![]() Its the most versatile in that you can swap out the tubes and shift the sound palette without losing the speed and tonality. "Stellaris is my preferred amp for clarity & definition, speed, features, and general 'hi-res' listening. ![]() DNA has a 'house sound' (I suppose) and the Stellaris is right in line with what Stratus owners have grown to love." You hear the term 'house sound' thrown around a lot. The fingerprint of the Stratus is still there. What hasn't changed over the Stratus? The over tonality and texture. The low end is tighter and more solid sounding on the Stellaris. Separation is better and the sound stage seems more deliverate in that the images are more focused and less diffused. There is a large increase in detail over the Stratus. With the Utopia's I can turn the volume to max and I hear absolutely nothing. This gives the amp more 'speed' over the Stratus. "The Stellaris, over the Stratus offers much better dynamics, both large (macro) and small (micro). "As a current Stratus owner who loves that amp with the 800s, all I can say is that the Stellaris takes the 800s's to a whole nother level!!!" Mains voltage: 100/110/120/220/230/240V factory configurableĭNA Stellaris headphone amplifiers are proudly made in California from the finest components available. Balanced choke-filtered 2A3 filament supplies provide a deep black background and outstanding layeringĭimensions: 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.Audio signal tubes are DC heated and 2A3 tubes include nulling pots for the quietest noise floor.1/4" stereo TRS outut on -6dB gain attenuation setting has selectable output impedance between 3 ohm (Low setting) and 115 ohm (IEC setting).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 output has selectable gain attenuation between 0dB and -6dB for greater volume control range on higher sensitivity headphones.XLR outputs have 8 ohm output impedance.XLR outputs are selectable between unbalanced (single ended) and balanced headphone drive.I labeled it "K1000" in honor of the legendary headphone which was the inspiration for developing the Stratus. 4-pin XLR output can be used with all headphones - not just the K1000 only.All XLR and 1/4" TRS outputs provide the same power: 1.8W into 50 ohms, 900mW into 100 ohms.Dual 3-pin & 4-pin XLR and 1/4" stereo TRS outputs.Quasi-dual mono power supply with separate filter chokes and capacitors for left and right channels.Point-to-point hand wired audio circuitry using carefully selected audiophile components.They do not require feedback to attain low distortion. Triodes are naturally low distortion when operated into a high impedance load such as a transformer with proper specifications. ![]() Zero feedback or other error correction trickery. ![]() Flat and extended frequency response with very low distortion.Output transformers custom made to DNA's specifications in England by Audio Note UK.Purist class A single ended triode design.The balanced inputs are accommodated through custom Audio Note UK balanced input transformers - the best available. 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.ġ pair balanced XLR and 1 pair unbalanced RCA inputs. The result: Greater clarity, resolution, layering, dynamics, punch, slam, and authority. Every component is painstakenly selected by ear for the ultimate in sound quality and synergy working together. The Stellaris features bespoke Audio Note UK output transformers and Duelund CAST capacitors, both regarded as the best in the world, for an unparalleled listening experience. What began as an idea in July 2009 is finally a dream come true: Introducing the Stellaris 2A3 vacuum tube headphone amplifier. DNA Stellaris vacuum tube headphone amplifier
