AUDIO RESEARCH REFERENCE 300 MKII amplifiers upgraded sockets, Billy Bag Stands. Arguably one of the finest tube amplifiers. A Jonathan Valin favorite. Will be sorely missed, but must downsize the system at this time. Had the newest tube sockets installed at AR at the last retubing about 1200 hrs ago. Same design and sound as the Ref. 600MKIII according to AR. Best value for power and sound. Original shipping boxes. Must go by truck as they are about 220lbs each boxed.
典范的建立，经常需要时间酝酿，对于Audio Research而言，从1970年创立至今，36个年头只为钻研 (High Definition)的最高境界。创办者Willaim Z. Johonson已经年逾80同仍然亲身参与重要的研发 工作。虽然真空管并不是品牌制作音响的唯一素材，但是过往的经典产品以及最新的全系列Reference 器材，全部是真空管机。
