Soft, smooth organic SS integrated amps?

Aside from the Sugden A21 series, what other more "budget" solid state amps (under $2K new or used) in your experience with at least 25 wpc manufactured within 20 years offer a really smooth, organic sound? I don't want to go the tubes route again. I'm thinking Heed, Arcam (at least the older, pre class G era)? What else in your experience?
