What to upgrade first


Hello everyone I'm slowly workin on improving my system and would like suggestion on what to upgrade first and in what order I'm buying one item budget is 2500.

Current system is
Vac vintage line stage mkii
Audio rogue m-150
Technics sl-23 Tt with Orto os 10 cart
Nad pp1 phono
Mag span mg-1
Component cables RCA $4.99
128x128beep23
Thanks everyone for your help I have decide to upgrade one item at a time I'm gonna start with turntable maybe linn
There is a couple of nice demo under full warranty Marantz tables with cartridge for sale here at what I would call a good price (below $1000 and you can make an offer, 2 days left on the listings - not affiliated). I wish they made a black plinth on this table. Has gotten very good reviews and comes with a Grado Red cartridge.

I've heard Linns and they do sound very good when setup well and tweaked / upgraded, but they can be tough to setup yourself and it is recommended that they are only setup at home.

I think the Marantz, Mogami interconnect and speaker cables I mentioned plus a nice phono preamp would run you south of $2000 (about $800 for phono preamp, not sure which one at that level). Again, I really like the Pro-ject tube phono box II and that would put you about $1600 total and would leave you $900 for upgrading speakers if you want to go that route...
