Goldpoint Passive Preamps

I'm trying out some passive preamps and was wondering if anyone has tried the Goldpoint products. If so, which model, which attenuator, and which resistor. I'd also like to know what equipment you are using it with.

My equipment:

Transistor Research Labs D-225 solid state amp, 225 watts/per chammel, 67k ohm input impedance, .8V input sensitivity, 30db gain.

Spendor 1/2e speakers, 8 ohms, 88db sensitivity.

TRL Sony DVP-NS900V CDP, 2V output.

TRL Audio Mirror D1 Signature DAC, 1.5 output

Thanks in advance for your help.
