Tom Evans Linear B Mk3
The new Mk3 power amps both have 'user variable feedback' a multi position switch sited on the rear of the amps just below the bespoke 'purest' Copper binding posts.
Monoblocks sold as a pair.
PRODUCT DETAILS
Both amp designs have a low enough output impedance when switched to zero feedback to drive a range of impedances that will cover and drive pretty much all speaker designs.
Used in this way they will provide the listener with an accurate reproduction of the recorded event but without the usual dynamic compression and loss of finer detail caused by feedback itself.
Both designs will also match the varying impedance of your loudspeakers across frequency assuring a flat in room frequency response (unlike all transistor power amp output stages!).
Just look for an impedance plot of your loudspeakers, you would be surprised what you find as it wont be flat and may well dip to below half the quoted 'nominal' impedance. This forces any transistor power amp to more than double the power - as an example. you’ve almost certainly read where a transistor amplifiers output is listed as: 60 Watts into 8 Ohms, 120 Watts into 4 Ohms.
The mono chassis differential output Mk3 Linear B's have 4 times the power of the stereo chassis and will drive a minimum of 3 Ohm loads when switched to the zero feedback position.
