Which watts are the right watts in SS amps?


Hello Sports Fans!

More than a few people over the years on these pages have said only those SS amps which double down in output power as impedance drops are truly special or worthy amps. Eg., 200 @ 8ohms; 400 @ 4 ohms; 800 @ 2 ohms; etc.

Not every SS amp made does this trick. Some very expensive ones don’t quite get to twice their 8 ohm rated power when impedance halves to four ohms. BAT, darTZeel, Wells, and Ypsalon to name just a few.

An amps ‘‘soul’’ or it’s ‘voice’ is the main reason why I would opt in on choosing an amp initially and keeping it. Simultaneously , I’d consider its power and the demands of what ever speakers may be intended to be run with it or them.

I’ve heard, 80% of the music we are listening to is made in the first 20wpc! I’m sure there’s some wisdom in there somewhere as many SS amps running AB, are biased to class A Only for a small portion of the total output EX. 10 – 60 wpc of 150 or 250 wpc.

After all, any amps true output levels are a complete mystery when anyone is listening to music anyhow.

I suspect, not being able to actually measure true power consumption, the vast majority of listening sessions revolve around 60wpc or so being at hand with traditional modern reasonably efficient speakers.

Sure, there are those speakers which don’t fit into the traditional loudspeaker power needs mold such as panels or electrostats, and this ain’t about them.

The possibility of clipping a driver is about the only facet in amp to speaker matching which gives a person pause while pondering this or that amplifier.

I feel there is more to how good an amp is than its ability tou double output power with 50% drops in speaker impedance.

However, speakers are demanding more power lately. Many are coming out of the gates with 4 ohm ‘nominal’ IMPs which lower with fluctuations in frequency. Add in larger motors on larger drivers, multiple driver arrays, and on paper these SOTA speakers appear to need more power.

IMHO It is this note which introduces great concern.

I’ve read every article I can find on Vienna Acoustics Music. Each one says give them lots of watts for them to excel.

Many times good sounding speakers I’ve owned sounded better with more power, albeit from arguably a better amp.

I tend to believe having more than an adequate amount of cap power is indeed integral. … naturally the size and type of transformers in play possess a strong vote for an amps ability to successfully mate with speakers.

Controlling a driver’s ability to stop and restart is as well a key to great sound and only strong amplifiers can manage this feat. Usually this gets attributed to ‘damping’ factor, but damping as I read it is more a shadow than a tangible real world figure as it depends on numerous factors. Speaker cable length alone can alter damping factors.

A very good argument exists about those mega watt amps voices. Each 500 or 600 wpc amp or amps, I’ve heard have had stellar voices too, not merely more watts.

So is it predominately these mega watt power house amps souls or their capacities that fuels the speakers presentation?

Would you buy an ‘uber expensive’ amp based more on its voice or soul, than on its ability to output loads of watts, even if you feel the amp may be somewhat under powered for the application?

Choosing this latter option also saves one money as the more powerful amps do cost more than their lower outputting siblings.

Please, share your experiences if possible.

Tanks muchly!

This is incredible...A guy (I assume) who quotes articles and magazines to prove a (technical) point is challenging someone who’s been designing, building and selling power amplifiers for a living, on a technical level of all things...
Really interesting....

P.S. I like it better when he's pushing Schiit products as the best thing after sliced bread...
Ralph - I sincerely hope these sorts of (nonsensical) debates will not deter you from sharing your wealth of knowledge and experience with the rest of us here. Thank you for all your contributions.
Ralph, have you taken a leave of your sense of humor ? If your amps are as rigid and boring as you are today, who is going to choose them ? 
Anyway, Gryphon is the power choice, this is as clear as the fact that it won't give you the most sophisticated sound possible. That is for tubes to deliver.

Schiit is probably the best bang for buck on the market, better performance per dollar than that McIntosh blue xmas tree junk you have with autotransformers. I'd stack the Schiit Vidar at $699 up against it on speakers they could both drive easily.

And yes Ralph as inna pointed out, are you nutz even suggesting any of your amps would compete with the Gryphon I mentioned on a speaker such as the Wilson Alexia, or others even with similar hard varying loads.

Cheers George
I now have a pair of 99db efficient (allegedly) Klipsch Heresy III speakers that seem to work very well with my silly little 12 watt per side SEP amp.  To put this in sophisticated audiophile terms, it can now rip the paint off the ceiling and fry your head. Isn't that what one wants? Also my new Schiit Freya preamp with upgraded tubes (no biggie, simply a set of new Tung Sol 6SN7GTBs until I find something more exotic to play with) sounds real good in this combo….note the amp, preamp, and speakers were all embarrassingly inexpensive, so I shall remain embarrassed. Feel free to mock me….I can take it.
