Price: 260
Item Condition: new 9/10
Reason for selling: other priorities in my life ATM
Payment Method: Pickup - Cash, COD 

BankTransfer Pickup preferred.
Extra Info: Skimp on the quality of the components in the bass section of your passive crossover and overall sound quality will be compromised as all other signals will be filtered by the quality of passing through these components. That is the simple inconvenient truth that many loudspeaker manufacturers like to avoid confronting. This is the Achilles heel of the standard kits and Rogers AB1 bass enhancement module as I like to call it. It really doesn't go low enough to qualify as a subwoofer.

The kit consists of  X 2 Erse 17 MH .5 Ohm DCR 500 watt rms inductors  and  X 4 Cross Cap Jantzen 100 uF 400 V polypropylene that are more than a fist full each. Check out the price of these things add postage and know you are getting a bargain that will enhance the performance of your AB1.

Hi Mark I have a pair of Audio Space AB-1 copies which have really impressed me with bass reproduction when properly controlled. I currently have an ME550 MkII being loaned to me while my Accuphase E-205 is in for repairs. 


Would you expect a significant improvement with changing out caps and inductors, are they installed in the AB-1 towers and are there any reviews with standard components changed out? 


Thanks in anticipation, Regards

      Item: Christie HD3 1080p 3DLP with Xenon bulb
      Location: Cherrybrook, NSW 2126
      Price: 2500
      Item Condition: 7/10 (lens small chips, some tiny dots on the projector body as per photos)
      Reason for selling: Upgraded to a brighter model (HD6K)
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info:
      This is a rare opportunity to have such a great projector, way way way better than those sub-10 thousand 4K consumer ones. It is a huge sized projector, weight 34kg without lens and the lens is another 5 or more kgs. RRP around $50000 USD for the projector and $6000 for the lens! It's over 100,000 AUD totally when it was new.
      Selling due to I find a 6000lm HD6K is better fit for my 175 inch screen. Although when use this HD3 for 175 inches, the image, the brightness is already way better than any consumer projector, I feel it will be perfect for 150 inch or so.
      It use 3DLP chips, it's 3X0.95 inch DLP chips. Now a days new 4K DLP projectors are using single 0.47 inch (physical resolution 1080p, yet shift to 4K) and 0.66 inch (premium models with 25XX resolution shift to 4K). So it's like consumer cheap camera VS professional DSLR, even consumer ones got more pixels, it can not compare with professional DSLR with prime lens. With 3DLP chips, there's no color wheels so no rainbow effects.
      The lens is a fixed 1.1:1 (HD) short through lens which can do 150 inches with 4M distance. The lens is massive and very heavy. It has some chips yet there's no visible impact to the image. I have another same model lens without any chip yet can't tell difference when I swap lens.
      It's using 500W Xenon bulb. Which Xenon ones have best spectrum that close to sunlight. So it's not like other UHT lamp or LED or laser that certain color is weaker on spectrum that you need to calibrate the project to have accurate color while it's a lot dim than advertised. Xenon bulb projectors has no such issues and color is the best even better than latest top end LED/laser projectors.
      The projector is around 3290 hours and lamp is 495 hours (1500hours life, if you adjust to lower power such as 350 or 400W, the bulb will have longer life)
      Best color I've ever seen! Very rich, dynamic image. It's not like lots of 4K projectors that the image is 'flat'. This one the image gives you 3D feels. It's like a highend plasma VS  cheap LCD TV. The color, the brightness is better than movie theaters. Great contrast Crystal clear. Resolution wise it's not 4K, yet I guarantee you'll find it's more 'clear' than normal 4K projectors Very bright, best on a 133-150 inch and will still be good on 180 inch screens. Massive sized short throw lens gives you chance to project very large image. (1.1:1 lens) It supports 3D, yet it's frame to frame 3D format that you'll need to have some other video processor to convert from generic BluRay. Yet I've heard someone did it and find the 3D is way way way better than any other projector or the cinemas.  
      Very loud - fan noise around 60DB. Better to build a 'hush box' (which I'll build one in near future). However for the image quality, I can bear with the noise actually. 500W Xenon bulb - can adjust between 350W to 500W yet it use more electricity than normal projectors. Lens got some chips, however there's no visible impact to the image. Xenon bulb is expensive.  
      This projector is for enthusiasts, for those who really want to be moved by the image, and can live with the cons come with the projector.

      Photos: Photos can not justify how great the image is as my camera is not good enough to have grey levels to show all the details.

      Item Condition: Brand new
      Reason for selling: Not used
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info:
      Up for sale is this new/unused AK300 which I bought from Addicted to Audio in Aug, 2016. I had the intention of using this player with a pair or Campfire Audio Andromeda IEM's, but found it more convenient to use my Iphone with my busy lifestyle. Hence this unit and & the Andromeda iem's have just been sitting in their boxes unused since. I auditioned a demo AK300 and Andromeda IEM's extensively at ATA and they proved to be a good combo. The AK300 has good resolution and is on the warm side, whilst the Andromeda iem's are neutral, natural and airy.

      Item: Rotel Michi RHB-10 amp
      Location: Brisbane
      Price: $1,100 plus packaging / postage (if required)
      Item Condition: 7/10 - conservative rating due to the marks.  Performance is terrific.
      Reason for selling:  upgrade (i hope)
      Payment Method: Pickup - Cash or EFT
      Extra Info:
      This Michi amp is unfortunately not in perfect condition - it has marks from previous owners.  I have rated them conservatively and tried to capture any marks in the photos below.  That said the blemishes are not visible from seating distance and still look like the classy wood cheek components they are.  
      The history I know, I purchase these off Trevor Lee in 2012 since then it has been my main amp.  Having said my work takes me out of town a lot so it realistically has been a low use amp since 2012.
      It was serviced by AvDigitech in 2015 and given a clean bill of health.  Greenwagon also replaced the rca connectors about 18 months ago.  
      This Michi certainly held its own against a mates very nice Pass pre/power setup driving my Dunlavy's - in fact I think we were both surprised how well they held their own. 
      Plenty of love and great opinions about the Michi line here on SNA.  This one has most certainly served me well but you can't keep them all.  I know the new owner will have plenty of enjoyable listening hours.
      I do not have the original packaging but I can source some and package it securely for postage / courier.
      Donation to SNA upon sale of course.
      Matching Rotel Michi CD player also available if interested.
