The Tannoy 700 Dual Concentric
Historical Review: Martin Colloms April 1993
Tannoy has made steady progress on the studio monitor market over decades. Medium sized monitors are required to have a performance envelope which reaches beyond the capability of most domestic speaker designs. Low coloration, subtlety and transparency may be the provenance of high quality domestic speakers; the professional monitor must be capable of very high standards in terms of dynamics, 'speed', power handling and loudness as well as outright sound quality. Furthermore it must be highly analytical. It does not have to sound 'nice'; rather it must faithfully reveal both flaws and qualities in the monitored signal source.
Historical: 12 December 1991 review of an early CD player by Martin Colloms
The US company conrad johnson are best known for their classic line of high quality valve/tube electronics which includes the long running, true high end 'Premiere' series. However, this company is larger and more active than you might imagine and has other divisions which generate significant home sales such as Motif - these high performance, non valve products, and also Sonographe, a mid priced line. Sonographe includes speakers and turntables in addition to amplifier electronics and of course, the SD22 CD player, latest version from a series which has been in production for several years now.
