bernal737 don't guess, try a great class D amp. Orchard Audio is running an amp tour. Join the list on their website. Listen 7 days and and pay shipping to next person on the list. Then post a small review. After doing this I bought an Orchard Audio v1.0 StarKrimson Stereo Ultra DMC amp. The amp uses Orchard Audio's proprietary ganfet modules.
Thanks,
