Long Beach, Calif. – Pioneer
Electronics added to its G-Clef line on Thursday, with the introduction of two
stereo amplifiers and two CD players.
The products feature
more efficient power-supply circuitry, making them more responsive, Pioneer
said. All are scheduled to be available this month.
The SX-A6MK2 ($700) and
SX-A9MK2 ($1,500) amplifiers boast a twin mono symmetrical construction,
designed to maintain electrical isolation between both channels from input to
output. The left and right channel amplifiers and high-efficiency power
supplies are totally independent and exact mirror images of each other, Pioneer
The design is also said
to minimize the signal path of each circuit block, providing minimal distortion
of signal quality and clear, equal channel separation.
The SX-A6MK2 has twin EL
transformers while the SX-A9MK2 has twin toroidal transformers — both
reportedly increase available power, prevent signal interference and virtually
eliminate noise at low frequencies. The SX-A9MK2 adds a USB input.
The PD-D6MK2 ($700) and
PD-D9MK2 ($1,500) CD players have Burr-Brown and Twin Wolfson D/A converters,
respectively, along with Pioneer’s Legato Link Conversion PRO and Hi-Bit
Both feature glossy
black designs with blue LCD displays, but the PD-D9MK2 has honeycomb chassis
design meant to help to dissipate vibrations and alleviate jitter. Additional
weight and stability features help to shield optical components from ambient
interference that could cause imprecise sound. The PD-D6MK2 features an
aluminum front panel, while the PD-D9MK2 touts a rigid under-base construction,
TAOC Hi-Carbon composite metal feet and a full aluminum casing.
