<strong>the</strong> comp<strong>one</strong>nt-by-comp<strong>one</strong>nt description<br />
and especially <strong>the</strong> photo <strong>of</strong> <strong>the</strong><br />
Omega system on <strong>the</strong> UHF Web site.<br />
I have long been curious to see a photo<br />
<strong>of</strong> any <strong>of</strong> your three systems, but since<br />
<strong>the</strong>y are working tools I had <strong>as</strong>sumed<br />
that <strong>the</strong>y were, shall we say, less than<br />
presentable. Given all <strong>the</strong> equipment and<br />
accessories you review, I had a mental<br />
image <strong>of</strong> ankle-deep piles <strong>of</strong> mismatched<br />
interconnects and cables strewn about<br />
<strong>the</strong> room.<br />
It’s also re<strong>as</strong>suring to see that you<br />
have <strong>the</strong> same aggravating room problems<br />
<strong>as</strong> your readers (what appears to be<br />
a doorway just left <strong>of</strong> <strong>the</strong> left speaker, <strong>the</strong><br />
turntable sitting <strong>as</strong>kew on its platform to<br />
allow for access, etc).<br />
The combination <strong>of</strong> <strong>the</strong> Omega<br />
system photo and <strong>the</strong> similarly appreciated<br />
UHF No. 75 State <strong>of</strong> <strong>the</strong> Art article<br />
h<strong>as</strong> given me a sort <strong>of</strong> speaker positioning<br />
awakening. I had always understood<br />
and agreed with your advocacy <strong>of</strong><br />
placing <strong>the</strong> speakers on ei<strong>the</strong>r side <strong>of</strong> a<br />
room corner (if possible), but I had not<br />
conceived <strong>of</strong> being <strong>as</strong>ymmetrical within<br />
that placement (i.e. I had always <strong>as</strong>sumed<br />
that <strong>the</strong> corner should be exactly midway<br />
between <strong>the</strong> two speakers). Unless<br />
my eyes are deceiving me, <strong>the</strong> Omega<br />
system speakers are not centred about<br />
<strong>the</strong> corner, but are shifted ra<strong>the</strong>r significantly<br />
to <strong>the</strong> left. True?<br />
Given such an <strong>as</strong>ymmetrical corner<br />
placement, should each speaker never<strong>the</strong>less<br />
be about <strong>the</strong> same distance out<br />
from <strong>the</strong> wall (<strong>as</strong> appears in <strong>the</strong> Omega<br />
system), or can that also be different?<br />
Given a decent hi-end system and<br />
acoustics, and a stereo image that<br />
appears to originate midway between<br />
<strong>the</strong> speakers from <strong>the</strong> “sweet spot”, how<br />
far <strong>of</strong>f axis should <strong>one</strong> be able to sit and<br />
<strong>still</strong> hear that image <strong>as</strong> being centered<br />
ra<strong>the</strong>r than incre<strong>as</strong>ingly originating<br />
from <strong>the</strong> nearest speaker? All <strong>the</strong> way<br />

out until a speaker is directly in front <strong>of</strong><br />
you? Beyond even that?<br />
Given <strong>the</strong> size <strong>of</strong> standard equipment<br />
racks and <strong>the</strong> W-8, it looks <strong>as</strong> though <strong>the</strong><br />
inside edges <strong>of</strong> <strong>the</strong> Omega Reference<br />
3a’s are about 2 m apart, but only about<br />
30 cm out from <strong>the</strong> wall (that seems<br />
really close). Given that <strong>the</strong> Omega<br />
system is in a “large room” just how far<br />
from <strong>the</strong> speakers is your listening position?<br />
I would imagine relatively close.<br />
My <strong>Totem</strong> <strong>Mani</strong>-2’s are centered<br />
about <strong>the</strong> narrow wall <strong>of</strong> a long, narrow<br />
room (8.4 m x 3.5 m) having at best<br />
mediocre acoustics. They are placed<br />
way into <strong>the</strong> room, about 1.25 m from<br />
<strong>the</strong> back <strong>of</strong> <strong>the</strong> speakers to <strong>the</strong> wall. I<br />
have always <strong>as</strong>sumed <strong>the</strong>y needed that<br />
much room for <strong>the</strong>ir prodigious depth.<br />
In your recollection from <strong>the</strong> review<br />
you performed (quite a few years ago<br />
now), is that distance too great? (For<br />
reference, my speakers are about 1.8 m<br />
apart centre-centre, and I sit 2.8 m away<br />
from <strong>the</strong>m — and with experimentation<br />
I think that <strong>the</strong> 2.8 m is about 0.6 m too<br />
far away.)<br />
I had rejected an Omega-like speaker<br />
placement when I first bought my house<br />
due to <strong>the</strong> constraints <strong>of</strong> <strong>the</strong> room, but<br />
if <strong>the</strong> <strong>Totem</strong>s can be significantly closer<br />
to <strong>the</strong> wall (particularly in a cornercentered<br />
placement), <strong>the</strong>n it’s worth a<br />
try experimenting with such a placement<br />
to see if I can improve <strong>the</strong> width<br />
<strong>of</strong> my currently very narrow sweet spot.<br />
By necessity I’ll almost be in <strong>the</strong> nearfield<br />
(ano<strong>the</strong>r great UHF article), but<br />
that might help negate <strong>the</strong> poor room<br />
acoustics.<br />

Jeff, for any<strong>one</strong> who missed it, we should<br />
mention that <strong>the</strong> photos <strong>of</strong> our Omega system<br />
appeared on line in our ephemeral Virtual<br />
Room, which opened <strong>the</strong> week before <strong>the</strong><br />
Montreal show and remained open through<br />
mid-April. It h<strong>as</strong> since closed, but we expect<br />
to bring back new incarnations <strong>of</strong> it.<br />
We should add that <strong>the</strong> Omega system<br />
w<strong>as</strong> particularly e<strong>as</strong>y to photograph, but <strong>the</strong><br />
Alpha system is a lot closer to <strong>the</strong> way you<br />
imagine our systems to be.<br />
You are right that <strong>the</strong> speakers have<br />
been placed <strong>as</strong>ymmetrically in <strong>the</strong> room, but<br />
<strong>the</strong>n <strong>the</strong> walls on ei<strong>the</strong>r side are not quite<br />
identical. You noted that <strong>the</strong>re is a doorway<br />
to <strong>the</strong> left, but <strong>the</strong>re is also a doorway on <strong>the</strong><br />
right... actually a large archway to an even<br />
larger room. These are not necessarily bad<br />
things. An open doorway does not reflect<br />
sound, and thus it can be thought <strong>of</strong> <strong>as</strong> a<br />
broadband absorber. The speakers are indeed<br />
quite close to <strong>the</strong> rear walls, about 50 cm<br />
out, a distance that w<strong>as</strong> determined by ear.<br />
Speakers we review are first listened to at <strong>the</strong><br />
same distance, <strong>the</strong>n adjusted by ear <strong>as</strong> well.<br />
The speakers are actually quite far apart,<br />
about 4.5 metres, and we listen, typically,<br />
from about 4 metres back.<br />
The Signature version <strong>of</strong> <strong>the</strong> <strong>Mani</strong>-2 is<br />
reviewed in this issue, and we found that a<br />
distance <strong>of</strong> about 65 cm from <strong>the</strong> rear wall<br />
w<strong>as</strong> about right, though that will vary from<br />
room to room. By <strong>the</strong> way, how far <strong>of</strong>f you<br />
can sit <strong>of</strong>f-axis and <strong>still</strong> hear a stereo image<br />
depends on speaker placement, acoustics, and<br />
especially <strong>the</strong> speakers <strong>the</strong>mselves. With our<br />
Reference 3a speakers you can get away with<br />
being well <strong>of</strong>f-axis. The same would be true<br />
<strong>of</strong> well-placed <strong>Totem</strong> <strong>Mani</strong>-2’s.<br />
Of all <strong>the</strong> many enjoyable things on<br />
your Web site, <strong>the</strong> tour <strong>of</strong> <strong>the</strong> Virtual<br />
Room w<strong>as</strong> <strong>the</strong> best. I would love to see<br />
<strong>the</strong> same treatment to <strong>the</strong> o<strong>the</strong>r two<br />
rooms you maintain.<br />
Thanks for all <strong>the</strong> good advice.<br />

First, let me say we appreciate <strong>the</strong><br />
opportunity to have UHF Magazine<br />
review our speakers again after so much<br />
time. This new range <strong>of</strong> Energy speakers<br />
is in our opinion <strong>one</strong> <strong>of</strong> <strong>the</strong> best we<br />
have ever made and <strong>still</strong> continues to<br />
provide Canadian audiophiles with <strong>the</strong><br />
best sound available for <strong>the</strong> m<strong>one</strong>y. We<br />
were <strong>the</strong>refore surprised to read that<br />
your team w<strong>as</strong> unimpressed with <strong>the</strong> new<br />
Reference Connoisseur RC-70 speakers.<br />
This is <strong>one</strong> <strong>of</strong> our most popular speakers<br />
and h<strong>as</strong>, to date, received terrific reviews<br />
