I mean, I'm not criticizing such prices, it's nice to have a direct replacement if you can afford such investment. Also, I understand design and production of such implies costs beyond my knowledge and they have a limited market to make it profitable. Just to make clear, I'm not saying those amps are overpriced, I'm just saying I can't afford one.
So, did anyone try such DIY alternatives? I know about the "free wurli" project, but it's from years ago. Build cost estimation was 120€ then, I think nowadays we could do it cheaper, I could be wrong though.
