I've owned both latest Franks Mk2 and Dragons (first gen, with black front faceplate). I am still owner of the dragons amp. Is the low power Franks inferior? Nay. Till now, i still miss the purity and ability of Franks to extract the minutest details of the recordings. The law of physics still applies, i.e. it's a 8W amp which does almost everything superbly except reproducing the lowest bass notes with weight and authority. Based on this personal taste, Israel recommended me the dragons, YES, takes only a few minutes to discern the difference between Franks and Dragons. I stood by the dragons.
The dragons is not without fault, i.e. if you can tolerate the noise (tube noise and original dragons has no ground loop switch), heat, brightness, cost of tubes (highly recommend GE NOS 211 but very expensive), not as refined as Franks (in terms of sound floor, extraction of subtle details, etc) but your preference leans towards slightly more power, dynamics, bass weight and authority, then Dragons might be more suitable as in my case. Most of these faults are improved on the latest Dragons Mk2. Anyone interested in my dragons? :)
