Anyone heard of Silence amp?

[Jaspok]

Hi guys, I'm looking at this used set of Silence S-4130 4 x 150w rms amp supposedly to be a Japan made amp. Anybody know if it's a good buy for my system below?

 

 

 

Front: German Maestro CS6508IV

Sub: Old MTX road thunder 12" sub in sealed box.

HU: JVC AVX-816

 

Currently using the HU to power the front Spkrs and considering other pre-own amps -

 

JVC 80w

Rodek 75w

Kicker 80w

JBL CS 65w

Audison Srx 4.

 

Appreciate any inputs.
