The HFW review claims that they tried both the single transformer and
double transformer PSUs and this (they said) had no effect on the
limited power into 4 Ohms. This is very odd if so. Hence their review
may simply be in error. However it is difficult to say without some
more reliable info. Unfortunately, plain errors of fact do occur in
reviews. [snip]

Alchemist did specify that the additional PSU was a sonic upgrade and
did NOT increase power

That is quite curious. It implies they are concerned with 'crosstalk', but
not with the peak/mean powers available. If what you say is correct it
implies a deliberate design as otherwise doubling the PSU would tend to
change the available power. Seems odd to specifically prevent this. Did
they give a reason for deciding to prevent the dual PSU from providing more
power?

It makes it sound like either they had a quite specific (unstated) 'sonic'
reason for preserving the clipping/limiting behaviour, *or* that they were
concerned about the IV safe operating areas of the o/p devices.

[snip comments on file size]

Not at all - I take your point and urge you to seek broadband and, if
not available, to move into an area where such a facility is available
P

:-) I don't normally download/upload much per day, and prefer to keep my
total costs down. Hence I have avoided broadband thus far. I'm afraid that
I like where I live too much to consider moving for something like this.

However, regardless of the above, the info you have provided is
certainly welcome, and I am glad you have produced the files/pages for
people to access. I tend to be over-sensitised about the above issues
as I use non-Windows/Mac machines and have a history of producing
'educational' sites where one of my concerns is "Will people in third
world countries,
or
who can't afford new kit be able to read this material?"

Right on! I've found *nix users tend to be sensitive about such issues
)

FWIW I don't use Linux, either. :-)

I *do* use Solaris (UNIX) a bit, but mostly use RO for day-to-day deskwork.
My main concern, though, was that it took about 15-20mins to fetch a
(6MB) PDF. This isn't an OS issue, but affects those who either choose
to use an 'old fashioned' dialup - or who have no choice. As you say,
though, using systems that aren't what most people are familiar with
does tend to bring more awareness of these issues.

Slainte,

Jim
