Hi,
Below are the specs. I would encourage anyone to google the many reviews, both professional and consumer, available on the internet. This is a very high performing pre. I have owned it prior.
STP Specifications:

<0.003% THD+N
Noise (A-weighted / VOL ≤ 63)
< 6 µV
Noise (A-weighted / VOL ≥ 64)
< 18 µV
Noise (20-20kHz / VOL ≤ 63)
< 9 µV
Noise (20-20kHz / VOL ≥ 64)
< 27 µV
Frequency Response
(20-20kHz / 2V)
+/- 0.02 db
Channel Tracking (All Steps)
< +/- 0.05 db
IMD
< 0.002%
Crosstalk (20-20kHz / VOL ≤ 63)
>106 db
Crosstalk (20-20kHz / VOL ≥ 64)
> 96 db
Output Impedance (VOL ≤ 63)
113 Ω
Output Impedance (VOL ≥ 64)
78 Ω
Input Impedance
60.4kΩ
Maximum Output Voltage
9V RMS
*Vol ≤ 63 (gain stage not engaged)
*Vol ≥ 64 (gain stage engaged)
