Tube Line Preamplifier
The
AKSA TLP is a unity gain, vacuum tube line pre-amplifier module to couple
input sources to the AKSA power amps.
Its purpose is strictly to add that indefinable tube romance to a spectacular,
solid state amplifier. It is a very real alternative to a large, expensive
and costly to maintain tube amplifier. Like the AKSA power amps, the TLP
is designed with premium sonics in mind. It offers an easily configured
volume control, tube magic, and permits use of very long interconnects
whilst preserving full compatibility with the AKSA power amps. The TLP
adds that mystical "warmth" associated with tube audio equipment,
and turns wonderful sound into sublime music.
A Nirvana upgrade using carefully selected premium components and a change
of circuit dimensions is offered for those audiophiles who wish to take
this innovative design to the max.

The TLP is interposed between the line source and amplifier. Its sole
purpose is to enhance the sonics of the system, as it offers no gain.
The TLP adds that indefinable 'tube sound' to SS muscle and slam. It softens
the AKSA without costing detail or slam, and adds a marvellous quality
of humanity to recorded music, particularly vocals. Music has emotional
impact; it tickles our soul, and this is what the TLP brings out in Spades.
It must be emphasized that THD is not a particularly relevant specification
with tubes; these figures are normally much higher than solid state circuits,
and reflect the fact that the tube operates in single ended mode without
negative feedback. Of far greater significance is the high order distortion
composition, which is negligible with tubes and primarily responsible
for their very musical presentation.
The TLP is a premium high end design, and with matching sonics. It compares
more than favourably with the true high end US tube preamplifiers, and
offers an incomparable sonic overlay on all musical material regardless
of source.
