Hello,

 

I am thinking about upgrading the fuse in my Keces P3 too. I have checked the rating of the fuse originally installed in it, and it seems a T1.0A  type (it is hard to read).

Which type/rating fuse did you replace it with? Was it the SR Blue?

 

Thanks,

Zsolt

 

 

Hi

 

If you are not sure about type and rating of fuse, I will first contact the manufacturer before experimenting with aftermarket fuses. For safety reasons, you don't want install wrong type and amperage of fuse.

 

I can recommend SR orange, if your funding let's go. Like them in every component I installed, JS-2, dac, even headphone amp.

I agree on SR Orange.  The problem with SR fuses though is that sometimes you need to go to the next highest power rating to ensure that they don’t blow when a component is first switched on.  Best to also check with those who have the same component.

 

At one point I swapped all my fuses with SR Blue.  My preamp and amp were fine with the value specified by the manufacturer.  My phono stage blew the fuse on power up though due to the inrush of current.  I was fortunate to have a dealer who allowed me to swap the blown fuse for Blue of a higher rating.

That is true, SR fuses are famous to unreasonably blow up during powering on the device, especially on tube components. I have moded tube dac and have to settle up with double amperage, to stop blowing up the fuse. Good think that was happening during satisfaction guaranteed 30 days warranty and do not have problem get replacements.

Hi, the Keces P3 is sensitive to the fuse.  Per the manual 'Fuse : 2A fuse for 115V / 1A fuse for 230V'.  I'm using a 115v and can confirm a 2A small/fast blow (F) fuse was in it.  I'm guessing you're using 230v.  With SR fuses you want to go one notch up, so I use 2.5v to avoid blowing the fuse when switching the unit on.  The stock silver/ceramic is a little unnatural sounding on the treble and a few reviews have noted that in comparison to the Sbooster.  The blue fuse corrects that and provides a very large jump in sound well worth it's price, especially if they're on sale for ~90 USD.  My only issue with the Blue fuse is that everywhere I've heard it, there is a certain coolness/dryness in the upper frequencies that always present.  To me the timbre is off, as the blue fuse imparts a slightly artificial character.  Yesterday though, I heard what the orange fuse can do (though not on the Keces).  It has a much longer break-in period and can sound off at first (dull, too warm).  The orange is more realistic and natural sounding.  It also really cleans up bass <40hz.  Personally, I'm waiting for another 3 for 2 or 30% off sale and will pick up a few of these.

Just a heads up, I’ve  been told that Synergistic Research will be offering a Orange fuse special  in August, buy two orange fuses get the third one for free. I plan to take advantage of that. 

[so-no-mah]

The Synergistic Orange fuses are really special, so by all means get them on special!

Where are these sale promotion going on or coming from?

[kzs70]

Thanks everyone for the Keces fuse recommendations!

I just received a confirmation form them, it is indeed a 1A 230V fuse.

This August special offer at SR sounds good,  if that happens I will buy some more for my amps too...

I'll be interested to know your impressions!

Well I have had time to compare the new Corning Clear Curve with the generic yellow.  Undoubtedly the sound is different.  The sound with Corning is more transparent, the details are heard more clearly and the spatial presentation is better.  Now this is my system, I think because of the cost it is easy to test.  This is comparing both cables in 5 meters.  I have gone to place the Corning of 10 meters to test and I have been surprised that by mistake they have sent LC-SC instead of LC-LC.  I just sent you an email.

Please post part number and link for ordering.  Thanks

For Corning multimode, duplex LC to LC cable:  is Sonore the only source?  $50/meter seems pretty pricey.

Alas, even though I am just across the Bay from FOSCO's facility, shipping is more than the cost of a short link. Otherwise, I might well have gone the Corning route, too. 

 

Thanks to @auricgoldfinger, here is what I am using for singlemode, which was $14.39, delivered, for .7m. 

 

https://smile.amazon.com/dp/B008EN3H0A/ref=cm_sw_r_cp_apa_i_trXhFb11HH700

 

I have no idea who makes the innards, but suspect the product description would have said that it is Corning if it is.  It works fine. 

 

I still wonder about attenuation with these short runs of singlemode, though.  I don't have a clear understanding of when it's necessary (I guess it matters more with certain kinds of SFP's) and what bad stuff happens if you fail to use it when you should (SQ issues?  Burn up your SFP?  Burn up your optical Rendu?).

 

I do recall hearing from Sonore that, even for multimode,they recommended using OM1 cables instead of the OM3 that everyone was using a few years ago with Trendnet FMC's because of overheating risk.  I therefore suspect that I should be paying more attention to temperature than I am.

If you're concerned about attenuation, you might consider exchanging the .7m cable for a 5m or 10m cable.  Leaving the cables wound will provide some attenuation.  The tighter the coil (more bends), the greater the attenuation.  If your system is transparent enough, you may be able to hear a difference between the different lengths.

Thanks again.  That sounds like a smart idea if I am risking equipments longevity by running too hot with the Finisars you guys talked me into getting.

I appreciate the candor. I am so used to every change being described as night-and-day better!

[Mike Rubin]

And I just double-checked the description of the product that I bought.  It also says it’s Corning.  Even though it’s not remotely hidden, I overlooked the Corning reference in the product description.  My bad.

I recently swapped a Sonore opticalModule for the 10Gtek fiber transceiver I was using between my router and the ER.

The 10GTek stuff powered by an HDPlex LPS with an Sbooster Ultra DC module was a definite improvement over an AQ Cinnamon Ethernet cable. Swapping our the 10GTek for the opticalModule and the associated System Optique SFPs and fiber link was a real ear opener.

 

After a bit of break-in with the oM in the chain I honestly feel like I have new speakers!

Thanks Markus,

 

And OT as it might be does anyone know if the UK dealers are honouring the 3 for 2?
