I'm not sure at this stage.
My turntable and streamer are fixed for as far ahead as I can see, as I have no issues with the performance of either and in both cases I don't think I could improve on them without spending a fortune I don't have.
It is also unlikely that I'll buy any more speakers in the forseeable future. I currently have Dali Oberon 5s, MA Bronze 200s, Wharfedale Linton 85s and Dynaudio DM2/6 plus the Spektor 2s on my upstairs system and some pairs of older speakers. I haven't got space for anymore, and that's a pretty decent selection to choose from.
What I haven't quite got right yet is the CD player and amplifier, and I'm considering my next purchase with extreme care. I've been through a huge number of amplifiers in the last 15 years. When I think about it, it's ridiculous. I should be settling down with something now and for a considerable length of time.
I want to establish a system I can be happy with for at least the next decade and that's going to take some thinking and a change of mindset. The amps I've enjoyed the most are the Arcam A65+, Naim Nait 3, Creek 4330R, Rega Brio-R, Exposure 1010 and Cambridge Audio Azur 740A- not necessarily the most expensive I've had, but certainly the most musically enjoyable.
The most satisfying CD players I've had (saving you the pain of a full list) are the Rega Apollo-R, Rotel RCD965BX (which I still have), Roksan Kandy K3, Arcam CD73T, Cambridge Audio Azur 740C, and Harman Kardon HD970.
So, what next, bearing in mind that I like long listening sessions and listen to a vast range of music?
One thought is simply to go back to entry-level Rega, in the form of Brio and Apollo. I enjoyed my Brio-R more than I did the Elex-R I had, and I think the Apollo is almost impossible to beat anywhere near its price.
My amp shortlist is as follows:
Naim Nait 5si
Exposure XM5
Arcam SA20
Creek Evolution 50A
My CD player shortlist is:
Naim CD-5si
Exposure XM5
Arcam CD-S50
Rega Apollo
or sticking with the Roksan I still have (though it doesn't like CDs that are longer than the 80 minute limit of the red book standard, and I have a good few of those in big classical box sets. Roksan has confirmed that this is normal as they use a dedicated audio drive that is designed to give its best with red book CDs).
