I owned the Pendragon's and a few other Tekton over the last few years... most "fun" speaker I have ever owned in 20+ years of this hobby. I have owned maybe 35 different speakers ranging from a few hundred to over $12,000 a pair from Dynaudio, B&W, KEF, Klipsch, Tyler Acoustics, Sonus Faber, NHT, Zu, LINN, etc, etc.
I currently own the Enzo XL and it is AMAZING sound at less than $2,000 a pair. I am sure the Focal are nice, well built speakers, but they will not come even close to any Tekton speaker when you consider the cost and nowhere near the same output vs. wattage. However, the Pendragon or the DI will likely overload that room - it will be difficult to control the bass.
I am running a 2-watt SET tube amp with my Tektons and cannot even use all 2 watts. The 36-watt amp you have will give you a TON of output on his speakers. I also have a small 55-watt SS amp that I use when it's time to boogie.
