Know before you buy
Because this amplifier produces 1.6 watts of power, it is specifically designed for high-efficiency speakers with a sensitivity rating of 96dB or higher. It will struggle to drive standard low-sensitivity bookshelf or floorstanding speakers.
By eliminating negative feedback, the amplifier avoids the phase shifts and timing errors often introduced by correction circuits. This results in a more natural, organic sound reproduction that feels closer to a live performance.
Separate power transformers prevent electrical interference between the power supply stages. This isolation helps maintain signal purity and reduces noise, ensuring a cleaner, more detailed output.
Yes, provided your speakers are highly efficient. While the wattage is low, the Swissonor 45 SE is capable of filling larger spaces with ease when paired with the right high-sensitivity horn or full-range speakers.
The unit utilizes 12AT7/6201 triodes for the preamp-driver stage and Full Music 45/n Mesh Plate triodes for the power amplifier stage. These premium components were selected to ensure the highest level of sonic transparency.
A shorter signal path minimizes the amount of wire and circuitry the audio signal must travel through. This reduces the risk of signal degradation and interference, resulting in a more accurate and transparent sound.
