1.6 passive line xo further upgrade: jensen did it again!

62.42.63.20

as posted before, i've been experimenting with a version of
Davey's passive line level xover in biamping my 1.6 for a while;
a few days ago i replaced the former caps in series with my
tweeters (polystyrene rel-cap RT series) by jensen copper foil
paper in oil; after critically listening to a lot of music, my
results are as follows

the music now flows in a more natural way than before, with
a lot of "bloom" thoroughout; there is a clear improvement in
resolution, then in palpability, inmediacy & low level detail;
decays are longer and ambience & air are impressive when recorded;
the soundstage is clearly fuller and better articulated;
individual images are fuller and bigger in size, so even
small instruments, with less harmonics, say violin or lute,
now sound more musical, then more believable & enjoyable;
more complex keyboard instruments (piano, harpsichord) seem
to provide you with a full symphonic concert by themselves;
organ is now sounding even better, for although the bass was
before already very good, now the midrange texture and the
highs are more natural; string quartets are now MUCH more
musical, mainly because the midrange has become "magic" (this
is usual with jensen caps) and the highs are much more fullbodied;
vocals sound clearly more human & involving, and even not
particularly good tenors & baritones sound more palatable;
grand symphonic orquestra & chorus sound even more spectacular,
due to the higher resolution; finally, jazz & pop & rock are
more enjoyable than ever before, being this particularly true
with highly distorted electric guitar, which is sounding me
even "musical"! in a word, warmer treble & magic midrange in a
much more musical general context

my circuit is now as follows:

high pass: 5.49k ser (vishay) - 4.53k par (caddock) - 2.2nF ser (jensen copper/pio)

low pass: 5.11k ser (vishay) - 68nF par (relcap) - 49.9k ser (vishay) - 22nF par (relcap)

further upgrade? hmmmm... i think i'm done, but i may try
a couple of those tantalum resistors later on

hey guys: if you want to listen your maggies 1.6 to their best,
passive biamping is the way, and i assure you i know what i'm
talking about, after having been tweaking my pair for 1 whole year

i hope to be able to send Mart a final section for my mods
page on biamping soon

best, paco
