What to upgrade first

Thanks everyone for your suggestions I do like the sound of manepan speakers and when I upgrade it will be to 1.7 or 3.5 Or 3.6.

Any other suggestions on phono pre and turntable that are good performance price ration also considering used equipment.

Does the upgrade From m-150 to m-180 make such an improvement in sound the upgrade is about $1495 when I checked.

Thanks everyone for your help I have decide to upgrade one item at a time I'm gonna start with turntable maybe linn
