But LCR RIAA units have drawbacks as well.
These drawbacks are high cost and the
difficulty of impedance matching; the latter
has been the primary hindrance to the
commercialization of this superb method in
the construction of phono stage amplifiers.
However, Allnic Audio manufactures a high
quality LCR RIAA unit and has developed a
600 ohms impedance matching method.
•
For superior signal to noise ratios, the H‐1500
II PLUS is equipped with pure vacuum tube,
high voltage regulation for each channel and
a power supply unit separate from the phono
stage itself.
•
High quality MC Step‐up Transformers with
Permalloy cores are used for the H‐1500 II
PLUS's dual MC inputs.
•
New vacuum tube damping technology – Allnic
Audio's patented "Absorb GEL tube damper"
technology prevents harmful vibrations from
reaching the signal / gain tubes and, therefore,
prevents micro‐phonic noise propagation in the
tubes. The Allnic Audio Absorb Gel damper
technology effectively solves a problem that
plagues most tube amplification systems.
Provided other tube components do not
introduce micro‐phonic noise into your system,
with the Absorb Gel damping system, you will
enjoy a degree of transparent sound that will
surprise and please you.

As are all Allnic Audio products, the H‐1500 II

SAFETY
•
Disconnect the power cord by pulling the
plug, not the cable.
•
Do not attempt any repairs. Do not remove
the units' chassis covers without specific
authorization from Hammertone Audio.
•
Keep the power cords away from heat sources
•
Keep the units away from liquids – do not
allow any liquid to enter the interior of the
units.
•
When the units are moved from a cold to a warm
environment, allow sufficient time for any
condensation to evaporate in both units before
plugging the power supply unit into an AC
connection.
•
Do not attempt any repairs.
•
Do not remove the units' chassis covers without
specific authorization from Hammertone Audio.
