Let us know after the upgrade, if you can hear any difference. For me going from a sound card with single ended output to a balanced DAC made the biggest difference. Replacing those XLR input caps made the biggest difference in the amp, as you couldn't tell the RCA (with HF caps) and XLR (stock...

Sorry for not replying sooner :) we have used the 63V version, as they were sold here in Slovakia. the reason they are different is, that one has 2,5mm between the terminals and the second one has 5mm.They are the WIMA MKS 02. As for your other question with the coupling caps on the power...

I think, that all the SP200 have the same basic caps. They sound okay, but if you want that extra umpf, then go with the cap mod. I paired my SP200 with a cheap Chinese DAC with swapped op-amps and it is cleaner, the soundstage has more depth and height than my ASUS Xonar Essence STX sound card...

The 4 Nichicon UKZ caps are now 0,5€ a piece and the WIMA caps are also around that price, so it is around 4-5€ investment. It is maybe by 4€ more than the original caps.

@StarTreker my dad told me today to burn in for a few hours the amp, as those caps need some time - the first listening experience was (after the swap), that the sound is more agressive, there are more details and there is nothing to hold back the sound. The treble is more energetic, detailed...

Ok, so as you can see the cap swap was successful and as @Cableaddict wrote, the holes in the PCB are super small, so we had to work a bit with them. But the replacement was a success and now I am enjoying the sound 🙂

This is the thing about the entry-level gear, that to do it cost effective, they have to cut corners. But not with this type of corner cutting. :o2smile: Or that is my theory with the lower XLR input performance. I've bought a small, fully balanced dual ESS 9038Q2M DAC and after connecting it to...

I will do so :L3000:

This weekend we (me and my dad) will change the caps on the XLR inputs, also will add coupling WIMA caps. The main problem IMO with the RCA vs XLR are the used caps - RCA is using Nichicon Bi-polar ES Muse, while the XLR is using some cheap,not even audio grade caps. We will change those caps...

It's like going from really cheap interconnects that are actually not cheap enough to better quality ones. Also for me, the power cable made a big difference on the sound and the sound stage. Okay, not actually a big difference but made an improvement. :)

Same here. I've got mine for 1,5 year and when thinking about replacing it with something else I just don't want to spend a lot more for just a slight bump in the overall performance. As you wrote, you can throw anything at it and it will deliver. I bought an Xduoo MT-602 for my dad as s bday...

Yes, we don't need to have the highest ripple current capability. I talked to my dad who said, that I can have higher ripple, but I should search for the lowest ESR possible. Those 470uF are oscon caps if I am not wrong and those should be pretty good. The 2200uF caps from Panasonic are smaller...

So I made a list of caps, that I will buy and test out: 4x Panasonic EEH-AZS1E471B - Aluminium Organic Polymer Capacitors 25VDC 470uF 20% LG HiRip/LoESR for the power supply part 2x Nichicon LKG1E222MESYCK - Aluminium Electrolytic Capacitors - Snap In 2200uF 25 Volts 20% as a replacement...

But which would you recommend?

Thats why I want to replace those 4 smd caps right after the PSU and also the two 1500uF caps to have the best result. ----------------------------------------- Edit: My dad is able to replace those SMD caps. thinking about these Nichicon UKZ1E471MHM but maybe some Philips 25SEK470M or...
