Marantz, a world leader in advanced home entertainment solutions, is celebrating 30 years of visionary guidance from its European Brand Director, legendary audio designer Ken Ishiwata.

The daylong event included a technical presentation by Rainer Finck, former Philips digital engineer and now Boston Acoustics European General Manager, and from Ken Ishiwata, Marantz's "Brand Ambassador" and unofficial keeper of the company's "audiophile flame," a detailed company history along with a backgrounder on his involvement in the finalizing of the NA-11S1's design.
Following lunch, attendees were treated to a listening session in Mr. Ishiwata's playground: an impressively large and well-treated sound room. The listening session reinforced the commonly held belief that he is among the most skilled set-up and demo hosts in the business.
Mr. Ishiwata said dealers, when surveyed, were adamant that video not be included. He said he was relieved because the noise problems produced by video circuitry are even more difficult to isolate than the ones associated with USB-even asynchronous USB- that the NA-11S1 incorporates.
The problem is that while transformer-coupled Ethernet connectivity is inherently isolated and noise-reducing, the USB standard includes a 5V power function that unless carefully isolated, can introduce high noise levels. In fact, Ishiwata was so unhappy with the proposed production sample's isolation scheme, he rejected it.
The fully balanced analog section features Marantz's HDAM-SA2 and HDAM modules, while capacitors and other components were chosen based upon extensive listening tests conducted by Mr. Ishiwata who pointed out that a series of copper topped capacitors that looked great were replaced by some nichicon silver topped ones that sounded better.
While the "future-proof" product launch was impressive both technologically and sonically, Ken Ishiwata's oral history of Marantz-made more compelling by his long association with the brand- was one of the trip's high points, especially his insight that, coincidentally or not, the company changed hands during technological upheavals.
Here's where the young Ken Ishiwata, then living in his native Japan, enters the picture. A friend's father played for him a Julie London record using a Marantz 7C (the "C" is for "wood case" not a different model) and instantly Mr. Ishiwata's life forever changes. He had never heard such sonic purity and such realistic sounding vocals.
The young man could hardly afford to buy a 7C but he copied the circuit and built his own. It didn't sound anything like the real 7C and thus he learned the hard way how various different components within a circuit can alter the sound! Experimenting with various brands of capacitors and other components, Mr. Ishiwata was eventually able to turn his version of the 7C into a reasonable facsimile of the real thing.
The 7T, a transistor version of the 7 was introduced, but according to Ishiwata, it didn't sound the same or even very good.
Another interesting factoid from Ishiwata was that the 16 bit system was not settled upon because of technological issues. In fact, higher bit depth was then easily attainable. The real reason for the 16 bit format was that it made easier downgrading the technology to produce less expensive equipment. Yet another reason for some of us to be infuriated by the CD!
Hopefully this "history lesson" courtesy Mr. Ishiwata gives younger audio fans the necessary background to appreciate the value of the brand name Marantz and to understand how despite the numerous ownership transfers, the brand has survived with its sonic legacy intact-which is more than can be said for some of the other storied audio brands created by post WW II electronics entrepreneurs.
Thanks in great part to Mr. Ishiwata's history lesson the two day trip to Eindoven (I was the only American audio writer invited) furthered my appreciation of Marantz products past, and created a benchmark by which I will evaluate future Marantz products.
K&W Audio - Latest News for Audiophiles, making the best music sound better in Calgary Alberta., 13 Mar 2012 [cached]
Marantz America, a world leader in premium home entertainment solutions, today announced that it is supporting the launch of its highly anticipated KI Pearl Hi-Fi components with an elegant hardcover coffee-table book ($39.99) and specially created dual-layer SACD ($59.99) which celebrate the 30th anniversary of its European Brand Director, legendary audio designer Ken Ishiwata.
The book and SACD can be purchased together in a special 30th anniversary boxed set ($94.99) or separately at select Marantz retailers. Like the upcoming KI Pearl units, including the SA-KI Pearl SACD Player ($2,999) and the PM-KI Pearl Integrated Amplifier ($3,599), the anniversary books SACD are available in limited quantities only. (A limited number of the SA-KI Pearl have already been released to Marantz retailers).
Both the book and CD offer unique insights into the life and work of Ken Ishiwata. Richly informative book not only spotlights Mr. Ishiwata's extraordinary career and many achievements, but celebrates Marantz's commitment to making "Music Matter," which is exemplified in the KI Pearl Products. The meticulously engineered SACD features the music of well-known singer Katelijne van Otterloo, chosen by Mr. Ishiwata as a fellow perfectionist who understands emotional involvement in music.
It contains12 classic jazz numbers such as 'Summertime', 'Misty' and 'Girl from Ipanema,' each exemplifying Mr. Ishiwata's passion for music and reflect his ongoing quest for audio perfection. To create strikingly realistic and richly detailed stereo imaging, the hybrid SACD combines the music of 100% acoustic instruments with a simple sound stage.
The two KI Pearl components combine art gallery-quality aesthetics with the highest quality build materials, copper-plated chassis and advanced audio performance features. Most importantly, they were designed and personally tuned by Mr. Ishiwata to reproduce music exactly as the original artist and recording engineers intended. The rock-solid SA-KI Pearl SACD Player, for example, was built to Mr. Ishiwata's demand for a "bulletproof" vibration-damped cabinet, massive power supply with a toroidal transformer and unsurpassed precision CD mechanism.

One of the keys to the enhanced performance and wide sonic dispersion of the M Series is the innovative Balanced Mode Radiator (BMR), reported to be a favourite speaker technology of Ken Ishiwata, a brand ambassador for Boston Acoustics. Ishiwata is one of the most influential people in the high-end audio industry and a crucial figure in the development of the CD. The BMR is utilised in the MSurround and the MCenter products in the Boston M Series family.
