Hello all......first time poster. My question is....I see that the A-100 and the TA-100 both have headphone capability. Is there sonically a difference between the two headphone amplifiers ? I read that the A-100 can utilize the entire output to drive headphones. Can the TA-100 do the same ? Is the TA-100 headphone amplifier just an amplifier on a chip or something else like old school dropping resisters ? I like the flexibility of the TA-100 (don't need a tuner though) however I am just starting to get into headphones. Thanks all for your insight  Radioman |

I have a TA-100 and I use it for both the DAC and a headphone amp to drive a set of 300 Ohm cans. It does not use the power amplifier to drive the headphones, but the headphone amp that is in it is robust enough to drive my Sennheiser HD650's to ear bleeding levels, and with excellent bass authority.
There is a thread around here were Keith L. describes the headphone amp that is built into the TA-100.
The TA-100's output power to headphones:
Output Power:
8 Ohms: 23 mW / channel.
33 Ohms: 90 mW / channel.
47 Ohms: 127 mW / channel.
150 Ohms: 145 mW / channel.
300 Ohms: 114 mW / channel.
600 Ohms: 75 mW / channel.

Hi there! I have heard the PT-100 which sounded fine with the HD600's. Think of it similar to the quality of the DC-1's headphone amp. However, my man, the A-100 is the Schiznit in direct drive mode. I've tried them both with the HD600 and HD6XX extensively. Huge amount of power and better clarity. Buy both is what I would say. Say a PT-100 coupled to the A-100.

I just today opened my A-100 and put the jumpers on for direct drive with my HD6XX cans. Wow, did they come alive. I thought they were great before, but this was another step. Highly recommended!

One of these days I'll get around to hooking mine up and trying this. They sound pretty good already with my Schiit Fulla 2. |
