The Lector Zoe is quite the preamplifier ,it has loads of headroom and it is miles better than the good T.A.S review done over 4 years ago now a mk-3 ,and being able to use 6 different tubes types let's you taylor the pre exactly to your ear.
70s 6h-30 Russian tube is a great tube for this excellent preamp.I have found No preamp in the $5k range that truly
betters this preamp in more than one dept,and I have tried several big named preamps ,one of the best buys in all of audio amd this also goes for their great
cd-7-Mk-3 player.
