2A3RSR V2

With the upgraded Nordic Gold Copper finish.

Our 2A3RSR V2

This is our new take on our flagship parallel SET mono-blocks. With different sound presentation and character than the original 2A3 RSR (whom has absolute performance and control in mind when we designed it, adopted using newer quieter front end preamp tubes, which it will continue sell along together with this latest V2 because of it’s strong demand), using our favourite sounding front end / preamp tubes - the 6H30 and the 6SN7/CV181, that is arguable having better tube flavor and sweetness. Mechanical side we also make this a smaller in size, right for most hifi shelves.

8W Single Ended Class A Autobias
10W Maximum (1.74% THD+N). Yes, that is more powerful than a 300B or even 211

2A3M-II FFX Version available with full suit of HASHIMOTO : MSRP $16,999
This version uses the high output 2A3’s PSET Output Transformers (20W Core @ 1.2K Impedance, co-design and engineered between Triode Lab and HASHIMOTO) found on the 2A3MII RS FFX.

This is our entry parallel version , double the power, while maintaining the best voice of 2A3. A perfect amount of circuitry tuning, parts matching, and our lengthy aural testing make this perhaps the best sounding pair of 2A3 Parallel SET Mono Blocks on the market. The brilliance of the 2A3 highs and unique tone, power and control, bass and ease of setup are far easier...something you can use to drive a pair of little speakers, as big people have been looking for a subwoofer!

"The 2A3M-II mono blocks offer such depth of resolution and beautiful recreation of musical sources that they are in a class by themselves. I don’t know all the exact technical details with which Frank builds his equipment, but I do know their ability to generate a crystalline clear sound-stage that is holographic, while remaining lifelike, creating chills up and down my spine frequently. This phenomenon is extraordinary to experience when it occurs as a result of stereophonic reproduction. I hope that you have had a similar experience, so that you can place yourself in the seat in my room when it occurs and imagine what it is like to listen to these amps."

2A3M-II RS

The 2A3M-II RS bridge between the M2 and the RSR.

The RS, like its name suggested, it has a tie to the flagship RSR mono blocks.
Which shares the same front end RS design with the 12AX7 and with a 12BH7/ECC99. Its our best shot in 2A3 SET design.
The power supply remain the same as the 2A3M2 due to the compact size of 8” W x 17.5”L - we are using each inch of the chassis.
Hammonds Canada Complete Set of HIFI Transformers (Show above)
Rectify tube use: 5R4 tube perfectly. With 5U4, we were able to measured a max power of 11 Watts. But for best result, we recommend 5V4 / GZ32 / 5T4, or the 5R4. Matched brand please, or from the same batch/date. Any other type of rectifiers are not recommended, and warranty voided if used due to different voltages.
Shown above : finished in optional BMW M Valencia Orange-Red Metallic Paint
Starting $14,999 USD / Pair
FFX edition available for $18,999 USD / Pair (BELOW PICTURES), which features the Hashimoto x Triode Lab 20W Output Transformers (Design by Triode Lab / Engineered by Hashimoto) specific for the 2A3 Tube. As well powered by the Hashimoto 2A3 power transformer, and all the FFX circuit enhancements.

Is there an end? - ask for a stereo end game RSR version.
