R2R Non oversampling tube DAC

Introducing the Tubadour VI – Audiomirror’s Latest DAC. The Tubadour VI represents a refined continuation of the visionary concept first introduced with its predecessors, the Tubadour III, IV and V. Built upon this legacy, Tubadour VI significantly elevates the listening experience to the highest possible levels.

This is the latest DAC from Tubadour series. It is also the best sounding R2R DAC compared to previous models. Has much better resolution, refined and clearer highs without giving you fatigue. Huge spacious soundstage with airy vocals, pinpointed musicians on the stage and deeper 3D feeling. Revealing details in music you’ve never heard before producing very musical and analog sound. A few customers who already got Tubadour VI say that they can not stop listening over and over their favorite tunes, discovering some music details, they never heard before was recorded in the same music tracks they used to listen. Tubadour VI is a triumph in the digital reproduction.

This Non-Oversampling DAC has similar approach as previous models Tubadour. It is built around Analog Devices’ finest, most musical and analog sounding chip, ensuring that you’ll enjoy unparalleled audio quality.

Key Features:

• All-format support: This DAC handles all formats with ease.SPDIF, Optical, AES, USB and I2S.
• featuring a completely new transformer design of tube IV conversion stage.
• DAC is supporting bit depths from 16 to 32 bits at rates up to 384kHz. PCM files are natively supported, while DSD playback can be achieved through “convert on the fly” options available in popular music player software such as Audirvana, Amarra, Foobar, Roon, and Euphony, all without compromising quality.
• Like previous models “no cap” philosophy, the Tubadour VI maintains same philosophy not using capacitors in the signal path. Instead, it employs Lundahl output transformers, widely recognized as some of the best in the industry. This design allows for both balanced and unbalanced outputs, delivering optimal performance. The result is a more natural, richer sound with enhanced resolution and tonality, free from artifacts and listener fatigue.
• Enhanced Tube Stage: The Tubadour VI uses same tubes as previous model, but in completely new design. Tube rectification, use either the 6Z4 or Russian 6Ц4П tubes. The tube gain stage is entirely new, different than Tubadour V and features two single triodes, 6S45P-E/6С45П-Е tubes. Biasing is different from previous model. Thus achieving a smooth, detailed, and musical sound with big soundstage dynamics and details .
• USB Re-clocker: A built-in USB re-clocker improves the precision, separation, focus, and texture of all USB-sourced signals. It effectively reduces jitter, ensuring exceptional audio quality.
• Highest possible quality components: The Tubadour VI incorporates Z-Foil “naked” Vishay resistors in both the IV section and tube stage. It also has a ultra low-noise power supply for the USB and I2S inputs. The IEC power inlet is a Furutech – Gold, guaranteeing robust and reliable power delivery.
• Two separate power transformers.
• Enhanced vibration Isolation: A standout feature is the inclusion of IsoAcoustics “GAIA” vibration-absorbing/isolation feet. These feet enhance the clarity and focus of the sound, providing an audio experience akin to replacing an interconnect cable with a high-end one.
• Connectivity Options: Silver RCA and XLR outputs allowing  both balanced and unbalanced connections.

After years of exploring various DAC technologies we still use AD1865N-K for it’s musicality, non digital and sterile analog sound.

Please note that a power cord is not included.

USER MANUAL

This is a non-oversampling, all format, vacuum tube DAC. It is based on Analog devices AD1865N-K flagship DAC chip. This is the best and most analog and musical sounding DAC chip ever made.

DAC uses two single triodes 6С45П/6С45П-Е Russian tubes for analog stage. Close equivalent, but different pinout is 417 tube, so don’t try to replace it with 417. 6С45П/6С45П-Е outperform any of the other popular 9pin tubes. Power supply uses 6Z4 or Russian 6Ц4П rectifier tube. DAC output is around 1.9/2.0V.

• DAC has a built in USB re-clocker. It reclocks all signals coming from a USB source. It improves a lot the resolution, tonality, balance, separation and dynamics. Lowers siginicantly the jitter. DAC has a build in slow ramping up high voltage (HT) supply to prevent  shortening the tubes life. Due to this the DAC will perform with full scale level and sound quality after approximately 10 min after it’s turned ON. Do not leave the DAC ON for long period of time (24 hrs. or so) if you are not listening to music. This will only shorten the tubes life. DAC has a built in delay when turned ON. Around 2 minutes. 15min or so for DAC warm up is quite enough. DAC parts has a break in time of between 100 -150hrs. The most noticeable improvement in sound will be in the first 20-25 hrs. Output transformers need around 150 hrs break in timeDAC does not have MQA capability. DSD files can be played if the player/streamer used – convert  DSD to PCM on the fly. Most players like Foobar, Audirvana, Amarra etc. can do this on the fly. DAC has two knobs on the front panel. Left one is POWER ON/OFF Right one is input selector. DAC has COAX(SPDIF) TOSSLINK(OPTICAL) AES, USB and I2S inputs, selectable from the front right switch.DAC has Blue LEDs on the front panel showing the selected source.The most left LED is a white color and it indicates when the DAC has locked into the source, applicable only for Coax, Optical and AES inputs. It does not work with USB and I2S. DAC outputs are Unbalanced RCA and Balanced XLR. They are switched by a small toggle switch  on the back. Both outputs XLR and CA can not be used at the same time.
