I had my X-Can V3 modded by PinkFloyd back in May of 2006. I have gotten many hours of happy listening since and wholeheartedly recomend it. Recently I had added the Little Pinkie PSU and it helped bring the X-Can V3 to a new level. Everything was happy until I picked up an used X-Can V2 and sent it to PinkFloyd to have the "Full Monty" done to it including another Little Pinkie.

Well by this time PinkFloyd had developed a new mod which exchanged the regular rectifier diodes (1N4007) with ultra fast diodes (UF4007). This reduces the recovery time from 2000 nano sec to 75 nano sec. Here is a picture I borrowed from PinkFloyd's website:

The V2 is sounding so good I was considering selling my V3. Well PinkFloyd sent me a set of 7 of the above mentioned ultra fast diodes and I finally got arround fitting them to my V3. This was an ordeal since I have not soldered anything in 12 years. Well here are a couple of pics of the before and after, just click on the thumbnail to view the full picture.

Before mods:

After mods:

The change these 7 ultra fast diodes have brought to the V3 is amazing. The clarity and air you can now hear in between notes is nothing short of mind blowing. I used to state that the V3 had beautiful detail, although correct it has gotten much better and this with only 2 hours of burn in.

I do not know how much these parts go for specially with the exchange rates but if you have a V3 or a V2 I highly recomend you take the time to fit these in. Good luck.

You got that right! It's like adding a stargate at the headphone jack!

What's the link for PinkFloyd's website? It's a little difficult to find with a Google search, something about the name, I believe...

Hmm. I see that the UF4007 is generally available. Do you think it would be a good idea to use them in other amps, not just the X-Can? If so, it'd be little trouble to put them into some of my projects.

It's about 50 cents for each diode+cap, so $3.50 total.

I'm so temped to get an Xcan3 & have you mod the crap out of it..I'm going to audition the Caynin 1A headphone amp next week, to see if I like the tube sound..

Can someone spec the snubber? The UF4007 is $.18 at Mouser (at most), so I'm also curious if this is applicable in all circumstances, particularly in my electrostat PSU where there are 8 1n4007, or, in general if the UF4007 is universally better?

I could always bring mine out to you and you could give it an hour or so, it may cost you a meal!

Different diodes can impart different results. I have used ultra fast soft recovery diodes for a long time but of the more expexisve variety than mentioned here and for a much higher voltage, since that is what I was working in. A good diode that does not impart a sound of its own on the carrier signal being used for the AC musical signal should be good in most situtations as long as the supply it is working with is stable.

It works wonders in V2, X10, with X-PSU

I spoke with some tech friends about the cap and they all claim a ceramic would work just fine. So I got the diodes for $.07 and the caps for $.03 from the ol surplus shop. caps are .01uf.

That's Keeley Hazell. Just do a search on her, she's all over the place...literally.
