Suggestions needed for an SS Stereo Amp w/+175wpc

Bob,

Efficiency in the sense that the power output doubles into 4 and then even into 2 ohms, not overall power delivered out versus consumed.

The Carver was a m4.0t, solid state, 360 watts/channel into 8 ohm but only marginally higher into 4 ohm (not even close to 720 w/ch), and not very high current delivery compared to most other "monster" amps with similar power specs into 8 ohm.

Mapman, in my opinion you've offered some really excellent, valuable comments.

The one thing I would add in the way of clarification is that your item 4 really equates to your item 3 + item 5. In other words, the reason that the ability to progressively double power as load impedance is halved is significant, is that it signifies that the amp has both high current capability (relative to its power rating) and high damping factor (which is the same as low output impedance).

"Efficiency" is probably not the best term to use for these capabilities.

Best regards,

Al, thanks for the clarification and glad I didn't mess that all up too much.

Not sure about the output impedance of the Carver m4.0t.

I can't say for certain that bass levels were lower relative to other frequencies at lower volume than at higher volume for certain. It could be that the lower bass levels were just more noticeable as deficient at lower volumes. At high volumes, the rafters could be shaken by the 360 w/ch without any major tonal balance issues that I can recall. The differences in specs between Carver m4.0t and MF A3CR I recall that I could attribute this to were the power rating into 4 ohms, the damping factor, and/or the current levels available.
