I have some rather ancient Onkyo surround speakers. One of these has stopped working and I've noticed a horrible metallic distortion to the sound. These speakers were part of a "Cinema pack" which means they have to be 12yrs old, if not older. I enjoy having 5.1 surround sound, but I am not looking to spend a fortune on replacing these speakers/sub etc - let us say around £600 maximum, less if I can. Yamaha RX-V581 is staying. I'm happy with this receiver despite the lack of Dolby Vision support. It does pass HDR and I'm very happy with this. I am limited on space for the rear speakers - 210 x 160 x 150 (H x W x D) After reading through a number of posts I felt I'd maybe got down to a choice of three, which everyone here will be familiar with: Monitor Audio Mass 5.1 (Original version). Seems to get good reviews, being replaced so maybe able to get good pricing, however seems to go for around £499 Monitor Audio Mass 5.1 (2019 version). I notice that the centre speaker is just another satellite. Every other set of speakers I've looked at, the centre is different, offers more. I'm assuming MA know what they are doing on this front. Limited reviews available, but seems to be a good choice. Priced at £599, top of budget. Wharfedale DX-2 Seems to be the "go to" budget speaker set. Will never set the world alight, but offers good performance and sound quality for something sub £500. Seems to go for around the £349 mark. Is there any reason to go for any one of these over the others? Are there any other packages that are within budget that I should be taking a look at, taking my rather limited amount of space for the rear speakers into account? Cheers all.
