I'm still using a very old system.......
Linn LP!2 turntable, with the usual Ittok arm and Asak cartridge
Naim CDS
Meridian 101 and 105 Amplifiers
Isobarik Speakers
It may be ancient but it still sounds good. The youngest item, the Naim CD player, needs attention but Naim will not repair them, only offer a trade-in on the current model.
The oldest part of the set-up are the Meridian amps, bought them around 1978 whilst still a teenager - still working well.
I sometimes wonder about updating parts of the system, then I look at the prices and go off the idea, but the CDS will have to be repaired or replaced sooner or later.
