Please note I must respectfully disagree with Trelja and all who purport the Golds present SUCH a difficult load. I have owned the Gold i's for a year and a half and though not the easiest load, for what they ARE, I have found them to be a most forgiving speaker. The fact is, by merely employing a little bit of common sense in my choice of amps with which to experiment, I have yet to find an amp that has NOT made for a very DECENT match! Specifically, I have tried the Bryston 3B, 3BST, 4BST, McCormack DNA-1, Belles 150A, Andy Bartha modified Belles 150A, Belles 150A Hot Rod Edition and most recently, VAC Vintage 100 Mk II (VT 100 Mk II), read---*T U B E* monoblocks---which I happen to absolutely LOVE with the Golds! Moreover, I have found I prefer on most source material, running the VACs in their single-ended mode (57 wpc approx.) as opposed to the ultralinear mode (100 wpc approx.)! Further, after experiencing these rather startling results with the VACs, I am truly tempted to temporarily rewire my newly built Welborne Laurel 300B SET monoblocks for 4 Ohms, just to try them out with the Golds for the heck of seeing what they can do. Finally, the second best match up was with the Bartha modified Belles amp, followed closely by the Belles 150A Hot Rod. *Please note the Bartha modified amp and VACs are very rare to come across and that is why I opted to recommend solely the stock, readily available Belles Hot Rod in my first response in this thread. Again, for your reference, my listening room is 25x23x16.
