FS: Ambience 1800 Reference

Recommended Posts

Item: Ambience 1800 Reference
Location: Buderim, QLD
Price:  $4900
Item Condition: 9/10 (One mark shown in photos)
Reason for selling: NLR (Too many speakers)
Payment Method: Pickup - Cash, Paypal, COD Only
Extra Info:

I purchased these brand new from Carlton Audio in May of 2018  as the standard edition, I then contacted Tony Moore the following month and had them upgraded to the reference edition (upgraded crossover and wiring) at a total cost of $8500.  When positioned correctly they are incredibly revealing  and smooth to the point you feel like you're in the studio. They are truly three-dimensional which is something I have never heard with a conventional cone driver. 


I am selling these due to purchasing new speakers that work better in my new lounge room. Originally my plan was to keep to them and setup and dedicated listening room but this won't be happening for some time so instead of collecting dust they need a new home. 


Will come with the original manual however I seem to have misplaced the binding posts as I have these bi-wired as per Tony's instructions.


Happy to demo for serious buyers.


Prefer local pickup but can ship at buyers expense. (I have the original crates)

Wow, is that a CAT JL2 driving them? 


These speakers will tell you everything about the character of your amplifier. They demand an amplifier with plenty of current and as Alltheambience says create an absolutely fantastic sweet, detailed and dynamic soundscape with depth, width and focus when correctly positioned. They are hugely underrated Australian speakers and these would represent 30+ years of ongoing development by Tony Moore. Fabulous speakers.

Oh my, what a combination!


I have been searching for the perfect partner for my Ambience Reference 1600’s, 96 dB version. (See “Rocking the Granny Flat”.) Now that would do it, 16 x 6550’s!!! Can only imagine the results of that match. 

What are the subs you are running?

Yes, its an amazing combination, somewhat emotional when the right piece of music is played!

The bass drivers really appreciate the grunt from the CAT. (I must admit, I will hang on to them if i can't get the right price).


The CAT has had its main board upgraded as the original board would blow as soon as it blew a tube. With that the 6550's were replaced with KT120's. I cant comment on the difference as I've only heard it with the new tubes. 


The subs are made by Greg Osborn. They're the epitome bass cabinet, however they have a Focal 12" flax driver powered by Redgum's RGSW2.

      Item Condition: Excellent Shipping Options: Pickup is available,I can ship this item Suburb or Town: Ivanhoe East State: Victoria Payment Method: Cash, Bank Transfer or Paypal Reason for selling: Selling for a friend who has upgraded Further information: This beautifully built combination is also available separately at (PM for Prices)
      The REF500S is the newer of the pair and therefore priced higher, being a current model with RRP over $4K, but still cheaper than I've seen anywhere else. Ultra compact but very powerful, rated up to 250W RMS @ 8 ohms/400W RMS @ 4 ohms, with balanced and RCA inputs. The quality of Bel Canto is demonstrated by outstanding specifications such as S/N ratio of 125dB. The combination of the latest advanced components for the custom input stage such as Caddock resistors, ultra-low ESR decoupling capacitors, heavy gauge all-steel chassis for microphony reduction and low noise regulated power supplies together with a highly efficient output stage reveals all the subtle nuances of music with extraordinary impact and resolution. The elegant switching output stage eliminates thermal distortion mechanisms caused by changes in operating temperature while heavily regulated switch-mode power supplies generate little heat. This makes such a compact and powerful device possible, saving space as well as shortening the signal path.
      The DAC was as expensive model with comprehensive features for its size, including inputs for AES, USB, Toslink and SPDIF with sockets for coax or BNC, plus balanced and RCA outputs. One of its most useful features is the ability to switch between fixed and variable output. When used with a preamp, fixed mode applies, but when purely digital sources are used it can drive a power amp directly with volume controlled by the variable output setting. Besides transferring more information via a direct signal path, this configuration saves the cost of a separate preamp with associated cables and results in an incredibly cost-effective, compact stack as in the photos below. In listening tests I've found this DAC to be particularly smooth, making it an ideal partner for the detailed and dynamic presentation of the REF500S. It comes with all original packaging, an easy-to-use remote and manual.

      Item Condition: As new, but "B stock" - see below Shipping Options: Pickup is available Suburb or Town: Adelaide State: South Australia Payment Method: Bank transfer, Cash Reason for selling: NLR - dismantling study rig Further information: 
      These were purchased new from Denis White in Adelaide as "B-Stock" in July 2018
      Some of the 1st shipment of S40s had a cloudy spot in the clearcoat because they were bagged too early while the lacquer was incompletely dry.
      This pair's imperfection is only visible in bright daylight at a precise angle ( I tried to photograph this, but you really can't) and only if you know what you are looking for
      Otherwise they are in as new condition. They have warranty until Jul 2026.
      They have lived in my study, grills on, never exposed to sun, driven rarely by my Luxman integrated (also for sale) for which they are a sublime match.
      Surprisingly they were also excellent with Devialet, especially as there is an S40 SAM profile.
      I preferred these to the higher range Dynaudio standmounts as the tweeter sounds smoother to me, without appreciable loss of detail
      Stands not included in the price
      I have the original packaging

      Item Condition: Excellent Shipping Options: Pickup is available,Audition is not available, but in-person pickup can be arranged with limited personal contact,I can ship this item Suburb or Town: Sydney State: New South Wales Payment Method: PayPal, cash on pick up Reason for selling: NLR Further information: I have 2 X sets of Chord Indigo Tuned Aray interconnects for sale in 1m length and both are RCA to RCA connections. **(Price is each set)** RRP $2,800 each
      Well renowned for their detail, timing, wide sound stage and controlled powerful Bass, these interconnects are a huge leap forward from the Signature Tuned Aray I previously owned and only a very slim difference in performance from the Sarum Super Aray which I auditioned for 2 weeks but didn’t see the need to change to the Sarum as the Indigo were just as impressive in every way. I believe this is why the Indigo line has been discontinued as they are too similar to Sarum in performance. Near perfect condition ( I am very fussy with all of my equipment) Original boxes in excellent condition also. Highly recommended.
