Ken - given how good the M5-HPA/Quatro Wood CT combo sounds, I can only begin to imagine what your M7/Model 7 MkII sound like!

As per my knowledge it's a minimalist solid state design outputting 300 watts into 4 ohms and 150 into 8. The 15,000 a pair amps driving a pair of moderately priced Vandersteen Quatro Wood CT speakers produced the best sound I heard yesterday, with a midrange transparency that kept me listening for more than a half hour to my high resolution files from vinyl.

LanePanet, welcome to AA! :thumbsup:

The monoblocs have been burning in nicely through the holidays. The synergy with the Quatro Wood CT is well nigh perfect. The insight the combo gives me into my music, especially in the midrange, is enchantingly addictive. The bass foundation is simply tremendous. Organ notes below 60Hz especially flourish through these amps. Mid-bass thwacks are visceral. Music has propulsive pace and rhythm. The overall sound is simply more immersive and intimate.

The Benchmark AHB2 I was using in my system before gave me enormous insight into what was in my music collection compared to my old Classe CA-2200. It remains a valued component in my possession. As such, I'm searching for a good pair of speakers for it.

The M5-HPAs realize the full potential of my system with my Quatros and give me a smooth yet detailed sound that is to me enchanting.
