Digital amp beat them all? Audio Physic Strada .

Rockhead has a good point, just as in other technologies people will prefer one appraoch more than another. This is even more of an issue with what a new (in the big picture of things) approach. While it may not be perfect (what is?) I can't help but believe that there is great promise here (perhaps more so than in any other approach). Next digital cross-overs. Marakanetz, thank you for your explanation, your opionion is valued.

A few corrections.

RIAA equalization has been in use SINCE the 1950s. I believe it was established as the standard for the modern 33rpm LP.

Upsampling will make no difference to bass .. its aim is to ease the implementation of the brick wall filter which prevents aliasing distortion, according to Nyquist's theory of sampled signals.

The mechanics of sampling and quantizing a signal introduces quantization noise and limits the upper frequencies (due to aliasing distortion) but it does not selectively remove details or harmonics. Digital equipment also has practical limitations (jitter, DAC non-linearity) which are worth discussion.

In summary ...
We all have a preference for the sound of analogue or digital .. personally I like both in different ways, at different times and in different moods. But please, don't pretend you know what you're talking about technically when you clearly do not. It helps nobody. DOes anyone have a link to how digital amps work ? I'm interested to know.

Whatever there are pros or cons about digital amps/preamps, I'm damn sure that this new high-tech is now mega-overpriced and in most of the cases still "factors out" leaving one on the nominator and the classic analogue amps/preamps in denominator.
Do your algebra instead of reading or listening to the reviews and factor out extra zeros :)

Well Dinos .... you question is answered. There will be much resistance due to the general hocus-pocus explanations of why digital must be bad "and so I won't even bother to audition" attitude.

For me I'd rather get a $1k integrated and pay off the house ... so it will have to get a lot cheaper. But I'm very interested in it. Audio Physic has a good reputation to lose, so I'm sure they've researched it.

I´ve heard the arguments before!There has to be ...because
..To be more specific: there is an audio society here in
Sweden called Ljudtekniska sällskapet "The society of sound technique". Their guru often has some splendid explanations
of why products have to sound in a certain way, even before
he seems to have listen to the products in question.
One member thanked him, because "before, I thought I heard
that SACD sounded better than CD, but after talking to
the (name of the guru),and after getting his technical explanations, I realised, that I was totally wrong!"
The question: are the Stradas overpriced or not, can not
be easely answered without a general discussion of the whole
audiomarket! To me, quality of components in an amp,the
built quality, the efforts and intellectual challanges that
are laid down in a certain product; these factors play a
great role.Please note, that digital amps can be realised
in different ways, and that the Stradas doesn´t use
the Tri-Path building blocks, used in several other digital
amps.
I´m not trusting magazines that much, but their findings
may or may not have significance to us, as consumers. That
is our own choice.
I´m not saying that the Strada monoblocks are splendid
products,because that I don´t know. Certainly they are not the end of the road, but I find them interesting enough.
