What is missing here?


In this months Absolute Sound magazine there is a nice review of an amp that many of us would probably consider based not only on the review but on the topology utilized with the amp. The amp in question is the new Air Tight ATM 300R. This amp utilizes the 300B tube and according to Dick Olsher " The Air tight ATM300-R wowed me with countless hours of listening pleasure. It consistently brought to life the full sonic promise of the 300B". Sounds amazing right??


Except, nowhere ( except in the specs section) does it mention that this amp is limited to 9Watts/Ch!! And at that it is putting out about 10% distortion! So not only is the amp severely limited to which speakers one can match it to, but those speakers had better be ULTRA high efficiency. While most experienced a’philes will expect the extremely severe limitations of this kind of max output, how many casual listeners who read this article will realize the extreme limitations that this amp comes with? Certainly none of that is mentioned in the review, which brings up the question...why not??? How many even somewhat seasoned a’philes have made the mistake of matching a flea powered amp with a less than favorable speaker load? Let’s hear about it....

For an 87dB speaker, 8 watts will give you 96dB at 1 meter. Pretty loud.
If you're buying a 300B amp, you'd have to have done some research. 
Why attack low-powered amps rather than inefficient speakers? ;-)
@daveyf I used run a Class D T amp which has about 3 watts! In fairness, it didn't crank well. It is remiss not to include the output in the specs. Maybe they forgot. Perhaps AS assumes anyone who knows their stuff would know the 300B in SE mode only does 8 watts!
Agreed. Reviews used to be shootouts between competing components. Now they are just glorified write ups of products already deemed praiseworthy by the publishers and serve no useful purpose other than light entertainment.
