I've heard the VAC 160 with the C7es3 and it sounded wonderful. I will say that there was also a very nice REL sub in the mix. It might have not been needed. I didn't need a sub when I had a Rogue Cronus Magnum with my C7es3's.
What type of sound are you looking for? What music do you listen to? I've had a few integrated amps with the C7es3's. Actually tonight is my last night with them after 6 years. My dealer is stopping by tomorrow with my new HL5 Plus's in Tiger Ebony.
Leben amps are popular with Harbeth owners because the Japanese love Harbeth. The Japanese aren't much into speaker manufacturing but they make some serious electronics and they love Leben. I would like to think the VAC would be in line with the Leben but I've never heard a Leben.
If you live anywhere near Rochester NY, I might be able to set up an audition with the VAC and C7es3.
