hmm, here's what i can find about the peachtree's preamp:
Class A Preamp output stage
<30 Ohms output impedance
Hybrid tube design using triode (Stereo 6N1P)
6.5V output @ 2.0V input
2V input so should be ideal?
one other thing, i notice a slight high pitched whining from time to time... normal?
anyway, heres a pic of my newly acquired ms-20l, powering zu essence, sounds great so far, well worth the price i paid
