Our event on 12th September was sparsely attended but we had an interesting time none the less.  There were two slightly modified power amps present, playing via the club's peripherals. 

Jason presented a taste of his idea of development of speakers, all individually driven with its own amplifier, controlled by a digital crossover which can tailor the frequency presented to each speaker but can also time-align each driver

This became immediately apparent when listening to music, whereupon the soundstage became wide and deep

Our thanks to our host, Andrew at his home in Rondebosch

I would have loved this, but was not able to attend. Looks rather cosy!

On 17th October we had a brief demo of REW, using an UMIK and showed the assembled members the frequency response graph and a waterfall graph.   It was enlightening that the waterfall graph displayed different anomolies from the frequency response graph.   But we are not experts at this, and the idea was just to show the principles of operation

The UMIK is available for loan to club members to help with their setup and REW can be downloaded free of charge

The next part of the meeting dealt with JRiver.  As well as providing various tips about adding music to the database and DSP studio, we spent some time on correcting errors

It is frequently found that the meta-data on CDs is lacking in information.   This might apply to a compilation, where you find that instead of the music appearing in one album, all tracks are shown in separate albums.  JRiver's primary sorting criteria is contained in the "Album Artist" heading which you access by right-clicking on the album and choosing Tag

In the demo, which showed 16 copies of the same album art, with one track in each, we clicked and highlighted all 16 pictures.   Then right-clicked on one and chose Tag.   The Album Artist heading showed [varied].   We typed in Audiophile Female Singers and pressed enter.   Clicking on the Refresh button (just above the "E" in the alphabet list above the album cover) showed that all 16 tracks were now correctly assigned to the one album.  The name shown under the artwork is that contained in the Album Artist heading

Another error is duplication.   You add a ripped CD, only to find you already had it.   You thus have 2 track 1s, 2 track 2s and so on.   Click on the heading "Filename" and choose Sort inside groups by Filename.   This sorts the album appear as two separate collections.   You then highlight one set of duplicates, right-click, choose Delete and Delete from disk

Great meeting on 17th. Great demo & explanations. Also great music from the clubs "test track playlist"

Really worth the visit.  :clap:

It's a pity the club meetings are in the Southern Suburbs.

Our advertising manager, Anthony lives in Van Riebeeckshof which is way past the Boerewors Curtain.   You might manage a lift with him.  He reckons a 30 minute drive each way

We don't mind having the occasional meeting in the northern suburbs. 

The venue should have:

Seating for at least 20
The room must not be too live and too large.  About 6 x 10m is fine, carpet, curtains
Safe parking off the street
A wall we can project an image on
Reliable electricity supply
Kitchen - a bonus is cups and saucers, an urn.  (We wash and tidy up)
Reasonably priced  (the NGK costs the club R230,00 per evening, so less is ideal)
Easy access (the NGK give me the keys and the alarm code)

So if something comes to mind and is available on the second Wednesday of the month, we will certainly come and have a look

Our 8th November at The Listening Room, courtesy of Rodney was an outstanding success

Rodney described the philosophy of the British design of Harbeth Loudspeakers, and the sound from the two models auditioned proved this beyond doubt.  A polite "English" sound, not unlike Mordaunt-Short from a few years back, but a much cleaner and transparent tweeter

Our sincere thanks to Rodney for hosting us, the wine and whisky (!) and being able to look around a most interesting shop

The Listening Room is on the second floor at Cape Quarter in Somerset Road and there is very convenient parking inside the building

Seeing this forum heading is "Social Clubs and events" we neglected to show you what the Hi-Fi Club sometimes do after an exhausting audition

Last night we went along to Hudson's Burger House after the event at the Listening Room.   Chock a block full and really loud.   The food is cheap though (Hudson Burger for R60 and well prepared)







And to show that we were where we said we were...
