Best integrated/power amplifier under $6000

Looking for either a power amp or integrated amplifier with at least 150 watts in 8 ohms for under $6000- new or slightly used. What would you recommend? I would be using my own DAC with volume control - so just need either a power amp or intergrated without a DAC. Please share your recommendations for the best amp you have heard which meets the above requirements. 

Thank you
