Just use the direct power amp input and you will have a very good full fisted and controled sound. One of the best technics amplifiers.

I Cant agree with ilkkasuni that this amplifier meets the challange or that it sounds good only that it has some power but thats it but i agree with him that this is not to recommend to the most demanding ear...me myself would say to the least demanding ear.

Ive always used pioneer and right now im using pioneer A-445 and the quality from it is like comparing night and day with this one, alot better sound quality and im alot more satisified with my pioneer so i sold this amplifier which i see as a piece of crap.

So my conclusion is: if you dont care about sound quality and want that extra 15W(compared to pioneer a-445) on your speakers be my quest and buy this amplifier...

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!
