K&J will we see a hf2 in the collection soon?
I don't think so. @wormsdriver was at a great, Black Friday, never-to-be-seen-again price. At the going rate, which is about 50% higher, it is lower on my list of headphone acquisitions than, say, the top of line Grado IEMs, that is, the GR10e (which I JUST ordered from Overture Audio for my own Christmas present!).
I actually have some method to what might seem binge Grado buying. I rank possibilities on three criteria... Performance (best of class, middle of road, or less than average), "diversity" (is it just another variation of a Grado model I have, e.g., SR325is, or is it way different, like a Grado IEM), and "rapport" (how much do I want it and how much do I identify with the product or company (alway top score of 3 with Grado!).
I then divide the total score by the cost of the item to get a "Satisfaction Efficiency" (yep, I'm an engineer).
List at the moment:
1) Upgrade my Schiit BiFrost Uber USB2 to the Multibit option (ordered, not yet received)
2) GR10e IEMs (ordered, not yet received)
3) RS2 with buttons, original type (HHAARRDD to find in good condition... rarer than vintage buttoned RS1)
4) Oppo HA-2 portable headphone amp/DAC for iPhone
5) HF-2
Others lower on the list include the Grado PS1000e, GS1000i, the Chord Mojo, the Chord Hugo, and the Shure SE846 IEMs.
