Now some three years old as a product, the Cyrus Two is a very compact integrated amplifier, considering its 50Wpc output, as wide but a little longer than an "A4" sheet of paper. (For those unfamiliar with international standard paper sizes, A4 is the same size as the popular RadioShack/Tandy 100/102 laptop computers, if not quite as thick, of course.) The shorter sides of the paper comprise the front and rear panels of the amplifier; the front carries a volume control, a source selector marked "Listen," another selector marked "Record," and apart from…
As I said earlier, the classic Mission 770 was very much a BBC-influenced design, conforming to the British idea of a low-sensitivity, reflex-loaded, "monitor" speaker, though it had excellent upper-bass clarity compared with its similar-sized contemporaries, the Rogers Studio Monitor and Spendor BC1. The top of Mission's 1987 line, the 780 Argonaut has very little in common with the original 770. A tall, attractively styled, floor-standing sealed-box design, it uses two 8.5" polypropylene-coned woofers, with inverted dust caps bearing the…
Having completed the individual auditioning, I put together the components as a system. The speakers remained in the same position in the room, but were now connected to the amplifier via 12 feet or so of Mission speaker cable. This is a conventional figure-eight, multistrand design (651 strands!), insulated with PVC. The copper is annealed, and it is recommended that the cable be used with the "M" of the printed Mission logo nearest the amplifier connection and the "n" nearest the loudspeakers for best results. Initially I used the 780s in single-wired mode with one…

The Artemis Eos Signature's plot of impedance magnitude and phase vs frequency is shown in fig.1. (Logistical difficulties with the enormous Base Module meant that I couldn't measure its impedance.) The speaker is basically easy to drive, remaining above 6 ohms over almost all the audio band. The tuning of the reflex port is indicated by the "saddle" in the magnitude trace centered on 42Hz, which implies reasonable low-frequency extension even without the bass module. Note the slight wrinkles in the traces at 230Hz and 400Hz; these suggest that there are cabinet…

A recent survey of my teenaged nephew and his friends turned up a number of musical trends both predictable and surprising. It sent them into paroxysms of disbelief and laughter when the old-man uncle asked whether they liked any guitar bands, like, say . . . Green Day. Guitar bands, to say the least, ain't cool. Pop-oriented hip-hop artists like Wiz…
