Linn Ittok or Grace 707?


I am looking to upgrade from the Linn Basik LVX on an older model Sota Sapphire with suspended platter. Should I consider the Grace 707 (MKII) as a significant improvement or wait a while and get something like the Linn Ittok (LVII)? I'd likely get a new cartridge that matches whatever arm I chose.....but have a functional Monster Alpha on now.

Any thoughts would be appreciated.
Linn no longer supports the Ittok, so if you go that route and need service, you'll be out of luck

Thanks guys. I'd rather not make any changes that aren't significant improvements. Doesn't sound like the 707 is a major step up.
