i'm using a passive line level xover (between pre & amps) to drive
my maggies 1.6 directly from my amps; the high pass filter is this:(xo point: 600hz): 5k49 in series, 4k53 in parallel, 2n2 in series
i recently replaced the 5k49 vishays s102 by 5k6 audio note tantalums,
1 w, with the following clear results —no "it seems...":- more full-bodied sound, which is very nice in the highest highs
- deeper soundstage
- more cohesiveness & musicality
- more smoothnessso i've to conclude either that the tants are more transparent
than the vishays (at least for the mids and highs), or that there is a
special synergy between them & my 2n2 jensen copper foil/PIO capsthat said, this may be true just in my system, for my music and
to my taste and ears, as alwaysbest, paco

By the why what tants did you use. I replaced just one in my pot and found as described nicely by you that the tants are very nice, though i found them a bit bright compared to some carbons(can't recall brand, but of good quality.Did the bass suffer in comparison to the vishays. They did so with the carbons.
as said in my post, i used 5k6 audio note tantalum, 1w;
i found that they are still less bright than the vishays,
but with more life and more natural soundtants are believed to have the bass flawed, but i'm
using them just for my high pass filter, so anything
under 600hz is irrelevant in my case!!best, paco
If you like the Ta's, try a pair of Rikenohm carbon films, available from Angela Instr. @ about 1/3 the cost of the Ta's. To my ear the Ta.s are thte 2nd best sounding R now available, being bested noticeably by the Rikenohms.Happy listening !
Paco, did you notice more in the way of up-dowm imaging with the Tants than with the Vishays? That took me a while to figure out as I knew I didn't like the Vishays, but had a hard time putting my finger on the reason I didn't like them.....
hi Bob,you are right!, i've listening to the tants for a few days,
and, although i already knew i liked them much better than
the vishays from the beginning, it was difficult to describe
the reasons why it was so; when you biamp maggies, the soundstage
is so huge that noticing differences in the vertical size of
images is hard; instead, i'd perhaps say that images have
more spatial volume and mutual cohesiveness...best, paco
The only problem i had, with the Shinkoh used as a series resistor (10k) in a shunt attenuator, was that they sounded big, but much too soft in the bass, they 'acousticized' and somewhat homogenized all bass sounds IMO - i could not live with it. This bass 'colour' was for my ears a clear loss of information and bass impact.
However, a friend who is using this 'multi-brand series resistor input shunt attenuator' now prefers the Shinkoh on the whole.
please tell us more about the difference between the Tans and the s102.Thanks

Hi Pat,I can't tell you more as I have not tried the tants at all, but am familiar with the problems of the Vishay S102s compared to the Caddocks, Holcos and Resistas as well as some others that didn't make the final cut....
dear rcrump,I am planning to use some good resistors for the signal path in the amp. I've already used Riken (0.5W and 1 W), Kiwame (2W) and Mills (5W and 12W) in my amp. But for signal path, I would like to try something better.
I have 12 resistor in my signal path (6 for each channel, then 3 for each tube in one channel), so buying 12 Vishay is quite an investment, so I would like to know your opinion on what resistor to use.
I've seen +ve and -ve opinions on Vishay S102 on the AA, but no one is conclusive. Same with the Tans.
Thanks
Pat
I like .5w Resistas primarily with a smattering of .5w Holcos just to warm things up a bit, say for feedback....The Caddocks don't focus very well and the Vishays don't image correctly, but are squeaky clean so pick your poison, but you can't go wrong with Resistas with a touch of Holco.......Power supplies love the Resistas BTW.......The Resistas will only work well when the power supply diodes are soft recovery types as they are bright otherwise.....Vishays have their place as do Caddocks, but not used by themselves in the signal path......IMHO, of course.....
