Tekton makes wonderful speakers that are quite efficient, however you may want to look at the reviews in Stereophile. Specifically the measurements as there is sometimes a gap between the published efficiency and the measured efficiency. The Pendragons have a published efficiency of 95dB. If the actual efficiency is a hair lower, this would impact your amp choice. There is a massive difference In headroom between 2w and 5w in this scenario.
I have never heard a Decware amp. I don’t know their line but will offer this advice.
I sell a different line of SETs from Art Audio. With Tekton speakers, we tend to recommend amps with a hair more power and typically steer customers toward my Elise or Carissa which are 16w or 18w SETs respectively for the reason stated. I have a hunch you will be disappointed with the amount of headroom available with any amp under about 10w with the Pendragons.
