i think i start to get ill, infected by the tube rolling virus, so here are some very preliminary impressions:
valvo df91 - valvo dl92:
if the lorenz - philips set is homogenous, this set is analytical like listening with a magnifier glass used to see every and i mean every detail, less bass and bass texture, not so relaxing to listen to, really pronouncing the highs up to a level near to call the sound harsh, but with absolutly precise not to say hard attack. could be a great set for warmer sounding or how to say slower headphones. slighty miss soundstage depth, but no burn in time for the tubes.
valvo df91- philips dl92:
sound stage depth is back, also the bass weight, but not the perfect match and magic as when listening to the lorenz - philips combo. not pronouncing the highs as much as the valvo - valvo combo, but adding some nice sparkle to the highs, worth a try.
lorenz df91 - lorenz dl92:
interestingly pronouncing the bass more than the other combos but at the same time sounding unprecise (the word bass porridge came in my mind). not recommended.
back to lorenz df91 - philips dl92:
all the magic is back, you stop thinking and start listening. can't really explain it completely with words, but up to now this for me is the dream set made in heaven.
p.s. please be sure that i will not stop looking for lorenz tubes until found them!
