Shoot out between 2 preamps

I have an Adcom 750 and an older Tandberg 3018A. The Tandberg seems to be sweeter and more laid back. The Adcom has more detail but is crisper and brighter. That I dont need. I have a Bryston 4BSST amp with a modified Shanling T200 SACD player. Kimber KCAG silver cables and Transparent Audio speaker cables. Does anyone know the sonic characteristics of these 2 preamps? Did I describe them right. I dont claim to have a golden ear. Could the Tanberg be overall better? In 1988 dollars the Tandberg went for around $2000. In 2005 dollars that should be close to $3000. About twice of what the Adcom sells for. Does anyone else think the Adcom is strident? Any input would be appreciated. Thanks
