Signat Rom 4 High End German Audiophile Amp 4 x 125rms!

Up for grabs is an amp that sounds as good as it looks, the Signat Rom 4. German engineering with very high end components, excellent controls, and some very unique, extremely nice circuits total one killer sounding audiophile grade amp!

ROM amplifiers boast outstanding equipment and fascinating techniques! These SIGNAT amps completely stand out from the average and not just because of their exclusive physical appearance. Their output power and well-considered features are very seductive too; adjustable active crossovers allow for an optimized adaption to your loudspeaker system, steep subsonic filters avoid unnecessary strain.

 The three- and five channel ROM models feature 2 Ohm stable subwoofer (mono) channels. Optionally a SIGNAT BRC bass controlled can be installed.

 Naturally all ROM Amplifier come with SIGNAT BIC (balanced input circuity) inputs and the proven ENS (electronic noise suppression) system in order to guarantee the utmost reduction of unwanted noises.

The sound quality of the Rom 4 is really quite impressive. I was actually surprised at just how clean it was. The balanced input circuitry has a lot to do with that I think. Crisp high end but not harsh. Well defined midrange, and nice tight bass on the low end....and plenty of power. Actually, with the unregulated power supply, expect to see right at 120 wrms x 4 in a standard automobile enviroment.

I took the liberty of taking a peek inside...very nice. Twin power supplies, very high grade caps, wire wound resisters to the output fets, top shelf components in the signal path. A very nicely layed out and built amplifier. Not many of these hit Ebay so take the opportunity to pick one up at a very reasonable price!
