A great way to get a remote preamp would be an "obsolete" Harman Kardon receiver - like a pro logic model. These - AVR20 - AVR80 - have preouts, and are very neutral stereo preamps, with many inputs. Just ignore the prologic aspect of it. They sell for between $100 - $200. The larger HK units - AVR70 and 80 - would have the minimum wattage you need - 70 wpc. This may be the unexpected all in one answer.
But, if you feel the need for another amp, a guarantted mellow sounding unit comes from the DENON POA series of the mid 80's. I highly recommend the POA1500 - 150 wpc - usually on EBAY for $200 - 300 range. That amp in combo with an HK preamp will give detailed, yet slightly warm music.
