National Audio Show 2013
The original Rock turntable, with its
distinctive damping trough, was created at Cranfield University in the UK, but it was
licensed by Townshend Audio, which has been building the iconic design ever since. The
guys at Cranfield also designed an almost equally controversial tonearm, and over 30 years
later Townshend is putting this into production under the sobriquet Excalibur II. It has
ball-race bearings, but Townshend takes the opposite approach to every other 'arm maker
and selects the loosest examples available in order that a medium-viscosity oil will cover
every surface to avoid metal-to-metal contact. Max Townshend describes this as "a
floating bearing."
The small weight hanging behind the
bearing only adjusts downforce; the mass of the cartridge and the 'arms substantial
outrigger headshell are counterbalanced by a threaded weight between platter and 'arm
bearing. The angle of cartridge is fixed, but the overhang can be adjusted by moving the
armboard. VTA can also be adjusted in the same manner.
If the Excalibur II is as
ground-breaking as the Rock turntable, we could be in for a perceptual leap in vinyl
playback. At £4000, youd expect little else. |
