  • A great amplifier is getting greater
    We are proud to introduce PHAntasy II, the evolutionary version of PHAntasy, the first creation of Phatlab Audio, is renowned for its unprecedented sensational sound quality and well balanced with driving capability. Its novel single-ended topology and unique high quality output transformers are crown jewels inside. After PHAntasy, we have created products with different characteristics and gain further experiences in serving ear/headphones and amplification technology. PHAntasy II is a logical evolution to preserve all the beauty of original PHAntasy while meeting the evolution and progress of audiophile society.

    4.4mm balanced phone jack
    For tens of years, the specification of phone jack is steady, though there are proprietary terminals used by some manufacturers for balanced output. They is never a de-facto and reliable standard well accepted by the industry. Until the 4.4mm jack is released, we see a promising physical implementation that is reliable enough and well accepted as next generation output jack. By applying the new balanced jack, PHAntasy can serve headphones with quality cable and minimum contact resistance to ensure robust sound quality. In addition to 4.4mm balanced jack, a legacy 3.5mm single-ended output is provided for best convenience. While user is advised to use only one of the outputs at a time, it is to ensure the proper loading impedance in single-ended topology.

    Improved Nickel core output transformers
    It is well known that output transformer is the spirit of single-ended amplifier. However, there are challenges to design transformers for small portable chassis. Among them, the high wiring resistance is biggest challenge. The resistance is in series with headphone and consumes output power. It lowers the effective power into loading. In PHAntasy II, we struggle to increase the wire gauge by two and reduce over 20% resistance.

    Double the capacity of power reservoir
    We are not talking about the battery capacity because 8-hour operation time is satisfactory to most users. It is the immediate capacitance right before amplifier high rail. It is critical to have plenty of power capacity for a class-A amplifier. In PHAntasy II, we rearrange the components placement to increase the board size for more capacitance and revisit physical PCB layout to further minimize impedance and effective capacitance.

    Super linear circuitry
    The sensational performance of vacuum tube might be rooted in its higher 2nd harmonics output, while excessive mix-up of harmonics from different stages will muddy the sound. By leveraging the development of Phantom, we are aware of the lower distortion from surrounding circuitry will faithfully preserve the resolution and liveliness of music without losing the magic of tube sound. By applying the same super linear topology, the performance of PHAntasy II is manifested in its purer music presentation.
