More costly to build, less demand, and bad economy. |
Jylee and Charles1dad, I couldn't disagree with you more. I have yet to hear any of these more efficient speakers that satisfied me. |
Mapman, these newer Class D amps with their relatively inexpensive, diminutive dimensions, cool running, high current, high powered prowess just might free up speaker designers from the limitations of meeting the criterion of high efficiency speakers. The future just might be the opposite of what you predicted. |
Mapman, that depends on what your defining as more and what your defining as less.
I suspect your suspicions are spot on. |
Your Stax "ear speakers" are, ehem, a different can of worms. |
They aren't expected to fill a room with sound. |
Charles1dad, I couldn't agree more. |
Hack, remember that a high current amp will decrease power into higher loads. There are limitations in either case. Choose your speakers and amplify them appropriately. |
Al, I always welcome your posts. The "PROVIDED" you provided is the operative word. |

Hack, a high current amps prowess might be lost on a speaker with a 16 Ohm impedance. |
Tvad, I for one would hate to lose you, and your valued balanced contributions to this forum. This particular thread doesn't seem that contentious to me. I do hope you'll reconsider. |
I think some people, especially those running ss amps, are comforted by the idea that there is nice margin of available power away from clipping. Others claim that some distortion is audible from stressed amps before full clipping occurs. Some times the extra power is not that much more expensive. Some amp manufactures claim that their Class AB amps slide from Class A to Class B at a ratio of power, e.g. 20% of rated ouput. Some amp manufactures claim that their Class A amps are only capable of sustaining full Class A output at their 8 Ohm rating, as the impedance drops so does the ability to maintain Class A output, e.g. at 4 Ohms those amps are only capable of producing half their typically rated output into 8 Ohms in Class A. If that's the case, the higher powered amp(s) might sustain higher quality sound further into power demands, though not quite up to full available power output. |
Why would you want less power then? |
One can and sometimes does hear in excess of 110 dB. It's not just the volume, but the duration and the frequency that one hears these peaks that are of concern. When it's appropriate, it's nice to have the capability. Some speaker can handle it without significant distortion. |
Caveat: I know nothing about the seller:

Irv, I guess you didn't see his $2K budget limit? |
Weseixas, If some have speakers that don't operate within those impedances, why would it matter to them? |
Well Weseixas, I think we part ways on your appraisal of Class A. More often than not (but not always), I've found the more Class A the better the sound. The only problem is many so called pure Class A amps either don't have enough power for the the speakers I prefer, or the cost is beyond my budget. ...And of course, the issues of size heat, efficiency, etc.. |
I hate to repeat myself, but a Threshold S500 with new caps and a re bias appears to be just what your looking for. Though Threshold made very well received pres, many used them with tubed Audio Research and some used tube c-j pres. If memory serves me correctly the input impedance was 75 KOhms. 250 Watts per channel 8 Ohms, 500 Watts per channel 4 Ohms. 20% Class A bias into 8 Ohms. Class A bias halving as power doubles into 4 Ohms. |
That seems like quite an impedance swing from the Cary. I'm not sure I would want to be married to it. |
I'm not that familiar with your speakers and didn't take the extra time Ngjockey took took to consider system compatibility. My suggestion was merely based upon your posted request. |
I admired your effort. I do wish you a speedy and pain free recovery. |
