I recommend a very interesting post in the thread about DAP
Cayin N3Ultra, released in April.(~$529)
N3Ultra uses the same pentode lamps in the amount of 2 pieces -
RAYTHEON JAN6418,
which are to be used in May 2024 in the
Astell&Kern SP3000T DAP (~$1500)
The manufacturer's description shows that 2 pieces do not provide a balanced mode, so 4 such lamps are necessary.
JAN6418 tubes are much more sensitive to vibrations than Korg Nutube
and more susceptible to WiFi interference- and this is the reason to get rid of streaming and BT???
(I remember because I had noise in SP2000T at 5GHz).
I am more and more curious whether the noise and WiFi problems that existed in the SP2000T
have been improved in the SP3000T.
Perhaps the 3x higher price gives hope for a more refined DAP.
