      Great cables that absolutely sing!! These have been used for only a few hours.
       
      I bought a pair of vintage Yamaha NS1000 XW speakers and ended up using my NAIM NAC A5 cables.
       
      These cables are over $900 RRP. Grab yourself a bargain!

      I chose this new model McIntosh to be the best, and last, amplifier I'd ever need. 
      It's a dream amplifier, hand made in New York and is more than capable of complementing any high end speakers within my budget. 
      Its a regretful sale ... my plans and circumstances have changed and I have to let it go. 
      It is as new in its box. 
       
      Features
      The all-analogue Hybrid design combines the best vacuum tube preamplification and solid state design principles. The valve preamplifier section is powered by two pairs of tubes: two 12AX7As and two 12AT7s.
      Its output stage delivers 200W per channel into 8 ohm speakers, and 320W per channel into 4 ohm speakers.  
      With an output of 200W, it boasts double the power of its predecessor, the MA252.
        It totes two balanced and three unbalanced inputs, plus a Moving Magnet phono input for hooking up a turntable. There's also a preamplifier output for connecting power amplifiers, and you can link it to two powered subwoofers.
        As you can see, it's built like a tank, by hand in New York. The stainless steel chassis is polished to a mirrored finish, and each side boasts vintage McIntosh-styled die-cast aluminium name badges. The logo lights up, and the glass front panel has LED backlighting, so it should look pretty cool in a dark room.
       
      Specifications
       
      Named Best Hybrid Amplifier 2020 by Hi-Fi World
      The final verdict: "The MA352 measured well in all areas. It has massive power, almost no distortion and no weak points... A stunning amplifier in sound quality and dynamic thrust. Visually alluring too." Awarded 5 out of 5 Globes. Hifi World Review
       
      "a buyer would appreciate brand cache (and associated good resale value) while enjoying pride-of-ownership. There’s a sense of confidence in the amplifier’s effortlessness in terms of its power capabilities and its handling of music, how it functions and its overall execution. It offers a rounded set of features. It’s solidly built and assembled. It looks gloriously attractive. Finally, and most importantly, it plays music to very high standards of dynamic realism, tonal accuracy and sheer listenability." Soundstage Australia Review

      Kurtis Blow - America
      US 1985 OG in sealed condition
      (Mercury - 422 826 141-1 M-1)
      NM/M   SEALED!!
      Small tears in shrink and top right corner has worn slightly. hype sticker, and small remnants of price stickers.
      OG killer album, wrapped perfectly in factory shrink.
      The album includes the song "If I Ruled the World" from the movie Krush Goove, Kurt's biggest hit since 'The Breaks' and one of the last of his musical career.  The album was released in an era when old school hip-hop was being overtaken by a harder sound and attitude, but the album nevertheless spawned Kurt's biggest UK hit single, with "If I Ruled the World", which reached number 24 in the UK Singles Chart in January 1986.
      This album also includes the first sample loop which revolutionized the music industry.
      Rare to find in this condition.
      Mastered by Herbie Powers Jr - not available (never!) on CD.

              Any title here gets a brand new inner and/or outer quality Blake sleeve as needed before shipping.

             I fully guarantee everything I offer  - if you don't like any item for whatever reason, return it at my expense for a full refund, no questions asked (verified 30 day+ active Forum members only thanks)..
             Original contents are stored inside the cover.
      I try to ship all records themselves outside the cover, so any postal damage is minimised.
             I use mostly s/hand pre-made cardboard mailers for all orders, and these virtually guarantee safe arrival of your record (they are also MUCH faster to pack).
             Combined postage to anywhere in Australia at cost (or close enough) and is EXTRA (ie. not included in prices). 
            ABSOLUTELY NO LOCAL PICKUPS - don't ask - it's not going to happen.
