No experience with the Decware but I have a Sachs mod SP-14. Don can install appropriate caps to match the input for just about any amp. Mine is set to match tube or most SS amps, unless unusually low impedance. Also I find the cherry cabinet very good looking, but personal taste can vary. Sonics are outstanding.
