If you love high end music, you need a good power amp. But if you like to be everything pronounced and well etched then you have got to check out the six feet tall and half a ton heavy monster designed by Pivetta Andrea, called as the Pivetta Opera One. The amp has been built by the Italian company in his own name and will be distributed worldwide by HigherFi exclusively. The Opera One can also be attached to a surround system that has up to 12 speakers. Priced at $650,000, the Pivetta Opera One is available at a discounted price of $490,000 from HigherFi, and can be paid for in installments.
