Is their any headphone amps out there which will let me parallel 4 sets of headphones?
I tried the Fostex headphone 'distribution' amplifier to drive 4 sets of headphones and as you add another set, all other sets would get tilted up in the mids, despite each having it's own level control. Also, it was rather horrible sounding compared to a Yamaha CA-810 integrated amplifiers jack. (The Yamaha is in another room so it will not be used for this)
What I want to do is buy a inexpensive headphone amplifier (under 100 if possible) and drive 4 sets in parallel. No need for independent level controls. I toyed with the idea of simply using an amplifier with resistors but the noise floor was too high.
I think the minimum impedance would be around 12 ohms in this configuration (each set 40-60ohms) Various types, all dynamic--all 100 dollar level.
What I built is a 1u rack plate with 4 jacks (stereo) paralleled with a male plug on it (for the amp) so I can patch in up to 4 sets.
Would one of those cheaper parts exp. headphone amps do?
