Looking at a pair of QS Mid Mono tube amps
These are what Sam Tellig (Sterophile) has and loves (his favorite amp) and because they only need 1.2v input for full power output, they only needed my Lightspeed passive pre which he uses with them, as nearly all sources will have more than 1.2v output, cd is min 2v and even phono stages are over 1v
