This is a very impressive amp, beautiful quality build and simple, functional, elegant design. A famous designer and leader in the Victorian arts and crafts movement had a couple of sayings, “Less is more” and “Do not have anything in your house unless you know it to be useful or believe it to be beautiful “. I believe your amp fits all those categories perfectly! You have produced an amplifier that sounds wonderfully detailed without a hint of harshness that clearly surpasses earlier amp I have and the xxxxxxx (another magnetic passive preamp) I have been comparing it to. Many thanks for the marvellous amp,
Best Wishes, Mark.
