle cymbal? If so inclined, you could do now. Instead of a single swooshing sound, there was an irregular combination of individual ts, ts, ts. Crash cymbal? Whack and over. In the lower frequency department things had changed as well. For a single-driver hornspeaker the Pnoe is not really bass shy but when we feel like it, we add the Zu Submission for the lowest octave of ambient, psytrance and fare where 20Hz is really present. With the introduction of the Allbit there was change here too. At first the low frequencies appeared to be somewhat leaner, less intense. But then the notion arose that the bass had actually intensified and was far more enveloping. The previously full and rotund bass had actually been the result of added noise like the quasi euphony certain tube amplifiers are admired for. Now the truth was out there.
