What to upgrade first

There was a Pro-ject tube phono box II in black for sale here a couple of days ago for $350. Not sure how you can track down the seller if it is still for sale. I really like mine, which sounds better than the Vincent Pho-8 and Musical Fidelity V-LPS.

I also really like my Pro-ject Xpression III TT with Ortofon MC-3 turbo cartridge. The RP3 and Traveler are getting very good reviews also.

For interconnects, you can get a big improvement for not much money. I could not believe the performance of my Mogami cables that Pro Audio LA built for me (not affiliated) for $24 a 3 foot pair at Pro Audio LA - Mogami 2549. I had them float the ground on one end to make them "shotgun" directional. I also use Mogami's speaker wire (see my system page).

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...
