Digital amp beat them all? Audio Physic Strada .

The german magazine Stereoplay has(in its June issue) a review of the new Audio Physic Strada monoblocks.
Like most german audio magazines this has also a preferance for ranking products in a hierarcic manner.
Interestinly, the new monoblocks from Audio Physic gets
60 point (on a scale that end with 63 points), while the
mag´s former reference Krell FPB 650 M gets 59 p.
For your knowledge;Electrocompaniet Nemo gets 58 p, the same as Pass X-350.
Althought the fact that I am sceptical about ranking systems
in Audio,I find it remarkable that a digital amp allready
can compete with some of (what is regarded) as "top-flight"
amps!
The Strada monoblocks has a switched powersupply and some
innovative curcuitry,e.g. it seems to be handling signals
of low amplitude in analog way, and switches over to digital mode for higher amplitudes in some form of bridge
output section. Sorry, my understanding of technical german
isn´t splendid.
They deliver 255 W/each in 8 Ohms, and costs about 15000 Euro a pair.
What do you think? Are digital amps taking over the scene
in the years to come, or will there be a "resistance movement" corresponding to that of CD-anlog?

Vinyl and 8 Hz reproduction? You get serious problems with
warped records, then these sub-frequences, if sent further
up the chain, will charge your amps in vain,and your woofers
will flutter.Marakanetz it´s a good idea, to adjust the
weight of the cartridge, its suspension, and the mass of
the arm so that sub-sonic information (low frequency rumble
and that of warps)form a high-pass filter . This was shown
several years ago, I think in the 70´s, by a dane named
Paul Ladegaard.Like Unsound, I think you have come a bit
off target!And the frequency respons curve in Stereoplay
shows that the Stradas are only down by a fraction of a
dB at 10 Hz. Their subjective bass reproduction is said,
in the review, to be better(lower, with more grip and with
more corpus)than any amp tested before, including Krell
FPB 650 M.

Sorry, correction;should be:to adjust or match the weight of the cartridge,its suspension,and the mass of the arm, so that they form a highpass filter, that rejects low frequency information like rumble and signals from warped records.

The comment about Audio Physic Strada was that they deliver:

255 W / each in 8 Ohms, and costs about 15000 Euro a pair. What do you think? Are digital amps taking over the scene in the years to come?

How about this amp which is already here!
206.5 W / each in 8 ohms
Distortion 0.1%
Freq. Response -0.08 decibels 10 hertz and 20 Khz.
THD less than 0.037%

This second amp appears to be very close to the Audio Physic, and COSTS WAY LESS.

And which amp might that be Albert? Inquiring minds are dying to know!

8Hz is away from the cutoff ?? What cutoff is that ? The only cutoff I am aware of is at around 20kHz for the anti-aliasing filters. I'm not aware of any low frequency rolloff in the redbook standard. I'm getting tired of these half-truths. By all means describe what you hear, but leave technical explanations out unless you really know what you're talking about.
