Further Information: Selling my Audio Synergy 300B monoblocs with matching pre-amp which were featured in the March/April 2021 edition of Sound & Image magazine (first photo). These have top of the line components, and put out 18W of pure Class A. Suitable for 4, 6 and 8 Ohm speakers. I used them with a variety of speakers including B&Ws, Ushers, and more recently the Klipsch Cornwall IV’s and La Scalas. The amps have upgraded silver wiring and V caps. If you are looking for that sweet 300B tube sound without breaking the bank, these are for you particularly as selling at nearly third of original cost. Will also come with full silver balanced interconnects made by Clifford at Audio Synergy. Note that the system is fully balanced and has no RCA inputs. Speakers in photo are for illustration purposes only, as I use this as my second system now. The monoblocks are very heavy (25kg kg) so a local sale would be preferred, but shipping could be arranged at cost. Selection of tubes included in sale (see photo for detail on tubes, most of which are NOS except Genelex and Linai tubes). All have very few hours. Any question on specs, please PM me and I will do my best to anwer. No low ball offers please as this is already priced to sell, with the cost of the solid silver interconnects and tubes alone approaching $3000. This is a genuine bargain for a discerning buyer!

Further Information: There are 300B SET amps and then there are 300B SET amps. For those that know Cliff from Audio Synergy this is one of his final evolution of SET amps. It is a two box design. One purely for the power supply and one dedicated to signal, they are joined by umbilical cables at the rear. The signal side has a pair of 12AU7 signal tubes feeding a pair of 6L6 driver tubes before a pair of 300B output tubes. The Power supply consists of two power transformers. The smaller is dedicated to the two 12AU7 signal tubes with the larger more robust handling the 6L6 pair and the 300B pair. Additionally each tube on the signal side gets its individual rectifier tube and choke. There is a lot of copper in the power supply. A pair of 6X4 for the 12AU7 pair. A pair of 5U4GB for the 6L6 pair. And finally the 5R4WGA pair for the 300B pair. What this combination gives you is a scale, dynamics and control over speakers rarely achieved using 300B tube designs. You will get 8 watts of SET goodness!! It will come with the tubes shown in situ and spare tubes for everything, which will consist of - 1 pair Tronal 300B 3 pairs 6L6 as per pics 1 pair Hewlett Packard NEC 12AU7 2 Pairs 6X4 as per pics 1 pair RCA 5U4GB 1 pair 5R4WGA I recently purchased a First Watt F8 with the intention of swapping the two amps in and out with my DeVore O96 Orangutan speakers. The reality is that is not happening, so am offering this beauty up for sale for someone to enjoy. If it does not sell at asking price I will happily keep it as it is wonderful. If you have the right speaker efficiency and impedance these are for you. I do not have any shipping boxes and these are heavy, particularly the power supply so local pick up only, sorry. Very happy to audition for you with my Orangutans. More pictures are available and happy to answer any questions via message. Since the previous listing, I have had the amp checked out and given a clean bill of health by our own @Ihearmusic , so the new owner can buy with confidence.

Further Information: Very sad to see these go, they were to be my “end game” speakers and have kept me very happy for 10 years now. The goal was to build good looking speakers that could be driven to realistic levels by an 8W 300B SET amplifier. Clifford from Audio Synergy here in Perth designed these speakers. We built a prototype pair and it took him a further 3 months to fine tune the sound. The two way was built first, the woofers added later, hence different finish. The cabinets for the two way pair were built and the components installed by Karri Acoustics. The woofer pair cabinets were built by a professional cabinetmaker. Two Way: Cabinets 500 w 850 h 300 d Stands 200 h total height 1050mm. The stands are included in the sale, (they cost me $800- to get made) powder coated steel construction and filled with garnet sand. Very heavy and stable!! Can be used without the woofers, has three ports to the bottom refer pic. Constructed using 25mm HDF board with real wood Karri veneer. Drivers- OEM Tang Band W8-1808 8" Neodymium Full Range Driver with wizzer come removed. RAAL 70-10D RAAL Ribbon Tweeter with Amorphous Core Current replacement of these drivers is $1,648- USD + shipping + duties The 8” runs full range with no crossover while the Raal is crossed at 10.5K with a high-quality cap. Frequency range approx. 50Hz to 30KHz and beyond. Sensitivity approx. 96dB 2.83V/1M Min impedance min 8 Ohm The Woofers: Cabinets 500 w 520 d 600 h Constructed using 18mm Russian Birch ply with 36mm for front baffle. Inside of the cabinets are lined with 3mm copper plate. The external finish is Min Wax. Drivers are Crites (Emminence) CW1526F Steel Frame Woofer – Pair 100 dB/2.83V/1M Current replacement of drivers is $660- USD + shipping + duties Crossover is external as per pics (one inductor) and rolls off at 220 Hz. You can piggyback off the other speakers or run another speaker cable from same amp. In room these go down to about 30 Hz The four cabinets alone have cost me $4,000- and still present as new. These very tube friendly, low power friendly speakers produce an incredibly dynamic, realistic and full sound. Amps beyond 50 Watts probably not suited to these speakers. I am offering these as a package so you can get the full bandwidth but I may split subject to negotiation. The woofers would suit someone looking to build a horn system as the crossovers can be changed very easily. Prefer local sale so you can demo with your amp and make sure you are happy. No shipping boxes are available, and these are each very heavy, for any interstate interest, I am prepared to deliver to pack and send at your risk and for your organization. Speakers like these do not come up very often. These are incredible for the asking price and I am sure a demo will convince you and help you get the best out of your SET or even First Watt type amp. I have had to spend substantially more than this asking price to "potentially" better these. The pricing is firm. Happy to answer any questions by PM and happy to demo with my 300B SET or bring your own amp.
