Douk Audio G7 is Coming! TPA3255 Amplifier with a Built-in Power Supply!

[Wg916]

This thing is awesome (unlike my cable management)

Not able to take any measurements of the amp itself, but it sounds pretty indistinguishable from my other amps: 3e A7, Fosi V3 Mono, Douk A5, and Buckeye NC502mp. Which is to say that it does the intended job! Currently powering some Elac DB63s, but I tried them with BMR HTs earlier. In-room REW measurements are as expected.

I especially like the VU meters— they automatically adjust to one of three sensitivities depending on input gain from the song that is playing. So for example, if u play a song loudly, it’ll reduce the sensitivity in a few secs so the needle isn’t constantly redlining. And the same in reverse.

The best part though is the integrated 48v/10a power supply. This is one hefty amp, and the case feels like it’s of pretty good quality. I haven’t measured the heat with a thermometer, but it doesn’t/hasn’t got even slightly warm or even above room temperature. It’s been playing music for the past hour (albeit at around just 78db at 6ft). I imagine it could get cool to the touch when idle.

That $200 early bird price was an absolute steal (not sure if it’s still available). Shipped from the US on Sept 25th and arrived in California on the 28th.

I can only say: I really, really like the looks!

How is the sound, do you like it?

It does not have a sound.
It just amplifies what it put into it without imparting a sonic signature.

It should be what @solderdude says (otherwise there is something wrong with it)

As to me, I have 6 amps that produce over 500 watts RMS a channel with a 95 or better SINAD and 2 that produce about 2/3 that.
So I am amped out! I do not, at the moment, see the need for any other additional amps. But, hey, you never know!

 

[JSmith]

I wouldn't mind ordering one to check it out... not that I need more amps, but whatever.

Any chance of that $200 price again for ASR members only @Douk Audio?

I have received one as well (last weekend) and I am about to install it today in my living room powering my RP-8000F II's
Will update soon

Oh man, I’ve got the RP-8000f ii’s as well in my home theater. Mine are powered by Douk A5 48v/5a. Excellent speakers with incredible dynamic range. I imagine they’ll be clean to ear bleeding levels.

FWIW, I switched my speaker cables on the Douk G7 yesterday from L/R both on A output, to L on output A and R on output B with the G7 outputting on A+B. I believe this isolates each channel to its own TI 3255 chip, effectively like 2x monoblocks

In Italy, the price on Amazon is ridiculously high, almost 500 euros. Absolutely out of line for what it offers.

It’s $479 here in the U.S. on Amazon

I would never buy it for this price.

But for the $199 I got it for through Douk’s early bird coupon, I’d say it was a good deal.

Well, it does kind of depend on what the prices are of other competing amplifiers. I mean, I currently have the Fosi V3 mono blocks and the normal price on two of those is was little over $300 (just double checked as I wrote this and it's $289). So when you look at all the additional features of this amplifier as well as its power ratings, I would say that a price around $450 isn't really a bad ask. But remember that there's tariffs too in the US, so that's part of why the price I think is so high compared to what we were originally talking about.

You know, these speakers have absolutely incredible dynamic range and clarity of all the speakers that I have personally listened to, even at the Suncoast audio show. I have to say that these are the most well-balanced speakers I've personally heard, and they really do wonders with these little amps because they are so efficient. I made a setup for my church with the RP-8060 FA Gen 2, and after listening to those, that's how I ended up with this set of RP-8000F II.
These things go to absolutely ear bleeding volume at 75 on my DAC amp for volume so I don't foresee that this amp won't go at least that far and realistically in my normal usage I don't typically exceed 45 volume
I will be able to add the Atmos channels and put them on the top of my speakers and connect it all into this one amp, which is part of why I was so interested in it.

Thinking about it in those terms, you’re right. I think I might have had a knee-jerk reaction to seeing a manufacturer that has historically been in the “budget” category pushing a price point beyond typical of these type of amplifiers (sub-$300). $480 puts us closer to Hypex territory than most TI-based amps.

The RP-8000f ii were my initial entry into hifi (along with RP-600m ii rears). I’ve heard/purchased many other speakers since then, but they surprise me every time with clarity and effortless dynamics. Compression data from EAC also supports this.

That's a wild entry sir! I started with 1More triple driver IEMs almost 10y ago now.
Budget hypex though doesn't really seem better, most of the good hypex amps are 1k+ for 2 channel. Basic hypex without tone control or vu meters and only speaker per channel is a different device.
This amp is nice specifically because of tone Controls and 2 speakers per channel outputs and the VU meters are a nice touch... The bypasses and multiple inputs + remote and such are just icing on the cake.
I've personally looked for an amp like this for the last year.

If that were the case, the G7 would also be an option for me.
@Douk Audio can you confirm or deny this?

Really thanks for pointing this out...
$479.99 is the price with high shipping cost and high tax since G7 weighs up to 5kg and shipping to US directly from China with high tariffs.
In fact, the price will be $299.99 if it is available on Amazon US, just consistent with our official website the small bulk of the G7 is on the way and will arrive in US within one month.
I've told my colleague responsbile for Amazon US, he changed the price to $299.99 already...

 

[Douk Audio]

In Italy, the price on Amazon is ridiculously high, almost 500 euros. Absolutely out of line for what it offers.View attachment 482219

Thank you for pointing out the pricing issue.
The nearly €500 price tag is based on the original price of $479.99 (shipping directly from the US) plus 22% VAT. The reference price was incorrect; it should have been the US price of $299.99.
I've contacted Amazon Europe and they've updated the price to €369.99.

Hi, thanks for your interest in our G7.
In fact, G7 is 2 x 2.0 channel output with 2 TPA3255 chips, that means 1 3255 chip responsible for 2.0 channel.
If used like that, both TPA3255 chips are operational, but only half of each chip is active, dedicated to either the left or right channel. As a result, while this configuration does not increase the total output power, it may deliver subtle differences in sound performance.

Hi JSmith,

Thanks for your interest in our G7 and sorry for my late reply...

Sure we can provide the limited coupon code for you to buy to have a look.

I will message you soon.

 

[Douk Audio]

What exactly do the meters show (scale) ? dB, output power (if so in what impedance) ?
What characteristics ? (VU, peak, something else ?)
Do they look like McIntosh meters ?

Just for show (just swinging needles) or with actual functionality (accurately showing peaks/average levels) ?

Thanks for your comment.
But the G7's VU meter doesn't measure the true level of any signal, nor does it display accurate power output. It's more of a decorative feature and features automatic gain control. This means it automatically switches to high gain mode for low signals and low gain mode for high signals to ensure better display.

If you need to measure true level or power, you can wait for our VU2PRO (for true level) and VU3PRO Blue (for true power output). Here's a simple comparison demo video of the VU2PRO for your reference, the scale of the VU will be advised in the final version.

 

[Douk Audio]

The use of two TPA3255s with two channels and the resulting load stability of up to 2 ohms would have been the most important feature of this amplifier for me personally.
Why didn't you make this switchable so that you can switch between 2 and 4 channel operation?

Thanks for your questions, I will convey this to our PD. Any updates I will post in this thread.
