Hello :-)
Sorry, too much work this week !
You know the price for 6H30DR 3 years ago was much lower than today, but I'll check soon when I receive the 6C4P and open the Ayon :-)
The DR version has a little more of everything, that's the way I would describe this tube, compared to stock 6H30, it's not a complete change (which would be surprising) but just an improvement. With some resolving systems and speakers, this becomes more obvious, lower details rise from the background and the shape of sounds is more defined with better dynamics.
Tubes to my experience (at least for preamp tubes) are OK after 50 to 100 hours, they can improve a little more untill 200 hours.
Unfortunately even with shielded cables I have problems with XLR connection, whatever is the input impedance of the amp. So I use RCAs, it's OK, if necessary I can use the small SPL Volume2 as XLR preamp/volume control, it solves the bug (which is surprising also).
