I had the HP-P1 and I'm pretty certain that the SOLO is much thinner, in terms of length it's, I think, either smaller or barely the same size but I'm not 100% on the length since I don't have the HP-P1 anymore. Sound-wise the CLAS is way better than the Fostex.
You're welcome to purchase it from Apple then...
That price is without taxes and it doesn't include the lighting adapter to use it with the old cable (for iDevice DACs like CLAS, and HP-P1) that is $39 and neither it includes the Smart Cover which is $39 plus tax.
Up for sale is in mint condition iPad Mini 64Gb (Black). Comes in its original box with all accessories including the lighting to 30 pin adapter. A red smart cover is also included. Will post pics later.
Ehh.. What's really the point of this? We know you like Heir Audio and all that but oftentimes fandom blinds the perception. I've had absolutely stellar customer service with my current CIEMS company. Last week one of the cable pins got broke and left in the sockets, this company not only repaired them in 3 days for free, they also paid for all shipping costs.
