Amongst these, defective oxidative phosphorylation arose as the hallmark of mitochondrial disorders. Over time, mitochondrial energy metabolism has been discovered to be influenced by a vast number of proteins with a multitude of functional roles. The concept of a mitochondrial disorder was initially described in 1962, in a patient with altered energy metabolism. 2Institute of Neurogenomics, Helmholtz Zentrum München, Munich, Germany.1School of Medicine, Institute of Human Genetics, Technical University of Munich, Munich, Germany.The industrial design of the amplifier is actually quite unique they often have a very industrial looking chassis and design because they were meant to be hidden inside a console.Lea D. This type of amplifier is prized by those who love to modify or restore amplifiers from the period. When someone guts ugly (with some mid-century exceptions) 1960’s wood or fake wood console stereos for the tube amplifier within. We paired it with an early 1960’s RCA stereo console pull. The best thing about the Model 300 is that most people buy it to use as a preamp because of the superiority of Holman’s internal phono preamp. It’s a very focused sounding receiver with a decent amount of control in the lower registers. For the price, Henry Kloss and Tom Holman executed the design of the Model 300 quite well. Needless to say, my son and I were both impressed with my 1980s post punk music and his Hazel English and Beach Bunny. I normally use “loudness” and with the 300 I really didn’t need to. The clarity was excellent, and the low end was tight even with the “loudness” off, and this pairing allowed us to run the volume dial to almost 75% of its range with very little distortion before I dialed it back. The amplifier outputs a mere 15 watts/channel, yet it drove the loudspeakers quite effortlessly. The Model 300 proved to be a low noise and low distortion receiver at a rather affordable price point.įor my listening tests I paired the Advent Model 300 with a pair of Dynaco A25’s from the same period. There were so many technical improvements in it that Holman delivered a paper on it for the Audio Engineering Society. The phono preamp alone is why most people purchase this receiver. The price of the Advent 300 just went up. He’s one of the most respected sound engineers in the world and tens of millions of people use his products every single day. He also won an Oscar in 2001 for Scientific and Technical Achievement.

Holman designed the very capable Holman Pre-amplifier, but he changed the movie experience as we know it with the invention of Lucasfilm THX.įast forward to 2021 and we find him at Apple developing products like the Apple AirPods Pro and leading the development of their other audio products and streaming technology. If you love movies, his name should immediately recognizable. They did eliminate the AM tuner section, but then added an auxiliary input and a brand new phono preamp designed by their Chief Electrical Engineer, Tomlinson Holman.
A lower retail price means cheaper parts and construction quality, but Advent created something rather worthwhile. Kloss had a huge impact on the affordable loudspeaker category and his products have been part of the vintage audio landscape for decades.Īdvent decided in the 1970s to enter the audio receiver category and the Model 300 was introduced into the market after 3 years of research trying to perfect a receiver that, as the catalog states, “most people will value under real listening conditions at home at a price well within the lower half of the current range.”ĭesigning any piece of audio hardware is a challenge, but it takes a very competent designer to engineer a more affordable piece of equipment that sounds good and is reliable. It’s not the easiest product to locate but it has proven to be quite a surprise and further proof that there are some excellent vintage amplifiers available outside of the Marantz and Harman Kardon products that are very popular.Īdvent was founded by audio visionary, Henry Kloss, after he left KLH in the late 1960s. We’ve already covered them in a previous column but this week I want to focus on the Advent Model 300 amplifier. I own a pair of the Advent loudspeakers and think that most people interested in affordable vintage audio should own a pair if they can find them for a decent price. Most vintage audio fans know Advent for the Large Loudspeaker and nothing more. Outside of audio circles, it is not well known that Advent manufactured audio hardware other than loudspeakers.
