Eavr11, even though you already made your purchase decision, I wanted to weigh in here with another recommendation for others who may read this thread. I have used the Avalon Eidolons for nearly 5 years now, and have tried several amps with them, tube and solid state.
I recently decided to try a Class D amp to see what the fuss was all about. After reviewing the offerings in the market, I acquired a pair of the Gilmore Class D Raptor 500D's. These class D monoblock amps offer 500 watts per channel into 4 ohms, and they are priced at a very reasonable $5000 for the pair.
I was blown away by what these Gilmore Raptor amps could do with my Eidolons! They easily and substantially bettered the Parasound JC1's I used for over a year, which sell for $6000 a pair. Soundstaging, a great strength of the Eidolons, was even more fabulous with these amps. The level of detail that comes through is also incredible. I particularly enjoyed these amps with good rock recordings. I'm so impressed with these amps, I plan to write a review on them in the near future, but wanted to offer this recommendation now for those seeking a reasonably priced pair of solid state amps for their Eidolons.
