@@MacNifty - you make some valid points. I give him the benefit of the doubt until proven otherwise. There is always a rosk in buying anything.

Being a smaller company has its perks and allows for updates to done quicker withoit red tape. As long as things are improving the customer wins in my book. As for the longevity that is a tough one. Most products today (cars included) do not last as long as older models. Most items are throw away and meant to last just past their warranty. Sad but true in my experience. When companies over build a product the warranty usually indicates that. In my case I am lookong for a couple years of usuage. Anything more is a plus in my book. By then things may have gotten better technology wise. I would like the choice to upgrade and not be forced, but you don't ever truely know unless the warranty backs it up.

Great dynamic headroom, indicative of a overbuilt amplifier! As for the caps you would be surprised how good some of those Chinese caps are. The Eton Core which is an extremely high end SQ amplifier with the lowest distortion of any amplifier in the world… It uses Chinese capacitors (Yuscon but it’s Yuscons high end line) so I think that is a good example of the Chinese making quality components. To get Genuine nichicon capacitors, you have to import them from Japan into China for amplifier assembly so it’s not just the cost of the capacitors its the cost of importing them instead of buying domestically inside of China. I would guess it would add a solid 20 bucks if not 40 bucks to the cost of the amplifier

@THELIFEOFPRICE Год назад

I understand what you are saying but I don’t want people thinking this particular amp is made in China because it’s not. It’s Korean 🙂

I ordered a jp23 refurbished amp. Removed my ctsounds ct1500.1d amp that has been faithful for 6 months. Slide the jp23v1.5 in its place, checked preamp voltage, im running oversized 1/0 ofc wire, 2 agm xs d3100 batteries. The amp blew a cap on the filter side within 5 minutes of me having the amp. Thankfully the bottom is clear and I took a picture straight out of the box. You could see the cap was leaking when I got it. So I had to send it back the same day I got it. I have sent it in and I am waiting to see what they say. I was told they would replace all the caps. I wondered why they didn't use better caps myself, the filter caps sax 25 volt caps are only .08 cents each. I trust down4sound will take care of me. Just sucks I waited a week for the amp then had to ship it right back to the repair department. I asked if I could pay the extra money for a new amp and was denied. The listing stated 1 year warranty but it only has 30 days. I'm frustrated, but as long as they make it right is all the counts. Customer service has been great to work with, he is polite and patient. However, he can only do what he is allowed to do. It's up to the company to inspect products and step up when at fault.

@Cubik303 Год назад

Better caps? A great video would be to take an amp (this JP amp would be a good candidate) and recap with high-end caps such as Nichicon or something similar. Then re-run the dyno tests and see if power or distortion specs change. There’s some work to do on selecting the correct replacement caps. Once you pull the stock caps it would be good to analyze them out of circuit for basic characteristics such as ESR. Same for the high quality replacements. Then solder in the replacements and run the dyno tests. I’m happy to help where I can (I’m a EE but not a good one, mostly do software these days because $$$) and can support with tools if needed. If you aren’t comfortable with the recap work, a local repair tech can knock it out in minutes for little coin, just bring him/her the board and caps.

They have manufacturer's warranty, which means just like any other electrical or performance parts are covered if they come or have an issue that was there when you first purchased the item, or if something else happened to it that was Not normal wear and tear during the months of warranty. So if something wears out than it's not covered under warranty. But if something unusual happens during that time it may be covered under the warranty.

@scottjames3698 3 месяца назад

"electrical or performance parts are covered if they come or have an issue that was there when you first purchased the item" That is 100% not true. I bought a $600 amp and it arrived DOA. They told me to contact the manufacturer because "it was my fault". They were rude AF about it too. From the first communication, they treated me like I was crazy for even asking for support. The manufacturer covered it because it was defective, but it cost me $70 in shipping fees, and I had to wait 4 weeks to get a new one. F Down4Sound.

As for better caps, they could make it a special/limited edition of 250 or 500 units. I dunno how much better it'd make an amp in this power range but it'd certainly be interesting to do a head-to-head. (D4S might have an arangement with their supplier that doesn't allow this subisturtion or makes it prohibitively costly) I suspect you'd need to do more than just a brute force output power test. Fidelity in, versus Fidelity out, dunno what test equipment that'd require though so perhaps it isn't a practical showdown.

@ruikazane5123 Год назад

Samyoung caps are actually decent. The company (Samyoung Electronics) is run by Nippon Chemi-Con and has two manufacturing locations, one in Korea and one over at China (excluding Chemi-Con). The caps are pretty much identical, series matching but with a different brand. Their selection probably isn't broad enough to satisfy this amp though. Otherwise, one hell of an amp!

The caps on most big brands are generic like these. For most they will never experience issues with them. Brands like Nichicon, Panasonic, Rubycon, etc. are used by techs and have lifespans of tens of years. You won't find these caps in virtually ANY amp under $2000 due to the added cost of integrating into the manufacturing process. My mention wasn't to say they are "bad", but simply a recommendation to make the amps even better than they already are 👌

@THELIFEOFPRICE Год назад

If anything happened you have warranty so don’t worry 😊

@jasoncasto910 Год назад

Higher end caps aren't going to make any difference on the rail voltage. It's the signal path where caps will shine. Also remember, there is much more to a capacitor than a name. The specs are not the same on all caps. Nichicon and other manufacturers might not make a cap specific for the needs of a particular amp or other electronic devices.

@baronvonlimbourgh1716 Год назад

Then you need to have deep pockets if you want branded caps. Probably cheaper to just upgrade them yourself to branded ones if they ever where to give you issues before you stop using the amp, which will probably will happen much earlier 👍

I've had my Sequoia for about 2 years now, but I just recently bought myself a nice system and I'm not really looking forward to dealing with all the rattles of an 18-year-old vehicle. 😂😂👍

@minus3dbintheteens60 Год назад

I think someone smarter than me can say why, but I'm sure that increasing the quality of capacitors leads to lower distortion. Just like having cooler running resistors etc can lower Johnson-Nyquist noise. I was looking into mods people have done to my DAC and the highest measurable results. Although its funny I have old Alpine amps (T757, 1505 etc) with busted open Nichicon caps but the other caps inside are fine, while I have so many different "cheaper" amps that use these special low profile Chinese caps and none have popped their top on me yet

@phillipbainbridge9107 Год назад

It wouldn't cost more than $15-20 per amp for quality caps, taking bulk purchase into consideration. Outside of the caps, everything else in the amp is also going to be lowest common denominator. Hence why similar bic lighters don't last.

@davep2945 Год назад

The issue with putting in supposedly better caps is that most people buy amps based on power and price. If someone else sells a more powerful amp for the same price or less then a lot of people are going to buy that amp thinking it is a better value. In part because most people have no idea what quality parts are. Then again, simply because we have an opinion about one brand versus another doesn't mean we're always right. Is Nichicon always better or is that simply the only name of a brand appreciated for quality that you happen to know? Do we have evidence that Yuscon is always worse or that there is a functional and meaningful difference in their caps that could be heard and appreciated in the noisy world of car audio. As enthusiasts we often assume our desire and passions are shared by everyone but that is almost never the case. If an amp lasts ten years regardless of the brand of caps within it then to most what difference does it make if it doesn't allow them more power for their dollar? And if, say, Kenwood is doing it or ROckford and you have to price your amp fifty dollars more because of the caps you use you will not sell many people into car audio on higher quality when known name brands feel that lower cost caps are just fine. Maybe D4S should do like Kenwood or JL and offer this regular line amp and a pro line like the the Excelon or Slash series with better components, better specs and a better warranty.

@2011joser Год назад

As consumers we have known Nichicons to be superior caps for decades but I wonder if we need to accept the possibility of other brands approaching existing standards. Is there any data out there that Capxcons are significantly less reliable? We now accept Korean build houses to be trusted so maybe we need trust them in their sourcing for amps in this price range. I’ve had Nichicons in Eclipse amps fail in the past while the Capxcons in my 5 plus year old Skar in daily commute use are still fine.

I doubt the cost would be that much, probably more like $10 an amp. It's a tough call I have few 30yr old amps with nichicons that are original and the amps still work great.

It could be even more than that. There are no issues with the caps used. I didn't intend for it to come off like there was. I'm asked to review and let them know how they could make them better, so this is the feedback I provide. With the fact most of the other big mfg's use generic capacitors like this, I don't see it as a problem....yet a way to distinguish them even more from the other competitors

Of course price is a big factor, but like you said, how much more for better internal capacitors?! Wouldn't that increase it's possible power delivery, reliability and whatnot? Maybe even limited runs to handle the additional cost might be worth it to some who are willing to spend a little more for actually a lot in return at least to the ones interested.... Come on! So many other things are ultra configurable now a days anyways and let the people decide what is worthwhile and maybe add a custom badge on it or something that costs little but adds more value to the buyer. 🍻🌎❤️🌮🎶
