Ayon Audio Spark III

[Originalbeschreibung der Herstellers]

The Spark II is a substantial advancement of our already highly regarded Spark model. It is our “superb value” single-ended triode integrated vacuum tube amplifier for real music lovers. Low distortion, outstanding dynamics, holographic soundstage, detailed, fast and precise low frequency performance.

We completely revised the driver gain stage with the same 6H30 tube as we are using in our bigger amplifiers. The advantage is more transparent and livelier reproduction of musical performance.
