Opinions,everybody has them. However, the only opinion that matters is mine! ;>D
Like all "simple" 'X7 setups, the "Chrome Cutie" can't fight its way out of a wet paper bag.
The debate of active vs. passive EQ will never end. A clear thing is that passive topology is more overload resistant. Active EQ makes changing between RIAA (phono) and NAB (tape) easier. Fisher did the same thing in a GE style 6SC7 based unit.
Squeezing the max. possible out of a stock "Chrome Cutie" requires genuine 7025 equivalents, like the Sovtek 12AX7LPS. AC heating is employed.
IMO, an obvious tweak is full wave bridge rectification of the B+ supply using modern quiet diodes.
BTW, opamp phono preamps can be good. See Jim Hagerman's "Bugle". I agree with 'shovel that the hybrid baloney should be passed by.
