I’ve owned a handful of quality IEM and only one pair of used DJ8 Sennheisers. I’ll cut to the chase and say that I was pretty excited after listening to the GR-1 for about 15 minutes. My first listen was on the TA-100, which was more of a “oh, ok, that’s really nice”. Then I hooked up to the DC-1 and it became more of a “Wow! This is great!”.
does anyone understand the components of each headphone amp? Why does the DC-1 sound better than the TA-100?

It's actually got TWO headphone amp circuits on it, each independent of the other to give you two outputs. The DC-1 had a reasonably powerful output which is likely way more powerful than the TA-100. \ I believe it could provide more than a watt of power at the 32 ohms of the GR-1 which is quite substantial. A lot of circuits might max out at 50 milliwatts but the DC-1 can provide more than a 1000 mwatts of power. For the most part the DC-1 has an overall healthy output and I assume reasonably low ouptput impedance. For high impedance headphones like the sennheiser HD600 and HD700, the Emotiva basx A-100 with its dropping resistor bypassed provides significantly more power and control. But for low impedance headphones the Dc-1 is likely much cleaner in noise. The DC-1 also has a separate digitally controlled analog resistor ladder on a chip circuit for the headphone amp circuitry. This is separate from the regular analog outputs which also uses its own digitally controlled analog resistor ladder. The resistor ladder means even at lower volumes its channel balance should be quite good. Here are the DC-1 headphone amp power output (from keithl)

OK...so Garbulky's answer was more detailed....but mine is right too. I use my DC-1 as a preamp, never tried using headphones.....guess I should think about getting a pair.

The DC1, from Emo’s glory days, was one of their premier products.
Sadly, for two channel, they now offer “refurbished” xmc-1 “pre pros” (whatever that means) as your best alternative.
Maybe they will become competitive in the two channel market sometime again.
