It seems to revv strong enough but no resultant drive power unless you kick-down. Doing this only makes me drive hard and of course, burn more fuel to do very little work.

How many miles and what kind of maintenance has been done? Is the check engine light on? On cold start-up do you get a brief rattling noise from engine 1-3 seconds?
Presently about 69K miles, no serious mantenance work done other than basic oil, oil filter, air filter changes. Also at some point, we serviced the injector nozzles too. I never observed any rattling noise at cold start. Just I'm sure that it's not delivering the desired power when I need it!
May want to have the VCT actuator function checked (tests Honda can do) and the VTEC system checked.Both of those systems , if not operating properly , will make the car feel 'athsmatic' when you hit about 3K on the tach. one is variable cam timing , the other is variable valve timing.they may not always set codes .A worn timing chain or faulty tensioner should put the light on though.
