mmm, If you wanna compare it to a Brax, helix, ADS, PPI, Xtant, JL, RF, Orion etc... it cant cut it.
If you want to compare it with Audiobank, Rogers, Debetz, Sony then its ok.
The price for an Epsilon is about 900+ for the 4x75W amp if I remember correctly which IMHO, a PPI or ADS amp (Which is about RM1000) will give better SQ. For sub duty however, the Epsilon will beat the ADS and PPI due to power.
