T he Arcam P49 power amp ( £3,000 ) is reviewed by the Stereophile. The reviewer has long memories remembering the launch of the $217 A60 Integrated amp ( £200 as I remember it !).

T he Auralic Taurus Pre Amp is partnered with its natural power amp the Auralic Merak Mono Block Power Amps which use class D mode to run coolly but still offer 200 Watts per channel into 8 Ohms (400 Watts into 4 Ohms by the way so respectable power)from small enclosures.
