Help with speaker cables and interconnects

My system comprises a TAG Mclaren CDT20R Transport linked to TAG's DPA32R Pre/Dac. This feeds a pair of Audiolab 8000MX monoblocks, which are wire to Monitor Audio 20SE's. Current wiring is LAT interconnects and Audioquest Indigo + speaker cable. The sound is very clean, but somewhat cold and lacking in weight. The Audiolab/Monitor Audio had plenty of power when used witha marantz cd63KI signature Cd player, but this appears to be lacking with the TAG gear. I have tried using Nordost Valhalla digital between CD & DAC and Valkyrja between pre and power amps. This gives amazing detail, but again lacks the warmth. Any advice would be very welcome. Muz.
