I tend to think compromised outputstage to be noisy, prone to distortions (especially in the high frequencies) and clipping big/fast transients. Power supplies and amplifiers in circuits need special care to avoid these pitfalls, and that usually means more expensive builds (unless geniuses are involved).
However, sometimes this can also sound pleasing to the ear, it all depends on context.
In any case, I’m eager to test this new brute out!
