budget amp for Apogee Duetta2's?

I had auditioned the Duetta II extensively back in its heydey in the late eighties. The Duettas are balanced very much on the warm side (but conversely can be strident in the upper mids and highs) and like being paired with an amplifier that is very dynamic, clean top end, and with high power. I wouldn't pair it with an amp that is inherently on the warm side. The Duetta can be ponderous and bass heavy with the wrong setup! The Duetta is a nominal 4 ohm load and demands a very good high current amp. The Classe'25 would be a very good match as would the Aragon. I heard the Duetta 2 with the Aragon 4004 and it was very nice. The 8008BB should work very well as it is an even more powerful version of the 4004. I thought the Threshold amps (S300 or preferably S500) of that period were also very good with the Apogee. Also agree that early Classe' designs (DR3,DR8,& DR9) would also work well because of their high current design. Personally, I preferred the Apogees with Threshold over Classe'. The Classe' amps are very 3D with a great soundstage and great musical texture. The Thresholds were livelier and more dynamic.
