replace alllll of them.
The MDAC is chock full of caps + heat, so they probably tried to make a significant saving per unit, and it backfired.
Maybe you have some inside information, considered opinon is that Lelon were supplied a bad batch of electrolyte.
Many large manufacturers have had problems with supplies of 'bad caps' including Samsung, Dell and others..

Some of the caps in my Mdac have failed and I have a purpose built case with 2/3 times the ventilation area.
John Westlake had a power supply board in his drawer for several years and the caps failed on that.
The MDAC cost around £ 600 and has some 60/70 caps in it at a guess.
How much would it have cost with audio quality caps ??
Weiss the price ?
It still rates as a great DAC today especially so with an internal PSU upgrade.
Sadly putting decent (not audio) caps in it would probably raise the retail price by £100 or so at least?; looking at a picture, there's 5 large ones, 24 big ones and loads of other smaller ones in it, that's a lot of cost to not simply pass on but markup, and it would have affected its sales I'm sure. If the caps went gassy even not used, then it does seem like a bad batch of electrolyte.
I tried looking for lelon caps on eBay and it said "do you mean Lemon caps?" which made me laugh
I met the opinion that reducing the condenser temperature by 10 degrees increases the service life of the capacitor by a factor of 2.
We can argue about the multiplicity of extending the service life, but the trend is obvious. IMHO.
My experience.
The price of 111 capacitors (M-DAC mainboard + PCU) for the total replacement of Lelon was about 75 .
In my opinion, when buying on e-bay, the high risk of fake capacitors.
