I did read up on the RLD-1 and many people described it as having a "tubey" sound, or being particularly well-suited to pairing with a tube amp, so I didn't think it would be my thing (I prefer a very neutral sound). The RLD-1 is certainly a well-regarded piece of gear though, and was solidly in my price range. If I was looking for a little warmth in my system it probably would have been my choice.
