Addendum: The 3.6 and 3.7 impedance curves are practically identical.
John Siau at Benchmark modeled load tests on varous Thiel models including the 5i and 3.6 ( I don't have 3.7s). He allowed with caution bridged AHB2s for all the products except the 3.6. He predicted current delivery distress for the 3.6 / and therefore the 3.7.
It's a jungle.
Cheers,
Tom
