MANLEY STINGRAY iTUBE (£2695)

摘要

Measured in ultralinear mode, some effort was required in matching Manley's 40W specification. Relaxing the distortion limit to around 3% and hooking the iTube into a 4ohm load, this output was still only achieved by the skin of its EL84 output tubes. In practice a figure of around 2x33W into 8 or 4ohm loads is more realistic with no real increase under dynamic conditions. So the iTube is best partnered with sensitive and relatively easy-to-drive speakers if you are to realise the sweetest fruits of Manley's labour. The amp also operates partially in Class A so power consumption is high at 165W (idle) and 240W (rated output). When not in use. turn it off.
