Hi Rnik, could you describe more precisely what is missing? Do you have trouble with deep bass do you want more midrange fullness? I think one of the characteristics of the eAR 1001 is the capability to deliver abysmal bass. I can say this because I also own the eAR 1001. Only I wish it had more midrange fullness: the sound would have be close to perfect in my opinion. I spoke Peter by phone when I was experiencing difficulties with the amps. He called me at home after some email correspondence, something I didn't expect. What speakers do you have?
