Nitewulf,
Definitely check out the impedance ratio between the Shindo and the Mac. Some Mac amps are as low as 10K, some preamps can be over 1K, not a great ratio.
I like CJ's newer preamps. I know the CT-5's output imp is spec'd at 800 and their ACT and ART's are 500. I have them and use them with my Pass ss, SET's and even a Class T amp, every pairing gives me great results.
