SOLD Grant Fidelity TubeDAC-11 including NOS stock tube & Amperex 6922 made in USA gold pins tube. Original owner, used in smoke free, pet free environment. Very good condition, modest use. A real swiss army knife device: DAC (24/96 USB & 24/192 Coax/SPDIF), preamp, headphone amp, tube/ solid state outputs, 5 inputs: 2 RCA, 1 coaxial, 1 optical & 1 USB. Uses one (1) tube: 6N11, 6922, E88CC, 6DJ8, 6H23n and CCa, passive volume control. Comes with original box, 2 tubes mentioned above, power cord, cables: USB, coax, optical, allen wrench for internal tube access. Replaced cheap plastic feet with (4) Bright Star IsoNode feet (large):
http://www.audioadvisor.com/prodinfo.asp?number=BSISO&variation=L4 I’ve upgraded to a Gustard X-20 DAC for more than twice the price, otherwise the TD-11 would stay in my main rig.
Additional tubes that can be used in the TD-11 are listed in this separate ad & can be included at a discounted price (send PM to discuss):

From Grant Fidelity website:
• (5) sets of selectable inputs to allow you plenty of choices - including 2 sets RCA, 1 coaxial, 1 optical and 1 USB
• (2) sets of RCA Outputs tailored to your taste - one with transistor and one with a single DAC direct output - by pass tube buffer stage and volume control for you to match the DAC with other high end amplification (amp must have its own volume control as DAC direct output pass signal at full volume)
• Built-in transistor headphone amp to allow you to enjoy music in privacy (standard 6.5mm jack). Alternatively, you can use a RCA to 6.5mm jack adapter to connect headphones directly to the rear tube output. Note: front solid state headphone out can accept headphone with impedance as low as 16ohm; rear tube out only work properly with headphones with impedance over 300 ohm.
• Key parts are of audiophile quality throughout
• High efficiency low noise custom toroidal transformer which is usually only used on high end audio
• Separate power supply to tube circuitry to reduce interference
• Gold coated signal connectors throughout
• No over-sampling - input signal pass through at original sampling rate
• TE7022 USB 2.0 decoding chip is used to process data at 24/96kHz
• High quality Cirrus Logic CS4398 for main D/A converter - provide rich mid-range and low clock jitter
• ADA4075-2 as opamp for sweet midrange
