Well, when decent and great capacitors are available dirt cheap nowadays...
200V 1200uF 105°C rated capacitors from top brands aren't exactly "dirt cheap". I don't know where you got that information from.

$3 in quantity seems dirt cheap to me, but, assuming the BOM totals No more than $80 for this unit, including the case, an extra $4 might be a back-breaker. https://www.mouser.com/ProductDetail/Nichicon/LGU2D122MELC200V 1200uF 105°C rated capacitors from top brands aren't exactly "dirt cheap".

Yes, they were among the worst offenders during the Capacitor Plague - but, they're generally solid if unremarkable parts now. 85C is still far less than ideal in an amplifier, especially near heat sinks. I should note, though, that Jamicon and Teapo were merged together by their parent company, Kaimei - the Teapo LH series is the same caps as the Jamicon LS series according to the datasheet.Teapo as a brand were arguably the worst capacitor in terms of failure rate I have ever seen. Perhaps they have improved, but everything from small SMPS supplies, to CFL/LED supplies, laptop, PC ATX, and network hardware used them and paid the price in dead equipment.
The cheapest comparable "reputable" cap is $3ish at quantity. I can't find pricing on Teapo LH series caps, however, but Jamicon LS series are the same parts - and in Poland (the only place I could find a site selling them that isn't Alibaba), they're under $2 each in quantity. These are almost definitely good enough to get through the warranty period, which realistically is all that Crown/Harman/Samsung cares about.Well, when decent and great capacitors are available dirt cheap nowadays I don’t really see any justification on using some 85 degrees rated famous crap caps I don’t expect very expensive audiophile ones but in any device which will get anywhere near hot shouldn’t use those crap branded caps anyway
That’s exactly what I wanna say about price, I am pretty sure consumers especially pro usage in a rack will happily pay the extra $20 for that $4 cost in good caps$3 in quantity seems dirt cheap to me, but, assuming the BOM totals No more than $80 for this unit, including the case, an extra $4 might be a back-breaker. https://www.mouser.com/ProductDetail/Nichicon/LGU2D122MELC
I dunno. What do you see as the closest competitors?That’s exactly what I wanna say about price, I am pretty sure consumers especially pro usage in a rack will happily pay the extra $20 for that $4 cost in good caps
Crown is reliable with three year warranty. Sweetwater repairs the brand. You don't need to call 1-800 overseas for warranty repairs. Who really needs a 3 year out of warranty repair at this price? Crown deals with pros. Pros won't buy this model but know Crown's reputation. LG OLED have pathetic warranty. I would rather have a root canal than deal with LG "repair."You get what you pay for.
When I see some sort of plastic Ice scraper or plastic bits of the like that I know literally cost 5 cents and go for 25$, yes, I'm slightly upset but is still impressed by the team that went ahead and found such a milking cow. Now when I see people complaining about the choice of caps on a dsp capable 300$ 300W Amp, I tell myself, who on earth with it's right mind would want to get in this business with these kind of expectations for such a cheap price.

Yes, same low cost serie of amps, just more powerful. You should expect similar performance and construction. I was talking more like xti, cdi, and dsi seriesThe Crown 2502 was measured relatively recently and had similar mediocre noise and distortion performance.
If you are in the US, you can actually get 6 years right now.Crown is reliable with three year warranty. Sweetwater repairs the brand. You don't need to call 1-800 overseas for warranty repairs.

My goodnessRight now you can

Not a fan of rants and not a fan of over-generalisation either.
The temperature rating of the caps. With no knowledge about how hot the capacitors actually get in practice. Sure they are "near" a heatsink. But there is no evidence the heatsink gets particularly hot.
I noted the temperature dependency in the original write-up. Gave a pass to one set of caps for that reason. But not the other.Seriously. Does anyone think they are smarter than the guy who designed this device? Everyone is basically focussing on the one thing in the design they understand. The temperature rating of the caps. With no knowledge about how hot the capacitors actually get in practice. Sure they are "near" a heatsink. But there is no evidence the heatsink gets particularly hot. There is clearly lots of airflow, and in practice, the amp does not get hot. Yet of all the parts on the amp, it is these that are focussed on for an upgrade that clearly every buyer would, ab-initio, be pleased to pay more for, despite any proven benefit.
Well, anecdotally, my chief designer who installs more Crowns than everybody else combined, says these are unreliable.An amplifier with this pedigree will have been carefully designed and tested.
