Project Description

Allnic HA5000 Head Amplifier, £4000

The HA-5000 is Allnic Audio’s pre-preamplifier, or “Head Amplifier”. It is an active, tube based device for amplification of low voltage signals from moving coil cartridges to allow connection of moving coil cartridges to the moving magnet inputs of a phono-stage, such as the Allnic H-3000 or H-1500. The HA-5000 is an active pre-preamplifier, not a “step-up transformer” like Allnic’s AUT-2000, which uses only a transformer to boost the signal from the cartridge.

HA-5000 has two selectable MC inputs (up-graded from only one MC input of HA-3000, many customers have asked to make two MC inputs system). Due to very dangerous “popping” noise when select one MC input to another, no manufacturers(including solid-state) dare to try, which could be amplified thousands times to destroy power amps or loud speakers. Allnic’s ingenious circuit makes it possible to have two MC input without any danger of switching noise.

The HA5000 is used successfully by H1500 and H3000/H7000/H5000 customers and also owners of other decent quality 3rd party phono preamps. Available in silver or black. 2 year warranty on all Allnic Audio Products , 1 year on factory supplied tubes. Part exchange welcome, just get in touch for in-store and home demo.

“When you put the HA-3000 Head Amp in front of the H-3000V, everything on the audiophile wish list gets a boost: dynamics, sound-staging, imaging, dimensionality—you name it.”
Marshall Nack, Positive Feedback
“The HA3000 seems to pressurize each and every note, almost as if it is making space for the note’s reproduction. A whole new language is needed to describe what I’ve just heard”
Allnic US Customer, Audiogon
“the HA3000 nuvistor device has the attack, dynamics, frequency extension, bass grip and detail of transistors but with the spaciousness and tonal capture of tubes. However, it doesn’t have the greying, glaring, flattening, etching or drying of transistors, nor the bloat and overhang of tubes when tubes are used for small signal amplification.”
Carl Frederikson, Allnic Customer
