I am a little confused here , please can someone shed some light? I am looking at buying the Yamaha HTR5640 from Richer Sounds (£198.95 on web site). However is there a HTR5640 and a HTR5640RDS, and is there any difference, or are they one in the same thing??? (Richer Sounds only state a HTR5640) Have a look at the following link and the links to the PDF brochure and Instructions:- http://www.superfi.co.uk/index.cfm/page/moreinfo.cfm/Product_ID/1437 This link is for a YAMAHA RXV440 / HTR5640RDS HOME CINEMA RECEIVER the RXV440 being black and the HTR5640RDS being silver, but both listed as £209.95 (reduced from £299.95). The details on this page say that both have 6 x 65W, however the brochure shows 110W (for the RXV440???) but Richer Sounds show 6x110W for the RXV440 and 6x75W for the HTR5640??? Also, Richer Sounds have the RXV440 at £219.95 (reduced from £399.95) and the HTR5640 at £198.95 (reduced from £299.95). Am I missing something , or is the above a bit confusing? If there are differences, please can anyone let me know before I take the plunge in buying one. Cheers.
