Universal tubes line level fully balanced input and output pure tube pre-amplifier

This is our newly designed series of pure tube pre-amplifiers which integrate both small and medium size tubes together in one single unit. Small size tubes (12AX7/12AU7/12AT7) will give you tighter bass punch, medium size tubes (6SL7/6SN7/6SU7) will give you a more natural and opened sound stage and tonal balance. By marrying these two type of tubes together, you will get the best performance in every aspect, which small tube pre or medium tube pre can't compete with.
