Hi, What solid state pre-amps go good with the Krell KST-100 power amp? My father (Tim) is selling his Conrad Johnson Premier 14 valve pre-amp. Because it is not suitable with his KST-100. the conrad P14 made the Krell sound very boaring and fatigue. For the last 2 days we have been using my Rotel RC-03 pre-amp on the Krell. Well what can we say, WHAT A HUGE IMPROVEMENT!!!!!!!!! The sound has opened up, better midrange, dynamics and bass. But the Krell needs a better solid state pre-amp though. Don't get me wrong about the Rotel. It's a grate entry level pre. Any help please. Shane
