Hi, Isaac,

Interesting analogy.  To tell you the truth, my ears have never 
experienced the "vintage" 300B tubes, and my gear is now a Quad77 
solid-state amplifier.  But I know that I enjoy "recorded" music the 
best with a tube-amplifier one of my friends made.  I am not sure if it 
has 300Bs.  This may be a repeated topic in LUG, but I do think that 
high fidelity and good (comfortable) reproduction are not always 
accomplihsed at the same time and that it seems be also the case with 
photo equipment.  Yes, I see such double accomplishment in 75mm Summilux 
(a little less in 50 mm Summicron). I am now very much interested in 
Summilux 35 mm non-ASPH, which is adored by some but exchanged without 
slightest hesitation with the ASPH version by others.  My Summicron 35 
mm ASPH is stunningly HI-FI and appears inorganic but, fortunately, in 
an agreeable fashion.  My two cent-worth impression.
