just listened to the siemens df91 - siemens dl92 combo:
this is by far the best one manufacturer combo:
if the analytical valvo - valvo combo sounds like a 'domina' and you feel a little forced to listen to and being penetrated by the music, the telefunken combo says 'you can listen to me, that is the sound, enjoy it or not', and the lorenz - philips combo just let you sit down in the armchair at the fireplace, offering you whisky and cigar, putting your shoes off saying 'relax and dream, feel safe and comfortable, don't think of anything, enjoy the music, we take care of all the rest', the siemens combo is just between the telefunken combo and the lorenz - philips combo.
listening at moderate to higher volume you feel actively invited to listen to the music, actively selecting and listening to a great presentation, lots of detail, realistic soundstage, it's more like riding a horse than watching a movie of that. i find the siemens combo much more enjoyable than the telefunken combo.
if you listen at lower to moderate volume this combo is nearly as relaxing as the lorenz - philips combo, you now see the movie, not actively riding the horse, just watching and enjoying.
siemens df91 - philips dl92 combo:
with the philips, bass weight and texture is improved, a part of that swinging sound i love the lorenz - philips combo for. interestingly i feel that the siemens - philips combo sounds slightly warmer than the lorenz - philips combo.
back to the lorenz df91 - philips dl92 combo:
the lorenz adds this magic sweetness and swinging micro details to instruments, strings, voices, so together with the bass texture and weight of the philips this is really the dream team!
a short summary - related to only my tube collection:
the philips dl92 is a must in my tube collection and is available in the market.
the lorenz df91 is a dream if you get one, sorry two!
if you have a slightly warmer or neutral headphone the siemens df91 - siemens dl92 combo is easily available and (more than) worth a try!
if you have a neutral to slightly brighter sounding headphone, the siemens df91 - philips dl92 combo is easily available and also (more than) worth to fill the gap until you get a lorenz df91.
Fascinating insights GG. I agree, the Phillips brings extra weight and texture and I think this is why it is such a perfect pairing with the Lorenz. I would agree as well that the Siemens/ Lorenz combo on reflection is slightly warmer sounding, though I think instead of warmer, perhaps sweeter. The Siemens are a "sweet" tube where as though the Lorenz is sweet also it has a little more "bite" to it which allows one to discern instrument placement a little better and I feel give a slightly more accurate picture of strings texture and type(gut, steel, nylon), that added detail you talk of!
I agree as well, the Phillips is a must and thankfully easily available and as I have said before, pair them with Siemens or Mil-spec Sylvania's and you come within a hairs breadth of the Phillips/Lorenz combo.
All these wonderful thoughts have made up my mind to plug in the Marconi's later today. From memory they add a touch more "air" to the Phillips/Lorenz combo whilst not losing the underpinning!
Have you found what I find that the "thicker, deeper" tubes such as the Phillips sound better in the 3S4 stage? I have Mullards from the same factory as my Phillips and putting them in the 1T4 stage and a lighter tube in the 3S4 stage does not give as satisfactory a result as it being the other way round!
