I've tried both the Triode and Dynakits. They're both excellent. The Triode's have the PFE Teflon leads, but their power transformers's secondaries tended to run about 10% high.
Measurements: Bob Latino posted some distortion chart comparisons a few years back. The results were virtually identical with the Dynakit about .1% higher at 35 kHz. The differences wouldn't have been audible
