A good specimen of Klippel and Toole-based design, but it's hard to get excited about an 81 dB speaker whose bass doubles like crazy when powered up.
I hope that emphasizing "in-room sensitivity" doesn't become a trend, especially in attempts to rehabilitate units with low anechoic numbers.
I remember coveting these as in high school in the Sixties. They were being demonstrated by a local shop at the time, was really impressed with the bass (even though it was mostly playing The Tijuana Brass).
Massive woofer in these.
The THD in the A70 is not superior, but still quite transparent.
The most significant improvement, besides load-independence, is noise performance. This A70 is 9 dB quieter than the V3.
These issues are so minor Erin had to resort to a graphical magnifying glass to make a point. Which might be relevant some day when we see loudspeaker measurements also utilizing 0.1 dB grids.
No. This would be superfluous for a person who has everything.
This is the gift you give to someone new to home stereo to short-circuit any erstwhile hobbyist "upgrade" urges so they can simplify and focus on their music.
An external supply would have been useful for the earlier Wiim Amps that exhibited p.s. coil noise -- just replace the supply. And the Amp itself could have been half its current size if designed that way. I have a feeling that reducing this Amp's size and weight from its current heft might...
