 some of them which come to my mind are

1. dan d'agostino momentum
2. audionet HUMBOLDT
3. soulution 530
4. dartzeel CTH-8550
5. ch precision I1
6. vitus SIA 30

feel free to add or suggest any other ones. or if someone can comment on each of these or rank in the order of preference with their reasoning.

ASR Emitter Exclusive II. I've owned mine now for nearly nine years, and it isn't going anywhere. About 35K new or thereabouts.
I’ll stick to the Sugden brand, the world’s first Class A transistor amplifier. The A21 was the first and is still manufactured today.
Hi @goodsource, I think the hallmark feature of darTZeel is transient and decay performance. darT gets transients right in an organic, natural way that lets my brain suspend disbelief.

Michael Fremer of Stereophile uses darTZeel with his Wilson loudspeakers and you may enjoy his thoughts on the pairing, along with comparisons to CH, Ypsilon, and Boulder: https://www.stereophile.com/content/dartzeel-nhb-468-monoblock-power-amplifier
@gestalt i know fremor uses dartzeel monoblocks and i know they have stellar performance.
the question is whether the integrated would be to that level or not at their starting price point.
tonally they might be very similar and also might be similar in voicing and clarity.
question is their wattage on integrated is on the lower side and iam not sure if the integrated will have good bass performance for the wilsons.

also it would be great to know if someone did a comparison between dartzeel integrated and ch precision i1
