Over time Jabra has moved from little Bluetooth dongles that dangle from one ear to sports headsets and is now entering the wider headphone world with straight-up headphone headsets. Or is it that the headphone world is moving towards phone headsets? It's hard to tell...welcome to convergence.
Kentucky manufacturer Thiel has acquired a reputation for the coherence of sound presented by its range of distinctive, sloping-baffle, floor-standing loudspeakers. Designer Jim Thiel gives a high priority to linearity of phase response; as a result, he chooses to use phase-linear, first-order crossovers in his designs, the target response being the combination of electrical and mechanical filtering. As the out-of-band rejection is then only 6dB/octave, it places demands on his chosen drive-units to be well-behaved, not only in their passbands, but also outside of them. In effect, the loudspeaker has to be designed as a whole system, the interaction between the drive-units and crossover being considerable.
This is to-date the best direct-to-disc recording I have heard. For once I can't complain about the high end being shrill or hard. The balances are excellent and the performances superior, with each member of the group getting his chance to show off. Marshal Royal's saxophone solos must be heard to be believed, Everyone present is obviously having a good time making music, which is the way it always ought to be but often isn't.
The Genesis 500 ($650) is the baby brother of Monster Cable's top-of-the-line Genesis 1000 cartridge. It is almost identical in physical appearance, differing only in its use of green body trim (the 1000 sports red pinstripes). All of the functional differences appear to be in the stylus and cantilever. The cantilever of the 500 is a hollow sapphire rod tightly attached to an inner aluminum tube (the 1000 has a diamond-coated boron tube cantilever). Its stylus is a 6µm x 35µm line-contact (3µm x 60µm for the 1000). Monster claims a stylus life in excess of 600 hours for the Genesis 500, more than 1000 hours for its higher-priced sibling.
