Following on from this...
Covid ruined real chances to go out and listen to replacement speakers, but the few shops I did visit actually really let me down in terms of customer service and just letting me listen to some systems. One put me on the shop floor then told me to not turn it up too much.. ok m9.
So eBay to the rescue - I decided to find look for Dali's of similar vintage to mine in attempt to get a matching centre speaker as a minimum. Well I haven't quite succeeded but I found a set of Dali Ikon MK1 speakers (centre + LR) from a guy doing an upgrade.
The centre is a little bit smaller than I had realised, and is a slightly different grey finish on the front. But thwe wood finishes match, so it still looks decent and sounds really good too.
The bookshelf speakers will find their way into my office and be powered by a Sonos amp but I gave them a chance via the Marantz in the living room for two films and I was pleasantly surprised at the bass response and general sound quality. So much so that it had me rethinking floor standers in my living room... until I wanted more volume and the audio became a little bit more complex, then I remembered I'm very much a floor stander kinda guy
Anyway today I spent this afternoon routing some cabling (including running a couple of cable pullers so I can run a new HDMI to my projector to support 4K HDR at some point), mounting the TV on the wall and having a general tidy of my kit into a corner unit I got for free from a neighbour.
Aside from the centre looking a bit small, I'm really happy with how it looks now. Rears and Atmos next on the list, and if a larger centre comes up that matches - even better !
Thanks for looking
