AFAIK This amp does a wonderful synergy with my Denon C301. I was using my ZO for the last weeks, but the ZO has ran out of battery so I did change for the BH since I haven't charged my other amp yet.
It does a superb job. The soundstage is spacious, the mids and highs are clean and natural, the bass is of course not as pushed as the ZO's bass, but it is dynamic and clear. It thumps like a subwoofer would do, but not like a boomblaster would. If you see what I mean.
Every time I switch from a gear to another between my babies I can't help but think that "I already have some serious things there, I love these!" and I'm not in Summit-Fi haha, just a couple of portable amps, some headphones and earphones, a Boombox and way to go.
I don't think that I could have found a better amp for its price (I got it for +-55$ new and shipped).
