Hi,
Just my personal experience but I use a 8 watt mono block SETamp with the de-cappos at 92 db. they drive them loud enough in a medium sized living room without clipping. The de-cappos don't have a crossover to get in the way of the signal,so it's a cleaner more direct presentation. I would suggest a more efficient speaker and not change the amp. PP amp will generally not be as clean and detailed in the midrange.BTW my room is 24x14x11.
p.s. Another thing to consider,taking your point of view is how is the Unision costructed i.e. point to point wiring,type of transformers, tubes that you are using,tube rectification etc.
