SP-331MK

powerLine

Hybrid class-A stereo power amplifier

Elegant, timeless, clean technology, perfection for a power amplifier. Here, valves creating the typical sound that is amplified in the power section by the transistors. In addition, the voltage stabilisation works with a 6N10 valve and thereby provides a trouble-free 10W Class A operation. The secret tip.

SP-331

Hybrid stereo power amplifier

A partner for our SA-31 preamplifier resulting from straightforward development, it profits from valve and transistor know-how.

SP-994

Class-A Stereo Power Amplifier

Reissued remastered stereo amplifier with power supply, which gives the amp more musicality.

SP-995

Class-A mono power amplifier

With its input switch and Class A operation that can be turned off, an improved solidLine successor to the SP-991.

SP-997

Mono power amplifier

Main amplifier for one channel, combinable in various systems, with more power reserves than the SP-996.

SP-998

Mono power amplifier

These tough guys have no problem with any loudspeakers and they play especially well with the SA-94.

SP-T700

Class-A mono Tube power amplifier

Many have already lost their hearts to these little monoblocks that have been tried and tested in particular with the SA-T7.
