Weight vs Wattage vs Current vs Slam vs Value


Although I have no expertise in contrast to others, in regards to what is the best amp, be it SS or Tube especially considering the cost of the amp, used or not...I wonder what is in your opinion the best indicator of value. The definition of value here would be in all term the perception of the listener of the sound that he/she is likely to hear with the amp in the proper set up....
Some of the strangest things I have heard perceived while reading through audio ads and other post are things like

Odyssey amps.....comparing their amps and the their value in terms of watts vs cost...being very affordable in comparison to other manufacturer's amps....I am very skeptical about their line.....continue reading the other ideas I have come out with...

I had a pair of Carvers, they were light and yet it seems as if they produced some impressive Watts....my M 4.0 t produced 375 watts per channel and weighted about 25 lbs or something like that....but knowing by experience, these were the most ANEMIC watts I have ever had the pleasure of producing. Very weak when attempting to run tough loads.


Class A output SS amps....tend to be heavy, but their wattage seems to be low. I am curious about Clayton and their famous S-40? That produces 40 watts, but are tauted to have a lot of power in the perception of sound....Does this mean that a Clayton S-40 has more slam, soundwise as my DNA 225? If this is the case, what about Clayton S-40s versus my BC 2 monoblocks? Each having 75 watts of class A power+ being 75 lbs each? I do not remember my BC-2 having that much sense of SLAM.

The monster amps have a lot of weight, but then, they cost nearly as much and at least, perception wise (especially Krell/Levinson) have a lot of slam in their sound
Some SET amps, being low wattage, I have read somewhere that even THEY can have a sense of slam if properly set up...I.E: context of how they are being sonically displayed, perhaps with a huge folded horn set up.

And this question goes on and on....

Would like to have a list of amps, be it classic or contemporary with a small comment on their WATTAGE, WEIGHT and their sound characteristic...be it neutral, soft, dark, SLAMMY? etc... and your rationale about why each one of them are either excellent in value or very poor.

Well Paul I can tell you an amp being heavy has nothing to do with slam..more dependent on the speakers.I'am using a 60 wpc Dynaco st120 modified more than 10 yrs ago by Van Alstine.It weighs roughly 18 lbs.Has more slam than a 300 wpc Mac I used to own.Me and a friend just refurbed the binding post,input jacks and changed the aluminum wire from the inputs to the pcbs with solid copper 18 awg wire.All for less than $20.00.The sound is weighty with clarity.Not a hint of grain or hardness.Very open and precise without fatigue.Have had to go back and listen to all my cds over again!For $120.00 investment not even my beloved and now parted Music Reference RM9 MK2 could go there! This one I will have for years to come.Price per performance I haven't owned a better amp!
I would go with the standard list of measured performance tests on the model of amplifier you are considering, conducted by knowledgeable technicians (this should eliminate most magazine reviews right there, either they simply don't measure, à la TAS, or else they seem to be a bit inconsistent from test to test and draw rather strange conclusions, à la Stereophile) and then I would go straight to listening to the damn thing with the rest of my associated equipment. Or you could do what some magazines have done in the past and use the price/pound ratio... I fear that no rule of thumb such as those you suggest is applicable. My own prejudice tends to favour heavier amps. The weight must surely come form a healthy power supply. So, I guess, conventional class AB and class A amplifiers would surely win this test. In the final analysis I am afraid you will have to trust your ears, you would be amazed at how little amp may provide great sound to your ears. The amp should never be looked at in and of itself, but as a marriage between it and the speakers it ill drive. No simple solution, I fear.
the bottom line is the current output capability the amplifier can deliver into your speakers, usually specified in amps continuously and peak measurements. A Rowland model 1 is only 60 watts but has nearly 60 amps current output.
Gmood1, I think what you are saying is a valid point, perhaps if we get a super sensitive set up, as in a completely folded horn type of loudspeaker set up, even a 1 watter amp will out do many heavy weight, wattage intense amps which might run a huge, heavy weight and inefficient speaker set up. Nevertheless, I keep hearing about these people who have these inefficient, and yet powerful amp set ups and they keep talking about the slam factor when it is being played. It intrigues me.

Mejames, does it mean that any Rowland amp, like the one you mentioned with out do another amp, with a higher Wattage and weight, with the same speaker? Have you compared this Rowland with other heavyweights such as Krell or Levinson?

Can there be a 20 watter or less than 100 watter amp, which will sound faster, more powerful than a 300 watt set up. Perhaps slam, as listeners perceive it might have more to do with how FAST the amp discharges current, as it is asked by the loudspeaker set up. Does this make sense Mejames?
yes I agree partially with your statement, the speed the current is transferred into the speaker would definitely tend to affect the perceived slam factor [the quicker the better] but if your speaker needs 30 amps for a given transient and your amplifier can only supply 10 amps I don't believe its speed would matter then. example if amplifier 1 deliveries the required 30 amps in 600 microseconds and amplifier 2 also delivered 30 amps but in 300 Microseconds [twice as fast] amplifier 2 would have more perceived slam definitely. I believe the Carver 4.0 has about 22 amps peak output each channel where the Rowland is 55 amps peak per channel and its their smallest amplifier. one listen to a high current amplifier will quickly teach you that watts are really irrelevant.
