Hi Alistair, welcome to AoS.
My first thought speaker-wise after reading your opening post was Wharfedale Super-Linton, and that was before I'd seen Macca's reply! Might well give you just the sound you're after.
As for amplifier, well, this is one I've been considering as it looks like such a bargain, even though I don't actually need another amp...

They even do a matching CD player (though there will be other possibly better models at around that price). I know you said you no longer have any CDs, but it wouldn't cost much to get going on a collection.
