We are currently developing a new power amplifier at Bakun Products.
It's almost complete.AMP-5521
Below is an excerpt of data from Bakun's Facebook. I'm looking forward to it.
10% Distortion Maximum Output into 4Ω: 54W
10% Distortion Maximum Output into 8 Ω: 35 W
44.3W Maximum Output Output with 1% Distortion into 4Ω Load
1% Distortion Max Output into 8Ω: 28W
Frequency Response (8Ω 1W): 20Hz: 0db, 20KHz: 0db, 50KHz: -0.6db, 100KHz: -6.29db
８Ω１０Ｗ：２０Ｈｚ：０ｄｂ、２０ＫＨｚ：０ｄｂ、５０ＫＨｚ：－０．７ｄｂ、１００ＫＨｚ：－６．４ｄｂ
SNR: VRmax: -100db, VRmin: -127db

As a non-feedback amplifier, the bandwidth is extended, and I think the distortion is decent.
One of the features of the SATRI amplifier is that noise is reduced when the VR is lowered, so the S/N when the VR is lowered is improved by 27db.
Another feature is that there is little change in bandwidth depending on the output.
