"A superbly made product that produces superb sound" - Michael Fremer, Stereophile

Stereophile Class A Recommended Component
 

  • Current model - rrp  $7990
  • The manual, alternative impedance cards and extra high quality resistors are included.
  • Use the preselected impedance jumpers or make your own custom jumpers with supplied cards and resistors.

 

Review:
"The Audia Flight Phono combined pitch-black backgrounds and world-class dynamic presentation with a clean, ultrafast top end and a taut, well-extended bottom end." Stereophile Class A Recommended Component

"...nothing but sonic pleasure... the Flight Phono produced music out of what subjectively sounded like an even blacker backdrop, and probably partly because of that, its soundstage presentation was among the most transparent, deep, and three-dimensional I've heard from any phono stage."
MF - Stereophile

A separate power supply, dedicated input preamplifier boards, high gain (74dB maximum) and low noise are only a few of its characteristics.


The separate power supply was chosen to improve the shield of the preamp and to reduce the vibrations and resonance from the transformers to zero.

 

Power supply
The Audia Flight Phono Preamp's power supply is separate from the preamp chassis. A 50VA toroidal transformer supplies the analogue stages. On it is placed the first power supply (+/- 38V).
Inside the separate power supply there is a 15VA toroidal transformer as well, to supply the relays and logic control. Previous user selections are stored in memory. To receive the commands from the pushbutton of the preamp chassis without electrical connections, several opto-isolators are used.

There is also a low noise MOSFET power supply (+/-28V) on the preamp chassis for the second gain stage and another power supply for the first gain stage (+/- 15V). Thus, there are six power supplies in total!

 

Preamp
The Audia Flight Phono Preamp is based on Audia Flight's current feedback philosophy. The MC and MM input preamp boards are different, because MC and MM cartridges have different electrical characteristics. The MC preamp board is a transistor input preamp with 64 dB of gain. The MM preamp board is a differential transistor input stage with 40dB of gain. Both have low noise and low offset output. On both input boards, the impedance selectors are close to the input stage and are made by professional gold jumpers. Custom resistors can also be used for precise cartridge matching from the rear panel.

After the first gain stage is the input selector, which is made with gold contact relays. Following this is the RIAA filter in passive configuration. It is made with 1% polypropylene and polystyrene capacitors. In this position, it's possible to select a subsonic IEC filter as well.

The second gain output stage, which is completely redesigned, has improved speed and signal-to-noise (S/N) ratio. The second gain stage is switchable from 24 dB to 34 dB and has a balanced XLR output.

A mono selector is an important element in achieving the best sound while using a stereo cartridge to play a mono record. The Audia Flight Preamp's mono selector sums the left and right channels together in the same manner as a mono cartridge would, which provides improved sonic performance.

The Preamp board features DC offset protection; if there is an offset voltage, this feature will protect the unit and all others connected to it.

Suburb or Town: Buderim State: QLD Payment Method: PayPal as a Friend Reason for selling: Buying a Scotty Cameron Newport 2.5 Further information: The Scotty Cameron Fastback with 2 x 20gram weights was released onto the US Tour in 2008. One of this design went to the Scotty Cameron Custom Shop in California and was called "Americana" when it emerged. Typically the putter is decked out in Red, White and Blue colours. The putter is 34 inches long and Right Handed. The only non-original addition is the Scoytty Cameron Grey Pistol Grip I added recently; the original had the Black and Red Pistolini grip. The putter comes with an Original Custom Shop Grip (unused) and another Scotty grip used when playing. The putter is in great shape ...no rust (WD40) and some paint wear on the sole of the club. A Scotty Cameron Oil Cloth and a Club Cameron Divot Tool are included. Please contact me for other information.
