@ Iblieve, what do you mean? Krell has never made any mono blocks in that price range!, the most exspensive krell amps was the krell master referance mono blocks that are discontinued because of their price, $150,000.00 full retail,they weighed over 300 pounds each, that amp was a mid 90s to around 2003 or 2005. the new krell top amps do not even sound remotly as good as those mra amps or the krell kas top model two box amp from 1995!, LOL!, half the new amps do not sound as good as my Krell amp!you can get certain used model krells that will perform to the mc-811 or better for cheap, LOL!, not in the excess of over some $7,500.00!! new is not always better, no matter the brand, I can assure you that,, cheers and Happy listening to you Iblieve.
