2007 had an excellent electrolytic production in the south of Japan, avoid the 2007 electrolytics from the north, it rained in May there. Southern Japanese 2007 electrolytics will ripe and become better towards 2019, if you can restrain yourself from consuming them immediatly, shelf them till 2019😉
I think "warm" or "full of life" is indeed coloration. Not a bad thing if you like it. Tube amps have a sound people like for this reason - comes from 2nd order harmonics I think which is pleasing to the ear.
Thanks for all the suggestions regarding my question in post #4766...
impuls60, could you post a link to the amp with the enclosure? - I'm not sure which one you are referring to...
I think I might try one of the danzz boards (YJ version 2.0, Danzz design) first.

I think he is talking about this one:

I have one too, and I like it quite a bit! quite friendly for modding, I particularly like the through-hole for the inductors, most boards have some kind of SMD for the inductors
My Board come out. (This is Anti-Pop design)
- ALL TH Parts
- Use DALE Axial Resistors
- Use different types of Film caps and Ecaps with power inductors
Combination I
WIMA Cap 1uF/250V x2 , 1uF/100V x 3 and Nichicon Fine Gold 1000uF/35V x 2, SAGAMI Power Inductor 10uH
Combination 2
All Siemens Film Caps and Nichincon 4700uF/35 x 2, SMT Inductor 10uH
Combination 3
Power Coil
Volume Pot. With StandBy Switch.
Bootstrap Snubbers added to New Hiamp mini 65x65mm and 65x100mm Boards, all improved pop issue under the power on/off conditions.
Coming my new finished TPA amp with Motorized ALPS Pot. + IR remote control. 🙂

Very cool with the remote!
Which combination do you like/sounds better? 1, 2, or 3?

For those wanting to change psu caps I suggest checking esr value of the one you want to swap to. Many oscon "look alike" have poor performance compared to the real thing!
Snake69fast, those caps will work but I don't know how good they are.

Thank you! I'll let you know when I will try/test them. Any suggestion what to measure on them? Do you think that they are "too old"?
Probably not too old no.. I belive aluminium organic caps doesn't dry out as fast as regular electrolytics. Perhaps others can shed some light on this subject.. I don't belive there is a simple way to measure esr without expensive equipment. The cap value will become less with age and can be measured with a cheap capacitor meter. I suggest you find out which brand and series they are and look at the specs instead to find the esr. I have searched quite a while for oscon alternatives and they are usually not as good, you have to buy them in values of 3300uF only to get twice the esr value of oscons. I've linked to cap alternatives in earlier postings🙂
You won't get competitive sound out of a 3116 compared to the ACA, when you're thinking SMPS PSU's is a cross-board comparrison. The ACA is constant current so the speed and quality of the SMPS mattersvery little. The 3116 is on demand so it makes a massive difference. Then you have to factor in the RF control being different.
I recommend ChrisMM'S amp with my rough PSU he assembled as a competitor; and maybe an Astron PSU could give some competition. SMPS's just won't cut it. They don't sound "alive" and give you the type of quality bar that expeinsive accessories of luxury cars and AV solutions aim for while not hitting audiophile grade.

Its a pity we can't perform comparisons over the Internet!
Just for the record, when we compared 3116 amps to my Mini Aleph the power supply in the first 3116 we compared was a Meanwell SMPS. We preferred the 3116 for reasons I have stated earlier. Next came a 3116 (near identical mods) with linear PS and LM338 regulator which we considered a slight improvement over the SMPS one. Later I built the Destroyer OS designed PS and found this was another distinct step up in clarity, space and dynamics.
They were my friends and my impressions, YMMV.
SMPSUs can certainly cut it provided with enough common-mode filtering. Probably the CM choke you'd have to wind yourself but it most certainly can be done.
Yes and no, just a CMC isn't enough. You need a pretty decent CLC, using more capacitence than most people think, or would like to personally handle (many people). And yet there's a few other tricks, too!
In fact there's been a lot of debate if a filter for the Mac Mini SMPS could do any justice at any price range; as of yet it hasn't happened.
Salis is the name of my forming company. The PSU hasn't been named yet.
Why don't we just submit YouTube videos like the people with guitars and what not 😛
Did you design your own CMC? If not then which commercial one did you try?
CLC's needed for a linear supply too though. With more capacitance than most people think.
Coilcraft is probably the best for selection and usefulness in audio, but there's no shortage of good CMCs. Location can control what you can get as well. Proper choice is the biggest factor.
Try? I've used and sold products with a range of coilcrafts and a few JW Miller's (now Bourne).

I found there was a shortage of CMCs able to do the job in an audio application. But then I only looked at spec sheets for most of them. So which Coilcraft choke did you try for your statement that 'just a CMC isn't good enough' ? I'd like to download its spec.
<edit> If its one that looks like these http://www.coilcraft.com/misc/bu16p.html then sure, its not enough.

The common and differential mode units are very nice, but a few CMT4 ones also fit what I look for as well.
"Enough" is a misnomer in audiophilia.... you might say. Would a CMC do good things by itself, yes, would I have like 200,000 1uf caps for the CLC, if I could?
