Point taken... For example: we placed a Wadia 830 on the ground (laminate wooden floor on concrete) and it became worse when we placed plywood under the player, whereas under the Lavardin it was much better...

Thanks! Still experimenting with a digital front-end. Have not heard anything better in my system than the TL-2x+NON OS Dac, but would love to have more control and rhythm, but still having the nice tonal balance and naturalness of the Ack dAck. Going to try the Copland CDA823 next, but would love to try a 2nd hand Wadia 860 and Marantz CD7 as well...
