The Siemens is similar to the Tele except is has a touch more magic in the midrange vs. the Tele.I found the sound I was looking for in the NOS Telefunken (see post #34 in this thread). This tube pulled things together for me with the La Scala. While I still own the La Scala I rarely use it anymore, now putting my focus into the Lampizator Golden Atlantic TRP3.
What do you like about your Lampi vs the La Scala?
