I'd recommend adding a "TWL mod" to your 250, at the expense of sounding like I'm beating my own drum.
Please check out the "Strange Tonearm Tweak" thread, here in the Analog forum.
Many have found this to be a very solid improvement, particularly with the lower compliance cartridges, such as your Koetsu. In fact, it would be perfect for matching your Koetsu to that arm.
Note that I no longer sell this mod, and it is easy to DIY for about a couple of dollars.
You can make it removable if you want(by using Blu-Tack as the adhesive), so you can do a "before and after" comparison, and remove it if you don't like it.
If you don't think it is a dramatic improvement, I would be quite surprised, as many others have called it "the best mod for the money, ever".
It wouldn't surprise me to find that it makes more improvement than all your previous mods.
It has found many happy users, all over the world, and on this site, and on AA.
Maybe when you start hearing more of what your Koetsu can do, you might not want to change it. And that could save you bags of money.
