I'm considering an in-wall centre speaker and have been looking at a few. The ones that caught my eye are the Linn diskreets which seem great value at £200 a pair. I'm replacing a Ruark Dialogue R so want something that does the business. I listen to a lot of DVD-A/ SACD stuff so it has to be capable. Am I going to lose quality with the Linn? Great name but seem cheap. I can use the other one as a centre back too which is appealing. Must be somebody out the used them. Are the sekrits better for my needs?
