There is NO WAY I can imagine the Verza having 5x the affect on sound that the C&C BH does for 5x the price.
I'm in awe.... wow. This amp really brings the M-100s to life. The thing is, there's so many configurations with this little thing, it's really configurable to taste. So far I prefer LOD > OUT2 with GC on low, and both LF and SF switches on. I think OUT1 is more mid centric, but I've been using OUT2 because the volume pot is less sensitive to turns and the sound has a warmer tilt.
Micro detail like never before. The bass boost is very generous, and is VERY clean, I'm extremely impressed by it. I prefer it over the ZO. The SF switch does wonders for the sound stage. It boosts the highs a bit and crossfeeds the channels giving more depth, and height it's really magical - The soundstage opens up substantially.
The amp itself (no switches on) brings the mids a little more forward, and I found the sub bass (especially) is cleaner and a tad more present; really makes the M-100 purr. Vocals have better presentation than unamped imo - especially with SF on - and background instruments are given more room to breathe. If you thought the M-100 was detailed before...
Like I don't know what kind of black magic is going on here, but the background instruments and noises are coming right out, and the soundstage has become so much more 3D. Mids are not taking a back seat anymore. Well integrated into the rest of the song. Drums, vocals and guitars are all much better presented now.
I'll come back with impressions on a different configuration later.
EDIT: Upon a little more careful listening, with OUT2 the SF switch cross feeds, and brings mids and lower treble forward, where the LF switch boosts lows generously, and the highs a little bit giving it a V-shaped EQ almost. This is a fun little amp. I don't even know if I care to get another one for comparison sake.
Glad to see another C&C BH amp with the M-100.I have similar settings to yours except I'm using OUT1 instead.
