supratek chardonnay with Pass x250


Since Pass X250 input impedance is rather low (especially unbalanced) i'm trying to carefully match it with a tube pre. I could not find the output impedance figure of the Chardonnay and wonder if someone can asist with it and also with thoughts on this match. Thanks

Have mine with the X150. Best combo I have found. I tried many other preamps with the Pass Labs. I like the Supratek best.
Output Z of the Chardonnay is 600 ohms! The same is true for the Syra and Chenin(I have one) as well. Your amp has 22K of input Z (unbalance). Should be fine IMO.
