Altmann BYOB vs. Audiosector Patek vs. 47 Labs

Has anyone compared these 3 low-powered chip amps?
Altmann BYOB
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?
Interesting Clio, Peter told me he had some form of RVC volume control in the works. He has been working on that for well over a year. Nice to read he's implementing it into his integrated. It should sound fantastic!

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.
All good stuff you probably can't go wrong with. The BYOB will do what you need and honestly, I do not believe it is a chip amp. I'm no expert so I may be wrong, but despite its looks, I think it is a traditional amp. It is also mighty powerful and better sounding than a lot of stuff out there.

I was thinking about giving one of Pete's amps a try -- maybe one of his newer Patek integrateds. I would love to try one out for a while. Best,
