Model no: QA-112-SP

Using the most common 6SL7 tubes in the amplification section, this pre-amp is built with a 6X5 tube rectifier which gives you the best medium size tube sound with a low price. The sound is very liquid, dynamic, rich, airy and warm with high definition. This is an semi hand-wired state-of-the-art pre-amplifier build for budget requirements. .

This SP version equipped with MC and MM phono stage, separate MC(200ohm) and MM(47Kohm) inputs, very suitable for user like both CD and LP as signal source. It also feature XLR and RCA outputs for XLR power amplifier connection.

This pre-amp can use more than 10 different models of tubes to fine-tune the tonal quality as well as dynamics and richness, with additional tube expansion adapters, even can use 6L6, 6K6, 6G6, 6V6, 6F6, 6Y6,KT66,6550, EL34, 5881, KT88, KT99, KT100...etc

The 6X5 tube rectifier can further upgrade by our super rectifier STR-104, direct plug and play without any mod required.

With this super rectifier adaptor, you can use 300B, 2A3 , 45 , 50 , 80, 83, 1616 , 3B28 or 866A as rectifier tubes option.

(Note: The price quoted is a special deal for newly order unit only, modification of existing unit will be around $300 higher than the following prices due to more works for disassemble of the original circuits)

Level 1 upgrade : (+ C$200)

Special designed "Super-Drive" circuit, output impedance lowered to 200ohm (can drive any power amp inputs from 600ohm up to infinity) with better bass control and punch , better definition and improved in overall tonal quality. By adding this upgrade, it sounds like the output with 10 pieces of power tubes being installed . With this level of upgrade, just add another $50 and you can have a headphone output with enough power and current to drive your headphone directly.

Additonal up-grade options:

solid-oak chassis add C$150

(optional chassis : Mirror steel, solid-oak, black piano )
