Reaching new heights with Bluetooth

One must continue to challenge one’s self to continually set new bars of
excellence. The Qualcomm QCC5141 in the UTWS5 brings two major upgrades
compared to the previous generation QCC3020. Not only does the QCC5141 bring a
significant leap in decoding high-resolution music, it also brings a
significant improvement to calls with support for aptX Voice high-definition
voice technology.

Third-gen TWS mode, Lower latency and more reliability

Qualcomm’s third-gen TWS Mirroring as utilized on the UTWS5 effectively
reduces latency and instability for a better experience. Unlike TWS+, TWS
Mirroring allows for seamless switching between being connected to the main
and secondary ear units. This allows for a greater c

The impedance of the three headphone outputs can even be matched to the
headphones in use and the individual sound ideas. A crossfeed function for
creating a sound stage image positioned in front of the head is available on
request. The high-quality mains sections – one digital, one analogue with two
separate torroidal transformers- provide very generous reserves of power.

The digital section is fitted with the proprietary T+A True 1-Bit digital /
analogue converter, which provides an incredible DSD 1024 for Bitstream, and
the T+A quadruple converter with 32 Bit / 768 kHz for PCM. Like all current
T+A DACs the new HA 200 also features a sophisticated and completely separate
decoder architecture for DSD and PCM, ensuring that all digital formats are
decoded to the finest standards.
The design and materials of the case harmonise perfectly with the unique
electronics. The HA 200 is significantly larger and heavier than other
headphone amplifiers, but this is not surprising given the more than 2300
components and the sophisticated HV technology. All the case components are
produced from non-magnetic aluminium, and the front panel is machined from
solid plate material – just like the HV series. Accurate QPPM metering
instruments and a large screen supply important system information, and
provide an accurate indication of operating conditions. The FM8 IR remote
control controls all functions of the HA 200.
We have designed the HA 200 in every respect with no hint of compromise and
without regard to cost, for we had only one goal in mind: musical reproduction
to the very highest standard of perfection.
