24.10.2022 08:20 | ~1 minute read
hARt Lab Tune Two is a new High End preamplifier with on-board digital-to analog converter, streamer, phonostage and headphones output. According to the company, the model uses best volume attenuation technology and enhances the audio signal with direct tube output (single Class-A tube stage amplification) or hybrid output.
The streamer stage can run wireless, ethernet connections or via USB drive. Optional DAC module has a mode switch (bit-perfect or upsampled) and uses dedicated clock system. Headphones output based on tube-MOSFET Class-A hybrid scheme, and phonostage (optional) works in Class-A and suitable for MM and MC cartridges.
hARt Lab Tune Three, stereo power amplifier, based on Dual Mono configuration. A unique scheme is used here - tube voltage amplifier with a MOSFET impedance amplifier with zero negative feedback. As a result, the company promises incredible sound quality. Full specifications of the amplifiers will be presented soon.
