With the inclusion the new tube cage, the transformer cover was raised 2" to allow the cage to fully protect any KT-120/KT-150 tube. The resulting metal work and power supply changes have yielded our quietest Nautilus yet. Many still love the sleek lower profile look of the Classic Nautilus and as such we allow you to order your Nautiluswith the original metal work style or the Rev 2. The Classic Nautilus will additionally save you $1000 on the purchase.
The Story of the Nautilus is born of the same process that brought the Zions. We set out to build my private amps apart from ampsandsound. These were to be mine without branding and never to leave for demos. All too often, my own listening space was sacrificed for the need for demo stock. I chose the HK Cit II as my inspiration point. From that seed came my own Cit II Monos build on turrets just like the best amps of the golden age.
The Nautilus brings the dual-mono layout onto a single chassis. We started with our most versatile circuit, the Mogwai, and went about creating two separate amps that share a single chassis. 2 Power Transformers, Separate Power Supplies, Chokes, and input transformers. The amps are built with separate turret boards, with the shared component being the input tube, volume control, and outputs.
The Nautilus is a classic and decidedly prosaic design, as it employs turrets and point-to-point wiring & there is no silicone, ICs, or regulators. We consider this a standard-bearer of purest audio with an American sensibility. The Nautilus is built in a way few modern amplifiers are. This is not due to intrinsic inferiority, but rather it is impossible to rush and is incredibly expensive to produce.
The Nautilus has been described as a tube integrated amp for personal audio users. We mean by this, the Nautilus allows for five separate impedances to be selected for system matching and has a pair of 8ohm 5 way binding posts. The speaker vs. headphone output is selected with a small toggle switch on the back of the amp.

Product Strengths
- Five individualized outputs with different impedances
- Custom wound ultra-high quality output transformers provide excellent frequency extension and a flat response
- Engaging audio components offer superior sound quality using proven theories, solid engineering, and quality manufacturing, all taking place in the USA
- Brings out the very best qualities in all of the headphones tested, providing the best presentation ever heard from the Aeolus
- Build quality is a step-up from other amplifiers
Product Considerations
- The most expensive quarter inch plugs you can get, have locks on them, which can be annoying
- Unplug headphones before switching to speaker outputs
- Weighs around 68 pounds and around 93 pounds shipped in its large pelican style case—it is heavy
- Can clip when used with speakers if pushed too hard
Comparisons (according to reviewers)
- Nautilus sounds better than the ZMF Pendant Headphone Tube Amplifier and the Mogwai OG Tube Amplifier in every regard
- Nautilus is even more comprehensive and expressive through the powerful, well-controlled, tonal density that is detailed and rich in nuance—it has more extension and top-notch resolution
Takeaway: The Nautilus seems to be a versatile amplifier that brings out the best in headphones and speakers. It's built with quality parts and offers a lush and detailed sound experience for audiophiles who want to enjoy music to the fullest.

Our take on the brand
In the world of audiophiles, there is purist group militating for simplicity in tube amplification systems focusing on the use of the tube designed in the early days of tube technology: the directly heated triodes of which the most famous is the 300B. I300 is built around a simple 300B push-pull without feedback which offers unequalled musiciality of this tube.
After the preamplification using an ECC82, the signal feeds a phase inverter (called Schmitt) followed by 6SN7 triodes sufficient to drive the 300B.
The power supply is another strong point. In addition to the fact that each stage has its own power supply, particular care has been taken with the 300Bs themselves.
As direct heated triodes, the heater is the cathode. This requires a very "clean" power supply with no less than seven separate power circuits.
As for all our devices, transformers are designed and manufactured in our workshop. The one dedicated to the power supply, uses a magnetic circuit EI M6X of a design which gives a very stable operation, without noise and with a reduced overheating.
The output ones use a double CV38 magnetic circuit built according to our standards. The I300 is the only integrated with such an output transformer.
A design mode that allows the device to appear much more powerful than its 10W may suggest!
As far as design is concerned, the I300 remains faithful to our range and has a compact design. The 2mm thick 304L chassis easily supports the weight of the other elements. For a better comfort of use it is equipped with a remote control.
Listening to the I300, it's all about accuracy, subtlety and musicality of the 300B which magnify your tracks. No doubt it will delight demanding audiophiles triode lover!
Product Strengths
- Wonderful mid-band presentation that comes from the 300B tubes
- Bass is extended and controlled
- Provides detail and insight into recordings without being piercing
- Soundstaging is wide, deep, and natural sounding
- Every stage in the amplifier has its own power supply, and particular care has been taken with the 300Bs themselves
Product Considerations
- The included remote is functional, but not in keeping with the quality of the amplifier itself
- It is very heavy, weighing 40kg
- The high polished chrome and gold accents may divide opinion
- Those looking for an amplifier that is absolutely neutral in its presentation may want to listen to something else
Comparisons (according to reviewers)
- Vs Merrill Thor amps, the Jadis I300, to the reviewer's ears, is a far superior amp for listening and putting a big grin on your face
Takeaway: The Jadis i300 is built superbly and delivers a balanced sound with detail and emotional connection, making it a joy to listen to. It is a refined performer across the audio spectrum and with all kinds of music.
