I am using a Graham 2.2T with my Oracle V.
From reviews I have perused, it seems that SME may not be the best choice for Oracle in spite of Oracle's commitment to SME. Fremer preferred the sound with the Graham several years ago, more recently Dudley preferred the Abis. (I have not directly compared). The Graham replaced the Alphason I had used on my Oracle I/II and is a big improvement.
