There are what’s called tube buffers. In my own audio exploration they provide a quality tube experience and a compelling value. I’ve written about how one compares to a well regarded OTL tube amp here:
If you go Asgard 3, you can pick up one of these buffers, a tube upgrade, rca splitters, and a rca switch. Then you have excellent tube and solid state sound on tap for less than the price of a Valhalla.
