It seem to me that I get a less holographic image from the op-amps? of
my Sony HT receiver
than I do from my Acurus DIA 100 matching levels of volume. Is that
because the Dali speakers are not far enough forward from my Sony
television? Is the television breaking up the 3D image? It seems that
there is more "forward push" from the Acurus design. Think of it as an
Aragon integrated.

Amps do tend to image differently, for reasons I do not know (here's your
cue, Stewart: "it is due to tube microphonics [quote paraphrased]"). As a
class, transistor amps seem to image "behind" the speakers. Tube amps seem
to image "in front of" or "both in front of and behind" the speakers and
seem to have more depth or "3-dimensional image body". Like all
generalities, there are/may be exceptions.

I believe your Acurus is a tube or hybrid design; the Sony HT is definitely
a transistor design. If so, that may explain it.

The DIA-100 is a solid state integrated amp with a passive pre-amp
section. Somehow I doubt Mondial (Acurus/Aragon) ever made a any tube
products.

I'm sorry, but the Acurus line certainly did include tube gear.

It is an integrated SS with a passive preamp as Harry says. The sound
stage is behind on both, although I have never heard that difference
described before. I am not sure what makes the image 3D in front, but I
am working on it. I am building a Seas 2-way, the "Eclectic", but I will
probably have to go to Quads to get what I want. Thiels are a thought.
What model Thiels, Harry?

All the floorstanding Thiels are time- and phase- coherent and pretty much
image the same way. However, most of my experience has been with the 2 2,
2.3 and 3.5, 3.6 series where it is definitely applicable. The 3.6's are
really fine sounding "moderately" priced speakers.

However, the phenomenon I speak of is also apparent on other speakers. It's
just that it seems to really show up on time-aligned speakers. As to why, I
haven't a clue. But have noticed it from the late seventies on, when I had
Maggies and ARC tubed gear. Have also heard it using Dynaco, Modulus 3,
Conrad Johnson, Precision Fidelity, and VTL tubed gear.

Really? Would you care to name an Acurus model that has a tube in it?

You are correct and I am wrong, insofar as I can go back into my annual
directories and check.
I could have sworn I remembered a salesman telling me that the Acurus line
was tube based and a lower priced line by Mondial, shortly after it was
introduced. With Aragon the higher priced line.
But everything I see in the directories back to '92 or '94 is solid state.

My apologies.
