Micrex R1 Valve Preamp

Thanks for the link Mofi
Any owners here that have experience with the R1 ?
Supratek have a good reputation and was looking
for some owners views on the performance of the R1.

Cheers.

Ok fellas this is the specs on the Micrex R1 valve Preamp

SPECIFICATIONS
Output Impedance: <2K Ohms
Distortion: <-0.01% (1Vpp)
Frequency Response: 10Hz-100kHz (-3dB)
Hum & Noise: <-86dB unweighted
Stability: Unconditional

And this is the spec for the Redgum Audio power amp i have at this time which i wish to mate with the Micrex R1 valve preamp.

RG120ENRm - 155+ 155 Watt/Ch RMS (293 + 293 W RMS - transient)
Harmonic Distortion: less than .009% (below Clipping)
Intermodulation Distortion: less than .005% (below Clipping)
Signal to noise: greater than 100dB
Input Impedance: 10K ohms (matches 600 ohms - 50K ohms)
Slew Rate: greater than 65Volt / microsecond
Damping Factor >800
Frequency Response: 0.8 Hz to 80KHz (-3dB points)
Peak Current: greater than 120 amps.

I have little understanding of how impedence calculations are made and looking at the Micrex R1 preamp and the specs on the Redgum Audio power amp , would they be a synergistic match ?.
any technical minded members able to advise.

Cheers Phil.
