McLaren Audio History

Mclaren Audio Brief History

Mclaren Audio was first manufactured in 1976. David Burger a director of Zetka Industries lived next door to a well know audio retailer, John Button. John suggested that there was a need to fill some gaps in the audio market and Zetka might have the electronics expertise to produce it , specifically Phono preamplifiers and graphic equalisers. Further to this he suggested Paul Mclaren would be able to contribute technical direction for the products.

Paul did this and with some negotiation, the McLaren brand was established with the 101 moving coil pre-amplifiers, the 201 Moving magnet RIAA pre-amplifier and the 301 Graphic equaliser.at first on a fairly small scale for the local New Zealand market, this continued until 1982 with the product range slowly expanding. In 1982 a review in Australian HI FI prompted the design and consequent manufacture of the ZPE range of professional power amplifiers primarily for the Australian market.

My space in 1981

The scale of the Audio operation was expanded to deal with this large increase in demand and provided the incentive for further research and development.
In 1985 the 02 Mclaren series was launched on the New Zealand and U.S. markets with initially a slow response. However after some cosmetic redesigning the product was accepted into a number of overseas markets. (U.S. Hong Kong, Canada, France, Italy, Australia, Germany, Taiwan)

The Mclaren Audio range has also been reviewed by a few international magazines including Audio, The Absolute Sound, Australian HI FI, La Nouvelle No 10 and HI FI Heretic.

The scale of the Mclaren operation has reduced after 1981-1990 years but still has strong reputation in the N.Z and overseas markets.

From 1993 I have developed a series of services in modification of Compact disk players addressing some major deficiencies. This also led to a modification/upgrade service for McLaren amplifiers again addressing problems which were inherent in the earlier designs.

In 1998 I moved to Taipei Taiwan and closed down the production of McLaren Audio in favour of family life with my new-born son Jason.

After my return to NewZealand and taking on other employment I continued to upgrade McLaren amplifiers on a as required basis.

I was asked by a colleague in my day job in 2012 what amplifier he should buy so I recommended he buy a used McLaren, which he did. He then decided to purchase new speakers and went to a store to audition some. Leaving the store dissatisfied with all the amplification offered to audition them, he requested a visit using his McLaren A150 to audition them again. The store agreed.

He relayed the story to me, that he set up the amplifier and waited for one store sales team to move away with another customer. Then as soon as he started streaming music through his phone, he had an audience. Being asked where they could get one of those (A150), Could they pull up a couch and have a decent listen. At the peak he said there were about twelve people.

On hearing this story, I though “this is a nearly 30-year-old amplifier standing head and shoulders above modern offerings I know more about electronics and physics than I did when I designed it. I want to have another go at this”.

I did and the results were very quickly well beyond my expectations. Refining these concepts has led to the release of a series of upgrades that take McLaren amplifiers that are still competitive in their standard configuration with modern amplification, taking them to an unexpected level of performance, while at the same time not requiring new materials and recourses use. Please take a look at the upgrades page to see what’s on offer.
