There certainly are many routes. Is it worth experimenting with LISST when there's Magni 2 uber? Jotty is a fine piece of kit. If you don't want the hobby of rolling tubes Jotty comes close to Mjolnir 2, less money and no tubes. If you branch out into speakers it's a fine preamp (no remote) and if you like it you have the option of two Vidars and the headroom that brings. Want a turntable? Just add the phono stage.
If you eventually go all balanced right through to your cans and do speakers you may save time and frustration chasing down ground loops. But then if you still like your Vali (you can use the single ended out of a Gumby for instance) you will probably end up leaving an adapter for single ended plugged in for convenience and now you're spending more money.
So part of it might be a realistic budget. Good thing this Schiit is affordable!
