Most power amps don't have level controls on them... hence the need for
either attenuation or a pre-amp.
If you have a power amp with level controls, then yes that's fine.
Even if you've got attenuation set (by whatever means), you have to be
careful with test

I'm doing some tests on Ripstation now.
Yes, Linn promote it (but that's because it's very easy to use) - but
on their website they refer to EAC as the gold standard...
OK - here's a quick test:

Thanks for the link - and the quick test report. Indeed, the batch
approach of RipStation is an interesting feature - really.
I learnt a thing about AccurateRip and its confidence level. Is there a
maximum level ? Another question concerns the checksum I reported
previously : EAC and dbPowerAmp

You want to see the signal path BEFORE it gets onto a CD/vinyl...it
ain't what you'd call minimal...

GT2 cables are terminated with 24k gold-plated USB 2.0 connectors said
to improve grip and to keep mechanical and electrical distortion at
bay.

OK, I can confirm I give up. XCFA (cdparanoïa) and RubyRipper
(cdparanoïa plus specific algorith, extraction is made twice and results
are compared) gave me differents results (in the sense : FLAC audio MD5
checksum), between them and between EAC/dbPowerAmp or RipStation Micro.
I still think
Cliveb is right
Clipped midrange / bass frequencies, tend to produce square like
waveforms, therefore from Fourier Series, must contain significant high
frequencies. Many loudspeakers, even supposedly high power only have 6
watt rms handling tweeters. Also some specialist designers run

Of more importance in this context is the approximately square wave
nature of clipped signals - DaveWr has already explained that.
I suppose the flat-top of a clipped waveform can be considered to be a
momentary burst of DC. If it was

Mike, thanks for the link. The best thing about this article is how it
gives USB cable the full audiophile treatment and even as goes as far as
ascribing a sonic character to the cable. However
The connector and voltage for the Touch is identical to the SB3. If you
have a bus powered USB device plugged into the Touch (such as a USB hard
drive) it can draw more current than an SB3. So a linear supply that has
more than enough current capability for an SB3 will probably run the
Touch with
