Thanks for your help to all who contributed, just thought I would mention that since starting this thread I had purchased a sim p-5 preamp and have to say I am very much so content. I am hearing alot of detail the bass is full reaches the lower octaves horns come through in life like fashion, when listening to opera at times it sounds close to what it sounds like in the concert hall on vinyl that is of course, and it has a wonderful sound stage. I most highly recommend this 2 chassis preamp and think that for the money used it's a bargain. Also should mention that it is fully balanced.
