What amp to use with Apogee Stage speakers

I can second Bobspeak in his recommendation of the Aragon 4004 MKII.

It's a great amp for these speakers. I used one in London for 8 years, never turned it off, and with the Stage's it was one of the best combinations I have ever had.

I would guess you would really need to spend some serious $$$ to do much better.

I'm using a Electrocompaniet AW100DMB and I'm very happy, this amplifier push the Stages on his limits.

I still use Stage speakers as my main speakers, although they have been rebuilt with Graz ribbons and I use active crossovers now. The best amp I tried with them when I had the passive crossover was the VTL Sig 450 monos, although I would imagine any of the VTL or Manley with at least 300w/channel would do just as well, tetrode mode is better. Less than 200 tube watts is iffy. I never liked them that much with any solid state amp including the Classe amps, although a Sunfire amp used in Current Source output mode should work very well. I like the Sunfire on my bass panels (325w/channel).

I agree the Aragon 4004MkII is a great amp for these. However I accidentally discovered that a 35 year old Yamaha CA-1010 gives the Stages the timbre and texture acoustic instruments deserve! At only 90W (8Ohm), 120W (4Ohm) can drive the Stages pretty loud (if the recording is compressed enough) and to a nice level in a lively room if it's a really good recording. The stereo imaging and detail is the best I've heard out of the Stages, and I've had my pair 20 years. I would say that you must be careful not to have too much power or you will end up rebuilding your ribbons. Keep it under 150W 4ohm with a high current amp.
The only other amp I've tried was my ARC D125 (115W). Sadly, this very transparent amp I'd didn't do anything for the potential these speakers possess.

as funny as it may seem but we tried a a/b test with a crown xls 2000 versus a pair of monoblocs classe cam-400 ,and the crown just blew the doors off the classe!!
i never heard a stage sound so lively, everything was absolutly controled,everything became transparent,no bomminess just the recording being reproduced at it's best. a 500$ amp matched better then a pair of 11000$ amps!
i bought the apogee stage ,outstanding speaker with this amp.oh and before you say:yeah but the crown has a fan,well yes but we didn't know it was running until i put my hand in the back and felt the air moving, it's completly silent.
