How can I further improve the sound of my Copland with the right tubes?
With Copland, a carefully selected tube configuration can often bring out even more sound quality. This applies, for example, to models such as CTA407, CTA408, CTA405A, CTA402, CTA506, CTA305 or CTA301. Instead of simply using standard tubes, the sound can be specifically improved with selected Genalex or hand-selected S4A tubes toward more quietness, fine detail and musical naturalness. It is always important to choose the tubes to match the respective unit and the desired tonal tuning.
