If you need a subwoofer that will be a good match for bookshelf-sized (or smaller) speakers in a small room you owe it to yourself to check out MJ Acoustics’ new Pro50Mk2.
The Light in the Dark (LITD) power amplifier from Einstein Audio has to be one of the most gorgeous components extant ...  Let’s just say it’s all the chrome gloss black and jutting transformer protrusions. Perched together on superb Finite Elemente racks these components make a statement that’s an industrial designer’s wet dream.
Rogue Audio’s three founders Mark O’Brien Phil Koch and Mark Walker formerly worked for Lucent Technologies which is an integral part of Bell Labs one of the heaviest hitters in the field of high-tech electronics. So it’s something of a surprise that the company has established a formidable reputation for building valve amplifiers!
What the hell is a Supercharger? More importantly what the hell does it do? Perhaps even more importantly: ‘Do you need one?’
Valve amplifiers are heavy. But 38kg? When the courier delivered Jungson’s DA-88Ti in its wooden crate I tried to move it with my aluminium trolley. One buckled trolley later I used my steel trolley instead. Opening the crate was like solving a Chinese puzzle. If it hadn’t been for the instructions provided by Minjie Lin of MFL who distributes Jungson in Australia I would not have discovered the concealed slats underneath the crate that need to be removed before it could be opened.
The Brits have a funny idea as to what constitutes a ‘super-power’ amplifier. I guess that when many of your country’s most famous amplifiers have power outputs of less than 50-watts per channel any amplifier with a power output above this figure is considered to qualify
Short on fascia long on abilities the latest CD and amp pair from the UK’s Cyrus proves both versatile and impressive.
Jungson’s JA-88D looks like a power amplifier but it’s not. It appears that Jungson was caught out by a high consumer demand for integrated amplifiers at a time when it was primarily producing separate pre and power amplifiers. The company judged that the fastest way to get a product to market to satisfy demand was to build preamp circuitry into one of its existing power amplifier chassis.
The PM7003 is very similar to the highly-awarded PM7001KI in that it too uses completely symmetrical circuitry and benefits from the use of Hyper Dynamic Amplifier Modules (HDAMs) which use current feedback rather than voltage feedback to enable greater dynamics particularly when the amp is driving speakers whose impedance drops below their nominal value.
Although it’s technically just a variant of a conventional power amplifier (indeed it can be used as a power amplifier if you like) Musical Fidelity refers to the 750k (and the 550k) as a ‘Supercharger’ because its raison d’etre is that it should be added to an existing audio system to ‘turbo-charge an existing power amplifier rather than to replace your existing power amplifier.
