When you say “high end”, I unsure exactly what level you are looking at. The best unit I am aware of is the AVM PA8.3 preamp. You customize the design by choosing the cards you want included and it has both tube as SS output choices and tone controls. Most configurations put it in the $20k to $25k range and it is quite fairly priced in terms of what it delivers from a sound quality perspective. You would find it competitive with VAC or other preamps in that price range in terms of quality.
full disclosure, I am an AVM dealer. Not just trying to shill my products. As you can see, the list of products with tone controls is not long.
