Through +90 dB sensitive loudspeaker, the Overture run very quietly, surprisingly quietly in fact, no noise whatsoever, not even from a short distance. a matched pair), and the other input tube is General Electric 6072. The 12BH7s at the input are R.A.M.-labeled (ie. The output tubes in the review unit came from Russia: Electro-Harmonix. Unlike in some other ANJ amplifiers, the speaker terminals accept banana plugs. Four single-ended inputs decorate the rear panel as do speaker outs for 4 and 8 ohm loads. All in all, Overture is a heavy and broad-shouldered amplifier to which the stripped front panel adds certain lightness and elegance. The caps are hand-made using ANJ’s own treated silver, and so is internal wiring.

The global feedback is just 3 dB, partly explaining the high transparency and coherence obtained.”īy the same token, the fact that the signal path features capacitors is not as important as where exactly the caps go in the driver and output stage. With especially carefully adjusted circuits, in addition to high quality parts used, only minimum level of feedbacks is needed. It prevents the music signal from passing through the biasing circuitry. “Using ultra-linear circuit is fine, but honestly, more important to the Overture’s sound quality is our fine tunings, Kondo’s original parts as well as some new design features such as the Constant Current Biasing techniques. “Using ultra-linear circuit is fine, but honestly, more important to the Overture’s sound quality is our fine tunings, and Kondo’s original parts.” thanks to intermediate screed grid taps built into the primary of the OPT, part of the load is common to the screen grid and the plate). The 32W+32W output stage of the Overture is ultra-linear connected (ie. It was at that point we knew that we had reached our goal.” Once we told them that they were listening to an E元4 Push-Pull circuitry, they were amazed about the quality level that can be retrieved from a pair of E元4. They thought that the circuit must be either Triode or Single-Ended design. At CES visitors praised the sound of the Overture as silky smooth, elegant yet with very clean and good dynamics. Masaki Ashizawa: “That’s what’s audiophiles keep constantly asking. Instead it’s a common Class AB push-pull design with fairly common EL-34s power pentodes that Mullard introduced in 1955. Overture ain’t a cool Class A single-ended amplifier with a fancy triode at the end. This is at least as significant a feature than the wire material.” But don’t worry, winding skills is another very important factor in making transformers, and all transformers in Overture are skillfully hand-made by ANJ. Therefore we did not apply any annealing to the copper used at the Overture transformers. Applying annealing will oxidize it easily, which eventually lowers its purity. Copper, on the other hand, delivers its best audio performance in its high purity form. Simply put, using “age annealing” means to find the best balance point when applied to silver cables. This generates a lot of problems for the cable manufacturing process resulting in a lower audio performance. “First of all, silver is a relatively soft material, which will “self anneal” with time, and too much additional annealing makes it “over” soft. Here’s what Audio Note Japan’s Masaki Ashizawa told me: But don’t worry, winding skills is another very important factor in making transformers, at least as significant a feature than the wire material.” “We did not apply any annealing to the copper used at the Overture transformers. Overture ain’t Ongaku though, that famous Audio Note Japan’s 211 (VT-4C) SET amp from 1988, with its mythical “silver sound” resulting from the patinated silver that has been used in the power transformers, wiring, components, and more and that it ain’t can be seen of its material basis. The chassis of Overture is made of aluminum instead of copper, and the OPTs are pure copper, not age annealed silver. More of that later.ĭespite its price, 30 000 euros, the Overture is the cheapest what Audio Note Japan can offer to its friends. That’s not my normal way of reacting to music but the sound was somehow so natural that I was tempted to. The reason I’m telling this is that hand waiving was the first thing that popped into my mind while listening to Audio Note Japan’s Kondo Overture integrated amplifier. I don’t know exactly what’s behind the behavior, but my guess is that it’s their way of internalizing music. Have you ever noticed how some Japanese audiophiles have the habit of closing their eyes and waving their hand along with the music as if they were conducting the orchestra by themselves.
