Look, I have minor quibbles with Trinity as well (not so much customer service as it is QC though), but I firmly believe that, given what Trinity offers for the money, I can't complain, and I think all you guys that come on Head-fi to complain at every little thing are a little spoiled. I may have had a issue or two, but I will sort it out privately with Trinity's Customer Service and keep it off of Head-fi unless there is a severely catastrophic failure to support their product.
Jake, specifically, sent out a replacement filter and ear tip to me in Canada when one of mine fell off and I lost it. At no charge! Doesn't that speak volumes to their commitment to their customers?
Especially given the gracious Head Fi discount which can often be combined with pre-order prices, and the rock bottom prices to begin with, Trinity has what I would say are some of the best bargains in the industry.
I say this as an owner of the Delta v2 and now as an owner of the PM4. These things really do sound like the Deltas on steroids. Soundstage is so good it's the first time I don't feel like I need to stick to my circumaural headphones for classical music. Far superior to my 1964 A6s, especially in the bass region. And for a fraction of the price.
