Last night I dealt with the new tubes in the LP2030.
WOW, parts.
The Arcturus are a dream. high resolution, great timbres deep tight bass. wide stage but exact assignment.
The de Forest sound very similar, but the stage is a bit smaller and starts a meter earlier.
Ultimately, a matter of taste, both a stroke of luck.
Only one thing I noticed.
all globe shape types I've tried, Ken Rad, Sylvania, Cunningham, Philips, etc. Do not hum or buzz when the pre is fully revved. for this they react to impact sound and touch.
With the ST types it is exactly the other way around. slight humming in the loudspeaker but shock-resistant.
I have a pair of Ken Rad 71a ST which can do both, no noise and not sensitive, but the stage is a bit smaller.
In the end, I can live well with all combinations in the pre amplifier, bad ones don't really exist.
it's more a question of optics, what you like. Globe, ST, the glow of tungsten wire or the simple version without. the blue of the Arcturus or the small nipple on the de Forest. all nice to look at.
Sonically, almost all tubes in the LP2030 that I have tried can be classified as equivalent.
The differences are if at all so minimal that they will not be noticeable in some set ups.
It is rather worthwhile the tube rolling in the Power Amp, here the differences between different drivers or rectifiers are much stronger.
