@fanofmsu Yes I use the ISO and DC Recovery. They elevate the performance notably with a blacker background, better detail retrieval and imaging/staging. Replacing the Wyred supplied USB and wall wart LPS with higher quality products is mandatory to achieve the performance I speak of. However, for transparency, even though I believe the 10th Anniversary one of the best under $5k DACs and competitive with DACs many times its price in the areas I mentioned in my previous post, I am making my final improvement for my retirement system and picking up a Mola Mola Tambaqui from GTT Audio tomorrow. The 10th Anniversary will be on the market soon. I am going for that extra level of detail retrieval, extra level of analog/tube-like sweetness, liquidity, imaging/staging the Tambaqui provides. It comes at a cost but I will not be making any more changes in retirement.
