TP-6.5 Series II Signature phono stage represents a significant upgrade and refinement of TP-6.5 Signature. Enhancements include circuit improvements originally developed for the acclaimed TL-7.5 Series III Reference phono stage, as well as a newly designed, more robust power storage system for the active MC stage.<\/p>\n
The original TP-6.5 phono stage complemented VTL\u2019s flagship line stages\u2014the TL-6.5 and TL-7.5\u2014perfectly in terms of sound quality, user interface, and aesthetic design. The new TP-6.5II takes this even further, incorporating VTL\u2019s latest innovations to elevate analog amplification performance to new heights, delivering a significant boost in phono stage performance compared to its predecessor.<\/p>\n
Phono preamplifier utilizes a hybrid JFET\/vacuum tube circuit for quiet operation and features multiple low-noise cascaded voltage regulators and a shielded power supply to deliver an expanded dynamic range. It offers balanced outputs, precise four-corner passive RIAA equalization, and 68dB of gain\u2014all integrated into a single chassis. Extensive loading and gain settings, along with other input functions, are easily accessible via the front panel and remote control.<\/p>\n
One of the key design breakthroughs of TP-6.5 II lies in its power supply section, which utilizes a shunt regulator. This design delivers superior voltage regulation and ripple rejection while minimizing the regulator’s impact on the audio signal\u2014a benefit achieved by reducing the regulator’s gain requirements. The result is a significant reduction in background noise, leading to enhanced stability and improved clarity in the mid-range and lower-mid frequencies. Vocals become more transparent, details richer, and high-frequency extension superior, creating a more lifelike overall listening experience. Notably, the speed and dynamic performance of active MC cartridges are also significantly enhanced.<\/p>\n
Further refinements to TP-6.5 II series stem from the high-capacity, low-impedance power storage utilized in its active MC stage, powered by a system of cascaded voltage regulators and capacitance multiplier circuits. The resulting stable, low-impedance power supply effectively prevents power supply ripple and other noise from interfering with sensitive MC signals. Novel gel capacitor technology\u2014enabling higher capacitance values \u200b\u200bwithin a more compact form factor\u2014was pivotal to the breakthrough performance of TP-6.5 II\u2019s active MC stage, directly contributing to significantly lower noise levels and exceptional handling of ultra-low-output cartridges.<\/p>\n
TP-6.5II also offers a high-quality transformer-based MC step-up option, providing low-noise MC step-up amplification or serving as a secondary MC stage. This second MC input replaces the standard MM input found on TP6.5, utilizing the original MM input circuitry to connect the MC step-up transformer.<\/p>\n
Incorporating a step-up transformer not only provides an appropriate load for cartridges with very low output but also offers flexible compatibility with various cartridge types; in certain instances, a cartridge may deliver significantly better sound quality when paired with a transformer rather than an active gain stage. Furthermore, the transformer allows the cartridge to operate directly into the transformer’s own load\u2014bypassing a standard load resistor\u2014thereby preserving as much of the usable signal as possible.<\/p>\n
Input switching occurs only after signal amplification, avoiding the signal loss inherent in switching the delicate MC signal directly from the cartridge.<\/p>\n
This option offers maximum flexibility for handling MC cartridges and, since both inputs can be connected simultaneously, accommodates multiple tonearms and MC cartridges.
