model S505 "Flügel II"
Power Amplifier with Volume Control
With an analog power supply with a margin, a mechanical volume control, a high slew-rate amplifier by the fully discrete structure, we have developed back to the basics and newly designed pure analog power amplifier. For those who want a bit more power, this amplifier has 25 watt output. There is more precise expression power and dynamism, and it is characterized by full-bodied sound quality. Besides conventional voltage-mode type (S505v), current-mode type (S505i) can be selected. If you combine with an optional input selector (model S506 "switchgirl"), you can also switch the music source.
Smart Size ― Easy to wiring from rear panel.
With the player and your speakers, you can enjoy high fidelity music sounds.
Monotone Finish ― We strictly enforced basic performance.
The "Flügel" means concert grand-piano in German, all stainless steel finish.
Simple Front Panel ― Easy to operate.
Operation is the power switch and volume control only. If you combine with an optional input selector (model S506 "switchgirl"), you can also switch the music source. This power amplifier has enough gain to drive from CD player etc. without preamplifier.
No Habit Sound Quality ― Thoroughly eliminate the element that causes the stagnation of the music signal.
We deeply considered and serveyed about elements that cause a stagnation of the music signal. As a major factor, "bold and clumsy" connectors and terminals with too much conductor, metal plated wires, excessive amount of solder and so on. These by thoroughly eliminated, balanced of frequency range, there is no hysterical distorted voice with a feeling of a high-frequency range and electronic equipment smell incidental sound of habit, finished in a natural unprecedented "elegant" and "refined" sound quality.
Ultimate 25 watt ― Enough to enjoy music with full body sound.
Compared with small transistors, high power transistors tend to be unfocused and low resolution in sound character. By selecting high performance semiconductors, we developed this ultimate 25 watt amplifier. Incredible clear, sparkling and natural sound.
Sophisticated Internal Structure ― Fully discrete amplifier.
Amplifier section adopts a little configuration of simple amplifier stage as much as possible, was the highest priority on freshness of the sound more than anything. Sound quality with open and natural sounding and a sense of speed, you will forget the existence of the audio equipment.
Universal Speaker Terminals ― Banana plugs & various cables can be attached.
A speaker terminal compatible with banana plugs has been standard specification. This enables various speaker cables such as bare wire cords, Y-type (spade) terminals, C-type terminals, fine pins, and banana plugs.
