In my search for a tube preamp, I came across a couple with USB outputs! I am curious if anybody here has any experience with these? Here's the most interesting one.

HIFIMAN EF2A USB Headphone Amplifier

Both USB & Analog Inputs The EF-2A sports both a stereo analog input and a USB B-type input. Switchable from the faceplate. The analog input is very good in its own right offering astonishing transparency for such an inexpensive product. The USB input allows the EF-2A to make use of its Burr Brown PCM2702 D/A converter and offers far greater sonic performance from your computer than using the headphone output.

The DAC in the EF-2A supports up to CD quality resolution (16Bit/44kHz) via USB.

An affordable alternative in a tube-driven headphone amplifier, the EF2A is a hybrid design, USB headphone amplifier using 6J1 tubes for its input stage and incorporates a Burr-Brown PCM2702 DAC Chip. The EF2A provides USB input and features 16 bit 44.1 kHz performance.

"The EF2A provides USB input and features 16 bit 44.1 kHz performance."

This is the problem. 16 bits isn't going to be of any use.

I don't understand why a tube headphone amp is desired....
Don't you want less noise floor in a headphone amp?
Just asking..... no particular opinion.

Actually, I was looking for a tube preamp. One that was USB would be great. But it's limited to 16 bits which is a deal breaker.
