FS: PRICE DROP! Firestone Audio Libby DAC/amp - Pure Class A headphone amp - 24bit/192kHz

Will Ship To: Anywhere

For sale is a new Firestone Audio Libby DAC/headphone amplifier. This is a great desktop amplifier that is cable of 24bit/96kHz input and 24bit/192kHz output via resampling.

I bought this as a combo package along with my DT880, but recently I've started using tube amplifiers, so I'm going to sell the Libby here. In my opinion it is an excellent amp, and can power the DT880 (600 ohm), DT990, K701, HD650, Philips Fidelio X1, SR325i, MS2i very well (these are the headphones that I demoed with at the store). It is also quiet enough for IEMs (E4c, ASG-1).

This is the second generation Libby that has better power transistors, and added cooling for better performance.

Asking $375 $300 $275 OBO (or best offer) - this DAC/amp usually retails for $500-600+

The Libby accepts the following inputs:
  • Coaxial
  • Optical (SPDIF)
  • USB
  • Line-in
  • AES-EBU

It has a unique design that take analog inputs and converts them to a digital signal, then is able to resample them up to 24bit/192kHz. For digital inputs it supports up to 24bit/96kHz streams.

The unit has very good components and specifications:
  • Amplifier Structure : High current / swing output amplifier, four step bias control
  • Power structure analog: High precision linear voltage regulator (Analog system)
  • Power structure digital: High efficiency / frequency voltage regulator (Digital system)
  • Power Mode : Stand by and Power on mode, provided with main power switch to shut down
  • Headphone impedance : 16ohm to 600ohm
  • Circuit Protect : Output short / system over current protect
  • Characteristic : Using OP275 and high current power transistor to build high quality headphone amplifier
  • Frequency Control : Adjustable from 44.1kHz to 192kHz (upsampling also for USB)
  • Bit Length Control : Adjustable 16-bit or 24-bit data length
  • Mute Control : Provided to directly mute headphones without rotating the volume knob
  • USB Support Format : 16-bit, 32 / 44.1kHz / 48kHz
  • SPDIF / AES-EBU Support Format : 24-bit, 96kHz (MAX)
  • Power Amp : TI - TAS5706
  • Processing Chip : TI – TAS5086
  • ADC Chip : TI – PCM1803A
  • USB Chip : TI – PCM2704
  • SRC Chip : TI – SRC4193
  • Receiver : TI - DIR9001
  • Housing dimensions : 208 x 220 x 55 mm (D x W x H). Housing only without parts 'sticking out' like switches, connector parts, etc.
