Carver M-400 A Cube

摘要

At the same time both marvellous and idiosyncratic, the Cube achieves its designer's aims of delivering economical, inexpensive and abundant power. Drawbacks include: mild RF interference radiation (a supply line filter helps matters here); a gentle buzzing from the magnetic core at idle, replaced by odd spurious grumbling noises and rattles under power (the Cube is in fact cool enough to hide in a cupboard); and a significant response sensitivity to complex and low impedance loading at high audio frequencies. Distortion was satisfactorily low under all conditions, noise levels fine, and generally on essential technical grounds we found little to criticise. The power delivery under programme conditions was very high and should be sufficient for the most demanding load and peak power requirements, and despite the load interaction the sound quality was to a fine standard, well above average for its price and high for its power class. If it suits your system, and in particular if your speakers need and can handle this kind of power, then the M-400 A could well be the answer.
