Your Deccaware Tori has
- INPUT IMPEDANCE: 100 K OHMS
- INPUT SENSITIVITY: FULL POWER @ 2.0 VOLTS
If you use a passive/tvc type pre, then your source should be able to have over 2v output and have less than 1kohm output impedance.
Suggest a passive pre that has the option of active tube or solid state switchability with some gain. The Schiit Freya is right up your alley. This way you can have three different ways of driving the Tori.
