You need high quality solid states to drive big magnetics in EA. Being both physically superior(Esotar tweetor..) and well tuned in singing music, it tends to pay back as much as you invest in source and amplication. I recommand Spectral dma-150 or Pass monos.
I use the Bow Technologies Wazoo integrated amplifier for my Sonus Faber Electra Speakers. The unit sells for around $3,500, is very smooth, very musicial and I suggest you listen to it in your system. The Sonus Faber Musica Integrated amplifier is another unit I suggest you try.
Well,Mjang 9 you are wrong Electra Amtor II is not using Esotar tweeter which is one of the best and very expensive.. Electra AmtorII has cheap focal not more than $ 70 wholesale which make them very bad buy in US specially...$ 6500 retail that' nuts.....
To Duzykot: your wrong about the tweeter: it's a ScanSpeak although not the top of the line Revelator, by many considered the best tweeter in the world.
