I had very early models of Dusty's phono preamp and DAC for many years, and when it came time to upgrade the phono preamp, I returned for the PEQ-1 MkII, despite a ton of available competition at its $1K pricepoint. As others have said, it's a great, straightforward company, and they put their all into their products, combining solid engineering and (I believe) listening, too. I get very neutral, detailed and lifelike sound from them.
