Wow!

Thanks! I built these intending them to stay, so I put some effort into it. They're too good to be sitting around unplugged so hopefully there is a good home for them to go to :)

I made a set of lxminis a while ago. Amazing sound quality. I can only imagine what these must sound like

Out of interest, is that all that's involved (and what difference would it make?)

Yes, pretty simple to change, there is a 4 core wire running through the upper baffle mount from the speakon at the base which connects to the crossover on mine.

 

So remove the crossover and directly connect two of the drivers, the third driver then needs a separate two core cable run up the outside of the frame. Load up the 4 way DSP program and connect the extra amp to the new two core cable (making sure to get the right drivers connected to the DSP program). I used banana connectors on the spare amp to make it simple to upgrade. 

 

I don't think the difference would be huge but it does allow each driver to be EQ'd separately and time aligned individually. SL made new measurements and created the LX521.4, I translated those over to the Najda. He thought it was better and it no doubt is! How much I can't really say.

Buy with confidence. 

 

I bought the Orion’s that Fluid had for sale. The system was delivered yesterday. Impeccably packed in 4 boxes. Inspite of the courier companies best efforts - one of the speakers was delivered upside down in spite of clear labels - everything was in perfect condition. Fluid knows how to pack his speakers securely.

 

The build quality of the speakers / electronics is phenomenal, and was a steal at the asking price. 

 

If you’re  considering this system, you cant go wrong. super value at half the asking price of other LX521’s that have been on sale.

 

GLWTS

      Our Image T5 Tower Loudspeaker has a slim dual-woofer transitional two-and-a-half way design with identical 5.25-inch woofers and a one-inch titanium tweeter that delivers reproduced and refined sound. The T5 Tower Speakers offer tonal, spatial and dynamic accuracy in a well-designed package with stunning finishes and subtle curvature that will easily into any home decor.

      Item Condition: Excellent / as new Shipping Options: Pickup available but audition is not available.,Shipping is available at agreed cost. Suburb or Town: Sydney State: New South Wales Payment Method: Paypal, EFT, Cash Reason for selling: Raising funds Further information: 
      Relisting with a large price reduction - now significantly below the last one that sold on SNA earlier this year. 
      The key selling points of the Simaudio Moon 760A are:
      1. Brilliant sound quality - pitch black backgrounds, and complete control of music throughout the spectrum from bass to treble
      2. First 5W are Class A - so a great match for high efficiency speakers. Can also be used as a headphone amp for very hard to drive headphones
      3. 130W into 8ohm (in class A/B)... with potential to bi-amp. So can pump serious power for the vast majority of loudspeakers
      4. Extraordinary build quality - will last a life time, and has been looked after with a great deal of care. It also doesn't run too hot, which hopefully helps with longevity
      5. Weighs only 20kg, so is pretty user friendly to install etc. And looks rather nice in silver/black two-tone (perhaps the only unit in my set up that hasn't been called 'ugly' by the commander in chief)
       
      In Aron Gerrecht's words:
      "During my time with Simaudio’s Moon Evolution 760A, I was reminded of what an exceptionally well-engineered and -constructed amplifier can provide, aesthetically and sonically. The finesse with which the 760A consistently balanced power, transparency, dynamics, tonal colors, and dimensionality, all against near-silent backgrounds, was spellbinding... Heck, even if you’re not in the market for a new reference amplifier, go hear firsthand what the 760A has to offer -- it’s the best-sounding standalone power amplifier I’ve heard for anywhere near its price of [US]$8000. Recommending it is a no-brainer."
