Hi there, to my ears and in my system. Going from Dac to amp sounds exactly the as same going dac to preamp to amp. Its very likely the MH- DA006 was voiced and designed from the success from the preeamp. Having said that I usually run the Dac directly feeding the amplifier as their is no sonic difference. I use the preeamp in a secondary system . It is very Balanced, the soundstage is puts everything in line not emphasizing on one or the other. Im certain the 006 amplifier section is identical to the preamp. Im keeping both.
