- am·bro·sia \am-ˈbrō-zh(ē-)ə\ The food of the Greek and Roman gods, something extremely pleasing to taste or smell or, in this case, to hear. The Ambrosia 2000 Second Edition preamplifier is a brilliant example of what a reference, full-featured, stereo preamplifier can be. This fully-balanced system nucleus features giant power supplies, an optional MM/MC phono stage, headphone amplifier, tone and balance controls and an ingenious remote control. Some recent improvements include redesigned internals for improved stability, lower noise and a new home theater bypass function. There are no physical switches or controls of any kind in the signal path; the user interface is all electronic and galvanically isolated from the audio circuit. All functions are 100% microprocessor controlled and can be controlled from both the front panel as well as the remote control.
- At 50 pounds, the Ambrosia outweighs many power amplifiers! Most of the weight is due to the huge low-EMI power transformer. It features four secondary windings that power each circuit section independently, and in the process, eliminate ground loops. In addition, 15 independent power supply regulators are employed throughout for immunity against AC mains fluctuations. Every attention to detail and function contributes to the final, undeniable conclusion: The Ambrosia is a sonic tour-de-force befitting the finest audio systems. The Ambrosia is a sensation at any price point. Here is a full function preamplifier complete with MM and MC phono capability that for me bridges the sonic gap between solid-state and tube designs. - Dick Olsher, Enjoy The Music
- Four completely separate sets of transformer windings to power the four main preamp sections: moving coil, moving magnet, line, and display control. An additional 15 independent power supply regulators work in concert to eliminate ground loops and power supply noise. Optional phonostage: RIAA equalized, completely separate circuits for both MC and MM cartridge sources. Each circuit has its own set of direct outputs which bypass the internal switching and each has a dedicated user-selectable low cut filter. Highly configurable, sophisticated Menu system to tailor virtually every parameter of Ambrosia's robust feature set to your satisfaction. A total of nine pairs of inputs: Three main inputs (CD, TUN, AUX) Two tape loop inputs (Optional) phonostage inputs, one each for MM and MC One combination XLR jack that can be used balanced or unbalanced Home Theater Bypass input
- Outputs: Two pairs unbalanced and two pairs balanced. Two headphone output jacks on the front panel powered by a unique, balanced power buffer idling at 4.5 watts per channel, capable of driving virtually any pair of headphones. The top output is a "switched" output: while in use, the Ambrosia will mute the line output to the connected amplifier. Fully balanced design with a sophisticated circuit that generates almost no distortion. Moreover, all of the distortion by-products in the Ambrosia come only from the passive switches and volume control, which are virtually inaudible. Highly customizable bass and treble controls. 14 gauge robust powder coated steel chassis and anodized aluminum front panel. Large, easy-to-read front LED display. Optional custom, solid aluminum remote control allows for all of the functionality available on the front panel.
