      Item Condition: As new (10/10)

      Extra Info:
      Bought in April this year from a European authorised dealer  to power my Usher BE-10 speakers but the ushers are so efficient they don’t benefit from a lot of power these behemoth can put out and I need money for a Japan holiday. Australian retail price for these is over $20,000; 

      Mark Levinson No. 531H Monaural Power Amplifier 

      The No 531H and No532H are both true mono-block designs with independent power supplies for each channel and are rated at 300W per channel into 8 ohms. The transformers and power supply designs deliver unsurpassed dynamics and transient responses for today’s demanding audio formats and provide stability with even the most difficult to drive loudspeakers. Fully differential circuitry ensures that balanced input signals stay that way throughout the signal path and traditional Mark Levinson “Hurricane” binding posts offer secure termination to the loudspeaker. 

      The four amplifiers in the No500H Series are the definition of truly outstanding performance in their respective categories. Drawing from the Mark Levinson heritage, while utilizing a new, straightforward, balanced, current-feedback design creates a new series of amplifiers that must be listened to in order to be fully appreciated. The final result is impressive even for the Mark Levinson high standard of excellence. 

      Main Features 

      •Reliable, high-power in four different channel configurations provide ideal solutions for any system 
      •Isolated chassis and signal grounds minimize noise, optimizing detail, even at low listening levels

      •Ethernet and 12V trigger control capability for system integration 

      Inputs one balanced XLR input per channel; one unbalanced RCA input per channel 
      Speaker Connections one pair “Hurricane” loudspeaker outputs with banana-plug sockets per channel (banana-plug socket not available on the 230 VAC models)

      Item: Concert Fidelity ZL200 monoblocks (price reduced)
      Location: Melbourne
      Price: $8500
      Item Condition: Excellent 8/10 on Audiogon scale
      Reason for selling: Reconfiguration of system (for balanced operation)
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info: purchased second hand around 5 years ago. Rarely used and always used with PS Audio conditioner. New price for these were $48,000 US ($70,000 AUD!) - very expensive (and heavy) mono blocks. You will not find any power amps of this quality near this price. This amp received the Absolute Sound 2012 Editor's Choice Award.
       
      The unique sound of the ZL-200 is aptly described by Mr. Harry Pearson: "These monoblocks are the first solid-state amps I've heard that sound like a tubed unit, and by that I mean a very good tubed unit, on the order of say, the best conrad-johnson amp (vide, the ART III) but lacking the golden glow of the CJ sound, thus rather more uncolored than most, if not all, of the transistorized competition. It has the dynamics of good tubed unit, the focus on instruments and the sense of an ambient field that is characteristic of the old William Z. Johnson design for Audio Research.

      Item:   AVM Ovation MA 8.2 Monobloc pwr amps
      Location:  Melbourne, Vic
      Price:  $16,000
      Item Condition:  Excellent
      Reason for selling:  Upgraded to valves.
      Payment Method: Pickup - Cash, Paypal, COD, Bank Cheque, electronic transfer.  If Paypal, buyer to pay all fees.
      Extra Info:
       
      These were Marc Rushton's power amps.  I bought them in Oct 2017.  I said I was never going to have valve power amps again but I changed my mind after I heard the AR Ref 160M which I bought.  But I would've happily stayed with the AVM MA 8.2.
       
      The AVM monobloc runs the AR pwr amp close.  At $16k the AVM MA 8.2 is an affordable end game power amp.  RRP was $44,000 for both ($22,000 each).  It is rated at 600 watts RMS.  It will drive anything with finesse.  It is a low noise, low distortion design.
       
      This is a very good price for these amps.  If you want to spend less, there is the Holton monobloc listed on this site for $15,000.  
       
      It is Germanic black as you can see by the pictures.  It is so black even the white parts are black.
       
       If not pickup, buyer to arrange courier.  Gross shipping weigh each at about 45kg.  W58cm x H38cm x L57cm.  Shipped in haulage case as pictured.

                 Purchased this amp new with Hulgich Ella II speakers. Same amp was used with Hulgich speakers to win best sound in show at 2017 Melbourne Hi Fi Show (minus the new Rev D buffer upgrade which provides even better bass response and other goodness)   Handmade in the UK it’s not a cheap class D. Great attention to detail in all aspects of its production. 
                  Very clean sounding amplification with 400 watts / 8omh it will drive any speaker. 
       
                  Ever wondered how good class D can be? This is a good place to start! 

                  Current model (same) will set you back $3800+ 
                  Demo available.
