Audia FL Phono - Phono Stage

 

Stereophile Class A

"... 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.

 

Nor did the Phono's dynamic presentation leave anything to be desired. It beat the Manley Labs Steelhead by a considerable margin, and possibly the Einstein as well, though that was too close to call."

 

" The Flight's overall presentation was free of grain and edge, and as pure and smooth as I've heard from any other great phono preamp. Its bottom end was taut, extended, extremely well defined, and rhythmically proficient. The top end was clean, ultrafast without being bright or edgy, and transients were detailed without sounding clinical. In short, I was reminded not only of the far more expensive Boulder 2008, but also of the pricier Naim Superline with Supercap power supply. "

 

"With its good looks, convenient front-panel controls (including Mono and +10dB on demand), and high-tech and equally high build quality, the Audia Flight Phono is a superbly made product that produces superb sound. I could live happily ever after with this pleasant surprise from Italy."

The Audia FL Phono preamp (phono stage) is definitely one of the most flexible high-end phono stages in the world, able to handle most cartridge specifications and yet delivers superb analog sound rivaling or surpassing the best in the market. Check out the information below, it is a wonderful set of of features.

The Audia Flight FL Phono preamp (phono stage) took 2 years to develop.

 

A separate power supply, the dedicated input preamplifier boards, standard and high gain (74dB maximum selection), and low noise are only few of its characteristics. Of course the separate power supply was chosen to improve the shield of the preamp and to reduce to zero the vibrations and resonance from the transformers.

 

Power Supply

A very well made power supply is required for top performance. On our phono preamp the power supplier is separate from the preamp chassis. A 50VA toroidal transformer supplies the analog stages. On it is placed the first power supply (+/- 38V). Inside the separate power supply there is a 15VA toroidal transformer too, to supply the relays and logic control.

 

A memory chip stores all the selections made. To receive commands from the pushbutton of the preamp chassis without electrical connections, several opto-isolators are used.

Preamp

 

The Audia Phono preamp is based on our current feedback philosophy; MM and MC cartridges have different electrical characteristics, and for optimal performance, there are individual input preamp boards on the FL Phono for MM and MC (i.e. 2 separate input preamp boards). MC and MC configurations can also be requested instead of the MM and MC standard.

 

The MC input preamp board has a 64dB gain. It is a transistor input preamp, with ultra low noise and very low offset output. A button on the front panel can be pressed to add +10 db gain, to attain 74db, extremely important for very low-output MC cartridges.

 

The MM input preamp board has a 40dB gain. It is a differential transistor input stage, with very low noise and very low offset output.

 

On both input boards, the impedance selector is very close to the input stage and selection is made with professional-grade gold jumpers.

 

After the first gain stage, there is the input selector, made with gold contact relays. Following the signal, there is the RIAA filter, made in passive configuration. The RIAA filter is made with 1% polypropylene and polystyrene capacitors. At this point, it is possible to select a subsonic IEC filter too.

 

The second gain output stage is made with out last release of current feedback. The module, called MCF NG1, completed redesigned, has the noise improved, as well as improved speed.

 

On the second gain stage it is possible to change the gain, from 24dB to 34 dB.

 

The second gain stage has an XLR balanced output too.

A mono selector can be an important element in achieving the best sound, playing a mono record and using a stereo cartridge on the turntable.

 

The mono selector sums the left and right channels together in the same manner as a mono cartridge would and will provide much better sonic performance.

 

On the preamp chassis, there is a low noise mosfet power supply (+/-28V) for and another power supply (+/-15V); in total, there are six power suppliers.


On the preamp board there is offset protection; in case there is a DC offset voltage on the output, the unit will go into protection, saving the unit and all units connected on it.

 

It is possible to order the Audia Phono preamp with the input gain board desired (MM and MC, or two MM inputs, or two MC inputs).

 

Moreover, It is possible to change the input gain board of the second input a second time.
