The Woo WA5… without question. I put top quality 300B tubes in it and it is simply stunning. Not small or cheap. I also have a WA6 and WA6SE… they are great, but do not have the power to tame headphones like the Sennheiser 800. The WA5 just took control of every one of my headphones and made them sound musical, detailed, natural, and simply the best they could. Small… no, not small.
I have found that what you pay for from Woo is worth it. Read their descriptions… you can completely trust them. Call them. They will be happy to talk to you about what you want and the headphones you use… and honestly recommend what will be best for you. I can’t more highly recommend a company. I have owned at least a dozen headphone amps. I would not consider any other company.
