I have repeated ad nauseam on this and other forums that good, clean power and "taming" vibration and resonance unleashes the full potential of any hifi installation. No need to upgrade until the very basic premises on which good hifi rests are fully implemented: (i) good, clean power and (ii) vibration and resonance mitigation.

10. Replaced the resistors on the Alexia Vs.

Why there is the need for replacing them in the first place? Totally irrelevant.

This is OT but since it was raised above.....
Replacing the outboard Vishay resistors on the Wilson speaker crossover for the Alexx V and some of their other speakers (Alexia V, XVX) once a year or so (depending on how often and loud you play) is a very real observation and recommendation by Wilson. The obvious question is, if the resistor isn't blown, why does it need to be replaced? The answer is- I have no earthly idea but it's an important thing to do- it matters sonically. I've had discussions about this with some of the Wilson folks and can't say I was impressed by their answers, but I can't disagree with the sonic benefits of changing the resistors. It's a few hundred bucks for very tangible benefits. Just do it! You will likely find the speaker sounds a bit smoother in the upper mids and highs when the resistors are changed. My preference from my crossover building days would be to use identical value Caddock 311 series resistors that don't depend on the heat sinks currently utilized for the current Vishay resistors, but I haven't succumbed to temptation yet and probably will not. You can bet however, that Wilson is probably going to move to different crossover resistor technology in future models. There's nothing sonically wrong with the current configuration but it would be nice to find resistors that don't require recommended yearly replacement.

All resistors degrade over time. I think this is a neat solution to keep things fresh.

All resistors degrade over time.

^Ok^… how?

I think this is a neat solution to keep things fresh.

Most resistors are not hydroscopic, are not
Oxidising, and are not corroding.

May I ask a question?

Have you tried less expensive LAN isolators not necessarily suitable for streaming in front of things like tv set, home office computers?

My streaming comes from a Fritzbox router to a Taiko router, etc.
Fritzbox does feed from other LAN outputs tv, madame’s home office computers and other appliances.
Putting an otherwise pretty decent Ediscreation switch between Fritz and non-hifi appliances improved tv picture, but surprisingly hurt music.
This was several months ago, my system has been moved to another home, a lot of grounding stuff has been introduced (CADGC1, 3, usb control, Groundarays …). This might come out differently today.

Would, say a measly delock, an ifi LAN silencer, DX iso-plus, all for small coin, help keeping noise coming from tv, etc. away from our music?
Put them at the non-hifi outputs of the ips Fritz router?

Cheers and thanks in advance for your help!

interesting question. My TV, TV box and router are powered by equitech balanced power gear. When I was waiting for a demo switch to try at that location (different room from hifi), I decided to break in a power cord using it to power the equitech so that it would be ready to use when the switch arrived. I'm not sure if the TV looked any better, but the hifi sounded better. That was completely unexpected. My assumption is that even though the hifi is on a dedicated line, everything goes back to the breaker box and cross contamination happens there. So, if the nice power cord is a two-way filter, it is partially reducing the noise from the three noisy components going back to the line.

That has me thinking about trying something like this which is designed to reduce high frequency noise: https://jaguaraudio.com/product/akiko-triple-ac-evolution-by-akiko-audio/ It would share the outlet with the equitech. $525 isn't small change but compared to some of the gizmos I've tried, it isn't unreasonable if it works well (and try-before-you-buy opportunity).

Hi PYP!

I did a similar approach.
I use my old mains filters which I don’t want to have in my hifi setup anymore for tv and home office pc.
I haven’t done comparative listening, but this certainly helped ocd regarding mains pollution

Just curious: What do you power with the Stromtank?

 

[engadin]

Frontend, preamp.
Not amp, not subwoofer.
