SP-T700

tubeLine

Class-A mono Tube power amplifier

A completely new combination amplifier was developed for the SP-T700, exploiting the respective advantages of tubes and transistors in an innovative manner, combining them to create a harmonious whole. The SP-T700 is characterised by excellent reproduction features that remain constant over the entire frequency and load range and it has a superior power reserve.

The tubes are 100% selected frame grid tubes from the military sector. They are designed for a lifetime of 10,000 hours.

The best of two worlds: Subtle reproduction of voices and acoustic instruments, plus the strength and punch of a huge rock stage – the SP-T700 is an exceptional power amplifier that meets such contradictory requirements with elegant ease. This is only possible due to the latest tube technology, combined with a transistor end stage. The outcome: Inspiring sound, plus strength and comprehensive speaker control.
