I know this is old thread but... Are K1xe and K3 have adjustable gain and plenty of it, you just need to get different values for internal resistors, they can be easily found inside of the unit
Ayre K-1xe vs Audio Research Ref 3
I currently have a Audio Research Ref 3 and am wondering if anyone has directly compared the Ref 3 to the Ayre K-1xe. What were the strengths and weaknesses of each? Which was better? I have read the other posts on audiogon and am looking for some additional comments.
