Emotiva BasX TA-100 integrated or BasX PT-100 preamp sound quality

Anyone have any experience with the Emotiva BasX TA-100 integrated or BasX PT-100 preamp and in comparison to like priced as well as higher priced components.  Looking at musicality, dimensionality, etc.  Considering for second system or if good enough to build upon in 2 channel configuration with a separate amp.  But would really like to know just how good the integrated with its own amp section is for its price. Thanks.
