The Celeste PW-3000ES is the best 800$ Can integrate amplifier that I heard. This is a big amplifier in a small box. This integrate amplifier is powerfull and strong. If you listen orchestra, rock music, etc... we will like it. It give lot of details. The sounstage is deep and wide. It transmit everything. Also, it can drive easly 4 ohm speakers (my speaker are 6ohm Mirage 990 speaker). This amplifier is honor the Sima reputation, fast sound, strong sound, detail sound. Bravo!
