There is only one way to build a multi channel power amplifier and that is, a monoblock. Here each channel has its own transformer and power supply and its own discrete circuitry. Some manufacturers use a single transformer with each channel pulling power from it as they need it. The well known American manufacturer Carver, amongst others, makes a virtue of this compromised solution and calls it ‘power steering’ as if the amplifier was doing something as opposed to responding to the demands of the individual channels. Tag McLaren designed the 100x5R from the start as a ‘no compromise’ solution so that none of the individual channels would be affected by what was happening on any of the others, allowing the full impact of a film to be reproduced. They used the best components available and housed them in an aluminium chassis and followed this by rating the amplifier at well below its real world power ability. Time and again reviewers were amazed by the measured power output far exceeding the specs. A typical example is shown below: (testing the av processor AV32R with five channel amplifier 100x5R) "In our listening tests the 100x5R/AV32R combination was one of the very best we have ever tested. Such powerful, low frequency extended, yet transparent, spatial and relaxed systems are very rarely found. Particularly, the spatial information is wonderfully accurate and sound locations are easily detected, revealing even the most complex sounds with ease. We have never seen such identical frequency response from all channels in our AV-laboratory. The signal to noise ratio is extraordinary. And in terms of amplifier output power the 5x145 watts into 8 ohms, respectively 5 x 235 watts into 4 ohms. Audiovision I am offering for sale this Tag McLaren 100x5R amplifier in black. The amp has no marks that I can see and comes with its original packaging. The price is £650 and is cash on collection from near J25 of the M25. At a later stage I may be the listing the accompanying AV32R (Dual Processor) version. Please Note: If you are thinking of making any price comparisons with other previously sold 100x5R’s I’d be grateful if they can be made on a like for like basis. This unit was hand delivered to Kevin Green at ‘Audiocellar’ and was serviced by him. This included new caps where necessary and at the same time the individual channels were re-biased. Since its return it has been used on 3 or 4 occasions to test and then been re-boxed. The new owner will not be disappointed. Regards Parmenion p.s.
