Our good old designs / legacy museum.

*** If there is something you liked on this page - we might able to still make you one =) Just we have to arrange for something better for shipping (as we usually no longer have those box/foam anymore). And some prices wouldn’t be same unfortunately - the labour alone is $2-3K already for example.

Model : EL84TT MKII (2017+)

2020 COVID19 - DISCONTINUED / Due to the extreme high cost of manufacturing cost here in Canada due to the pandemic, we no longer can produce a product below this price point as we don’t allow our quality shifts. We regret the decision no matter how much we love the design (go to our history page to get to know more the original idea!), we also spent many years of effort to make , evolve , voice it better than ever. Which goes head to head with the finest amps around the world, but in a PP form AND a non-triode power tube. The EL84TT Integrated Amp will always be an achievement at our lab. Thank you for those who support and shared the same enjoyment of its fine sound. From now our, us, like our name suggest, will only be focus with triode tubes and designs.

The EL84TT is an authentic, high-end integrated tube amplifier operating in Class A Push Pull Triode -- a pocket-sized reference unit, that's not afraid to challenge high-end triode pre/power tube amps combo. It features our S.E.A 2nd Gen Driver Design that sounds like a SET kind of amplifier, but with the control and bass of a conventional push pull amplifier.

It is used by tube connoisseurs and sound professionals as a point of reference and comparison.

MK2 : On our latest offering, we transform the original award-winning design to a mature and even better state, thanks to our R&D team and their ongoing effort to refine the sound and better hard-wares. After almost a decade of usage of the perfect transformers and parts, we are able to evolve it above the already best statues. Here are the further improvements over the "original" circuitry wise. On the hardware and sound tuning list above, it already scored the best sound/cost ratio.

1. An advanced regulating stage for power supply - heavily inflated our cost, but that's the only way to beat our previous dark quiet background and our infamous quiet operations, it also enhance the life of tubes expectancy

2. Improved power supply design and grounding network throughout the circuitry, seeing more ECAPS than previously? They are there for reasons! And they are all high grade, high temperature, high rating Japanese quality ECAPS

3. Better gain and boost than previously - more speakers will be easier driven and going louder

4. Like our original EL84TT prototype, there is only one set of input for the purest signal transfer - it goes directly to volume/pre-amp stage. The original idea of the EL84TT is to pursuit the best possible sound, instead of to fulfill the convenience of lazy audiophiles

5. Since we have used and know every piece of parts we will be using on the circuit, all the useless spots and parts will be obsoleted for cleanest channeling and lower the possibility in picking up noise.

6. New layout allows made as being integrated design, or a pure power amp (with less gain)

7. Reconfigured from standard Class A PP-Triode Mode to PP-Ultra Linear Mode for doubling the power to 10W Class A (Triode mode will be an option for triode sound die-hard fans - specific when ordering)

8. Further transformers upgrades are possible, even upgrade the spec to a 7189 tube amp with even more power!

"… a very balanced amplifier with a detailed transparent mid-range that never shouted, with a rich weighty bass, a lively non-flashy treble without any kind of aggression and above all a dynamic and saturated sound that spoke to the heart perhaps a little more than the brain which is how I ultimately like my music spiced."

6Moons by Frederic Beudot

 "A very linear unit with impressive focus plus deep and defined soundscape."

EL84TT since day one was perfect. And good enough to pass TUV’s electronic safety test:

Model: EL84TT - FFX

A true amp for the EL84/6BQ5/7189 fanatics!

Available to configure in Class A Push Pull Triode 7W, Pentode or Ultra Linear 15W+ Class A/B

Standard Part List : 15W Rated Hashimoto Potted Type Output Transformers (or the 30W Classic Sansui OPT made by Hashimoto), Cardas Binding Posts / RCA, Mundorf Silver in Oil, Furutech Rhodium IEC, High quality input wires, Soundcoats, QQQ Japan rectifier tube socket...etc

These are the finest wattage thanks to Hashimoto. They have the fewest power losses, the most quiet condition and ideal measurements in everything (these were measured better than almost over 100 db for the S/N ratio - which is VERY quiet), which makes a 15W"amp" drive like a 30W. Don't let the numbers fool you. The best tube amp will easily outpower your average quality tube amps so you can drive more different speakers PLUS, you always hear more. This is why most experienced tube-philes would only spend time with a tube amp mounted with decent transformers, because they know they are listening to everything out from their records/source.

Special Features:

• FFX Limited Edition Power Amp/Developed complete with full suit of exotic Hashimoto transformers   

• FFX Silent Ground Technology - Optimal grounding network design and parts layout, along with best power supplies materials for the best hum and noise control and best S/N ratio. And yes, it measured quieter than any power transformer we have used for EL84/6BQ5 type tubes, salute to Hashitmoto!

• FFX V-max Tunings - All FFX models are unleashed by us, with all its special advantage with its exotic grade parts and settings, which allow us to remap the entire circuitry for its maximum "Valves" output power and quality, both numbers and aural.  

• This is one of the quietest amp we have come across!  The power (read VERY conservative) and the quality is exceptional for its price, this is built for our loyal customers who have seen the potential of our EL84TT. Finished in Porsche Riveria Blue (or your preferred colour). All parts and materials tailored to customer.

 $5,999 USD + Options

Limited. Made to Orders Only. Lead time required.Pure copper chassis available for extra $2,000 USD.

EL84TT-FFX R

By using 7189a / EL84M tubes ONLY, with all newly-redesigned circuitry for this higher power output tube, which focus on strengthened/enhanced front-end design (an auto balance design is also used over trim pot), as well, an upgraded power supply handles the extra wattage output AND operating voltage. The FFX-R enables to yield a solid 20W Audobias in Pentode Class A/B or 8W in Triode Class A. The power supply is also regulated on the FFX R.

The FFX-R have the Hashimoto Output Transformers upgraded to 25W Potted or 30W Classic Type Sansui Output Transformers by Hashimoto (the one used on the EL84-TTS), also a bigger power transformer is used, as the operating point shifted up from under 280V to 300-330V. An extra pair of oil caps is needed at the front end, along with a few pairs of extra E-caps, which are crucial to the other 4 Silver in Oil coupling caps to make up this perfect topology - nothing less, to finish off as the best of its type around the world. And for those who really love this tube so much, ask us about the EL84-FFX RS that puts out a solid 27W+27W, with fixed bias, complete with our Canadian in-house transformers. $6,999 USD + Options

2A3 Push Pull Mono-Blocks

Where D.H.T. combines the beauty of power.

2019 : Our original 2A3GT Push Pull monos are pushing 10 years old, and aging more gracefully than we had ever imagined. However, we haven’t been sitting around sipping espresso lattés and admiring our handiwork this past decade! Instead we’ve been rethinking everything, as usual. How do we improve a design that already ranks among the best (Glad you asked)? Anyway, for the whole new Second Generation:

Model: 2A3GT-FFX (MK2)

HOMAGE-30 MC Phono Stage

• Solid state design - although we are the tube experts, but there are more advantages with solid state than tubes for the most quiet operation in this case, and few tubes qualify to the level we wish to shoot for - but they are rarely available as they are non common audio tubes.

• External power supply, with Canadian power transformer with world wide voltage.

• Tailor to your cartridge (And if you ever getting a new cart, just send the unit back to us to redial the perfect settings as well a complimentary check up, included up to 2 times for free if needed)

• Compact size , roughly 7" long x 3" tall and 4" wide, for the pair.

• We mastered turntables more than 30 years ago, many phono amp designs are made ever since (both for our own enjoyment and OEM), and back then we were fever enough fly all the way to Japan to beg old Mr.K-san for our own cartridge. Here, with the HOMAGE-30 MC Phono Stage, you are getting our finest design and philosophy accumulated in all these years. And this is our favourite MC design from 30 years ago and it just come back to life!

• This MC amp teams up perfectly with our Triode Lab's and Finale's pre-amplifiers onboard phono stage (the perfection phono foundation) or other high quality phono stage (if it is as quiet / and measure as good as our foundational phono stage on our preamps) - this is the foundation, and it has to be the best!

  MSRP : INQUIRE Within , deep discount for our return customers.

And if you want more power around with 2A3 tubes, we also have the 8 Watts 2A3 PSDM (Parallel Stereo Dual Mono) version for our 2A3 connoisseurs. And 4 Watts for the 45 PSDM.

2A3 / 45 Parallel Stereo Dual Mono

Reference Integrated Amplifier

DUO Feedback Technology , exclusive and debut on this 2A3 Parallel SE Design. Double the bandwidth, higher efficiency and stability, lower distortion and noise, and beautiful curves of both measurements and image of the body. (Unique feature / design on the PSDM amps only)

• Dual mono design, each channel's own output, power transformers and tube rectified power supply stage on to the same chassis - Total 5 pcs + Transformers.

• Feature using Mundorf power supply capacitors - Our design uses one big capacitor over multi-piece of E caps for better S/N ratio and fewer chances of interference. What's more, a long duration of R&D of the layout and location on each (out of 5 pcs + of transformers) is carefully measured and tested, to ensure each spot where the transformer is mounted is the quietest place to be. Even the horizontal/vertical placement of each transformer make a difference, if you notice how we handle the transformers on the chassis.

• Mundorf Supreme Silver in Oil Caps are voiced and used across the range (FFX or Canadian trim)

• Tubes same as 45/2A3i SET Integrated Except the PSDM has one more pair 45 / 2A3

• Class A 8 Watts (Conservatively under-rated), on our prototype, with One Electron USA Output Transformers, we were measured max power of 9.5Ws. The final outputs will depend on the make of transformers. Starting 2018, full suit of Canadian transformers or HASHIMOTO (Sansui) will be used. Class A 4 Watts for the 45 Triodes.

REVIEW:

| Having the first Triode Lab 2A3-PSE stereo amp was an honour, and using it was a joy. The amp consistently made me smile; it made me want to rifle through my records to find more music to play. I enjoyed every aspect of this amp, and I’d consider it a worthy addition to most any high-end domestic audio system. I was sad to see it leave – I don’t know when another component of this caliber might grace my room. Very highly recommended.|
