to be honest, i shouldn't say they sound the same w.o a/b comparison.
However, I spent 3 hours last night with the new amp at very low volume and I didn't miss anything, sounded so sweet and pleasant. I temporary used the Marantz SR7000 to drive the speakers while looking for the amp and it just struggled so hard that forced me to get the amp asap. I am happy that i didn't get the HK3490.
One thing I found that when I turn off the amp first w/o pre-amp, I can still have the amp drives the speakers for a few second but the sound is dying out.
That must be driven by a huge caps? does it do any harm to my speakers?
thanks guys,
tran.
