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 said.

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 technologies.

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.
