An innovative transmission line loudspeaker

Ron Newbound and the DIY group of Melbourne Audio Club have been developing a new transmission line loudspeaker. As a group they came up with a design using tapered Sonotube pipes within the enclosure. Drivers and damping have been installed, crossover design and tweaking are planned for the next meeting. (On April 1st. Not an omen I hope).
If you would like more information come to the meeting Wednesday 15 and join the group. Also enjoy the demonstration of Hugh Dean’s AKSA amplifiers and Kef 105 reference loudspeakers brought by Ray of the Hi Fi Exchange.
8pm in the Willis Room, Nunawading Civic Centre. Third Wednesday of every month

No Melody at the Audio Club! Wed 19 October at the Willis room 8pm

MELODY AMPLIFIERS will not be able to be at this meeting, more details in the nextost.

Melbourne audiophiles were heard crying for joy as the gloomy clouds of winter parted. The gentle glow from the sky began to warm their hearts with anticipation, for this year they are fortunate to experience two Hi-Fi Shows for the year. This month the Australian Hi-Fi and AV Show returns to Melbourne, showcasing at the Rialto Hotel.
Back in July, the Melbourne International Hi-Fi Show was a first for the StereoNet guys. Not only was it their first time in organising a very successful show, it was also a first for Melody Valve Ltd to exhibit all of their new models of amplifiers. If there ever was an award at a Hi-Fi Show for an “Exhibitor who tried the hardest to impress”, then Melody would be the clear winner.
Melody will be demonstrating two systems for the club, from their new range of Everest Amplifiers. The first model is a 75W Class AB amplifier, the Everest 120, which uses a pair of KT150 tubes per channel. This unit will be partnered with a pair of classic Yamaha NS1000 speakers. (Kindly provided by our Editor) The other amplifier is a pure Class A model. The Everest 845 pushes out 28Wpch from, you guessed it, an 845 tube. It is driven with a 300B, all are Western Electric valves. A second set of speakers from “Hi Fi Exchange” will complete this system. A pair of Whatmough 502’s is a particular brand that is very familiar among the Club members.
Melody was founded back in 1977 by a group of Chinese based audiophiles now living in Melbourne. With a small number of models, finished in “gun metal grey”, they established their first sales out of Bayswater. Now with their third generation of amplifiers looking more esoteric, they have established themselves in Europe with a stable of eight models. With plans to expand further, this small company has come a long way.
Nick Karayanis – Program Co-ordinator.

To add to Nick’s writeup: There are still members who would remember a club visit to the Melody showroom in Bayswater many years ago. At that time the prices seemed very realistic for the sound and build quality despite some disparaging (rude) comments by some of the visitors. In the years since I have sold a number of Melody amplifiers which not only sounded really good but were 100% reliable. I still regret missing a Melody 2A3 that came into the shop while I was away. Maybe one day…

Good News about the Hifi Exchange

Even though the exchange is being sold, the new home (Rookes Road Nunawading) will welcome the Saturday coffee club! The good news part is that I will not be at the new Exchange for at least the first few Saturdays-I will still be at the Camera exchange while John will help with the transition for at least the first month.

The move to Rookes Td will take about three weeks, I believe a coffee machine is on the list.
Nothing much will change, the website goes with the business, and much of the existing stock will be available. The servicing and testing equipment and a stock of valves will also be available. As I learn more I will keep the blog up to date.

On a different note, if you are interested inKondo, Vitavox, TAD and beautifull woodwork, have a look at the 2 million dollar system on Mike Fremer’s Analogue Planet (Stereophile) Bangko show report. After you’ve read the article put your name down to visit the show June next year.

Happy 21st Redgum!

The next MAC meeting Wednesday 20 May. Here is a preview of the Redgum presentation. This will be very popular meeting, there has been a lot of interest in Ian’s designs, and he and Lindy usually provide the most interesting and entertaining meetings. Meetings start at 8PM in the Willis room.

REDGUM AUDIO turns 21

Melbourne Audio Club has another world first. To celebrate the 21st anniversary of Redgum products in Australia the club has invited Ian Robinson and Lindy Gerber to present their new flagship monoblock amplifier, the Redgum “Magnificata”. This will be the first public demonstration (yes, a world exclusive!) from their newly named Amplifolia range of amplifiers.
The Magnifica has been purpose designed to power ultra-low impedance speakers, and then some more. A few Power Output stats tell the story… Into 8ohms – greater than 350W/ch (Transient Power 500W). Into 4 ohms – greater than 900W/ch (Transient Power 2000W) All the input connectors are hand – wired with OCC single strand, solid core Silver wiring.
Running off these new mono blocks, will be Redgum’s gorgeous looking Regnans Floorstanding Loudspeakers finished off in a high gloss Redgum wood veneer. The Regnans are a 2.5-way design featuring 2x170mm drivers with a 25mm soft dome tweeter, all sourced from SEAS.
Speaking of source, the front end for the system will be Redgum’s tried and trusted RGCD5ENR CD player, as well as their DAC. In addition a Blue-ray Player fore Hi-Res discs and files from a laptop to round off the music presentation.
It’s been some time, (more than a decade) since we last had Ian and Lindy at a club meeting. With a long and enviable career in the Hi Fi Industry, I am sure this evening will be an impressive demonstration of well designed Australian audio equipment.

The magic combination. Goldbug Briar cartridge on Victor deck, Shindo Massetto preamp and the Mondo Ongaku copy. Tannoy 15″ Reds in Shindo made Autograph cabinets. For CD and SACD the high end Marantz.
For your delectation a pair of Lowthers in Alfredo cabinets.

MELBOURNE AUDIO CLUB 19 FEBRUARY.

VAF speakers demonstrated by Philip Vafiadis who founded Vaf Research more than 35 years ago!.

What is it that makes South Australia the birthplace of many innovative high end audio products? Other than Vaf there are Krix and of don’t forget Halcro electronics.
Amplifier will be the Electrocompaniet Ampliwire 100, and and Audio Research LS15 preamp. Source will be the Oppo again. The sound of the Oppo and Pre and power combination should be detailed but not clinical, should be a good partnership with the new Vaf speakers.

An excellent demonstration, VAF have made a good sounding well balanced speaker for under $3000. Philip explained the design decisions for using 6 drivers 3 way. The baffle is designed so that with a first order crossover the phasing is consistent at the listening position. Claimed to be easy to drive and with high efficiency, many of these speakers are being driven with Earle Weston’s valve amplifiers.

September Melbourne Audio Club meeting

AKSA amps  presented by Hugh Dean including his latest, first half of the meeting with the 100 Watt Aksa, then the new all MOSFET version which sounded even better. 80Watts, but an open yet pleasant sound, with a some of the valve sound that Hugh was trying to achieve. Well done, and selling for $2200.

Speakers were the Triangle kits the Nick and Ron made some time ago, also sounding pretty good in the difficult Willis room. Great selection of music provided by Nick; lots of compliments by the audience on the music chosen. Even applause from the floor after a particularly good track. Tough house!

Thanks Hugh and Nick.

As usual 8pm at the Willis room in Nunawading Civic Centre.

Arthur Rapos and Elektra

(Wed 17th) Arthur presented his newest range of pre and power amplifiers at the Melbourne Audio Club.  |Fairly small turnout, but it was interesting to hear Arthur’s design priciples and how he ensures the lowest possible distortion using the best sounding components as well as the layout, thus reducing magnetic and electrostatic coupling. The sound was interesting using a Cambridge CD player and Sonus Faber speakers. Nick provided the discs which were very interesting and wide ranging. By the way, I\m sure John has a couple of Theatrons at the Hifi Exchange, open as usual Sat .
