Current recommendation for instrumentation grade audio interface

[Rja4000]

It can be switched to:
0dBFS input impedance
1.7Vrms 640Ω
2.7Vrms 1kΩ
3.5Vrms 1.3kΩ
4.5Vrms 1.66kΩ
6.7Vrms 2.46kΩ
7.6Vrms 2.82kΩ
8.5Vrms 3.12kΩ
10Vrms 3.48kΩ
43Vrms 13.6kΩ

Those are balanced impedances.
Unbalanced is lower (Ivan says by 30%)

The Cosmos ADC costs $160 and can do at least -130dB THD:

I understand, but at this point, given its practical insurmountable challenges - such as the need for a preamplifier that's not available yet - what I said stands.

It simply cannot be used as an RME or Lynx can, so I don't think the comparison is valid.

There are interfacing expectations (impedance, level, etc) that are typically required from such a device that the Cosmos ADC doesn't offer. It's almost like an internal module that performs incredibly in some ideal situations, but actual devices offer real world performance because of their several "accessory" stages and internal modules that support expected functionality (and may diminish their absolute performance, but that's an assumed "loss").

(Which is not meant as a criticism of that ADC device. I am excited about it and ready to try it when it can serve my needs)

I have the ADI-2. I recommend them. The ONLY downside is lacking ON/OFF power button.

I use it for my PS3. It has enough power to drive my HD650 too.

The thing can resist a nuclear bomb easily.

Which one, the old one that doesn't have USB?
If yes, how do you connect it to the computer and if there are any downsides to using it.

Correct, no USB.

The other one is called DAC.

Why I would want to connect a PC? Connection is between CD/DAT/DVD/PS2/PS3/XBOX/etc to ADI-2, and then to headphone, speakers, etc.

But you can still use it with PC, just use SPDIF output (from PC) to SPDIF input (on ADI-2).
