I’m currently mid way through updating my AG Duo Omega which is taking me longer than I thought and has exceeded my modest budget I’d allocated to the project due to discovering further areas for tweaking.
The binding posts have been changed from very basic WBT brass/Chrome to Audio Note Ongaku Silver and for the tweeter I had to use WBT 0705Ag. The tweeter crossover connected to the old binding posts via a brass bolt and star washer biting into a trace on the pcb, not the ideal connection. The new WBT allow the solder tag to be bent over and solder directly to the trace. At this moment in time I can not afford to change the cap to a Deulund SnCu and inductor to Jantzen Copper Foil in wax but will prioritise this next year.
Internal wires to drivers will be soldered directly to the driver wires and crossover and ‘grub screwed’ to the Mids posts. These links were kindly made for me by Mark Coles from Sablon Audio and replace the factory silver plated copper links.
The metal horn tubes are now damped carefully with sound deadening panels as in new production Duos.
Moving on to the Bass amps is where my initial upgrade thoughts started and I knew I had to remove the generic IEC inlet for an Oyaide R inlet. I’ve found this inlet to be both great sounding and economical. On opening the amp module I could see two fuses on the pcb screaming SR Blue fuse please!. There are also 4 opamps that could be changed to Burson opamps but I decided to leave these alone. All the caps looked fine, though I was tempted to change the 4 10,000uF caps for Mundorf MLytic AG, so left them alone.
Outside of the Duos I’ve upgraded my Sablon speaker cables to Bocchino spades like Spiritofmusic has done and upgraded the power cords to Prince Sablon Bocchino terminated cords.
I should be finished and back up and running in a couple of days and will post some comments but with so many changes and so much burn in going on it will be hard to allocate any changes. And, if it all sounds horrible I’ll tell you straight.
