Hi David,
Thanks for the information. You have cleared up a question I had
about the differences between the Aleph 3 and the newer iteration, the Aleph 30. There has been so much written about these two amps! It now appears that the company that actually manufactured
the Aleph 30 with (apparently) Nelson Pass's blessings, is out of
business(?!?!). I thought they were selling well.
It is amazing how many serious music lovers have deep
respect for the Aleph 3, and still love it as their amp of
choice in their systems.
I have been visiting audioasylum recently (yes...I know...
whatever must have come over me!) and picked up a thread
about the Carver Professional ZR series of "T" class digital
amps. It seems that Carver Professional uses the Tri-path
chips, like BelConto "digital" amps to perform signal matching
between the incoming signal and outgoing signal to make
certain they match correctly. There rate of pulsing is higher
than the PS Audio HCA-2 which could point to a higher
resolving of the audable signal, although this is not certain,
since in the realm of so-called-digital amplification there may
be a point where more is not neccessarily audible.
On the other hand speed of "pulsations" may become
a benchmark that amp designers may use in marketing
hype, not unlike bit depth in scanners.
If the tri-path chips can control mosfet transisters, which is
what is used in the Carver Professional ZR series, why can't
they be used to control tubes (yes...yes...I am commiting a
grievous crime here, saying chips and tubes in the same
breadth). David Berning, for instance uses radio waves
to "control" his tube sets in his ZH-270 "OTL" amp to great
advantage. Just a thought. But I feel it definitley will lie in the
future as a possible "controlling" factor in tube typology.
More later, my wife wants me to drive her to the Fed-Ex
store...
