Any thoughts on Denafrips Terminator Plus

I went from Benchmark DAC2 to Terminator. I still have the Benchmark so I'll put it back in to see if any useful observations emerge.

In my system, it took about a month to acclimate to the Terminator.  At some point in that process it seemed to exhibit that old "loudness" button sound for low volume. That is, bass and percussion seemed fully "there" before vocals, which gave a sense of instruments moving forward or in front of the singer.  But I realized that if I brought the voice up to "there" then everything sounded glorious without excessive bass or percussion. It's almost like an instrument that you need to fully engage, and then it's revelatory and involving. But this is "in my system" and there's so many variables, especially speaker response.

As for the DDC's, the Iris seems awfully close to the components in the existing USB input of the Terminator, and the Gaia has lots of stuff I don't need, so I'm hoping the upcoming Hermes hits the sweet spot of maximizing to USB to I2s path.

I am trying to understand the point of the DDC units from Denafrips. It seems to me that the benefit, with respect to the Terminator line, seems to be to allow the use the I2S input.  the I2S input is stated to be the best input on those units. Is this the correct?

If you had a different brand DAC that did not have I2S would these DDC units from Denafrips have any benefit? Assuming the DAC has a very good USB input. 

Some extra info from Alvin:

The GAIA is the flagship DDC with OCXO crystal oscillator. It's engineered with multistages of superb linear power supply. If you've decided to go for the Terminator-Plus, the GAIA may be of luxury as if you use the clock-out from the Terminator-Plus to connect it to the DDC Clock-In, the internal clock is bypassed. Hence, rendered the OCXO in the GAIA redundant. A customer tried the IRIS with the Terminator-Plus, he is loving the combo:

If you're connecting via USB to your DAC, then I would not expect you'd see much benefit. They might reduce noise a little, but your DAC is going to have complete control of the clock since USB passes data asynchronously (at least any virtually all relatively modern DACs).

I think the benefit of the DCC (particuarly the Gaia) would be to take advantage of it's very accurate clock, so you'd need to use a connection that passed the clock along with the data (SPDIF, AES3, I2S). 

Hi Guys 
all of this talk about Dacs,I have been in this hobby for over 35 years and the only 
Dac that compares to my analog is R2R ladder Dacs period.
Try Holo Spring or Denafrips Terminator 
Peace
