Class A or AB Solid State Integrated Amp for Spendor D9's - Coming from Tubes

So I'm looking at getting a solid state Class A or AB integrated amp to go with my Spendor D9's and my Lumin T2. I strictly stream and do not have a turntable setup. I'm coming from my Line Magnetic 805ia which I love (will still keep it around but turn it on for those times where I want to listen to tube and not drain its life on watching TV) but I would still like to find a warmer/sweeter sound rather than a sterile, ultra-analytical sound. Some that I have considered include: 

• Luxman 590AXII
• Accuphase E800
• Diablo 300
• Boulder 866

I have not heard the Diablo or the Boulder in person because there aren't any dealers in the WA area but I hear great things. Any thoughts or help would be much appreciated! 

Thanks!
