Yes they were a bit sloppy in cleaning off flux residue, not sure what type they used but it must not hurt PCB's.  Throws a crazy shadow tho.

I'm impressed with the sloppiness on the botton given the near perfection on the top side.

 

My fan moves enough air to drop the surface temp from 99 to 85. Ambient is 74, all in F.

i stack the PSU´s and the Pre on the Dac with no temperature issues, the may stays warm, but never hot,

and yes, it heats up the XP20 slightly, but also no issues here... Even 7*24, and the result is "warm", but never hot...and i can compare the temperature directly to the XA 100.5...

the left over flux on the MAY Board is very irritating indeed…is this factory style?

Thanks for the picture. I would strongly suggest to rearrange this. While there may not be problems with heat, you will very clearly loose significant amounts of SQ by stacking in this way. You have all this wonderful gear. Give it room to "breathe" and footers to get rid of vibrations from/to the devices. Try some good footers such as Stillpoints, Ansuz Darkz or IsoAcoustics Orea for example. You will be surprised about the potential that is hiding in your first class components when stacking in this way.

Thank you for your feedback, yes, maybe you are right. I have the Dac and the pre away from the PSU buzz...both are on an audioplan sicomin isolation plate (imho they are great for clock devices, preamps and Phono stuff). And there is sorbothane between the gear..also between the PSU´s...(10mm). if you tipp on them, they "swimm"...before i had the XP20 and the May stacked as a couple (each with PSU)...and i like this seperate setup more. What is your opinion of keeping the MAY dac away from the PSU?

Indeed, I would keep the May away from the PSU. Less stray electromagnetic fields and less vibrations. Good that you are using isolation plates already. My experience with PSUs is that they benefit A LOT from Ansuz Darkz footers, which are quite expensive unfortunately. Since the May comes with the PSU in a separate housing - which is really excellent in my opinion - I would try to make the best out of it by moving the PSU away from the DAC and by putting both on excellent footers such as Stillpoints, Darkz, Ceraballs, Orea, or similar. I am still surprised by the enormous effect those footers can have.

Haha...yep, what made the Swiss famous by meticulously crafting even what will never hit the eye of the consumer (think watch movements before there were glass bottoms...still the movements were finely decorated), is long gone....a wrong sense of capitalism cheats the customer....just mho....

Yes, I only replaced 2 caps, you can see what I did in the darker circle areas.  The rest is factory, but the Picture makes it look way worse than it actually is with light and shadows playing together and doing crazy things.  To the naked eye it was nothing alarming.  Hand soldered I am sure.

 

So if @Toni-Mang can stack like this and have no heat issues and @dkdali had major heat issues maybe something is wrong with his dac, maybe the internal voltage switch is set wrong, or 2 pads on the Dac module are shorting or a bad component.  I'd email Tim for his perspective.

Pi2AES is crazy good for the money


Hello Chief. I am a rpi noob. If my understanding is correct, an RPI 4 with a Pi2AES hat will be a great transport for the May? Which connection is best to connect the Pi2AES to the May? 
 

Thanks a Ton!

I am using RPI4 with RoipeeeXL and Roon Core on my Qnap.  Just using the USB connection as I am hatless.  Sounds great to me and works perfectly.  I haven't tried anything else yet as I got this as it was inexpensive and worth a shot.

Since my gear is away in an open closet, I can't hear any fans. Though this one is super slow and quiet. Just moving a touch of air makes a significant difference in case temps.

After a day of 'cooling' I prefer the sound of the May at ambient 37-38C. I'll save the fan for the warmer summer months. Same goes for my amp. I have fans for when the hot summer months are here but I prefer the sound with it at it's normal temp with no air movement.

I have had my gorgeous May KTE for about 125 hours. Can anyone advise if it is worth experimenting with the orientation of the fuse?

I'm not sure it's considered to be PC speculating on the orientation of one's fuse?

Did you misinterpret what I said?

I was referring to the info on Tim's website -

Info on Red Nano Fuse type used in KTE May model:

Single crystal nano fuse
Specification: 5X20mm @2A(220v) or 4A(110v)
Withstand voltage: 250V (T) slow speed
Features: This product is complicated in process, special materials can not be made, this fuse is 100% pure handmade!
Tip: Input in different directions, the tone is different. Can try different directions

It’s certainly quick and easy to try. Try it and let us know your experience.

 

I have not tried it yet. I’m enjoying the music too much!

 

1000 hours today.

And once you are happy with its orientation, give it a good clean with an isopropyl alcohol, hold it by its glass body while inserting it into its socket/holder, and then try again... see if you can tell the difference.🙂

I don't believe fuses make a difference. Except for my AS1200 class D Amp, it was startling to say the least. So much so, I. Changed the fuse holder too!

 

But I don't believe in fuses. 

 

I changed the fuse on my Kinki integrated. I would say a gain in detail or clarity but nothing like what I experienced on my class D Amp.

 

With all the detail many of us sweat for the best SQ, the mighty fuse has to be the weakest link. The best fuse I know of is no fuse.

 

I'll at least put some nano fluid on it.
