2.0 About your MARS Hybrid Amplifier:
Dared enters a new area
for both new and veteran audio enthusiast alike. Combined with the
latest Class AB Texas Instruments Monoblock linear amplifier with the
exceptional true to life characteristics of the 6N3 tube used in the pre-
amp stage, DARED delivers an affordable yet performing amplifier
with true to life imaging. Its Class AB bridge
-
tied load (BTL), trans-
formerles output configuration provides exceptional impedance b ridg-
ing even at a very low load of 2 ohms. For wireless a CSR 8645 2.4
GHz hi end audio chipset is used to reduce any digital noise and pro-
vide an outstanding performance. The aluminum chassis itself reduces
resonance as well as dissipates heat. An overdesigned power stage
prevents high frequency distortion as well as any crosstalk between
the high and low voltage signal paths. With a preamp output, MARS
can also be the bridge between vintage audio equipment with modern
technology adding USB DAC and wireless connection to Smartphones
etc.. Quality components are used throughout the assembly that
should provide you with many years of listening pleasure. Included in
your component selection, design and fabrication :
•
All wiring used is made of Oxygen Free Copper (OFC) having enhanced
conductivity advantageous to audio signal transmission.
•
PCB using 2 oz copper layer to maintain extreme low resistance and noise
•
Japanese Nichicon high quality Electrolytic Capacitors
•
Gold plated connectors
•
Select 6N3 Vacuum Tube
•
For superior high frequency performance, Non
