Being the first person to use silver wire in audio designs, Mr. Kondo was given the nicknames of “The Audio Silversmith” and “The Master of Best Audio” for his position in the audio industry.
To get “the highest sound quality”, Mr. Kondo did comprehensive research from the input position of audio signal up to the output of sound, without compromise.
The charm of silver wire was brought up by his hands.  The sound of silver is warm yet vivid; it can fully express the vitality of music.
With the bold but prudent idea to get the highest sound quality by using silver, an expensive metal which had never been used in audio before, the sound character of Kondo Audio Note then was created. Audio Note silver wire is a product of audio passion with careful attention paid to the handling of material. The products that Audio Note delivers produce sound quality that reaches beyond the highest worldwide standards.
The products of Audio Note are made for, and bond with, the audiophile’s heart.

Fully unleashed the wildness and dynamic of music while having all micro details expressed with textures.
Audio Note’s philosophy of an ideal integrated amplifier. A simple audio system of excellent balance. Capable of giving the best from details, dynamic and musicality.
Overture II Integrated Amplifier technical specs
  • Rated Power 32W + 32W @1kHz, 1% THD
  • Input / Impedance 4pairs (RCA, unbalanced) / 50kΩ
  • Output4Ω, 8Ω
  • Vacuum tube EL34 x4, 12BH7 x2, 6072 x2
  • FeaturesNew output transformer was designed for higher sound quality. By introducing a 3rd winding exclusively for NFB and re-calculated feedback amount, a well balance of dynamic and low distortion is realized.Power tubes are famous pentode EL34, which are first application in Audio Note product. In order to secure a minimum of 30W even matching with low efficiency speakers. Output impedance are 4Ω and 8Ω selectable.Reference to many classic push pull circuits with addition to our original new ideas, the performance of EL34 amplifier is elevated to a completely new level, combining both dynamic and delicate tonal balance.
SFz Step-up transformer

Based on our silver wire application know-how compiled over years, Kondo applied all of their transformer winding skills and understanding of wire diameter versus sound characteristics. The new SFz is a result of full exploit of the excellent sound characteristic of pure (99.99%) silver.
Complete freshness which awakes the delicate power of music expression over a quiet space.
It is the ultimate pleasure for any analog lover.
