Can we add 4-Pin Headphone jack amp to the suggestions? I have some 4-Pin XLR Fostex Mod's coming to me that were used. I see manufacturers are extremely proud pricewise of their 4-pin balanced amps. Is there a lower priced 4-Pin amp out there? I don't mind used... Have they been making these 4-pin amps for a years? One more thing, will it really make a difference if I get a 4-pin or just a decent amp with a 1/8" jack. I just got a Garage1217 Starlight that's setup to power my headphones. Jeremy at Garage1217 was GREAT to work with, and he loves and is very familiar Dan's Mr. Speaker headphones!!
When I get the headphones, I'll let you know how they sound.
I'll be very interested to hear your opinion of the Starlight when you get the headphones, as I'll be purchasing an Ember soon.
