This amplifier absolutely has raw, deep dynamic power to it. Handling insensitive 4 ohm speakers while also sounding good both at low and high volume levels, certainly could make a challenge for an amplifier. Yet the SU-V670 meets the challenge.
I have always considered, the integrated amplifier sets its benchmark when tone controls set to 0, or tone controls bypassed. The SU-V670 produces good sound any which way you set it. At low volume levels even with insensitive speakers, listening to progressive rock or even classical, the SU-V670 gives highly distinctive audio. At high volume levels, likes one hip-hop or funk, the tone controls help just blast the experience.
I have experienced a couple of hundred maybe more, amps, receivers, and I just love the SU-V670. Still, I might not recommend it to the most demanding ear.

Very Heavy, but not very good:
Sound very power, but not of good quality.
I don't like it absolutely!
