DNA Stellaris vacuum tube headphone amplifier

What began as an idea in July 2009 is finally becoming a dream come true: Introducing the Stellaris vacuum tube headphone amplifier. Building upon the musicality of the Stratus, the Stellaris features bespoke Audio Note UK output transformers (prototype shown without covers) and Duelund CAST capacitors, both regarded as the best in the world, for an unparalleled listening experience. Every component is painstakenly selected by ear for the ultimate in sound quality and synergy working together. The result: Greater clarity, resolution, layering, dynamics, punch, slam, and authority. Hear all of the subtle nuances of an instrument being played and inflections in a singer's voice which makes each performance and recording special.

The Stellaris will be offered in 2 versions:

2 pairs unbalanced RCA inputs

1 pair balanced XLR and 1 pair unbalanced RCA inputs. The balanced inputs will be accommodated through custom Audio Note UK balanced input transformers - the best available.

Design features include:

• Purist class A single ended triode design

• Output transformers custom made to DNA's specifications in England by Audio Note UK

• Flat and extended frequency response with very low distortion

• Zero feedback or other error correction trickery
Triodes are naturally low distortion when operated into a high impedance load such as a transformer with proper specifications. They do not require feedback to attain low distortion.

• Point-to-point hand wired audio circuitry using carefully selected audiophile components

• Quasi-dual mono power supply with separate filter chokes and capacitors for left and right channels

• Dual 3-pin & 4-pin XLR and 1/4" stereo TRS outputs

• All XLR and 1/4" TRS outputs provide the same power: 1.8W into 50 ohms, 900mW into 100 ohms

• 4-pin XLR output can be used with all headphones - not just the K1000 only. I labeled it "K1000" in honor of the legendary headphone which was the inspiration for developing the Stratus.

• XLR outputs are selectable between unbalanced (single ended) and balanced headphone drive

• XLR outputs have 8 ohm output impedance

• 1/4" stereo TRS output has selectable gain attenuation between 0dB and -6dB for greater volume control range on higher sensitivity headphones

• 1/4" stereo TRS output on full gain, 0dB attenuation setting has selectable output impedance between 8 ohm (Low setting) and 120 ohm (IEC setting)

• 1/4" stereo TRS outut on -6dB gain attenuation setting has selectable output impedance between 3 ohm (Low setting) and 115 ohm (IEC setting)

• Audio signal tubes are DC heated and 2A3 tubes include nulling pots for the quiestest noise floor

• Balanced choke-filtered 2A3 filament supplies provide a deep black background and outstanding layering

• Input selection via rear toggle switch

• TKD volume control potentiometer

• Tube complement:

6N1P input/driver tube
2A3 directly-heated power triodes
5U4G directly-heated rectifier tube

Input impedance: 50Kohms

Dimensions: 8.5 " H x 17" W x 14 " D (21.6cm H x 43.2cm W x 35.6cm D) including tubes and connectors & controls.

Mains voltage: 100/110/120/220/230/240V factory configurable

$6700 for unbalanced RCA inputs version
$8900 for balanced XLR and unbalanced RCA inputs version
