The PSU for my Trends TA-10.1 has been acting up; the power cuts on the DC side of the transformer frequently, and I only have luck if I force the IEC cord in and hold it. So, I wrote Audio Magus about my problem, and I had a response five minutes later offering to send me a replacement transformer.
Hot damn, that’s impressive. Didn’t think service like that still existed. Gives me incentive to go there next time I want to blow a load of money on the next bigger and better thing.
So yeah, if you’re looking for Tripath-based amplifier, I have been very pleased with my initial purchase as well as the ongoing support.
