PRELUDE Hybrid Tube Preamplifier with the famous Western Electric 396a Tube

Debut 2016


  • Base on just one 396a tube (also takes 5670 and 2C51 ...etc)

  • 4X of Gain (We prefer to have fewer gain than higher distortion), 2V Output at Nominal, 0.1% THD-X

  • Perfect for low powered and triode tube amplifiers and high efficient speaker system that does not need a lot of gain and drive,  In return of the most organic/analog/quality music play back - less gain/less parts/less tubes ; LESS phase shift and signal changes too!

  • Tube regulated, by the powerful 12BH7, or the 12Au7 * the more powerful 12BH7 will last longer in the pose*

  • Tube rectified, by a small peanut type 6Z4 rectifier tube, which is a 7 pin miniature tube that is affordable and reliable

  • The power supply uses AC coupling (and is quiet enough to score a better than 90 db S/N Ratio, which was tested with an older Western Electric 396a), which to us is more superior in musicality than the absolute quieter DC coupling. Other than a good power supply design, along with our quality Canadian made power transformer that is made and tested to the highest electrical safety standards. An input filtering choke is in place, this is why even we heat it with AC, it is still quiet enough.

  • This is a true high end preamplifier regardless price, both sound, performance and functions. A pair of high quality transistors (thus called a hybrid preamplifier) are used for impedance conversion for driving all kinds of power amplifiers (including high power tube amps, solid state amps, or even sub-woofer amps!), which we combined together along with the goodness of tubes at the voltage amplifying stage.  We are able to get the advantage of each technology - both Sound and Performance, here, both the performance/specifications/measurements of solid state, and the charm/sound/bliss of the tubes.

  • Look so simple? perhaps the hardest to perfection. We like clean desk policy, while some others might make it looks busy to impressive..

  • High quality parts thru out, including CMC USA Gold Plate RCAs (3 Pairs of Input), and one pair of output , Mundorf coupling caps, Alps Japan Blue Volt Pot, Premium Selector, high grade 1% Japanese resistors and E-caps and solid signal path wires...etc.

  • Pricing : Regardless price,  the quality and sound reproduction satisfactions will be something in its own league! This design will be a success for decades ; like the Lp12!

  • Tubes being supplied are NOS USA 5670, NOS Sino 6Z4, and USA/Russian 12BH7

NEW Starting 2017 +

Since its debut, we thousands of hours of listening and comparison,

The new Mundorf EVO SUPERME SILVER GOLD Coupling Caps will be used on every new PRELUDE built.

PHONO STAGE will be standard on every new 2017+ built PRELUDE. Using our high end solid state phono stage used on the Triode Lab Au Pre / up coming Au Pre Mini, you are about to experience some best and quiet vinyls playtime, be it MM or high output MC cartridge. With the phono stage on board, it will also required more critical power supply and grounding network designs, as the phono stage requires a higher level of quality power supplies and regulations for the most quietest possible operations. The power transformer is also upgraded to the higher grade Hammond 300 series with covers, and universal voltages is available.  Phono Gain : 35.6 db / 60x, conservatively rated.

MSRP $2,999 CAD/USD/EURO,  well equipped with no options.

Finish : Finale's Tuxedo Black (Black Chassis's and Acrylic Face-plate)

Accessory : The "Gold Podium", a plinth/platform made with a thick 3/8" solid aluminum plate, which adds weight and stability, as well better resonance/damping control characteristic thru using hi-fi quality footers, and high quality rubber isolations between the plinth and the chassis. $500.00 CAD

Options : Dual Outputs $150 / Bypass selector with one set of Cardas Rhodium RCA Input $0 / DACT Selector Switch - $250 / Power Transformer Shield $100

Standard parts and bits : CMC Gold RCAs, 1877 Phono Gold Ground Post, Alps Blue Vol Pot, Lorlin UK Selector Switch, Furutech Gold IEC, Canadian made power transformer with world voltage, and Canadian made choke transformer ... etc.
