Reason for selling: No space, happy wife happy life.
Payment Method: Pickup - Cash, Paypal
Extra Info:

Selling this system with great regret, but it's gathering dust. Having designed high-end loudspeakers professionally for many years, I created this constant-directivity dipole system from the ground up from the very best components available.


  • The RAAL dipole tweeters include amorphous core, a 20uF for protection, and the addition of felt to improve the directivity match to the mid-range.
  • The tweeters and 4" midrange are suspended from a frame, avoiding baffle resonances.
  • The 12" mid-bass' are mounted on a small baffle (18mm ply) to increase low-frequency extension.
  • The 21" woofers are mounted in H-frame cabinets (18mm ply) to increase low-frequency extension.
  • The MiniDSP includes all crossover and equalisation settings. However, no amplifiers are included, so 8-channels of amplification and some gain adjustment will be required. I drove the tweeters/mids with 180W/ch and mid-bass'/woofers with 350W/ch pro-audio power amps (already sold).


Sale price for entire system including drivers, frames, baffles, cabinets, DSP w/ original settings: $3,200

Separate pricing

Tweeters: $1,300 for pair

Mids: $400 for pair

Mid-bass': $600 for pair incl. baffle

Woofers: $800 for pair incl. baffle

MiniDSP: $400

Hi John,


Yes they are still available; as mentioned in the above post, one of the ribbons has some superficial creasing on it. Are you in Sydney? PM me for more details if interested.

      Item:                          Line Magnetic LM-219IA Integrated Amplifier with upgraded valves (see below). 
      Location:                   Melbourne
      Price:                         $4,300 - I think this is a good price given that it includes over $2k worth of valve upgrades and is not a grey import -  genuine Australian import version rated at 240v
      Item Condition:       Excellent
      Reason for selling:  Still too many amps
      Payment Method:  Pickup - Cash, Paypal (buyer pays fee), Bank Transfer
      Extra Info:                This is a genuine Australian 240v version that I bought new from Mcleans Audio in July 2018 
      I have upgraded the 845 and the 12AX7 tubes. The originals are included and have very little use.
      The upgraded tubes included are:
      2 pairs of Psvane 845 Western Electric replicas (that's 4 tubes in total). One set has been unused since I bought it here from a fellow SNA member (the photo is from that advert). Two new pairs would set you back about A$2k 1 pair of Sylvania 5751 which I found to be significantly better than the stock 12AX7s  
      This thing is a beast (about 70kg packed) so I'd prefer to sell locally.
      I do have the original packaging so if no local interest I will consider shipping at your cost (and risk)

      Extra Info: I bought this amp last week of fellow SNA member to power my PMCs. I really enjoy this amp but for multiple reasons have decided to let it go
      The Good
      - Sound quality Clarity and Detail - Wow believe all the reviews this amp is transparent and detailed. There is none of the "vailed" effect you get from other amps. Had me listening to all my old songs and hearing things i didn't notice before.
      -Power - Class A and Class D = SPL even though it is the baby of the range to drives my PMC 25.23 with ease. I suggest any stand-mount or small / medium floor stander would not be an issue.
      - Configurability -  Multiple set ups can be created and saved via the online configuration tool and loaded onto an SD card
      - Build quality and design- Seriously solid piece of kit, all hardware is highest quality and has plenty of wow factor
      The Bad
      -While the configurability is good, it does mean you need to tinker with this amp to get the best out of it, great if you have plenty of time but for me with 2 kids and a demanding job I don't really have the time to tinker with SAM settings, crossovers, firmware versions, power options etc.
      - Can only connect 1 analogue input. I use my amp for 50% music / 50% HT so need to have my AVR connected via HT bypass, this means I can't connect my external DAC or a turntable if I wanted. I have it installed in a AV cabinet so difficult to get round the back and pull out chords
      - Cant see the display when i have it sitting in a normal cabinet, not a big issue but a little annoying
      - Fingerprints - I have a teenage son who also loves music and while he is very respectful of my gear he has teenage fingers that are constantly leaving marks on the unit and remote
      So while I would love to keep this amp for its sound quality and wow factor it just is not the best fit for my lifestyle, Hoping I can recover what I paid and as this is the cheapest devialet in Australia right now and they don't come up very often price as firm.
       Happy to demo if your in Melbourne,  have all original packaging so happy to also post interstate at buyers cost.
      I may be interested in a trade to Bryston B135 SST2 / 3
