Brownsfan,
I appreciate the effort, time and patience it requires to carefully compare
three different amplifiers with a speaker and listening to multiple
recordings, thank you. My gut feeling for the Dennis Had amp's diminished
bass region and symphonic music performance is traceable to the power
supply and transformer quality. The Dynamo and the Had amplifier have
identical watt ratings yet you noticed a considerable performance gap
favoring the Dynamo. The Frankenstein's higher level outcome isn't
surprising, it doesn't have the cost constraints and can utilize superior
parts(and bigger/better transformers) without that concern. Symphonic
music at 99 db SPL peaks
presented "cleanly" with the monitor sized 92 db sensitive
deCapo is very impressive. Interesting your comments in comparing it to
the 500 watt Cary SS amplifier in terms of driving this speaker. The brand
new Dynamo should get quite a bit better with adequate burn in and better
tubes as you noted.
