To my mind, there is only one answer: SUPRATK!! Either a Supratek CHENIN model tube preamp, at $2900 with phono stage, or the less expensive CHARDONEY, without phono stage, at $2100. These are world class preamps at VERY reasonable prices. They will definitely make your system sing. Both have the surround sound bypass feature that you'll need.
