I'm new here, and I love the site. I'm interested in a non-ANC noise-canceling headphone, i.e. a closed headphone with really good isolation. Price: Under $150. Current equipment: Vintage AKG K141, Bose Triport (barf), Fiio E5, and Yamaha CA-810. These headphones will be plugged into the Fiio most of the time, as I'll be using them when most other people would use ANC headphones, i.e. in the car or on the plane. So, they'll be replacing my Triports. I realize that basically any headphone is better than the Triport, but I want the best value. I've been eyeing the Shure SRH840 but apparently they have awful isolation, so I'm resorting to asking for directions. Thanks in advance, guys.
P.S. I'm going to be buying a Nuforce uDAC-2 to use as a DAC and desktop headphone amp for the K141. Is this a good idea?
