I have the Marantz SA7001-KI CDP and can heartily recommend it. I'd imagine that the Pearl Lite SACD player would continue the trend for the company's players, however, I've no idea about the amp. Of course, if it's SACD functionality you're after, there are alternatives that will offer more formats (DVD-A, HDCD and hi-res audio) in the shape of Cambridge's BD651 or the outgoing BD650.
You could also quite reasonably take a look at Sony's Blu-Ray players, most of which also offer SACD functionality (it's their baby after all). The downside to those is the slightly fiddly transports (I used to have the BDP-S370) but sound quality is not an issue.
For straight SQ though, the Marantz source gear is excellent for the money and of course, the PL has additional DAC options too. I probably wouldn't pick one now (I'd look to use other means to widen the digital replay options) but they are well specced and well built too.
