Help me make sense of this - Midfi system sounding better hifi.

   I have a few systems but recently I changed the setup and pleasantly accidentally I came up with a really enjoyable system from midfi gears like Onkyo M-306 power amp, acurus pre, Klipsch kg 1.2 speakers, Topping E-30 DAC, and Ixos cables. 

   My main hifi system consists of Krell pre/power, B&W 802 D speakers, Firestone upstreaming DAC, and Transparent cables.

   The former system is considrably more dynamic and exciting to listen to - why?

   Is the Onkyo power amp M-306 that good? It's 300 watts per ch compared to Krell 200 watts - is that why the difference in dynamic exciting quaility?


   Any insight will be greatly appreciated as I am not enjoying my Uber system that costs as much as a luxury car, and getting me upset - I enjoy the midfi system that can be assembled for 1/30th of the cost...alas!


I did a little reading about the two speakers; from what I can see from the Stereophile measurements, the B&W are hard to drive; you seem to have enough power for them, but my best guess is that the synergy with the older Klipsch is superior to what you've set up with the B&W. 


"The B&W's impedance plot (fig.1) reveals the speaker to be moderately difficult to drive, with a magnitude that drops to 3 ohms throughout the upper bass and an awkward combination of 4 ohms and –50° electrical phase angle at 60Hz"

The Klipsch is more dynamic than the B&W?  Who would of thought.

Why do you call the system mid-fi?  High end is more a frame of mind coupled with a methodology.

If it was me I wouldn't feed the 802s with a Krell, I'd want something much warmer sounding.
