Bluesound mode not really cutting it

Running a bluesound node. Sounds pretty good but I feel like I can do better. I'm running a Black ice Dac thru a Schiit saga plus into a Mac Mc 152 and Lsa signature 20's. Looking to upgrade node I have 2 to 3 k to spend. Hard to find decent reviews. Any suggestions. Listen to blues classic rock and anything that sounds good. Have tenants downstairs so listen at moderate levels and kinda prefer realistic or almost tube or liquid sound.
