Yesterday, I was lucky enough to borrow my friend's Roksan Caspian power
amp. I used my Marantz intregrated as a preamp and I was on my way.

The only noticeable difference right off the bat was the that the sound was
louder at lower volume levels, though this can be attributed to the fact
that the Roksan was rated approximately 20wpc more than my Marantz.

However, there were definitely certain sonic differences without indulge in
superlatives like "lush" or "rich".

A small example - about 3 minutes and 30 seconds into Welcome to the
Machine, there is a very pronounced series of splashes on the right channel.

I've heard the song 10,000 times before and every time it sounded like
background noise layered over by the guitar and synth work. But last night,
the cymbals really shone.

I've always been a bit of a skeptic as far as the value of multi-thousand
dollars amps and preamps go, believing the money is better spent on
speakers. But I was really floored by the difference in the detail that the
Roksan provided.

No, if the sound is louder at lower volume levels, it means the Roksan is
distorting more.

Good point, Tim. The power difference probably is too small to register any
difference in the loudness. Hmmm. Acoustics, perhaps?

Perhaps the amplifiers have different gains, and you're not setting the
pre-amplifier volume control accurately when you switch betwen power amps?

The few audio pragmatists here would agree that possible "differences"
between amps are possible. But we would also agree that these "differences"
are mostly irrelevant, given that other issues are much more important.
These include the difference that is created when a speaker is moved, say,
100mm - something that would have a much greater effect on the sound than
any "amplifier difference".

The problem for the audio ratbags is that they take the existance of a
"difference" and then attempt to rank the different items. This is
impossible under current technology. One persons "colourations" are another
persons "normalacy".

Hi,

Most probably, if you would go back and listen to the same sequence with
the marantz now, the "cymbals" will "really shine" in that one also, now
that you've _learned_ how that particular sound is supposed to come out,
courtesy of the roksan.

The learning effect ... this is one aspect of human hearing the DBT/ABX
protocols needs to address if they are to ever become accepted as
scientifically valid methods of testing the differences between audio
products.

NOTE: I have some spare time from projects and came back to read the
group to get some info on the krueger/Atkinson debate. Couldn't
resist the urge to put my two cents of worth forward on this one.

Well, DBT's *are* one of the validated scientific methods for testing
subjective differences.



Sure.

I never really experience it that way. Once I hear great improvement using
different components, I tend to forget what those sonic improvents were
after say about a week... or a month after removing that particular component.
I easily recognize those improvements once I put them back again.

I just think that some people are sensitive listener than others. Years ago,
I remember a friend who was already an audiophile then who invited me
to listen in his system and keep asking me to listen to the excellent
basslines to a bunch a songs and I couldn't figure out what the hell he was
talkin about. I keep listening to the songs which he keep playing repeatedly
and all I hear is the loud voices, the cymbals and the sound all around the
room. That just the way it was for me during that time and for a long time.
I would keep on focusing to a particular instrument but I get easily
distracted
by the rest of the sound. Not so anymore. And it was like magic after I got
around to it. Listening to a particular instrument in well recorded songs
now actually is quite stimulating. It's easy as 1-2-3.

Why did you scram anyway, I forgot.

The possiblity is real, that there was/is some sort of difference
between your Marantz and the Roksan that caused you to hear something
you had not noticed before. There is also the possibilty that you just
happened to hear something you had not noticed before, irrespective of
the change.

Thankfully we know how to find out for sure. There is a method for
determining real differences as opposed to imagined ones. The
possibility exists that you just may have been listening differently
BECAUSE you had a different amp connected, not neccessarily becuase the
amp was different sounding.

IF THEY ARE TO EVER BECOME ACCEPTED AS SCIENTIFICALLY VALID METHODS?

My good sir, they are already accepted as scientifically valid, by
everyone except a tiny minority of high-enders.

Interesting. That has not been my experience.

The absence of a time-synchronized, level-matched

And how many did *you* perform when you described the abysmal sound
that you heard at the NY show?

Absensce of anything meaningful to say noted.
