So you say to yourself. What the FEEK!!! Or something like that. LOL
So here's the deal. Quimper think the only way to get a great tube sound without a tube is build one as the circuit itself.
The standard deal is to think ... FET or field effect transistor ...when pushed it sounds tube like. To simplify it creates a square wave with rounded corners ...with a real tube the whole wave is rounded wave. Close enough ???
Not for Quimper!
Well they did it. It is on one hand very impressive but on the other ...it is very subtle.
