Thanks for the article, great info. Are there any considerations that
need to be given to the power amps rated input impedance vs the
Transporters?
for instance I am considering an amp. has an input impedance of 10 ohms
(so says the spec. sheet) but it doesn't give the input sensitivity...

I hope this isn't off topic, but something I noticed on the Rothwell

the preamp had an analog volume control?
Maybe the reason it seems on-topic is because of the

Great idea and post. I am currently checking out new power amps and
speaker combinations so you timing is good.
My Transporter has the three built in attenuation levels on the
unbalanced outputs, can you add some information on what the output
levels would be at each of the settings?

Hi Eric.
If you read the references, in order, they all lead up to making the
last one seem outdated (it's almost 2yo). E.g. the volume control in
the DAC *is* used now, which is precisely the point of the more recent
link directly above it.

I will probably create a ConnectToPreAmp page too to discuss that issue

This would mesh perfectly if you turned analog point 10 into a big
hyperlink like I did with points 8 and 9.

nice work... I think the only point I'd want to debate is your
assumption that we don't need to cover the Transporter as their owners
are unlikely to be beginners: not beginners in audio, almost certainly,
but could easily be complete novices in slimserver or computer based
audio.

Absolutely, as you indicated, it's a wiki.

My understanding is that PREAMP volume control is implemented in the

Yeah I shouldn't have used that example. The more contradictory thing

One minor point - somewhere in there was a link to a post by Sean Adams
where he states that each level on the 100 point volume scale is a dB.
I think it's .5 dB actually, and IIRC he corrects himself later in that

Good job, something like this was needed. Unfortunately they will still
ask how to hook up and use integrated amps/receivers, especially the
volume control.
I would also point out that the opening line reads like a poor
translation:
