Yuan Jing recently introduced a complete amplifier based on their acclaimed TPA3116D2 blue amp module. This is complete with a black Aluminum case, volume pot and power supply for $88.

For those who are not comfortable slinging solder or experimenting with potentially hazardous power supplies, this amp is calling your name. In assembling a BOM with comparable parts from Mouser and Digikey including an enclosure, my total was about $100 and this does not even include a power supply.

If you want to DIY, this is still a good foundation to start with and swap in your own caps, volume pot , inductors, etc. What's funny is that an audio buddy and I were wondering when Yuan Jing was going to come out with a serious audiophile amp bearing the blue amp module. Here it is. Don't waste your time with the Yuan Jing 2.1 amp with those cheap tone controls. The blue amp is the one to get.

That sure does look like a good way to go! The amp is easily removable (no solder connections) for modding. I wonder what the PS output voltage is?
The deal breaker for me is the shipping to the NE US.

I looked at ordering one of these too but oh that shipping, especailly when you see similar being shipped for free or very little on the big auction site

I'd assume that is the same SMPS that I was talking about yesterday from YJ, 24V/5A

EDIT: guess not, I looked at the pictures again and see it is an internal PS, didn't even notice late last night when I was looking

It's probably still a better amp than you can get anywhere near the price, with that shipping. You'd have to upgrade to a TBI Millennium or something.

Salis: You may be right. It sure looks pretty sweet for $88

Who's going to be the first to jump on this?

Please know this: The freight rate I posted is to the North East US. Those on the left coast (or in between) may pay a LOT less in shipping.

I am debating ordering the finished amp but I have get over the shipping cost to NJ.

No free lunch. Folks can either build one themselves or pay to have it assembled. Can't have both.

There is no other seller providing an assembled TPA3116 of this quality (and in unmodified stereo) and this seller is more reputable than many.

Well, I'm on the West coast, only a few hours out of Vancouver and the cart quoted me even more, $52.19

Yeah, haven't seen the 2.0 in a finished assembly aside from the YJ. Onthe big auction site, I see the 2.1 but not what we want, sure better shipping rates though

Still comes out as a good deal once you consider the cost of a separate board, enclosure, and power supply which would still require you to assemble yourself. Not worth comparing to the other amps because you get what you pay for - their shipping is cheaper, but the time you have to spend to mod them or just put up with the compromised design... how much is that worth?

As mentioned above there's always the TBI Millenia for $500...

I think $150 for a solid plug and play TPA3116 is a damn good deal given the performance. If I didn't DIY I would pay that in a heartbeat.

Following this thread with great interest. Wondering how it compares with Class D Audio CDA amp. Anybody knows? Thanks!

Kind of apples and oranges as the CDA is much higher power. It's been a while since I listened to mine but I would give the edge to the TPA. Cleaner, clearer, better microdynamics, more dimensional. The CDAs are very nice though if you need that much power. They also cost a lot more.

The ClassDAudio "mini" that is in the price range sounds like a 3110 with a blanket over the speakers.

There are now a couple of ebay merchants selling the blue board. I just picked one up for $22 with free shipping.

There's also a blue board 2.1 in it's enclosure and shipped it's cheaper than the YJ.

Does anyone know of some world class diy linear powersupplies that would work well with these amps?

The Teddy PSU is probably about the best atm, but it's just the regulator that you buy. I'm trying to get some PCB's made for my own that I think may be more effective particulalry for class D.

Maybe we could get Audio gd to make an a good power supply from their DIY section of their website.

I think the trick is building a PS that can do 5-6Amps peak. Lots of great lower current options but not so much for >2Amps I've found.
So far batteries are the easiest solution for improved performance IMO.

Folsom · « **Reply #376 on:** 11 Mar 2014, 12:33 am »

A linear PSU can provide the current. But depending on what ripple you can live with you could end upward of 60,000uf. Could you hear the difference between that and 10,000uf? Factor in that only at the exact moment of the AC cycle switching will you need 100% current from capacitors, so it's rare to need full 6a worth out of them. Hence that graph is based towards non-peak, but with them in mind. It's been years since I read it's origins, but it's pretty good.

I used 6a, 7.5a shuts the amp off.

Anyone compare the sound quality to the SDS 224?

Cost aside what would be the better of them all? TBI? CDA SDS? TPA3110 with mods?

Well power needs is a factor. The TBI tops out at 30w or so IIRC, CDA from 150w to 1000w?, TPA 3110 around 8, TPA3116 around 50w (though it sounds better at 21v and under). This is for 4 ohm speakers, so less for 8 ohm (unless specified by seller).

That's a pretty wide range so depending on your setup some of them may be out of the running. I have heard all of them at some point or another. IMO conservatively speaking the YJ 2.0 TPA3116 black/blue board is at least as good as the TBI and the CDAs that I have owned. That said the CDA does have a different presentation IIRC, quite smooth, which some people may like more. But in terms of clarity and separation and overall realism I think the YJ 2.0 is tops.

Note that I say the YJ 2.0 board. NOT any of the other TPA boards, which I think require modding to sound their best. The YJ 2.0 is the best version for plug and play at this point in time IMO.

Thanks wushuliu for your reply.

I need 25w+ to drive my monitors and I did read that the YJ 2.0 is the way to go.
I have very limited soldering skills and was looking at the $88 finished version.
I will be using an iFi iTube along with the amp(s) for a buffer stage.

Can two of the YJ 2.0 units be used as mono blocks with the shorting of one input?
(This can be done with the TBI with a 20%gain in output)
