I upgraded from the Linear Tube Audio (LTA) MZ2 to the MZ3 and it was quite an improvement. Based upon recommended NOS tubes from Brent Jessee, the MZ3 provides tonality that really fits my requirements. The MZ3 drives either a tube LTA Ultralinear or upgraded solid-state SMc DNA-1.
Good luck on finding equipment that provides your tonality requirement!
