Anyone try the "Polk Audio Monitor 10, RTA 11T Upgrade Kit" listed on eBay?

A B&K ST1430, but it is irrelevant. If the caps were coloring the sound, then the two would sound different when driven with identical amplification, regardless of the identity of that amplification.

1) Subjective
I have two sets of speakers which use RD0-198 tweeters. One has Gen 1 Sonicaps in that portion of the crossover while the other has 5% tolerance Daytons. The highs the speakers produce are, to the best of my ability to hear, identical. Obviously a highly unscientific test, but enough to convince me to purchase Daytons for any future crossovers I want to recap.

2) Objective
What exactly is the difference between a Dayton cap and a Gen 1 Sonicap? They're both polypropylene, or am I mistaken on that point?

1) If you think they sound the same, they sound the same. However, a good number of folks have found otherwise.

2) Different methods of winding, different grades of materials and different thickness of materials all add up to sonic differences in poly caps.

I think we've been back and forth over the baseless accusations of trolling and can safely retire them. In fact, in this case I would suggest that unless YOU can make a positive contribution here, just be quiet. In connection with capacitors and cost, I am looking at a series of high-precision measurements I just made on nine different 8.2 uF capacitors:

'Bennic XPP ($4.05)',
'Erse Pulse-X ($4.27)',
'ClarityCap ESA ($25.65)',
'ClarityCap SA ($12.80)',
'ClarityCap PX ($6.15)',
'Jantzen Cross-Cap ($5.35)',
'Solen ($5.73)',
'Sonicap ($15.60)',
'Dayton MPT ($3.37)'

The most accurate capacitor in terms of MEASURED CAPACITANCE (10Hz-20kHz) was the Jantzen, and the worst was the Sonicap. The Jantzen absolutely trounced the Sonicap for about 1/3 the price. If somebody would like a plot of the results they can PM me. Solid data like that is wasted on subjectivists who buy capacitors based on price, appearance, and the testimony of loons.

The most accurate capacitor in terms of MEASURED CAPACITANCE (10Hz-20kHz) was the Jantzen, and the worst was the Sonicap. The Jantzen absolutely trounced the Sonicap for about 1/3 the price. If somebody would like a plot of the results they can PM me. Solid data like that is wasted on subjectivists who buy capacitors based on price, appearance, and the testimony of loons.

The problem with data is that it doesn't tell you how it souinds. If you had used your ears instead of that void between them you would realize that the Jantzen's don't sound all that good. Sadly, a putz like you will never get that.

Do capacitors have some magical property other than capacitance? When a capacitor is labelled as 8.2 and it measures 8.0, is that good as long as it costs alot?

Oh, and the more you call me names, the more you come across like a coward.

OMG.

It's audio guys, it's not THAT hard. Why you all can't get that boggles my mind. Is anyone listening to music anymore? Buy it, don't buy it. Take the advice, don't take the advice. For the love of music, drop the f'n needle, close the drawer, or start a playlist already.

This tube, that tube. This cap, that cap. This cable, that cable. Flip the switch, twist some knobs, and SIT DOWN. God almighty.
