The Allnic H-5500 replaces the outgoing H1202 with a number of significant improvements.

Like all Allnic Audio products, the H5500 Phono PreAmp uses Permalloy (iron and nickel alloy) for its transformer cores. As per its predecessor and indeed the original H1200, it employs four NOS E180CC twin triode valves which is much favoured by Kang Su Park.

Like the Allnic 1202, this new preamp also uses a 7233 voltage regulator tube and a 5654 for voltage correction in a far superior tube power supply. A pure class A design with no negative feedback it offers 278Ω, 117Ω, 69Ω, and 29Ω loading settings, selectable from the chassis-mounted rotational pots, each of which is tied to a specific gain factor. A soft start function, a convenient mute switch, and single-ended input and output connectivity at the rear complete the specs.

The H5500 offers users dual MC and dual MC inputs so up to four cartridges can be accommodated at any one time. The fascia has also been adorned with Allnic’s famed power meter, normally reserved for more expensive products. The meter is very useful in indicating and quickly diagnosing tube replacement or failure.

The power transformer has been upgraded and the unit has also been furnished with the same step-up transformers from the H7000 and flagship H8000

Build quality and finish is also up to the usual very high standard we have come to expect from Mr. KS Park. Available in silver or black. 2 year warranty on all Allnic Audio Products, 1 year on factory-supplied tubes.

The Allnic H-5500 phono preamp offers:

• Dual MM and MC inputs
• Mu-metal shielding to increase SNR
• Power supply capacity double that of the H-1202
• Current meter for monitoring tube status
• Redesigned larger, heavier, and more solid aluminum chassis
