"I really like John Atkinson and admire his work.
But I must say that in this Legacy review, I think
he is emphaszing the wrong thing, at least by implication.
Here was his chance to state what I believe is true:Rooms influence and sometimes even dominate the sound you hear.
Instead of that, he almost dismisses what he does say is a room effect(the 250 Hz thing) as in effect ONLY a room effect. Then he starts inon electronics.
Now it seems unlikely to me that the doubling of the Hafler's output impedance by running them as mono blocks will even
begin to explain any of this to any substantial extent. The amp has
a very low output impedance and doubling it it is still low.
It is true that long cable runs might influence the high end where
the speaker impedance drops to a low level--but 6 dB worth? (which
is what one see here). Very unlikely to my mind again, unless he is
running hundreds of feet of cable. And one could check this easily
by a quasianechoic measurements--whether the top was altered by the
electrical situation.
And the implication, though it is only an implication, that a
hugely powerful bass amplifier will extend the bass response as
response is wrong(he does not say this, but he sort of suggests it
by emphasizing that the bass heavier system has huge power in the
bass).
What is really going on here in my guess is room effects and
placement effects almost entirely.
I think it is one of the most fundamental errors of audio not to
concentrate on these room things. The constant harping on equipment,
and especially electronics, is misleading even if accidentally so.
The bass performance of a speaker is essentially independent of
which amplifier you use(not counting tube amps), except for absolute
volume capability. Some are a bit more extended in the bottom than
others, but the room/speaker issue is HUGE compared to the amp
issue,which is all but infinitesimal by comparison.
Of course these facts are awkward for people who are trying to sell
amplifiers, but they are still "true facts" as Thomas Jefferson
would say.
JA does not say anything that is not literally true--I never find
him to do that. But the whole tone of the explanation, with its
list of electrical things, seems to me a missed opportunity to
trumpet the honest truth about audio: rooms and the positon of speakers in them count A LOT, while electronic things count for comparatively little. REG"
