Monday Funday
I got to put the Siemens EL34s in today. They sound, as expected, great in the HX/DA. They are NOS, so I am going to use them for a bit and let them wear in some. They look to be very well constructed, as I've come to expect of most electronic things made in Germany.
Early impressions are very good, comparing them with the Winged C EL34, which is high praise as I consider the Winged Cs to be the best sounding guitar tubes made over the last 30 years. As far as I know, neither of these are currently made and NOS or used is the only way you're getting them now.
Where they are similar: Quality of the sound, plain and simple. They never seem to be out of control or on the ragged edge. No matter how hard I push them in this amp, both retain a good tone and sound as though they could do this for weeks on end. The drive tones are especially lively, and have a dimensional character that kind of makes you want to play them loud. I especially like that neither sounded buzzy, fuzzy, or thin. You know how some amps start to sound like paper tearing when you crank them up? None of that here.
Where they are different: While either will do a bit of what the other shines at, they
are different. The best way I can describe it is to say the Winged C is classic Plexi, full of controlled top end that has that great sizzle to it. The low end is there, but it's those sweet mids and highs that you notice right away. The Siemens, on the other hand, has a slightly cleaner and tighter sound, especially in the bottom, that sounds authoritative. They have a punchiness that reminds me of a cranked Hiwatt DR103... a real ground shaker. Like the Winged C, it never sounds like it's breathing hard.
Conclusion: I now, finally, have a tube I can feel as confident in as the Winged C EL34. I'm going to add a few more pairs to my tube shelf while they can still be had for a decent price. At this moment I am not sure which set I'll leave in, and that is not something I have said since the 90s when I started using what was then called Svetlana tubes. Each set makes me want to play a bit differently, and I am enjoying both. If you haven't tried the Siemens tubes, and you're looking for something to tame a raging EL34 amp without sucking out its soul, this might be the ticket. They are some of the more
musical EL34s I've heard.
Thanks to
@LSchefman for the tip! Now, on to preamp tubes...
