LUXMAN-L-350AII - The Modern Classic !

LUXMAN-L-350AII

Similar to its L-550A II predecessor, the L-350A II is a basic model of an integrated amplifier with pure Class A amplification method that features rich sound reproduction ability and allows enjoyment of music at all times. Based on years of experience and the application of the latest materials science technology, Luxman extensively uses filters, shielding, ferrites and radio-signal absorbing materials to cut electrical noise. We also use FRP (Fiber reinforced Plastics) resin, loop-less box construction and other rigidity- enhancing measures to suppress mechanical vibrations.

BART LOCANTHI

Bartholomew Nicholas Locanthi II (White Plains, New York, 1919 – Glendale, California, January 9, 1994) was an audio engineer and leading expert in the US pro-audio industry in the 1970s and 1980s.

Bart Locanthi graduated from California Institute of Technology in 1947 with a B.S. degree in physics.

From 1947–1960, he mostly contributed to analog computers.

In the late 1960s, Bart Locanthi developed the "T circuit", an output configuration for solid-state power amplifiers that became a standard in the industry. He received three US patents for his pioneering work on transistor amplifiers.

Bart Locanthi became the Vice President of Engineering at JBL in 1960. It was under his tenure that the JBL L-100 Century, the world’s most popular loudspeaker in its day, was manufactured. In 1975, he was named a Vice President of Pioneer North America Development. While at Pioneer, he and his team of engineers designed the HPM-100 loudspeaker as an "improved" JBL L-100 Century. It was also at Pioneer that he was deeply involved in digital development during the early years of the compact disc

He died on January 9, 1994 in Glendale, California after a long bout with pancreatic cancer.

Bart Locanthi was a Fellow of the Acoustical Society of America and the Audio Engineering Society (AES); he was awarded posthumously the AES Gold Medal in 1996. Locanthi was active in many AES affairs, he served as papers chairman for conventions, member of the Board of Governors, and served as president (1986–1987).

Pioneer HPM-100 Vintage Speakers

My Pioneer HPM-100 Vintage Speakers 1975

"""The Pioneer HPM-100s were built by former JBL engineers to do one thing, and that was to be a better sounding speaker than the JBL L100. I think they admirably did their job, as the HPM 100s are one of the best sounding speakers ever built. I know this is saying a lot, but this is the general consensus among many people in the Hi-Fi Industry. These speakers have just the right balance and warm tones. These are amazing sounding speakers.
These particular Pioneers work 100% and sound remarkable! The depth of the sound of these speakers is incredible. Breathtaking sounding speakers."""
