Mono blocks-High current/low impedance...options?


Purchased Green Mountain Continuum 3's. Have been tube SET/single driver guy for the last few years...Need starting point for research required to match amplification to new speakers. Thanks in advance for your help! Ralph

Thanks jmcgrogan2! Excellent lead. From what I have read so far, they would appear to be a very nice match for the Continuum 3's. One reviewer favored matching to an ss pre. Have you any experience in this area? Thanks again! Ralph

Hi Ralph,

Actually I had success with tube and solid state preamps with the M-100's. I would avoid tube preamps with high output impedence like CJ's though (700 ohms). Tube pre's with output impedence at or below 300 ohms, like BAT worked as well or better with the M-100's than the solid state preamps from Threshold/Krell/Mark Levinson that I tried with them.

Hey Vince.......

You forgot to tell us what the frequency response looks like @ 2 ohms. The current output you give is the peak value, which means only for a very short transient. All it really says is that with an 80V rail, and a 2 ohm load, it should be able to operate for a short period of time without melting.

(Of course, that assumes that the supply voltage doesn't drop under such conditions.......etc.)

But if you want an amp that puts out 1 kW into only 4 ohms, then have I got a deal for you.............

I know....behave and stop making trouble. [joke]
Hey Art - send your most robust amp hither and we'll smoke it. ;)

By the way, my speakers are .8 ohm. I don't listen to music higher that 90 dB as a rule. With Henry's Fire preamp, I'm getting +20 amp transients. There is a nearby audiophile that is using the stereo version of the H2O Signature on 4 ohm speakers. The percussion was terrifying.
