CES & THE Show 2013 Hot Product
Vladimir Lamm updates his products infrequently and
releases new products deliberately. He completed the design work for his LP1 Signature
phono stage ($32,790) years ago, but only now is it a commercial reality, perhaps because
of its ambitious arrangement. Its three chassis comprise a pair of tube-rectified power
supplies -- one for each channel -- feeding a dual-mono phono stage.
The mirrored dual-mono layout of the LP1 Signature
is easy to see. There are three inputs: two for moving-coil cartridges and one for
moving-magnet. The two moving-coil inputs are slightly different: one is meant for very
low-output cartridges, providing 71dB of gain along with a low 30-ohm input impedance, and
the other uses the same step-up transformer as Lamm's LP2 Deluxe phono stage and provides
59.7dB of gain.
Unlike Lamm's LP2 Deluxe phono stage, loading and
capacitance with the LP1 Signature are adjustable in five steps via banks of
internal switches. |
