We offer you a Topping product pack comprising the Topping D90 III Discrete DAC, a Topping A90 Discrete preamplifier / headphone amplifier and a pair of Topping TCX1 XLR modulation cables (25cm). This pack lets you enjoy the most pleasant headphone listening experience with excellent performance.
The D90 III Discrete balanced DAC from Topping is the parallel to the D90III using a 100% discrete digital/analogue conversion module. Here, conversion is performed by a PSRM module per channel, enabling conversion up to PCM 32bit 768kHz and DSD 512. This DAC also incorporates a Qualcomm QCC5125 Bluetooth 5.1 chip and a 12V trigger input and output on the rear panel. The high-end components found in the previous version, such as the Altera Max CPLD, are also included.
View complete product page of Topping D90 III DiscreteTopping returns with the A90 Discrete, an improvement of the previous A90, this time equipped with discrete components. Both a headphone amplifier and a preamplifier, it incorporates a discrete NFCA amplifier stage capable of supporting most headphones on the market. Its careful design using many high-end components allows it to deliver a rich, clear and transparent sound.
View complete product page of Topping A90 DISCRETETCX1 cables from Topping are high quality XLR male/female cables. They incorporate 6N Copper and Silver plated 6N Copper conductors for perfect signal transmission. Each conductor has a cross section of 0.533mm² (19AWG). The contacts of the connectors are gold plated to maintain excellent conductivity while ensuring high resistance to oxidation. Each cable has a beautiful and robust black and red braided nylon sheath.
