I got a better sense of the speakers I wound up buying (Magneplanar 1.7s) when they were connected to an NAD C 375BEE 150wpc integrated amp. Even then, I would have preferred to play some vinyl I brought along but the turntable in the mid-fi room was some afterthought piece of crap, as was the phono stage it was plugged into. So I made do with hi-res digital sources.
Concerning the Goldenears, your experience matches the warnings I’ve read in a few reviews: the Tritons are so affordable they’re often paired up with mid-level A/V receivers while their high resolution and linearity demand at least an NAD integrated amp such as I heard, or better separates. GoldenEar Designer Sandy Gross uses a handmade SET amp for his Tritons at home.
