Altmann BYOB vs. Audiosector Patek vs. 47 Labs

Has anyone compared these 3 low-powered chip amps?
Altmann BYOB
Patek
47 Labs

Which would be the most dynamic running a 4" single driver speaker which has no x-over and an efficiency of 88dB? I listen at 60-80dB.
I would like clarity and detail but chip amps have a reputation for lack of dynamics, thin sound, and grainy. Which of these 3 amps would minimize these problems?

I'm looking at the Audio Sector after having considered the 47 Labs. The integrated Patek can now be built with a Placette type 128 step RVC. I'm seriously considering it and matching it with a pair of Zu speakers.

Gmood1,

As you know from having owned his DAC Peter is pretty talented. He sent me photos of the design and prototype. Unlike his traditional non-TVC integrated design, this does not require the separate preamp module. Everything is built into the standard Patek chassis. Looks very clean.

He also sent me a link where he showed some photos of how he implemented the S&B transformers into the Patek chassis. I wish I could get one of those, but alas no more.
