What’s in your system today that you also had 10 years ago?

Linn LP12 with SME 3009ii improved; Shure V15 iii replaced by M97XE (but hardly ever used anymore).

At the time I had a Marantz multiformat DVD/SACD player, since replaced by a Panasonic Bluray/multiformat player that I will replace by an Oppo 4k player as soon as there is a meaningful amount of 4K material.

Quad 33 pre amp (refurbished).

The Quad 303 was replaced by a Quad 606-2 and the Quad ELS 57 speakers were replaced by their 2805. In short, the replacements were in the same style. More recently I added a subwoofer plus Antimode 8033.

VPI HW-19 MK3 with SME 309 tonearm and Grado TLZ cartridge ( new stylus replacement just about every two years).

Linn Genki CD player

I have my London/Decca Super Gold cartridge since the 80s. It's been serviced and had the stylus replaced with a better one. Incredible device. I've also kept my LP12 around but it needs repairs. 

SOTA Sapphire turntable.
Magnepan Unitrac tonearm.
Stax Lambda Pro headphones (but with a different Stax amplifier).
REL (Radio Engineering Laboratories) Precedent FM tuner.
Tandberg 3004 cassette deck.
