SP-331

powerLine

Hybrid stereo power amplifier

Proven technology. The SP-331 power amplifier processes the input signal via two 6N16 valves each. There are 12 TOSHIBA transistors provided for the power in each case. The SP-331 can also be operated at 2 Ohm without difficulties. This is ensured by a ring core transformer with over 1,000 watts and filtering of 80,000 μF. The result: pleasant sound and deep basses.

SP-331MK

Hybrid class-A stereo power amplifier

This redesign of our hybrid legend has almost grown out of its class thanksto the best components!

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.
