Best integrated/power amplifier under $6000

Some people love Boulder others find the sound too sterile. May want to check out this unit.

Levinson 585  is an excellent integrated. Loved it demoing Magico A3's.

@dherring Your Hegel 590 is supposed to get ROON READY certification in late fall 2019. The new Hegel 390 integrated has ROON READY and this tech is supposed to be added to the 590. 

This was a big deal for me.

@audiolabyrinth  Interesting comments on the Luxman 509x. I auditioned this integrated recently with a Luxman DAC + TAD ME1 speakers and I would not categorize the sound I heard as you described. I switched over to the Luxman separates and it was significantly better than the 509x but the 509x was rather good.
 
Your Krell 300i is getting some love at the Munich show. I might need to have a listen to this new Krell XD designs before I lay down the dollars for the Luxman m900u amp I plan on buying.

@audiolabyrinth  Thanks for your feedback on the Krell vs Luxman. I have 12+ hours to kill in Los Angeles in the first week of June. You have now given me something worthwhile to do. I know where to hear the Luxman but need to find a Krell XD on demo somewhere.
