Lots of choices to consider.
I would suggest checking out the Thomas Mayer 10y Line Preamp. I think this is one of his best known products.
Each unit hand built to your specs by him personally. You can select for what combination of inputs and outputs, chassis wood and paint scheme, he may also give choices on input and output transformers. It can run 10y VT-25 tubes, 801a VT-62 or his own Elrog 801a tubes.
Also transformer volume control is standard which is very rare. The build quality and parts selection are at the highest level. If you are outside the EU you can deduct the 19% VAT from the price. To the US and without pricey options it would cost about $10k.
