Bypass capacitor questions


I have built new crossovers for my Thiels using mostly Clarity CSA caps. On the coax board, the two feeds and subfeed are bypassed with Multicap RTX (~1%). I am super happy with the SQ improvement. Well-recorded music sounds fantastic, just sublime. Really hard to fault, especially at this price point. Excellent transients with resolution and transparency for days; adding the RTX added a bit to the transients and resolution. But poorly recorded music is now more evident than ever and can sound relatively "cool", even thin, most notably on vocals. I’m wondering if a double bypass or different bypass cap might add a bit more flesh or hint of warmth. The Jupiter copper foil at 0.01 uF caught my interest but I’ve read reports that this small of capacitance can be inaudible, as well as reports that it can make a big difference (eg, humblehomemadehifi review of Dueland bypass).

Two questions:

a) do you think a different bypass or double bypass would result in the sound I seek?
b) if yes, more likely to get a good result with Jupiter double bypass at 0.01 uF or, say, Audyn True Copper Max at ~1%.

Budget: something more affordable than Duelands!

Remove the bypass caps.  Only bypass in power supplies not in speaker crossovers as the results are oftentimes all over the board and impossible to predict.  Bypassing in crossovers makes the sound phasey and not quite right. 

Also look to the resistors.  Remove sandcast and replace with Mills MRA.

That was *not* my experience. I heard sharper transients and a tad more resolution with the RTX.

The first change I made was replacing the sandcasts with Mills MRAs. That was a really nice improvement in SQ for short money. So much so that I'm curious to try a Path Audio resistor in a key position.

Thanks for the responses everyone. I think I will stand pat for now. I mean, I'm *very* happy with the sound I'm hearing. Easily the best ever in my room. Just with the downside of TMI on poorly recorded music, a problem Michael Fremer and others have complained about with some speakers. But, honest reproduction of the recording is a "problem" I'm happy to have.

@teo_audio, very interesting information!   I'm going to apply it in my next high-end audio crossover build. 

Suppose you have a situation where you must use multiple capacitors to arrive at the desired value.   Based on your comments, I presume that using multiple identical-value capacitors, where possible, would be the best approach?

Sharper transients is your phasiness rightbthere. I think several of us are willing to bet $ you will pull it out eventually esp if you listen to classical music.
